The potential for impact of man-made super low and extremely low frequency electromagnetic fields on sleep

Abstract

Overview

An increasing concern in health circles is the impact of man-made electromagnetic (EM) fields due to the proliferation of sources such as power lines, appliances, and telecommunication devices. This review delves into the consequences of these exposures, particularly on sleep-related aspects and melatonin secretion.

Findings

• The studies reviewed highlight that electromagnetic fields, especially from occupational and residential environments, might suppress melatonin though findings are variable and not conclusive.
• Research on the influence of radiofrequency EM fields on sleep architecture suggests minimal to no effects. Nevertheless, specific pulsating radiofrequency fields from devices like cell phones can alter brain activity.
• Such fields have shown to increase EEG power in certain frequency bands, potentially disrupting sleep when exposure occurs before or during sleep periods.

Conclusion

While initial studies present varying results, there exists a potential health concern linking EM fields to altered sleep structures and melatonin levels, emphasizing the need for further research involving a broader demographic and various EM frequencies.
