Fed up with feeling tired but wired at night? If you want to properly unwind before bed, it’s worth keeping devices away from the bedroom or stop using them an hour or two before bed. Too much exposure to the blue light that many screens emit can interfere with the production of melatonin, which can lead to that feeling of your mind being awake when your body needs to rest.

Try leaving your phone outside the bedroom at night or, if that’s too big a step, limit usage before bedtime and switch it to night mode, which dials down the blue in favor of warmer tones.
