Summary:

This animal study looked into the effects of ELF MF exposure on the melatonin levels in calves. Eight young calves were divided into two groups: control and exposed group. The experiment was done twice, one in summer and one in winter. For each experiment, four calves were exposed to ELF MF at the intensity of 0.39 – 0.41 microtesla (µT) which is around 250 times below the current international guidelines for public exposure (which is 200 µT), for 35 days, and saliva samples were taken regularly. It was found that in the exposed group the melatonin level was reduced in winter and increased in summer. The authors hypothesised that the ELF MF exposure may have a different effect on the melatonin level depending on the season.
