How to take a power nap

If you've been having insufficient sleep for a few days, you might be starting to feel its debilitating effects. When you desperately need to re-energize yourself, taking a power nap might be a good idea.

A power nap is a short nap that spans from 20 to 30 minutes. It can be used in addition to normal sleep to improve alertness, or to recover from the lack of sleep. As the nap is short, one does not feel the usual lethargy caused by sleep inertia after waking up. A power nap is an efficient way to get some rest and can even be used in a busy workplace during a lunch break.

Power naps give you many of the benefits of normal sleep while only taking a fraction of the time needed.

How to take a power nap:

1. An hour before you nap, do not take caffeine and avoid heavy meals.
2. Find a good, warm, quiet spot where you won't be disturbed for half an hour.
3. Get a chair or something comfortable for you to rest on.
4. Set your alarm to go off in 20 to 30 minutes.
   
5. If you have eyeshades, use them as darkness can help you fall asleep faster.
6. Shut your eyes and try to relax. Hopefully you'll be able to fall asleep.

If the environment is too noisy, consider earplugs or use music to drown out the noise.

In conclusion, a power nap can be useful in helping you get more sleep and rejuvenate your body if conditions permit.
