The designers of our smartphones, tablets, and laptop screens have been able to create incredibly powerful lights. These screens glow bright enough to be seen during a sunny day. At night, they’re so strong that they’ve been compared to a “little window” that daylight can peer through.
That’s why looking at your phone at night is a terrible idea.
Our bodies naturally follow a cycle that allows us to stay awake and alert during the day and helps us get essential rest at night. But when we look at these screens as we’re getting ready to sleep, our brains get confused. Bright light can make the brain think it’s time to stop producing melatonin, a hormone that gives your body “time to sleep” cues.
By disrupting melatonin production, smartphone light can disrupt your sleep cycle, almost like an artificially induced jet lag. That makes it harder to fall and stay asleep — which could lead to serious health problems.
