Disturbed sleep in individuals with Idiopathic environmental intolerance attributed to electromagnetic fields (IEI‐EMF): Melatonin assessment as a biological marker

In this study, we compared levels of melatonin between a sensitive group (IEI‐EMF, n = 30) and a non‐sensitive control group (non IEI‐EMF, n = 25) without exposure to electromagnetic sources. Three questionnaires were used to evaluate the subjective quality and sleep quantity: the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index and the Spiegel Sleep Inventory. Melatonin was quantified in saliva and its major metabolite 6‐sulfatoxymelatonin (aMT6s) in urine. Melatonin levels were compared by a two‐way analysis of variance at various times between the control and IEI‐EMF group. Despite significantly different sleep scores between the two groups, with a lower score in the IEI‐EMF group (P < 0.001), no statistical difference was found between the two groups for saliva melatonin (P > 0.05) and urine aMT6s (P > 0.05).
