A power nap a couple times a day works wonders for the body and the mind.
Naps give you a break. While napping, your mind can go blank. Take a break. Have a rest.
When you nap, your brain can regenerate, file away information, built links between the thoughts you’ve had. Make some sort of order and sense of it all.
A nap allows your body also to rest. If you work a highly physical job, the muscles will love you for it. If you work a stressful job, a nap is the ideal way to relieve the stress. Yes, mental stress leads to physical stress, and a nap releases that stress.
When you return to the land of the living, you will be more productive. Power naps are a productivity tool! Just be careful not to fall asleep for too long – then you might be sluggish for the rest of the day – hardly productive at all.
