Effect of Light Exposure Before Bedtime on Polysomnography and Sleep Quality: A Randomized Crossover Study
A 5000k LED light leads to longer sleep latency compared to a 5000k fluorescent light. Restriction of electronic device use before bedtime improves sleep onset in healthy adults. Managing ambient light exposure with lower color temperature LED light and reducing electronic device use 2 hr before bedtime may improve sleep quality in healthy adults.
