In the afternoon, many people see a normal dip in vigilance, mostly between 1 pm and 4 pm. Although some believe that this is due to a heavy lunch, experts suggest that the body naturally goes through a cycle of waking up and fatigue throughout the day.

The body’s clock usually experiences fatigue time during the afternoon. Studies show that to combat this period, a small nap not only enhances vigilance, it also improves cognitive function.

This “power nap” helps the brain to relax without slipping into deep sleep.

But there is a catch: a very long naping can result in wake up in waking up than before. The duration of these naps plays an important role in determining their benefits and potential shortcomings.

The nap of the afternoon can lead to energy and focus, but if it is too long, it can do more harm than well. Sleeping for more than 30 minutes can lead to “inertia of sleep”, after waking up from deep sleep, he may feel heavy, disgusting.

This may make you feel more tired and confused than before, especially if you need to do something important.

Once a nap is more than half an hour, your brain enters deep sleep.

Waking up during this phase can make you feel dull for an hour. In addition, it can be difficult to sleep at night with too late during the day.

Research supports the benefits of short nap. NASA found that a 26 -minute nap improved the vigilance of up to 54% in flight employees and increased the performance by 34%.

Athletes often nap to fix their muscles and help improve response time and stamina.

People in high stressed jobs like doctors and pilots also use small naps to stay faster and avoid mistakes.

Experts say that the best nap for 10 to 20 minutes should be from 2 pm and before 2 pm. A cool, dark and cool place is ideal. If this is not possible, the eye mask and noise-making headphones can help.

But napping is not for everyone, according to Talor Maukterian, a professor in mental health, Warwick Medical School, Warwick University, who wrote in the conversation.

Your age, daily routine, and sleep habits all affect how a nap works for you. A well -time nap can be a great tool, but can mess up your night’s sleep at a bad time. The researcher said that the key is to try and see the best work for your body.
