Many people don’t like taking naps, especially young people nowadays. They are used to irregular lifestyles, so they have probably forgotten about taking naps long ago. In fact, there are many benefits of taking a nap, but some people are not very clear about the concept of nap time, and sometimes they sleep for the whole afternoon, which does not bring any benefits. Therefore, you should also grasp the measurement of time for nap. Here is an introduction to the length of nap time. The nap time should not be too long, about 10-30 minutes is appropriate. Research suggests that human sleep is divided into two stages: light sleep and deep sleep, which alternate in a cyclical cycle. Generally, people will enter the deep sleep stage from light sleep after falling asleep for more than 30 minutes. At this time, the inhibition process of various central nervous systems in the brain deepens, many capillaries in the brain tissue are temporarily closed, the blood flow through the brain tissue is relatively reduced, and the metabolic process in the body gradually decreases. If you wake up at this time, you will feel uncomfortable all over and more sleepy. This is because the suppressed cerebral cortex has not yet been released, and the closed capillaries have not yet opened, resulting in a temporary relative lack of blood supply to the brain, causing temporary autonomic nervous dysfunction. This symptom can last as short as ten minutes or as long as more than half an hour to disappear. This symptom is the biggest disadvantage of taking a nap in bed. Because when taking a nap in bed, most people will inevitably enter a deep sleep, resulting in the nap being too long. In this way, after getting up, you will feel uncomfortable all over, dizzy and unable to concentrate on work or study for a long time, which will affect your work and study efficiency in the afternoon. Moreover, it often takes a long time to fall asleep after a nap, which invisibly increases the anxiety in your heart. What's worse, because the nap at noon is too long, people can't fall asleep at night, which may lead to insomnia in severe cases. This will affect the work and study efficiency of the next day. Over time, it will form a vicious circle and disrupt the normal biological rhythm of the human body. The benefits of a nap are not only that it allows a tired body to rest, but also that it keeps people energetic throughout the day. Generally, as long as you insist on taking a nap for about 30 minutes every day, your body's functions will be greatly improved. Take advantage of this opportunity! |
