Late-night phone usage disrupts our sleep patterns in several ways. One major culprit is the blue light emitted by electronic screens, which suppresses the production of melatonin, the hormone responsible for regulating our sleep-wake cycle. As a result, our ability to fall asleep is delayed, and the overall duration of restful slumber is reduced. Additionally, engaging in stimulating smartphone activities like social media browsing or playing games can make it harder for our brains to wind down and relax before bed. The constant availability of notifications also contributes to sleep disruptions, as we feel compelled to check our phones even during the night, interrupting our sleep cycles.
