Text 1
Taking a nap is frowned upon by many people and is viewed as fondness for the elderly and children. Mention nap and you could be seen as lazy, depressed and unwilling to work. However,
taking a nap is one of the best but most underused tools for busy people to ease weariness. The ma-jority of people experience drowsiness in the afternoon and notice their work efficiency and mood starting to slip and taking a nap will help combat this.
The results of research suggest that taking a nap can make you more alert, reduce stress and improve cognitive function compared to those who working all day without rest. A mid-afternoon
nap means that productivity can last long into the night. Researchers at NASA found that a 30- minute full nap increased cognitive function by 400/o . The volunteers on the tests found that their memory improved as well as experiencing an increase in concentration. Those who didn't nap would score lower on IQ test than those who did (after a day of work).
If you feel tired in the afternoon and from then on can't perform. at your best, I recommend taking a short power nap to get yourself feel alert and ready for' work. You will notice your mood and alertness to be improved. I advise keeping the nap between 15 and 30 minutes if you want to avoid getting into deeper stages of sleep. If you do, you'll find it harder to wake and may
experience the unstable feeling for a while.
For those who are worried about the after-affect of a nap, there is the caffeine nap. A caffeine nap is taken after an intake of caffeine, so that you are asleep while your body digests the caffeine. After a 15 - 30 minutes nap, you wake up and have the caffeine in your system. This is great if you need to be instantly on the move after a nap, and you can bounce out of your sleeping state and jump into refreshed work feeling.
Finding 15 -30 minutes to take a nap in a day sometimes seems difficult, but doing so is very helpful to your productivity. Even 10 minutes of a nap every day will be better than nothing at all, and may give you the energy you need to be successful. If you're willing to have a try, make sure you can find a comfortable place before setting your head down. If you can feel secure and let go,
then your rest will be even more beneficial.
