Does being on the computer too much cause sleep prevention?

Using electronic devices such as computers, smartphones, or tablets before bedtime can indeed affect sleep. The blue light emitted from these devices can interfere with the production of melatonin, a hormone that regulates sleep-wake cycles. Melatonin helps the body prepare for sleep by lowering body temperature and decreasing alertness. Exposure to blue light suppresses melatonin production, making it harder to fall asleep and disrupting the quality of sleep.

Several studies have found a link between screen time before bed and sleep problems. For instance, a study conducted by the National Sleep Foundation in the US showed that individuals who used electronic devices within an hour before bedtime took longer to fall asleep, had reduced sleep efficiency (the percentage of time spent asleep during the total time spent in bed), and experienced more daytime sleepiness.

To minimize the impact of screen time on sleep, it is recommended to avoid using electronic devices for at least 30 minutes to an hour before bedtime. Dimming the screen brightness and using blue light-blocking glasses can also help reduce the disruptive effects of blue light. Additionally, creating a relaxing bedtime routine and ensuring a comfortable sleep environment can further promote better sleep.
