Nap of Choice

 

The Nothing-Nap: This nap lasts a whopping 10 to 90 seconds. Studies are inconclusive as to the benefits of nodding off on someone’s shoulder while on the bus (13).

The Quickie Nap: 5 to 20 minutes of shut-eye can increase alertness and motor performance (14,15).

The 20 Minute Snoozer:: This also allows for an increase in mental alertness and the increased performance of tasks (16).

The Deluxe Nap:If you can afford the time a 50 to 90 minute nap allows for muscle recovery to take place. This nap includes slow-wave plus REM sleep; which is when growth hormone is released.

The Caffeine Nap: Drink your favourite Starbucks caffeinated beverage and immediately take a 15-minute nap. Coffee helps clear your system of adenosine, a chemical which makes you sleepy. A combination of a cup of coffee with an immediate nap chaser provided the most alertness for the longest period of time (17).

Note: One of the side effects of snoozing occurs upon awakening. The feeling of grogginess that is often experienced here is called Sleep Inertia. Minimizing the time it takes your brain to get into sync can be accomplished by not waking up while you are in the Slow Wave Sleep stage.

If you don’t want your naps to interfere with your night-time sleep keep them under the 3 hour mark and make sure they are completed at least 3-4 hours before going to bed (18).

 

Conclusion

Taking a power nap provides more patience, less stress, increased learning, better health, better reaction time, more efficiency. Many athletes, moreover, find a daytime nap further increases their body's ability to build muscle. Dr. Sara Mednick, a scientist at the Salk Institute for Biologicak Studies adds that “Napping also benefits heart functioning, hormonal maintenance, and cell repair.”

So stop feeling guilty and take a well-deserved nap at work or at home. Your Nattitude (nat´y-tood´)n.: a proud attitude about one's napping) should be displayed by laying your head down and grabbing some well-deserved shut-eye. Now, if you’ll excuse me, it’s past my naptime, and I’ve got to get set-up for the rest of the day.
