9.Do: Eat Light and Early
If you don’t want to repeat last night’s lack of sleep, a big greasy burger, fries, and a shake at 11 p.m. probably won’t help. Eat a lighter dinner several hours before bed. If you’re hungry later, snack lightly on foods that don’t disturb your sleep. Toast or yogurt are often easy on the system.
10.Don’t: Surf the Internet
Too much of any light after the sun goes down can mess up your sleep, but the “blue light” given off by your smartphone, computer, or tablet is especially bad. Calm yourself before bed. Keep your bedroom dark and quiet, too.
