Is sleeping with the Lights On Good or Bad for You?

The Healthline article discusses the impact of sleeping with lights on, highlighting that exposure to light during sleep can disrupt the production of melatonin, a hormone that regulates sleep-wake cycles. This disruption may lead to difficulties in achieving deep, restorative sleep stages, resulting in daytime fatigue and impaired cognitive functions such as memory and concentration. To promote better sleep quality and support brain health, the article recommends creating a dark sleeping environment by turning off lights, using blackout curtains, and minimizing exposure to screens before bedtime. These suggestions are based on scientific understanding of circadian rhythms and the role of melatonin in sleep regulation, underscoring the importance of darkness for optimal sleep and cognitive performance.
