Cell phone frequency radiation significantly reduced thyroid hormone levels in rats after just 4 weeks of daily exposure.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to 900 MHz radiofrequency radiation (the same frequency used by cell phones) for 30 minutes daily over 4 weeks and measured thyroid hormone levels. They found that EMF exposure significantly decreased levels of TSH (thyroid stimulating hormone) and T3-T4 thyroid hormones compared to unexposed rats. This suggests that cell phone radiation may disrupt normal thyroid function, which controls metabolism, energy levels, and many other bodily processes.

Study Details

In this study, the effects of exposure to a 900 megahertz (MHz) electromagnetic field (EMF) on serum thyroid stimulating hormone (TSH) and triiodothronine-thyroxin (T3-T4) hormones levels of adult male Sprague-Dawley rats were studied.

Thirty rats were used in three independent groups, 10 of which were control (without stress and EMF)...

TSH values and T3-T4 at the 900 MHz EMF group were significantly lower than the sham-exposed group (...

These results indicate that 900 MHz EMF emitted by cellular telephones decrease serum TSH and T3-T4 levels.
