ID Number		2008
Study Type		Human / Provocation
Model		16 Hz (ELF) exposure to human volunteers and analysis of circulating melatonin levels as well as core temperature and heart rate
Details		Volunteers (n = 7 males) were exposed to 50 Hz (ELF at 16.7 Hz, 0.2 milliT), visible light (1500 lux), or infrared radiation (to 65°C) and analyzed for core temperature, heart rate, and salivary melatonin levels. Melatonin synthesis was transiently suppressed by light and the nadir of temperature and heart rate was delayed during nighttime. Infrared radiation elevated core temperature and heart rate. Magnetic field exposure had no effect.
Findings		No Effects
