How EMFs and WiFi Can Make Your Mental Health Worse

You often hear that modern life is making us sick.

It’s true. A lot of people are suffering from diseases of civilization – including neurodegenerative and psychiatric illnesses – because there is a mismatch between our ancient physiology and the western diet and lifestyle (1). 

Most people are aware of some of the causes – poor dietary choices, nutrient deficiencies, excess stress, emotional trauma, lack of exercise, etc. 

But what if there was something in our modern environment that we couldn’t see that was making us sick?

Well, over the past several months, I’ve been learning more and more about the brain and mental health effects of man-made electromagnetic fields (EMFs). 

They’re actually a huge problem.

An increasing amount of scientific research is showing that they can cause widespread neuropsychiatric effects, including depression (2).

Learning about this inspired me to go live in the woods for 11 days. Yes, I’m serious :-) 

Read on to learn more about EMFs and my experience getting completely away from them. 

An illustration demonstrating EMFs in our environment.

Researchers and Doctors Are Sounding the Alarm about the Brain and Mental Health Effects of EMFs

“I have no doubt in my mind that at the present time, the greatest polluting element in the earth’s environment is the proliferation of electromagnetic fields. I consider that to be far greater on a global scale, than warming, and the increase in chemical elements in the environment.” – Dr. Robert Becker, MD, two-time Nobel nominee, and author of The Body Electric: Electromagnetism and the Foundation of Life

Man-made EMFs emitted by cellphones, Wi-Fi internet, and radio are considered radiofrequency (RF) EMFs. 

People can experience a wide range of brain and mental health symptoms from these EMFs, including EEG changes, sleep disturbance/insomnia, depression, headache, tinnitus, brain fog, dizziness, listlessness, irritability, malaise, restlessness/anxiety, fatigue/tiredness, concentration/attention dysfunction, memory and thinking difficulties

This has been well documented in European countries. The prevalence of EMF sensitivity in Sweden, Switzerland and Austria have been reported to be 1.5%, 3.5% and 5% respectively (2, 3, 7). 

But I suspect the amount of people who are struggling with the negative effects of EMFs is actually higher because most people are simply not aware of the problem. 

As of March 22, 2017, 225 scientists from 42 countries have signed a letter that urges the United Nations, the World Health Organization, and governments around the world to develop stricter controls on devices that emit EMFs. Altogether, these scientists have published more than 2,000 peer-reviewed papers demonstrating the biological and health effects of radiofrequency EMFs.

As a result of the increasing amount of research demonstrating the risk of EMFs, the World Health Organization has now reclassified radiofrequency EMFs as a “class 2B carcinogen”, which places it in the same carcinogenic class as lead and the pesticide DDT (4).

Some European countries have also taken action in response. Switzerland has replaced the wireless internet in schools with wired internet. In Germany, the public health department is recommending their citizens switch off WiFi when they are not using it. And Italy, France, Austria, Luxembourg, Bulgaria, Poland, Hungary, Israel, Russia and China all have set limits on radiofrequency exposure that are 100 to 10,000 times lower than US standards (5, 6). 

Meanwhile, the United States rushes forward with the wireless revolution and the rollout of 5G

What about in Canada? Not much has been done here either, even though more than 50 Canadian doctors and researchers have demanded that Health Canada raise awareness about EMFs, update their EMF guidelines, and provide resources  to assist Canadian physicians in treating people with EMF sensitivity. 

Dr. Riina Bray, medical director of the Environmental Health Clinic at the Women’s College Hospital in Toronto, has even stood in front of Canadian Parliament to bring awareness to this issue. She says:

Individuals who are sensitive to EMF, or those with electromagnetic hypersensitivity, are canaries in a coal mine and lucky enough to have discovered what it is that is making them feel unwell. Many of them find everyday life and work difficult and uncomfortable. Most often we see them with family members who thought the patient had gone mad, but then realized that what they were saying was actually true, through observations.

The question that continues to alarm me is this. What of those who have not yet become sensitized, or those who are unwell but have not realized it is the EMFs provoking the problem and continue to try to function in an environment where the electrical and magnetic fields are high?

As a physician who has specialized in the area of environmental health for over 20 years, I am mortified at the lack of accountability regarding radio and microwave radiation use in the everyday lives of Canadians both young and old. There are no longitudinal studies except the one going on right now on people who did not ask to be subjects, who gave no research ethics board consent, and on whom data is not being collected. That is not a study at all.
— Dr. Riina Bray

I highly recommend you read the full transcript here. It is eye opening.

Dr. Jack Kruse, author of author of the book Epi-Paleo Rx, also talks about the risks of man-made EMFs extensively.

And these three books discuss the issue. I just started reading the first one: 

  • Zapped: Why Your Cell Phone Shouldn't Be Your Alarm Clock and 1,268 Ways to Outsmart the Hazards of Electronic Pollution by Dr. Ann Louise Gittleman, PhD

  • Earthing: The Most Important Health Discovery Ever by Dr. Stephen T. Sinatra, MD

  • Disconnect: The Truth About Cell Phone Radiation by Dr. Devra Davis, PhD

Lastly, I highly recommend watching this TV special if you're interested in hearing more experts talk about the effects of man-made EMFs:

My Experience

Two practitioners have confirmed that I’m particularly sensitive to EMFs. 

I live and work in the city, so I bought this EMF meter to figure out the amount of EMFs I was being exposed to in my environment. 

Pathway leading toward's the cottage property.

Pathway leading toward's the cottage property.

The result? Lots of radiofrequency EMFs where I spend most of my time, including my downtown apartment. 

However, my family has a cottage property about 1.5 hours away from the city. It’s just a cabin in the woods, in the middle of nowhere, away from civilization. 

So, I recently went there with my meter to measure the levels.

The result? Dead air. Zero radiofrequency EMFs. 

I thought my meter was broken because I’m so used to it displaying a yellow or red warning signal in the city. But at the cottage property, it was green. 

So, for 11 days, I lived at this property. I’ve been very quiet on social media because of this.

I had my phone off, the Wi-Fi was off the entire time, and I connected to the Internet only sparingly using an Ethernet cable. 

I even went to the electrical panel in the basement and cut the power supply on the circuit breaker sometimes, particularly right before I went to bed. 

What did I experience from this experiment?

  • Deeper, more restful sleep – I usually never dream or remember any dreams. But I had very vivid dreams and remembered them the next morning while in the woods. This rarely happens. The last time this happened, it was when I was doing neurofeedback. I’ve since learned that neurofeedback is protective against EMFs and helps people cope with EMFs [because EMFs alter electrical activity in the brain (18-23)].

  • Complete elimination of coffee

  • Reduction in the amount of supplements I had to take – In the city, I usually need to manage some lingering symptoms with supplements and other therapies. But these symptoms faded when I completely removed myself from EMFs.

  • More mental energy and endurance

  • Increased focus

A deer I saw on my trip away from the city.

Of course, there could be other factors at play and this could have been placebo, but I really don’t think so considering the huge difference in my sleep quality and the amount of dreams I could vividly recall the next morning.

Some people may be skeptical of all this, so let me lay out some of the research showing that EMFs can affect brain function and impact mental health.

Research in Russia shows that much of the impact from EMFs occurs in the brain and nervous system, and 26 studies have associated EMFs with 13 different neuropsychiatric effects (2). 

Below are 15 specific ways EMFs can affect your brain and mental health.

1. EMFs Damage Myelin

Myelin is a fatty, white substance that wraps around the end of many nerve cells. It forms an electrically insulating sheath that increases nerve condition speeds. 

Myelin sheath.

In other words, it allows your brain to send information faster and more efficiently, making it absolutely essential for the optimal functioning of your nervous system.

This research paper explains that there is an association between EMFs and the deterioration of myelin.

The researchers say there is "an association between RF-EMF exposure and either myelin deterioration or a direct impact on neuronal conduction, which may account for many electro-hypersensitivity symptoms” (9). 

I previously provided 25 proven ways to promote the regeneration of myelin.

 

2. EMFs Reduce Cognitive Function

While I was away from the city, my cognitive function improved. I found that it was easier to read quickly. 

In 2009, researchers looked at whether EMFs emitted by cellphones would affect cognitive function.

They found that the participants that were exposed to cellphone radiation demonstrated slower response times during a working memory task (8). 

 

3. EMFs Contribute to Bipolar Disorder

Smiley faces. EMFs may contribute to bipolar disorder.

I couldn’t find any scientific research demonstrating that EMFs cause or worsen bipolar disorder.

However, I did find an amazing case study from someone named Carmen in Virginia Beach.

She explains that limiting her exposure to EMFs significantly improved her symptoms of bipolar disorder:

I was diagnosed with bipolar disorder in 2003. 

I have always taken my medications and still even with great doctors and family support, I was not able to avoid the mental hospital in 2010. 

In 2014, I started to have some odd health issues that resembled symptoms of a stroke. 

It took many months but I was able to identify the root of my symptoms: fluorescent lights, cell towers, WIFI, my cell phone and other things too. 

Nobody listened because I have a pre-existing mental condition and attributed some of my symptoms to panic attacks and OCD.

I had to stop working in due to the severity of my symptoms and I had to do a lot of changes in my house, changed WIFI for a hardwire connection straight to the router from computer, changed our home cordless phone for old fashion corded one and all my family stopped using cell phones in the house. I also had to change light bulbs and some other things. 

I realized my cell phone on my night table had been keeping me up at night because all of a sudden, I had no trouble sleeping anymore.

Now I can focus on things, I am no longer confused or forgetful, and I am not hyperactive.

Most important of all, I have not had any periods of mania, depression or hypomania since I reduced my exposures to electromagnetic fields.

You can read her entire story here

It's important to note that she mentions that she also experienced symptoms from fluorescent lights and had to change the light bulbs in her home. 

This is likely because of the negative health effects of blue LED lighting, which I previously wrote about here

 

4. EMFs Alter Brain Proteins

Research shows that long-term exposure to EMFs significantly alters the expression of 143 proteins in the brain. 

What does this mean to us?

Researchers explain that these changes may affect brain plasticity, increase oxidative stress in the nervous system, and may explain conditions such as headaches, sleep disturbance, fatigue, memory deficits, and brain tumors (13). 

 

5. EMFs Increase Anxiety

Research clearly shows that radiation from wireless technology affects the autonomic nervous system and increases anxiety and stress.

EMFs increase anxiety.

In particular, it can lead to neurotic disturbances by upregulating the sympathetic nervous and downregulating the parasympathetic nervous system (15, 17). 

In other words, it can directly increase your “fight-or-flight” response, making you chronically stressed and anxious. 

And researchers are making it clear that it’s not just “in the person’s head”. One report explains that the response to “electrosmog is physiological and not psychosomatic”. In other words, it’s really affecting the person's body. 

Unfortunately, “those who experience prolonged and severe EMF hypersensitivity may end up developing psychological problems”, stress-related behaviours and anxiety disorders due to their inability to work, and the social stigma that their symptoms are imagined rather than real (15, 16).

6. EMFs Affect Neurotransmitters

EMFs also affect neurotransmitters, the chemicals that communicate information throughout your brain.

One study found that radiation from cellphones significantly disrupts levels of serotonin, dopamine and norepinephrine in the brain. 

The researchers concluded that this may be why people report that they experience stress, memory problems and learning difficulties from EMF exposure (14). 

 

7. EMFs Affect Thyroid Function

Your thyroid is a small butterfly-shaped gland located in your neck below your Adam’s apple.

An illustration showing the location of the thyroid gland.

As I discussed before, your thyroid gland plays a key role in the optimal health and functioning of your brain. It can impact your cognition, concentration, mood, memory and emotions.

Researchers have found that EMF exposure can affect the structure and functioning of the thyroid gland (10). 

One study found that heavy cellphone users have higher than normal TSH levels, and lower than normal T4 levels. These abnormal levels are linked to thyroid dysfunction and hypothyroidism (low thyroid) (11). 

Here are some of the brain and mental health symptoms of low thyroid that I’ve experienced:

  • Chronic fatigue

  • Brain fog

  • Low mood

  • Forgetfulness

  • Weakness

  • Sluggishness

Not surprisingly, these are also common symptoms of EMF hypersensitivity.

Check out this post for ways to support your thyroid.

My favourite way is by applying this red and infrared light to my thyroid. 

 

8. EMFs Increase Risk of Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) is characterized by inattention and hyperactivity.

Yale researchers have determined that cellphone use during pregnancy affects the brain development of offspring, and this can lead to symptoms of ADHD in the children once they are born (12). 

This is the first experimental evidence that fetal exposure to radiofrequency radiation from cellular telephones does in fact affect adult behaviour. The rise in behavioral disorders in human children may be in part due to fetal cellular telephone irradiation exposure.
— Dr. Hugh Taylor, MD
 

9. EMFs May Worsen Symptoms of Autism

A report published in the journal Pathophysiology points out that autism involves many biological disturbances that are very similar to the physiological impacts of EMFs and radiofrequency radiation.

The researchers even say that reducing EMF exposure might reduce symptoms of autism.

With dramatic increases in reported autism that are coincident in time with the deployment of wireless technologies, we need an aggressive investigation of potential Autism/EMF/RFR links. The evidence is sufficient to warrant new public exposure standards benchmarked to low-intensity (non-thermal) exposure levels now known to be biologically disruptive, and strong, interim precautionary practices are advocated.
 

10. EMFs Reduce Melatonin and Disrupt Sleep

Melatonin is a hormone released by your pineal gland, a small gland in your brain. It helps control your sleep and wake cycles (circadian rhythm), and adequate levels of melatonin are necessary to fall asleep quickly and sleep deeply throughout the night.

Melatonin acts as a very potent antioxidant in your brain and can protect against a number of neurodegenerative and mental health conditions (26). 

Reduced levels of melatonin are associated with depression and suicide, seasonally affective disorder (SAD), schizophrenia, Alzheimer’s disease and Parkinson’s disease (24). 

Cellphone next to a woman sleeping. EMFs negatively affect sleep.

Unfortunately, 17 independent studies have found that EMFs disrupt the body’s circadian rhythm and natural production of melatonin, leading to sleep difficulties and many adverse health effects (25, 27-31). 

Researchers say that the evidence is “substantial and robust” and “there is a sound scientific basis for concluding that” acute and chronic EMF exposure lowers melatonin production, leading to very serious health effects, including depression (25, 32). 

That’s why you should turn off all Wi-Fi before bed. I live in a downtown apartment with lots of radiation coming from all the apartments around me, which likely explains why I slept so much better in the woods.

This sleep supplement contains magnesium and a number of other natural compounds that I’ve used over the years to promote the production of melatonin.

But I work with my clients so that they can naturally produce more melatonin and maximize the quality of their sleep without so many supplements. We have free online workshop that talks about how you can work with us. You can register for the workshop here.

11. EMFs Increase Brain Tumors

The National Toxicology Program conducted a large, complex, two-year study on the potential health hazards of cellphone use. They found that RF and EMF exposure increases brain tumors in rats, mice, and humans (50-51). 

Sweden researchers have also published a meta-analysis showing a significant association between long-term cellphone use and both malignant and benign brain tumors (52). 

 

12. EMFs Disrupt the Blood-Brain Barrier

The blood-brain barrier is a protective shield that surrounds your brain. It acts as a gatekeeper and filter, allowing beneficial nutrients to cross over into your brain, and keeping unwanted molecules out of your brain.

A leaky brain. EMFs disrupt the blood-brain barrier.

In his book Why Isn’t My Brain Working, Dr. Datis Kharrazian explains that the blood-brain barrier can break down and become “leaky”. This allows harmful substances to enter your brain, contributing to brain inflammation, which has been shown to cause cognitive problems and mental illness.

A number of factors contribute to “leaky brain”, including electromagnetic fields. 

Radiofrequency EMFs emitted from cellphones have been shown to increase the permeability of the brain-blood barrier in several studies (33-34). 

And this increased permeability may lead to the accumulation of brain tissue damage and cognitive impairment (33, 35). 

I previously provided ways to support and repair the blood-brain barrier in this post

 

13. EMFs Increase Risk of Depression and Suicide

About 10 studies have reported an association between exposure to EMFs and depression (36, 37). 

A woman with depression. EMFs contribute to the rising rates of depression.

In a few of those studies, researchers found a specific correlation between living near a cellphone base station and severity of depressive symptoms (38-40). 

In another study, researchers looked at personnel at the U.S. embassy in Moscow who were exposed to EMFs, and they found that there was a statistically significant increase in depression (41). 

People working around radiofrequency EMFs are also more likely to suffer from depression and commit suicide (42-45). 

A good way to combat this is by supplementing with rhodiola. I previously wrote about how it’s a good antidepressant, but it’s been shown to be radioprotective as well (60-62). 

 

14. EMFs Increase Free Radicals and Oxidative Stress  

Free radicals are unstable molecules that damage cells and contribute to brain damage, aging and mental disease (46-47). 

Oxidative stress is when there is an altered balance between free radicals and their elimination by antioxidants.

After an extensive literature review, researchers have concluded that EMF exposure increases levels of free radicals and oxidative stress in the body, leading to acute and chronic health effects (49). 

In another study, researchers found that EMFs are an “oxidative stressor and DNA damage inducer” (48). 

Long-term EMF exposure has also been shown to lead to a chronically increased level of free radicals, reducing the effects of melatonin in the brain (49).

 

15. EMFs Linked to Dementia

Dementia is the third leading cause of death in the United States behind cardiovascular disease and cancer, and by 2050, it’s estimated that 13 million Americans and 160 million people globally will be affected by the disease.

Unfortunately, there are more than 70 studies linking EMFs to dementia, and this number is likely to rise as time goes on, along with the number of diagnoses (53). 

The research also includes several epidemiological studies and meta-analyses that link exposure to EMFs and Alzheimer’s onset (55). 

An elderly man sitting and thinking. EMFs contribute to dementia and cognitive decline.

Researchers have found that overnight exposure to EMFs significantly increases the secretion of amyloid-beta, a peptide that is involved in the development of Alzheimer's disease (54). 

EMF exposure also negatively affects the “entorhinal cortex”, the area of the brain that is first affected by Alzheimer's disease (56-57). 

Lastly, animal studies show that EMFs decrease learning and memory and cause cognitive deficits (58-59). 

I previously wrote a post with some ways to reverse cognitive decline and dementia. You can check that out here

 

Conclusion

If we continue to develop our technology without wisdom or prudence, our servant may prove to be our executioner.
— Omar N. Bradley
What EMFs would look like if you could see them.

What EMFs would look like if you could see them.

My vacation in the woods is now over, and I’m currently back in the city. 

I’m certain I’m sensitive to EMFs now, and it’s definitely impacting the quality of my life.

I really hope I don’t scare people with this post. But I do think it’s something that should be on your radar. 

At this point, I still don’t have too many recommendations to combat EMFs, other than the ones I already mentioned in my previous post about myelin (see step #25 in that post). 

But I plan on researching more and putting together a complete protocol that I’ve personally tested myself, so that you can also protect and shield yourself from EMFs!

So, stay tuned for that in an upcoming article.

20 Proven Ways to Quickly Lower Your Cortisol Levels

A man looking depressed and stressed, hoping to lower his cortisol levels.

Chronic stress is killer. 

It broke me down over the years and led me to deep depression.

Getting a handle on it has been critical to my recovery. 

But it took me a while to figure out what works.

And I’d rather not see other people struggle and frantically look for solutions.

So I’ve gathered some of my favourite ways to quickly lower levels of cortisol, your body’s main stress hormone.

But before we get to them, let’s quickly discuss cortisol and how chronically high levels of cortisol can negatively affect your brain and mental health. 

 

How Stress and Cortisol Affect Your Brain

Cortisol is known as the “stress hormone”.

It’s a naturally-occurring steroid hormone that’s produced by your adrenal glands and released when you’re under physical or mental stress. Essentially, it triggers our fight-or-flight response in stressful situations.

But it’s also absolutely necessary for our health, as it plays a key role in many different bodily processes. 

Cortisol levels are generally highest in the morning and lowest at night. But problems can arise when they are elevated for prolonged periods of time (134). 

Chronically high cortisol levels can:

  • Change the size, structure and functioning of your brain;

  • Shrink and kill brain cells;

  • Cause premature aging in the brain;

  • Contribute to memory loss and lack of concentration;

  • Slow down our ability to grow new brain cells; and

  • Increase inflammation in the brain (135-140).

Watch this TED-Ed video, How Stress and Cortisol Affect Your Brain,” to learn more: 

Chronic stress and high levels of cortisol also increase activity in the amygdala, the fear centre of the brain. This can create a vicious cycle in which the brain is more likely be get stuck in a constant state of fight-or-flight.

When I did neurofeedback, my practitioner discovered my amygdala was overactive. She trained it back down to normal levels, and my chronic anxiety dissipated.

Anxiety isn’t the only mental condition linked to an abnormal stress response. Here are some others:

Luckily, there are a number of ways to manage and overcome chronic stress, lower cortisol levels, reverse damage done to the brain, and improve your sense of wellbeing. 

This article includes the best foods, nutrients, herbs and supplements that reduce cortisol; as well as the best lifestyle habits, therapies and practices that reduce cortisol.

Let’s go through them.  

 

The Best Foods, Nutrients, Herbs and Supplements To Naturally Lower Cortisol Levels

1. Eat Dark Chocolate

two pieces of dark chocolate. eating dark chocolate can lower your cortisol levels.

Most people know that dark chocolate is rich in multiple antioxidants, such as flavonols and polyphenols, which reduce oxidative stress.

But it also reduces cortisol. 

This may explain why people love to eat chocolate and experience relaxation when they do. 

Dark chocolate can protect your brain by boosting BDNF, your brain’s growth hormone

You should always try to get raw dark chocolate with the least amount of sugar.

 

2. Drink Tea

Several different types of tea have beneficial effects on cortisol levels. 

Green tea has been shown to inhibit the synthesis of cortisol (18). 

And a study found that individuals who drank 4 cups of black tea daily for six weeks had lower cortisol levels in comparison to others who didn’t drink black tea (2). 

Researchers couldn’t confirm what caused this reduction in cortisol, but they suspected it had something to do with the high content of theanine, an amino acid found in both black and green tea.

A follow-up study published this year confirmed that theanine can reduce cortisol (13).

Theanine produces a calming effect on the brain by crossing the blood-brain barrier and increasing the production of both GABA and dopamine in the brain (12). 

I personally can’t drink most teas because they tend to contain mycotoxins (mold toxins) and I’m very sensitive to them after living in a moldy home.

If you’ve lived in a moldy home or have found out that you’re genetically susceptible to mycotoxins, you can supplement with straight theanine like I do. 

This supplement includes theanine. 

And if you do decide to drink black tea, you can lower cortisol even more by getting decaffeinated black tea.

Lastly, chamomile tea is another type of tea that can decrease cortisol. It’s been used for centuries as a sleep aid. It contains flavonoids, essential oils, coumarin and other compounds that can help you relax.

Several studies show it can block the precursor hormone of cortisol and improve sleep quality (14, 15). 

This anti-anxiety supplement includes theanine, along with a number of other natural compounds that have helped me manage my stress and anxiety over the years.

 

3. Eat Extra Virgin Olive Oil

Olive oil has numerous health benefits, particularly because of its strong anti-inflammatory effects.

It also contains a compound called oleuropein, which can reduce cortisol levels (37). 

I add it to my salads and sometimes even take a tablespoon of it straight.

Be careful though. A lot of cheap extra virgin olive oil in grocery stores are not actually “extra virgin.”

Investigations have found that there is a lot of fraud within the olive oil industry and many so-called extra virgin olive oils contains other cheaper, refined vegetable oils, such as soybean, corn and canola. 

This is discussed more in the book Extra Virginity: The Sublime and Scandalous World of Olive Oil

 

4. Take Cortisol-Reducing Nutrients and Herbs

There are a number of nutrients, vitamins, minerals and adaptogenic herbs that have been shown to reduce stress and cortisol levels. 

I’ll go over some of my favourites here.

Phosphatidylserine is probably the best option for reducing stress hormone levels. 

Phosphatidylserine is a fat-soluble amino acid compound that plays a key role in optimal cognitive function. High amounts of phosphatidylserine can be found within the brain, and supplementation has been shown to improve attention and memory, especially in the elderly (114-116). 

…consumption of phosphatidylserine may reduce the risk of dementia and cognitive dysfunction in the elderly.
— Food and Drug Administration

On top of all this, phosphatidylserine powerfully lowers cortisol (117-119). 

People who supplement with phosphatidylserine have been shown to have lower average levels of cortisol (120).

I take phosphatidylserine every day. It's part of the Optimal Calm supplement

Ashwagandha is another great cortisol-reducing supplement. It’s a popular Indian herb commonly used to prevent anxiety. Its anti-anxiety effect is synergistic with alcohol.

Its stress-reducing effects are likely because it lowers cortisol levels. 

Multiple studies have concluded that it is a potent stress reliever that can reduce cortisol by anywhere from 14 to 32% (121-123). 

Ashwagandha is included in this supplement.

Another adaptogenic herb that can lower cortisol is rhodiola. 

The rhodiola rosea plant. Rhodiola can lower cortisol levels if your cortisol levels are high.

I’ve discussed rhodiola before. It can really help with symptoms of depression. 

Research has found that it may be doing this by significantly reducing stress hormone levels in the body (124-126). 

Lastly, a number of minerals have been shown to reduce cortisol, including zinc, magnesium and selenium (96, 97, 127-133).

That’s why I take and recommend a multi-mineral supplement every day

Overall, ashwagandha, rhodiola, phosphatidylserine and minerals are my favourite ways to keep stress levels low, but there are plenty of other supplements that have been shown to positively affect cortisol levels, including:

 

5. Consume Enough Food, Protein and Water

Water from a water bottle being poured into a glass. Drinking enough water can reduce stress and lower cortisol levels.

Eating enough protein and calories, and drinking enough clean, filtered water is also critical to keeping stress hormone levels low.  

Studies show that severely restricting calories elevates cortisol levels (108, 109). 

Restricting protein and depriving yourself of the amino acid leucine can also stimulate the stress response and increase stress hormones (110). 

That’s why I eat plenty of food each day and supplement with creatine and BCAA protein powder throughout the day when I don’t have access to a source of high-quality protein. 

Lastly, make sure you stay hydrated and drink plenty of water.

Properly-hydrated runners have noticeably lower cortisol levels than dehydrated runners (81).

I use a high-quality filtration system to filter my water so that it’s as pure as possible.

6. Consume More Omega-3s and Less Omega-6s

As I’ve discussed before, omega-3s are dietary fats that are needed for the proper functioning of your brain and nervous system. They improve learning and memory, and protect against psychiatric disorders including depression, mild cognitive impairment, dementia and Alzheimer's disease (4-7). 

Researchers have also found that when individuals supplement with omega-3 fatty acids, there is a significant reduction in the release of cortisol (1, 10).

Omega-3 fatty acids also significantly reduce stress hormones in animals (3). 

Krill oil is my favourite source of omega-3 fatty acids.

I also eat wild salmon and grass-fed beef on a regular basis. 

On the other hand, consuming too many omega-6 fatty acids have been linked to increased inflammation and cortisol levels (8, 9, 11).

So make sure to avoid refined vegetable oils such as soybean, corn, safflower, sunflower, and canola oil.

 

7. Get Enough Antioxidants

Berries, including raspberries, blackberries and strawberries. The antioxidants in berries can lower cortisol levels.

Not only do antioxidants counteract oxidative stress within the body; they can also help reduce cortisol (19, 25). 

Most of the research has been done in athletes, but supplementation with antioxidants – such as berry powders, greens powders, vitamin C, glutathione and CoQ10 – leads to fairly significant reductions in cortisol and other measures of stress (20-23). 

Dark berries in particular contain antochyanins, which have been shown to lower cortisol (24). 

Acai berries are my favourite, as they are loaded with antochyanins and vitamin C.

Regarding vitamin C, the research is mixed on whether it can consistently lower cortisol levels.

However, in my experience, high doses of vitamin C definitely reduce stress.

One study found that a high dose of vitamin C decreases anxiety and improves mood (29). 

After exercise, it’s also been shown to rapidly reduce cortisol (26, 27). 

And multiple other studies have found that both vitamin C and vitamin E reduce cortisol and anxiety (30-32). 

It’s also well known that chronic stress and high cortisol can deplete vitamin C and other antioxidant enzymes (28). 

In addition to getting vitamin C from fruits and vegetables, I take at least 500 mg of supplemental Vitamin C every day. I’ve experimented with taking up to 10 grams daily (2 gram doses throughout the day) and it helped me manage stress, but it’s not necessary unless you find it really helps you. 

Vitamin C and Vitamin E are both included in this supplement, along with several other antioxidant nutrients.

 

8. Take Curcumin

Curcumin is the most heavily researched compound within turmeric, the spice that gives curry its yellow colour.

Curcumin is one of my favourite compounds for the brain and mental health.

Thousands of high-quality scientific studies have been published, showing that curcumin has anti-inflammatory and antioxidant effects and can increase BDNF, your brain’s growth hormone. 

Research shows that curcumin inhibits the increase in cortisol caused by stress (33, 34). 

And animal studies have found that curcumin may reverse elevated cortisol levels after chronic stress (35, 36). 

Unfortunately, curcumin is very inefficient at absorbing into the bloodstream and reaching the brain (54, 55).

Luckily, science and technology has been able to concentrate significant amounts of curcumin into supplement form and increase its bioavailability. 

I get my curcumin from the Optimal Energy supplement.

Since curcumin is a fat soluble, I take it every day with a fatty meal.

 

9. Eat Prebiotic Foods

A picture of blue bacteria. Prebiotics feed to the good bacteria in your gut and have been shown to lower cortisol levels.

Prebiotics are substances in food that humans can't digest, so they pass through our gastrointestinal tract and promote the growth of many different strains of good bacteria in our lower bowel.

They are essentially food for the probiotics in our intestines.

Dr. Phil Burnet, a neurobiologist at Oxford University, published a paper in 2015 showing that people who ingested prebiotics have lower levels of cortisol.

The people who ingested prebiotics also focused more on positive feedback and less on negative stimuli.

Dr. Burnet said the results were very similar to when people take anti-depressants and anti-anxiety medication, but without the side effects (87).

That’s why I eat prebiotic-rich foods regularly, including sweet potatoes, carrots, onions, asparagus and squash. These foods are included in my free grocery shopping guide for optimal brain health. 

Resistant starch is one of the most potent ways to boost your prebiotic intake. A convenient way to incorporate more of it into your diet is by using and eating potato starch. Other high-quality resistant starches include banana flour, plantain flour and waxy maize. Cooked and cooled white rice and potatoes also contain some resistant starch. 

I previously discussed prebiotics and resistant starch here.

I also created and take Optimal Biotics, which is a premium probiotic supplement that reduces stress and support my mental health. 

 

10. Limit Alcohol and Caffeine

A cup of coffee on a plate with a spoon. Avoiding or limiting your coffee and caffeine consumption is a good idea if you want to lower your cortisol levels.

Excess consumption of alcohol and caffeine have been shown to increase stress hormones, so their consumption should be limited. 

Coffee is definitely good for brain health. There is a lot of research showing it is very healthy and can be protective against dementia

However, it can also disrupt sleep and make people anxious. I used to not be able to handle any coffee at all. But now that I'm healthy, I can handle it just fine. I drink one cup of high-quality coffee most mornings.

But if you’re struggling with high cortisol and chronic stress, I wouldn’t recommend high doses of caffeine.

It’s been shown to directly stimulate the adrenal cortex, release cortisol into the bloodstream and increase stress hormone levels (74-76).

One study found that caffeine increased cortisol by 30% in just one hour, and regular consumption can double your cortisol levels (88, 89). 

So limit it as much as possible.

An alternative solution is to consume the whole coffee fruit, instead of drinking coffee.

The coffee fruit doesn’t contain caffeine, but it does contains several healthy compounds not found in coffee beans themselves.

Scientists have discovered that ingesting whole coffee fruit concentrate significantly increases brain function. Coffee fruit concentrate can be found in the Optimal Brain supplement

Lastly, excess alcohol consumption over an extended period of time has also been shown to raise cortisol levels. Having a couple drinks here and there likely isn’t a problem though, and you can protect yourself from it by following these steps (90, 91). 

Certain types of alcohol are better to drink than others.

The Best Lifestyle Habits and Practices to Naturally Lower Cortisol Levels

11. Laugh

In the book The Anatomy of an Illness as Perceived by the Patient, Norman Cousins explains how he cured himself of ankylosing spondylitis by laughing along with Marx Brothers movies.

I made the joyous discovery that ten minutes of genuine belly laughter had an anesthetic effect and would give me at least two hours of pain-free sleep. When the pain-killing effect of the laughter wore off, we would switch on the motion picture projector again and not infrequently, it would lead to another pain-free interval.
— Norman Cousins

It sounds farfetched, but more and more research is showing that laughter has a powerful effect on our health. 

Researchers have found that laughing and having fun significantly reduces stress hormone levels (65, 66). 

In one study, laughter improved the short-term memory of older adults, and simply anticipating humour decreased their cortisol levels by nearly 50% (64). 

So, next time you’re stressed, try watching a funny TV show or YouTube video

 

12. Play with Animals

This is my cat named Puddy. He's annoying but he does reduce my cortisol levels.

This is my cat named Puddy. He's annoying but he does reduce my cortisol levels.

Petting your own dog or another person’s dog has been shown to significantly decrease stress hormone levels and increase oxytocin, endorphins, and other healing hormones (71, 73). 

Researchers have also compared 20 minutes of quiet rest to 20 minutes of interaction with a dog, and they found that hanging out with dog contributed to a much more significant decrease in cortisol. This is often why therapy dogs show up on college campuses during exams (71). 

So you should try to hang out with animals as much as possible, and consider getting a house pet if you don’t have one. I have a cat named Puddy. 

Spending time in nature has also been shown to reduce cortisol levels. So you can kill two birds with one stone by taking your pet for a walk in the park (77). 

Hmm perhaps “kill two birds with one stone” wasn’t the best idiom to use in this section, but you get my point. 

 

13. Listen to Music and Dance

Music is actually healing and can have a calming effect on the brain. 

Numerous studies show that music can relax you, especially before a stressful event, by significantly lowering stress hormones. It can also reduce the spike in cortisol during the stressful situation (50-54). 

Music can be even more relaxing when combined with non-strenuous dancing.

Regular dancing has also been shown to greatly decrease cortisol levels (55). 

 

14. Practice Relaxation Techniques and Therapies

Not too surprisingly, simply taking time each day to relax can lower cortisol.  

My favourite relaxation technique is meditation. 

Countless studies show that meditating daily for just 15 minutes can significantly lower stress hormone levels and blunt cortisol spikes (38-43). 

I use the Muse headband to meditate. Similar to neurofeedback, it gives you real-time feedback on your brainwaves. I previously wrote about it here, and you can get it through the Muse website

Yoga has also been shown to lower cortisol. 

In one study, people with depression practiced yoga regularly for 3 months. By the end of the study, their cortisol levels dropped significantly and they experienced relief from their depression (44). 

Massage is another excellent option, as it’s been shown in many studies to significant decrease in cortisol and anxiety (45, 46). 

A woman is lying down and getting a massage/ Massages can lower your cortisol levels.

I get a massage every couple of months. 

Emotional Freedom Technique, or “tapping”, is another tool I use to manage stress

Tapping is based on ancient Chinese acupressure and modern psychology. You can learn how to practice it here

I know it seems hokey, but it works. 

It’s been shown to significantly decrease cortisol levels (47). 

The book The Tapping Solution: A Revolutionary System for Stress-Free Living goes in more depth about the practice. 

Lastly, deep breathing exercises can help you manage your stress hormone levels. 

Diaphragmatic breathing – consciously breathing from your diaphragm – has been shown to encourage the body’s natural relaxation response and reduce cortisol (48, 49). 

I use the EmWave2 device every day to reduce stress and make sure I’m breathing optimally. I wrote about it before here.

 

15. Exercise (But Not Too Much)

Exercise is definitely good for you. It can balance hormones and reduce stress by releasing endorphins. However, overtraining can actually backfire and increase stress hormone levels (112). 

That’s why I don’t really recommend chronic endurance exercise and prefer weightlifting and high-intensity sprinting over cardio. 

Research shows that prolonged aerobic exercise can increase cortisol levels, and marathon runners have higher levels of cortisol (111, 113).

16. Get More Deep Sleep

This might be the most important step. 

Getting enough high-quality sleep is critical for your brain and mental health. 

My sleep used to be terrible and it was one of main factors that contributed to my poor mental health. And then my poor mental health would make my sleep worse. So it was a vicious cycle. 

Let me explain.

A woman is sleeping. Sleep can lower your cortisol levels.

Normally, cortisol increases in the morning and then drops very low at night prior to bed. But if you have chronic stress and high cortisol, you can end up feeling wired and anxious at night, making it more difficult to sleep. 

Unfortunately, staying up late when your body expects to be asleep further increases your stress hormone levels even more. And lack of sleep and interrupted sleep have been shown to significantly increase cortisol throughout the next day and contribute to cognitive problems down the road (56-61, 63). 

So it’s clearly a vicious cycle where high cortisol causes sleep problems, and poor sleep increases stress.  

That’s why it’s so important go to bed at the same time every night and aim for at least 7 hours of sleep every night. Without doing that, you can end up with dysregulated daytime cortisol production.

And it’s not just the amount of sleep you get that’s important. It’s also the quality of sleep. In fact, the quality of your sleep is more important than the length of your sleep.

So I would try doing everything you can to maximize the quality of your sleep. 

I share my very best sleep tips with my clients through our Brain Recovery Accelerator Program. We have a free online workshop that talks about the program. You can register for the workshop here.

You could also take this sleep supplement, which contains magnesium and a number of other natural compounds that I’ve used over the years to improve sleep.

And if you don’t get enough sleep one night, try to take a nap sometime the next day. Daytime napping after a night of sleep loss has been shown to cause beneficial changes in cortisol levels (62).

 

17. Chew Aspartame-Free Gum

Next time you’re stressed, try chewing a piece of gum. 

It’s an easy way to lower your stress hormone levels. 

According to one study, chewing gum while under moderate stress reduces mental stress and decreases cortisol by 12 per cent. Previous studies have also shown that chewing can increase alertness, neural activity and blood flow to the brain (82). 

I prefer if the gum is aspartame-free.

 

18. Stand Tall

Changing your body language can have a powerful effect on your biology. 

Standing tall for just two minutes can lower your cortisol by 25 per cent, according to a famous study led by Harvard social psychologist Amy Cuddy (83). 

Cuddy’s research found that if you switch from low-power body language (arms crossed, hunched over, closed up, slumped shoulders, nervous) to high-power body language (opened up, tall, relaxed, confident), your hormones will change to match your new posture (84). 

So try your best to maintain high-power body language as much as possible as it can reduce stress hormones and increase confidence. You could even try holding a dominant pose for 2 minutes every day. You’ll likely find yourself feeling calmer and more mentally powerful.

And if you haven’t already, check out Amy Cuddy’s TED talk “Your Body Language Shapes Who You Are”.

I also recommend her book Presence: Bringing Your Boldest Self to Your Biggest Challenges.

19. Socialize

Social connectivity and positive social interactions also significantly reduce stress hormone levels.

Research shows that the more social support a person has, the lower their cortisol levels will be (67). 

This is likely because you release the hormone oxytocin during social contact and social bonding, and oxytocin has been proven to decrease anxiety and block increases in cortisol (68). 

One study states that “the combination of oxytocin and social support exhibited the lowest cortisol concentrations as well as increased calmness during stress” (69). 

Animal studies have also discovered that social isolation leads to higher cortisol and mental health problems (70). 

Make sure to check out my full article about oxytocin to learn more about this powerful neurotransmitter.

 

20. Other Cutting-Edge Therapies

Here are some other therapies that have been shown to reduce stress and cortisol:

  • Bright Light Therapy (85, 86).

  • Transcranial direct current stimulation (78)

  • Transcranial magnetic stimulation (79, 80)

  • Acupuncture (92)

 

Conclusion

It’s important to take control of your stress before it takes control over you.

Thankfully, there are so many ways to manage your stress and lower cortisol levels without having to resort to a prescription

Here’s a summary of everything we’ve gone over to reduce stress hormone levels:

A person is squeezing a stress ball. The stress ball looks like and is in the shape of a brain.
  • Eat wild salmon, grass-fed beef and krill oil, and avoid refined vegetable oils

  • Drink black, green and chamomile tea, or supplement with theanine

  • Eat dark chocolate :-)

  • Get enough antioxidants, including vitamin C, vitamin E, glutathione and CoQ10

  • Eat turmeric and/or supplement with curcumin

  • Add extra virgin olive oil to meals

  • Relax with meditation, the Muse headband, yoga, massage, tapping, deep breathing, and the EmWave2

  • Listen to music and dance

  • Sleep deeper

  • Watch comedy and laugh

  • Socialize

  • Play with animals

  • Chew aspartame-free gum

  • Stand tall with powerful body language

  • Limit alcohol and caffeine

  • Eat prebiotic foods, including resistant starch

  • Eat enough food and protein

  • Drink enough filtered-water

  • Exercise, but not too much

  • Supplement with phosphatidylserine, ashwagandha, rhodiola and/or minerals

I remember when I first discovered all of these tools and strategies, it gave me so much hope that I could get better and overcome my depression and anxiety.

And I thankfully I did.

And you can too. 

Let me know what you think in the comments. Have you ever had high cortisol? Do you have any other tips that have helped you reduce cortisol?
