А class of chemicals used for a wide range of consumer products can affect your thyroid function, according to a new study, Newsmax Health reports.  

People have widespread exposure to chemicals, which are used to manufacture items such as fabrics, carpets, cosmetics, and paper coatings. These chemicals break down very slowly and take a long time to leave the body.

For this study, researchers analyzed data from more than 1,100 people. The study looked at levels of four different PFCs as well as participants' thyroid function.

Along with finding that having higher levels of PFCs in the body can alter thyroid function in both men and women, the researchers also found that PFCs may increase the risk of mild hypothyroidism in women.

Hypothyroidism occurs when the thyroid gland does not produce enough hormones. This can lead to symptoms such as fatigue, mental depression, weight gain, feeling cold, dry skin and hair, constipation and menstrual irregularities.
