The two biggest problems with falling asleep in front of a screen are the same as falling asleep in front of a TV. Whether you are scrolling news feeds or watching TikTok videos, you are not going to end up sleeping as much.
Blue light and melatonin are related. Even though the dangers of blue light are overblown, any light in your eyes before bed is not helping you sleep. Light exposure can interfere with melatonin production in our bodies. A lit-up screen is still a lit-up screen, even with blue-blocking glasses, screen coating, and night modes.
The other reason is that if your TV show is long, your brain will be too busy to relax and sleep. Anyone who has stayed up until 3 a.m. is aware of this phenomenon. If the show is boring, you're probably going to sleep faster.
Those are the bad things. There are a lot of pros. Listening to something as you drift off to sleep can help block out mental distraction. White noise is a sleep aid. White noise is not the soundtrack to your dreams; any subtle, comforting sound can do the job.
Research shows that watching a familiar TV show can help us deal with stress and get back to feeling in control of our lives. It can be helpful if your mind is racing and you are too anxious to sleep.
It's not a bad thing to fall asleep to the TV. Ask yourself if it is helping you fall asleep. Consider facing away from the screen, putting on a familiar but boring show, and using the sleep timer to make sure you don't wake up to commercials in the middle of the night.
