The soft blue glow from a cell phone, tablet, or digital clock on your bedside table may hurt your sleep.
Tip: Turn off TVs, computers, and other blue-light sources an hour before you go to bed. Cover any displays you can’t shut of
You’ll rest better at night. But if you have to snooze while the sun’s up, keep it to 20 minutes or less. Nap in the early part of the day.
Tip: Overcome an afternoon energy slump with a short walk, a glass of ice water, or a phone call with a friend.
