It can be tempting to take a nap in the middle of the day.
Dr. Rebecca Robbins, a sleep expert, says data shows that napping can be good for you; but it shouldn’t be a substitute for a full night’s sleep.
Robbins also says that the perfect nap is ten to 20 minutes long, the ideal time to nap is between 2 p.m. and 4 p.m.
You should not nap if you suffer from insomnia. And you’ll get the highest benefits from napping if you do so at the same time each day – you’ll even learn to fall asleep more quickly, and to wake up without an alarm.
