Many people have the habit of taking a nap. This short nap has many benefits for many people, according to the health website Healthline (USA).

A nap lasting 30 minutes or more can make us feel tired and lack of alertness after waking up. Because when napping for more than 30 minutes, the body will switch to a deep sleep stage. This sleep stage not only makes it difficult to wake up but also makes the body feel lethargic and lack of energy.

Therefore, whether it is at noon or in the afternoon, or after work, you should not sleep for more than 30 minutes.

If you sleep for 20 to 30 minutes, your body will receive many benefits. When you wake up, you will not only not feel tired but also more alert and healthy. This sleep then plays a role in helping to restore energy, work and exercise more effectively.

To avoid sleeping too long, people should set their alarm clock for about 30 minutes. The ideal sleeping space is a place that is slightly dark, quiet, cool and comfortable.

The ideal time to take this nap is between 1pm and 4pm. Sleeping during this time frame will cause less disruption to your circadian rhythm and will not affect your sleep at night.

Another way to help you feel more alert after waking up is to drink some coffee before going to bed. Caffeine usually takes about 15 minutes to metabolize and take effect in the body. Therefore, after a short 30-minute nap, the drinker will feel alert when waking up. Not only that, the caffeine in coffee also has the effect of increasing work and exercise performance, according to Healthline .
