Curb the caffeine: Skipping the double espresso after dinner might be a no-brainer. But if you’re particularly sensitive to caffeine’s stimulating effects, you ought to make the switch to decaf during the afternoon—by 2 p.m. Remember that you can get a caffeine buzz from soft drinks, energy drinks and chocolate—not just coffee. Some medications contain the stimulant too.
Take a tech time-out: Light emanating from your smartphone, television or computer monitor can suppress your body’s secretion of melatonin, making it harder for you to fall asleep. Instead, wind down by listening to soothing music or doing gentle yoga for 15 minutes.
