A lot of people sleep with their phone right next to them and a lot of people look at their phone first thing in the morning , It could be adding to your stress level.
If you look at your smartphone first thing in the morning, it could make you feel stressed and overwhelmed. Experts say, the information overload before you are fully awake could interfere with prioritizing your tasks for the day. Which could also make you unproductive because you could be waking up to things you didn't finish the day before and trying to work around that.
I recently started to plug in my cell away from the bed, I think I like this. I'm not waking up every time the cell light turns on when I get a notification. Plus, less tempted to lean over to see what it is.
