3.Surf the Web
Artificial light at night can be bad for sleep. But the “blue light” on smartphones and computers is particularly bad — televisions, too. Shut down bright screens 2 to 3 hours before bedtime to get your body ready for snoozing.
4.Take a Nap
It’s a great way to catch up on a little shut-eye. But if you take one after 3 p.m., it might affect you later on. So, no naps and no coffee. A splash of cold water on your face or a brisk walk can get you moving again.
