2. Using Mobile Devices
You may think that checking your phone or reading a book on your tablet will help you fall asleep, but the opposite is actually true. These devices emit what is called blue light, which stimulates the brain into activity by suppressing melatonin. This is the brain chemical that is responsible for helping you fall asleep at night.
To solve this problem, keep your devices and chargers in a separate room altogether so that you’re not tempted to check your email or watch a quick video to help you sleep. Turn your devices off at least an hour before bedtime so that your brain has some time to wind down. Alternatively, if you can’t kick the habit, see if your phone has an option to reduce the amount of blue light on the screen so that you can fall asleep more quickly.
