Having problems sleeping? Maybe its not your CRONing diet & you need to check the EM field strength in your bedroom?
================================
A 50-Hz electromagnetic field impairs sleep.

In view of reports of health problems induced by low frequency (50-60 Hz) electromagnetic fields (EMF), we carried out a study in 18 healthy subjects, comparing sleep with and without exposure to a 50 Hz/1 mu Tesla electrical field. We found that the EMF condition was associated with reduced: total sleep time (TST), sleep efficiency, stages 3 4 slow wave sleep (SWS), and slow wave activity (SWA). Circulating melatonin, growth hormone, prolactin, testosterone or cortisol were not affected. The results suggest that commonly occurring low frequency electromagnetic fields may interfere with sleep.

The paper does show (Table 2) a reduction in Melatonin, a increase in Cortisol, an alteration in the time of the GH peak from 0230 forward to 2400 and a reduction in SWS (slow wave sleep) of 15 % (97 > 82 minutes, Table 1)
========================
Good Health & Long Life,
