Investigating the Efficacy of Sleepgift Blanket on Sleep Quality and Heart Health

Early Phase 1

Completed

• Conditions: Sleep
• Interventions: Device: Active sleepgift blanket; Device: Sham Sleepgift Blanket

• Registration Number: NCT05463302
• Lead Sponsor: University of Manitoba

Brief Summary

Exposure to electromagnetic field (EMF) emitted by mobile phones and devices with WIFI is on the rise and so is the EMF effects on sleep quality and well-being of individuals with high exposures to EMF. Some studies have shown poor sleep quality among individuals with long-term occupational exposure to EMF, and some have shown association between EMF long-term exposure and neuropsychiatric disorders including depression. This study aims to investigate a commercially available EMF- blocker blanket, called Sleepgift, that claims helping people to have a better sleep and improved health. We will investigate the Sleepgift efficacy on adults' quality of sleep and their vital signals as a measure of their well-being in a placebo-controlled single- blind cross-over designed study. Participants will sleep in our sleep lab at baseline and then 10 days later with the Sleepgift blanket after using it every night for the past 10 consecutive days. Participants will be given two blankets for each cycle of the study as it is a cross-over designed study: one Sleepgift and one regular blanket; they will not know which one is real or sham. There will be one-month washout period between the two cycles of the cross-over study. We aim to enroll 30 adults for the study. Participants' sleep quality will be measured by the established device called Prodogy; their vital signals will also be measured and monitored through the night. The collected data will be analyzed statistically for any significant effect of the Sleepgift blanket on sleep quality and vital signals such as heart's rhythm and heart rate variability.

Primary Outcome Measures

Name	Time	Method
Sleep quality measure	Through study completion, 2 years approximately	The change in the value of Odds of the Product (ORP) from baseline line to post-intervention, measured by the Prodigy device which is a combination of the EEG band waves. ORP is only one value output of the device.

Secondary Outcome Measures

Name	Time	Method
heart rate variability	Through study completion, 2 years approximately	the change in heart rate variability (HRV) measured from beat to beat R-R interval.
