LED screens, which includes cell phones, tablets, TVs and other gadgets, give off blue light; a type that studies have suggested to impede the production of the sleep-inducing hormone melatonin and disrupt our circadian rhythms.

It is, therefore, advisable to shut down all electronics two hours before bedtime. And if possible, keep phones and laptops in another room while you sleep.
