So your thyroid soaks them up and uses them like iodine.
By occupying iodine receptors, they worsen iodine deficiency, inhibit the production of your thyroid hormones and contribute to thyroid dysfunction.
Studies show that chlorine interferes with proper conversion of thyroid hormone (50, 58-61).
That’s why I recommend filtering your drinking and shower water. Brita filters aren't enough because they don’t remove fluoride. I use this Berkey water filter to make sure I’m drinking the purest water available. It filters everything out of the water. I also use this filter to remove chlorine from my shower water.
The research shows that bromide in particular can cause a lot of problems. Bromide is found in pesticides, prescription medication, plastic products and personal care products. PBDE (bromide) fire retardants have been added to mattresses, carpeting, electronics, furniture and car interiors since the 1970s.
Even small amounts of bromide can be problematic, depleting iodine and weakening the thyroid gland. Bromide levels are 50 times higher in thyroid cancer than normal thyroid tissue, and elevated levels of bromide have been linked to mental illness, including depression and schizophrenia (50-57).
12. Avoid Environmental and Dietary Mycotoxins
Mycotoxins – toxic metabolites produced by mold – can also disrupt normal thyroid function.
Mycotoxins are released into the air in water-damaged buildings, and you may not realize it’s affecting your brain and thyroid health until you develop certain symptoms. And even then, people frequently won’t make the connection between the mold and their health.
That’s what happened to me, and my hormonal health went downhill, along with my brain and mental health. Luckily I’ve recovered since then.
Mycotoxins are known hormone disruptors that cause inflammation, and a couple of studies mention that there is an increased frequency of “thyroid, immune dysfunction and autoimmune conditions” in people exposed to water-damaged building (41, 42).
