New Zealand, Norfolk Island, and OuvÃ©a, the Polynesian outlier near New Caledonia, are the unsubmerged portions of the largely sunken continent of Zealandia.
The 20-minute power nap -- sometimes called the stage 2 nap -- is good for alertness and motor learning skills like typing and playing the piano. What happens if you nap for more than 20 minutes? Research shows longer naps help boost memory and enhance creativity.
Studies have shown that the optimal nap time is ~12 minutes. A little more doesnât bring much additional benefit, and too much more leaves you in the groggy/need too much recovery part of the cycle. And anything less than 10 minutes doesnât give much benefit. The main thing is to make sure not to be less than 10 and more than 25 minutes.
