How to Take a Nap

Whether you think you need daytime rest or not, picking up a nap habit is a smart, healthy move. A 2010 British study found that a mid-day nap was the best way to deal with the mid-afternoon tiredness.

And, unbelievably, a 2017 study showed that people who napped regularly had a 37 percent reduced risk of dying from heart disease compared to people who didn’t nap. To get the most out of your rest, follow these tips.

How long to sleep: Naps provide a lot of help depending on how long they are, says MentalFloss.com. A 20-minute nap will improve alertness(机敏); a 90-minute nap can strengthen creativity. So have a nap between 20 to 90 minutes. If you wake up from a nap feeling confused or more tired, it’s likely that your timing was just off.

What time to sleep: Prevention. com says that you experience a natural drop in body temperature between 1 pm and 3 pm. A power nap at this time can improve alertness for several hours and, for most people, won’t affect being able to fall asleep at night.

How to get comfortable: MentalFloss. com says it takes about 50 percent longer to fall asleep sitting up than lying down. (That’s why we sleep so poorly on planes and trains!) Pick a dark, quiet place . Surprisingly, the best place to sleep may be a hammock (吊床) if you have one.

Consider a “caffeine nap”: It sounds strange, but drinking coffee right before a nap may be very helpful for your alertness after the nap. Since caffeine takes 20 to 30 minutes to take full effect, you’ll feel even more awake after your 20-minute nap.
