When it comes to napping, you can't just close your eyes and hope for the best. You have to think it out.
Napping is associated with numerous health benefits, including a lower risk of death from heart disease, lower blood pressure, and various psychological benefits. It can also be a boom for productivity, such as increased alertness and better concentration.
However, not all naps are created equal.
A 20 to 30 minute nap is considered the optimal nap time because you enter the much coveted stage 2 sleep, which enhances alertness and concentration, and improves motor skills. Most importantly, you don't enter deep sleep and therefore won't wake up groggy and unproductive.
