What are the benefits of a lunch break? Do you want it in winter?

Of course, lunch break has many benefits, and it is also necessary in winter. Here are some precautions about lunch break (nap): don't fall asleep after dinner. Generally, after a nap, people will feel refreshed, so they think that as long as they have a nap, they can achieve the effect. Note: In fact, everyone knows that taking a nap in summer is very important, but the effect of taking a nap is not based on people's feelings, but depends on how and how long they sleep. The easiest time for people to fall asleep is 8 hours after getting up in the morning, or 8 hours before going to bed at night, which is about noon 1. At this time, people's alertness is in a natural decline period, and their bodies will get a good rest. The most suitable time for a healthy nap is 15 ~ 30 minutes, and the longest time should not exceed 1 hour, which is too short to meet the requirements of rest; If it takes too long, you will wake up with a slight headache and general weakness, and it is not easy to wake up at this time. It is best to extend it to 1 ~ 1.5 hours, a complete sleep cycle. In addition to paying attention to sleep time, you should also pay attention to hygiene during a nap. Don't eat too greasy things before going to bed, and don't eat too full, because greasy will increase blood viscosity and aggravate coronary artery disease, and satiety will increase the digestive burden of the stomach. In addition, many people are used to sleeping after lunch. At this time, the stomach is just full of food, and a large amount of blood flows to the stomach, blood pressure drops, and oxygen supply and nutrition to the brain drop significantly. Falling asleep immediately will cause insufficient blood supply to the brain. Therefore, it is best to do 10 minutes of activities before taking a nap, such as walking, to facilitate food digestion. Misunderstanding that you can't sleep on your stomach during a nap: many people attach importance to a nap, but they don't pay attention to sleeping position. They either lie prone on the table to rest, or find a shady place to sit and think it's a nap. Note: Although taking a nap is just a nap, it must not be too casual, otherwise it will not only fail to achieve the effect of rest, but also affect your health. Most people don't pay attention to the posture of taking a nap, some sleep on their stomachs, and some simply sleep on their desks. You know, sleeping at a desk will reduce the blood supply to the head, and people will have a series of symptoms such as dizziness, dizziness and fatigue after waking up. At the same time, using your hand as a pillow will oppress your eyes, which will easily induce eye diseases over time. Lying on the table will oppress your chest, affect blood circulation and nerve conduction, and make your arms and hands numb. The ideal nap posture should be lying down comfortably, supine or lying on your side, preferably lying on the right side with your head high and your feet low. This can reduce the pressure on the heart, prevent snoring and help the food in the stomach move to the duodenum. At the same time, we should pay special attention to the surrounding environment when we take a nap in summer, because the muscles relax, the capillaries dilate and the sweat pores are wide after falling asleep. If the air conditioner or fan is turned on and blown at the body, it is easy to catch a cold, arthritis or other diseases. Don't worry after waking up, stand up slowly, drink a glass of water to replenish blood volume and dilute blood viscosity, and then you can do some light activities such as walking. However, people often feel trance when they wake up for the first time, so don't engage in complicated and dangerous work immediately. Three kinds of people are not suitable for taking a nap: it is generally believed that everyone should take a nap in summer, especially the elderly who are in poor health, and think that taking a nap will help restore physical fatigue. Explanation: So, does everyone need a nap? Experts say that newborns, people who lack sleep or engage in mental work and students should take a nap, especially in hot summer, which is very helpful for mental recovery. In addition, heavy manual workers or people engaged in high-temperature operations need to take a nap, because high-temperature workers have a great relationship with the incidence of coronary heart disease, because people who can't take a nap in shifts have a significantly higher risk of coronary heart disease, and taking a nap for half an hour every day can reduce the incidence of coronary heart disease by 20%, so taking a nap has a great role in preventing high-temperature heatstroke. But a nap is not for everyone. Some people pay attention to rest at night and are not used to taking a nap, which has no effect on their health. But there are three kinds of people who are not suitable for taking a nap: first, people over 65 or 20% overweight will increase the blood viscosity and easily cause blood vessel blockage; The other person is a person with very low blood pressure. The sultry weather in summer is not good for people with low blood pressure. In addition, during a nap, blood pressure will be relatively low, making breathing more difficult. The third kind of people have serious obstacles in their blood circulation system, especially those who are often dizzy due to narrowing of cerebral vessels. Because after lunch, the blood in the brain will flow to the stomach, the blood pressure will drop, and the oxygen supply to the brain will decrease. If these people take a nap at this time, it is easy to have a stroke due to insufficient blood supply to the brain. In addition, people with insomnia should also avoid taking a nap during the day. If you can't take a nap in the afternoon, do some other relaxing things, such as listening to music, to keep yourself in a good state of relaxation and better meet the work and study in the afternoon. Linking nap is a scientific regulation of human biological clock, but nap also has taboos: 1. The longer the nap, the better. 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. Supplement: The following information is for people who don't often take a lunch break ~ For modern people who generally lack sleep, taking a nap has a refreshing effect, but if you like taking a nap to make up for your sleep, there are several problems that you must pay attention to. The latest research report in the International Journal of Epidemiology points out that people who love to take a nap, sleep every day and sleep for a long time should pay attention to the risk of heart attack.
