Brief Summary

The goal of this study is to see the effect that a cooling pillow pad called Moona has on sleep quality.

Detailed Description

Obesity and diabetes pose a significant burden on healthcare systems worldwide. Evidence from large cross-sectional and longitudinal epidemiologic studies, and well-designed experimental sleep manipulations, demonstrated that insufficient sleep is a risk factor for obesity-induced insulin resistance and type 2 diabetes. Limited available evidence suggests that optimizing sleep duration and quality in individuals who experience deficient sleep could have beneficial effects on weight maintenance, facilitate weight loss and improve glucose metabolism. It is well known that body temperature impacts sleep. A rapid decline in core body temperature increases the likelihood of sleep initiation and may facilitate an entry into the deeper stages of sleep.

Pharmacological treatment is often prescribed for sleep disturbances, primarily insomnia. But sleep extension with benzodiazepines/sedative-hypnotic agents does not appear to have beneficial effects on metabolism, in fact, these drugs may even have an adverse effect on glucose metabolism. Many people use melatonin as a sleep aid, however, the available data do not support a major role of melatonin in body weight regulation and the evidence supporting melatonin administration in improving glucose metabolism has been mixed.

Limited studies suggest that localized cooling could represent a non-pharmacological strategy to favor sleep onset or improve sleep duration and/or quality.

Primary Outcome Measures
NameTimeMethod
Sleep Outcome- Sleep durationBaseline to Day 22

Change in Sleep duration from baseline to day 22 measured in minutes by Wrist Actigraphy Monitoring.

Change in Sleep duration from baseline to day 22Baseline to Day 22

Sleep duration measured in minutes by polysomnography.

Sleep Outcome-Time to sleep onsetBaseline to Day 22

A decrease in time to sleep onset from baseline to day 22 measured in time of day by Wrist Actigraphy Monitoring.

Sleep Outcome- Regularity of sleepBaseline to Day 22

Change in regularity of sleep from baseline to day 22 measured by Wrist Actigraphy Monitoring. The value is from standard deviation of time of middle of the sleep period.

Sleep Outcome- Wake timeBaseline to Day 22

Change in wake time from baseline to day 22 measured in time of day by Wrist Actigraphy Monitoring.

Change in glucose homeostasis after 22 days of Moona Device usage.through study completion, an average of 1 month

The Matsuda Index of whole body insulin sensitivity, the homeostasis model assessment (HOMA) measures beta cell function and insulin resistance. These changes in glucose homeostasis from baseline to 22 days of Moona Device usage are measured by Oral glucose tolerance test (OGTT).

Sleep Outcome- Sleep microarousalsBaseline to Day 22

Change in wake time from baseline to day 22 measured by polysomnography. The index is generated by polysomnography software.

Sleep Outcome- Sleep efficiencyBaseline to Day 22

Change in sleep efficiency from baseline to day 22 measure by a percentage of total sleep time/time in bed from Wrist Actigraphy Monitoring.

Change in sleep efficiency from baseline to day 22Baseline to Day 22

Sleep efficiency measure by a percentage of total sleep time/time in bed from polysomnography.

Secondary Outcome Measures

Changes from baseline through day 22 of novel Patient Reported Outcome instrumentBaseline to Day 22

Detection of within-patient changes in sleep effects reported in a novel Patient-Reported Outcome instrument between baseline and Day 22.

Pre-sleep and durational sleep secretion of melatonin values at days 7-8 and days 21-22.through study completion, an average of 1 month

Urine samples will be collected at two timepoints before bedtime and in the morning. The secretion of melatonin at these timepoints will result in a numerical value.
