Power Nap

The power nap is thought to maximize the benefits of sleep versus time. It is used to supplement normal sleep, especially when a sleeper has accumulated a sleep deficit. The short duration of a power nap is designed to prevent nappers from sleeping so long that they enter a normal sleep cycle without being able to complete it. Power naps restore wakefulness and promote performance and learning. see link : "http://en.wikipedia.org/wiki/Power_nap" Einstein and Dali's Key Method : http://lifehacker.com/time-your-power-nap-naturally-with-einstein-and-dalis-1476441918 https://www.fastcompany.com/3023078/leadership-now/how-dali-einstein-and-aristotle-perfected-the-power-nap Power Nap is easy to use. 1- Setup maximal nap duration. 2- Put the device in your hand and start to sleep. 3- If the device fall down, you are in the deep sleep. 4- It's time to wake up.
