Reduce Screen Time Before Bed
Stop checking your email or watching TV just before bedtime and you'll sleep better. A recent study shows that people who consume electronic media just before bedtime report lower-quality sleep even when they get as much sleep as non-pre-bedtime screen heads. Life hacker reader JFitzpatrick says this makes perfect sense:

Using a light-emitting device before bed like a flickering TV or computer monitor stimulates the brain in a different way than the way the body was intended to move towards sleep That's why it is so easy to waste sleepless hours flipping from channel to channel. The exposure to light stimulates the brain and creates a false alertness and stimulation.

Yeah, that's true.
Let me explain more actually about watching a screen before going to bed:
Whenever your eyes see a lot of light or a blue color or a screen, they will not produce melatonin hormones. Once they see darkness, they will produce melatonin which will relax and you and make you sleep.
