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.
Limit naps to 20 minutes (see my last tip for an alternative). Napping for longer than 20 minutes can allow the person to enter deep sleep and to then wake up from deep sleep. Sleep inertia lasts longer and the effects are worse when you wake up from deep sleep. Avoid napping between 22:30 and 04:40 hrs.
