In summer, when the weather is hot and you are healthy in the summer, you must first sleep well, especially a nap. A short nap can make you feel good in the afternoon and throughout the night. However, many people do not pay attention to the siesta problem. How to get a nap before it is healthy? How long is it appropriate to nap? Let's look at it together.
More naps are needed in summer
Did you find that "Every summer is easy to make you sleepy?" Summer "difficulty" is due to short summer days, hot summer nights and unbearable heat, affecting the quality of sleep. The high temperature causes the blood vessels of the human skin to expand and the blood flow in. These are all The consumption of the body can be increased, and the feeling of fatigue appears to produce drowsiness. In addition, due to work or lifestyle reasons, many people lack regular patterns of daily life, often stay up late, and lack of sleep.
How long is it appropriate to take a nap?
A healthy siesta takes 15 to 30 minutes to be most appropriate. If it is more than 30 minutes, the body will enter a deep sleep period that is not easy to wake up. It may be better to extend it to 1 to 1.5 hours to complete a whole sleep cycle. For a long time in nap, there will be a slight headache and general weakness in the first half hour. This is caused by "sleep inertia." Don't expect to wake up immediately at this time, and it will return to normal after an hour of buffering. However, this longer nap is only suitable for supplementing the lack of sleep on the previous night. A truly healthy nap should not exceed 30 minutes, otherwise it would easily disturb the physiological clock and affect normal sleep.
After nap, light activity after waking up
After waking lightly, you should stand up slowly after nap and drink a glass of water to supplement blood volume and dilute the blood viscosity. Do not immediately engage in complicated and dangerous work.
