Watch: How Long To Nap For, According To Science

On the days when you just didn't get the sleep you needed the night before (and an extra cup of your favourite Toffee Nut Latte just won't cut it), you may need something a little stronger to get you through the day (sadly no, we don't mean a glass of wine at 2pm).

Often, the key to feeling re-energised is to get an extra 40 winks, ? la a daytime or early evening nap. A new video from AsapSCIENCE claims that you can, in fact, take a nap that doesn't leave you feeling more drained than you did before you put your head down. And therein lies the science behind it all: The length of your snooze is key to how restored you'll feel once woken.

Naps can get a bad rap because too often, people sleep for longer than 30 minutes - long enough to fall into stage three or four of their sleep cycle (the deepest stages), and end up with sleep inertia. Instead of waking up refreshed, you just feel groggy and want more slumber. If done correctly, a power nap is an extremely effective method to rejuvenate yourself during the middle of a working day.

And a quick nap might benefit more than just your energy levels; research has found that nappers who slept until they reached stage two (light) sleep saw increased productivity, memory, and creativity, amongst other positive effects. Thank you science, for giving us another reason to indulge in some extra shut-eye.


Now all we need is to make certified nap times a regular work occurrence, and we'll be sorted.
