Napping called can make you difficult to sleep at night. But if you do it at the right time, napping can actually restore energy and concentration throughout the day. Therefore it is one way of dealing with a tiring day.
Many studies have found that napping can improve a person’s performance, alertness, concentration, and judgment. These things are important for astronauts in space stations orbiting the Earth, so NASA is interested in researching the benefits of taking a nap.
When NASA researchers conducted a study of their astronauts, they found that a 25-minute nap could increase the scoring ability by 35 percent and vigilance by 16 percent. No wonder NASA advocated the astronauts to take a nap.
In another study, the researchers compared the difference in the benefits of taking a nap by drinking coffee. They found people who nap 15 to 20 minutes would be more alert and do better jobs in the rest of the day than those who outsmart them by drinking a large glass of coffee containing 150 milligrams of caffeine.
When we take a nap, the part of our brain that always works when we wake up, have a chance to rest. It’s like a muscle that has the chance to improve at rest. In a review of effectiveness, the researchers found that sleeping for 10 minutes was the greatest benefit, although many also called “important under 30 minutes”.
Napping longer than 30 minutes will be counterproductive because it makes us wake up feeling dizzy, lazy, and sluggish than before we sleep. This condition is called “sleep inertia” that occurs when we wake up in the middle of a deep sleep. The feeling of dizziness is the body’s natural way to get us back to sleep. Individual sleep generally does not occur in the first 30 minutes, and that’s why we are advised not to take a nap longer than 30 minutes.
In some situations, people may nap for 90 minutes to 2 hours. The old sleep will resemble a night’s sleep, which may make it difficult to sleep at night. The researchers only suggest a long nap for those who do need to sleep during the day like athletes who practice twice a day.
Therefore if you have time, take 10 to 30 minutes to take a nap. You will wake up with a sense of well and continue the day with more excitement.
