Melatonin: A New Way to Diagnose Electrohypersensitivity

It has been shown that absorption of electromagnetic fields (EMF) at the level of the head occurs mainly through the eyes (1)(2), following the same path as light from the retina to the pineal gland where melatonin is secreted (3).
Melatonin levels, as measured in the 24h urinary excretion of its main metabolite p-hydroxysulfate (6-OHMS), are significantly lowered in 88% of cases (4) from several hundred people clinically categorized as sensitive to EMF or electrohypersensitive (EHS) (5).
By contrast, melatonin values are not altered in normal individuals exposed to EMF (6), while no abnormalities in the mean amount of daily melatonin excretion have been reported in depressed patients (7).
Melatonin depletion measured in people suspected of being electrohypersensitive could thus be specific for such population of patients and contribute to an objective diagnosis of their pathophysiological deficiency.
Since melatonin inhibits matrix metalloproteinases that control the blood-brain barrier (8)(9) a reduced secretion will favor its opening. The resulting hypoxia would explain the disorders (10) in the cerebral sphere of EHS subjects.
In these people, a sleep deficit is predominantly observed.
Treatment by melatonin is therefore indicated for the test-related responding person whose resulting improvement of symptoms would bring a piece of confirmation that electrohypersensitivity was correctly diagnosed.
