As electronics have invaded our lives, they created an easy means to build and communicate through social networks and they can provide non-stop entertainment or stimulus for our brains. However, the brain have not evolved at as fast a clip and cannot handle all the screen time we give it.

Too much screen time makes it difficult for our brains to calm down and let us sleep. Not only are we sleeping less, the quality of our sleep is declining. We are all more tired and less effective and productive during our awake time. So perhaps it only makes sense that to improve our sleep quality, we limit our time with our electronics.

One of the reasons our electronics impact our sleep is that they bombards us with blue light. “Blue light” is what it sounds like: blue light wavelengths. They are important for us when we’re awake because they boost attention and reaction times. However, when we’re bombarded with blue light at a time of day when we do not need those boosts, they can be disruptive by encouraging our brains to stay awake.

Aside from the blue light, think about all the adrenaline that gets released in your body when you receive alerts or notifications from your phone or when you’re watching the news before bed. That rush, even if it’s small, will make it difficult to go to sleep.
