Is it necessary to take a nap in winter?

Napping can not only relieve tension, delay aging, but also reduce myocardial infarction.

First, taking a nap is not a sign of laziness, nor is it necessarily related to abundant food. Studies on sleep show that people tend to fall into a semi-sleep state in the first few hours of the afternoon.

Second, after a nap, the brain is better used, more flexible, more responsive, more energetic and more emotional.

Third, turn a nap into a habit. But for people who don't take a nap every day, it is not advisable to take a nap because it will affect their sleep at night.

4. Taking a nap is a way to relieve tension, which effectively helps people to maintain psychological stability, especially for people who are nervous at work every day. According to Dr Cartier's theory, daily activities can make people secrete oxides that lead to cell aging. Therefore, people can get better maintenance and relax their nervous mood during the nap.

According to a recent survey, taking a nap for half an hour every day can reduce the possibility of heart disease by 30%, because at rest, heart consumption and arterial pressure are reduced.

Sixth, taking a long nap will be counterproductive. In order to make a nap beneficial to human body without affecting sleep at night, it is advisable to take a nap for 30 to 60 minutes. However, for those who often suffer from insomnia, taking a nap is not advisable. Because I can't sleep at night after taking a nap.

According to Professor Chiofalo's theory, there are two kinds of people who need to take a nap, one is those who sleep at night, and the other is those who go to bed early and get up early. Napping is a scientific regulation of human biological clock, but there are also taboos:

1. Try to avoid taking a nap. It is best to control the nap time within half an hour, otherwise it will be very uncomfortable to wake up. If this happens, get up and exercise properly, or wash your face with cold water, the discomfort will soon disappear.

2. Avoid taking a nap at will. You can't just lie down and sleep in the corridor, under the shade, on the grass, on the concrete floor, and don't take a nap in the draught or on the tuyere. Because people's body temperature regulation center function declines during sleep, people who wake up are unwell, and those who are serious will catch cold and get sick.

3. Avoid sleeping naked. No matter how hot the weather is, cover your abdomen with a towel or quilt during a nap to prevent the cold from taking advantage of it.

4. Avoid intermittent naps. The habit of taking a nap should be persistent, because taking an irregular nap will also disrupt the physiological clock and affect the law of sleeping late.
