Official title

Effects of Sleeping With Dim Light at Night in Patients With Obstructive Sleep Apnea

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

With the advent of electricity, light at night has become a ubiquitous part of our society. The main purpose of this study is to determine whether sleeping with dim light (40 lux), the brightness of a night light) in your bedroom for 5 consecutive nights will result in increased markers of inflammation in the blood compared to sleeping in darkness during the night in patients with obstructive sleep apnea (OSA). A secondary aim is to examine the effects on insulin sensitivity, other blood proteins, and RNA molecules as a result of sleeping with dim light. RNA molecules are substances in blood that dictate what type of proteins the body should make.
