Watching TV before going to sleep isn't something that's new or different for a lot of people. And with TVs in bedrooms and streaming available on tablets and smartphones, it's perhaps not all that surprising that falling asleep while watching TV isn't all that uncommon either. There are some unexpected things that happen to your brain when you fall asleep watching TV that you might want to know more about, particularly if this is something that you do on a nightly or nearly nightly basis.
You might assume that watching TV right before shutting your eyes and falling asleep for the night isn't a good idea because it will always make sleep way worse, but the situation is a little bit more complicated than that. Though there are certainly some big things that might be a bit more negative that can happen as a result of falling asleep while watching TV, there are also some other things that might be going on here as well. Whether you always fall asleep while watching TV or it's more of just an occasional, accidental thing when you fall asleep on the couch with all of the lights as well as the TV still turned on, it's a good idea to know what might be happening in your brain and body when you do.
