Investigating the Efficacy of an EMF Blocking Blanket on Sleep Quality

Abstract

Sleep Quality may be affected negatively by con-

tinuous electromagnetic fields (EMF) exposure from telecom-

munication devices, which may further lead to mental health

disorders such as anxiety and depression. There are multiple

products that claim to block EMF exposure and improve sleep

quality. The objective of this study was to have an unbiased

quantitative investigation of the efficacy of one such product

called “SleepGift” blanket, on sleep quality. A single-blind

cross-over study was conducted and the sleep study data of 16

healthy participants, who finished the study, was analyzed.

Each participant used real and sham SleepGift blankets for two

10-day study blocks, separated by 30 days of washout period.

Sleep data were recorded at pre- and post-intervention of each

real and sham block. Sleep quality was assessed using the Odds

Ratio Product (ORP) and sleep architecture, along with Elec-

troencephalography (EEG) metrics such as delta power, delta

durations and spindles. The results show no significant changes

in any of the measured parameters due to using SleepGift real

blanket. Given the small samples of this study, a larger data set

is recommended to achieve robust conclusion about the efficacy

of SleepGift blanket.
