Feel ENERGIZED and REFRESHED with a Power Nap! Nap Timer allows you to fall asleep and wake up within a period of time. SCIENTIFICALLY PROVEN cientifically proven to improve cognitive function, increase productivity, and alertness while leaving you energized and refreshed. Nap Timer is the SIMPLE and FAST way to set an alarm for the ideal power nap. A study by NASA found a 26-minute power nap improved performance by 34% and alertness by 54%. The secret to successful power naps is not sleeping too much. It is advised not to sleep over 30 to 40 minutes, which at this point you enter a state of deep sleep. Waking up in deep sleep causes sleep inertia, leaving you feeling groggy, drowsy, and generally worse off than before the nap. Power Nap Timer prevents you from entering this state of sleep by limiting how many minutes you are allowed to set an alarm to wake up from your nap. 6 Benefits of Power Napping: 1. Reduces Stress 2.
