Take a power nap – but not too late in the afternoon.

A short power nap can have a temporarily invigorating effect, but avoid sleeping longer than half an hour or too late in the afternoon as it can make it harder to fall asleep at night. Yoga and meditation can be other ways to achieve similar effects as a shorter period of sleep.

WHY IT HELPS:
A power nap or meditation can reduce your feeling of sleepiness and increase your focus, without disturbing your circadian rhythm. Normally, the effect of a nap lasts for about two hours, resulting in improved mood, focus, and cognitive ability.
