Swimming is a special sport. If you insist on swimming for a long time, will it lead to cold invasion?

"Cold" is a concept of traditional medicine and one of the six evils. It is often called cold evil. In the definition of traditional medicine, all exogenous pathogens with the characteristics of "shrinking substances and slowing down molecular movement" are collectively called cold pathogens. This characteristic of cold pathogen is described as "cold leading to suction" and "cold stagnation", and the main characteristics of diseases caused by it include pain (because cold affects blood circulation, resulting in insufficient local blood flow and stimulating painful nerves, and pain is not feasible) and fear of cold and no sweat (this is easier to understand).

Therefore, the so-called chill does not simply refer to being cold or catching cold, but refers to a series of health problems related to "cold evil" caused by bad external cold stimulation. If the body's resistance is enough, then there will be a "healthy memory, and evil can't be done."

Because the whole exercise process is carried out in water, the water environment also affects the exercise effect to some extent. Swimming is a special sport. Because the whole exercise process is carried out in water, the water environment also affects the exercise effect to some extent. Exercise in water has many advantages, such as buffering your movements, thus greatly reducing the possibility of injury. Moreover, the water temperature is relatively low when swimming, and swimming consumes more energy. However, many people will have such doubts.

We must warm up before we go into the water. A good warm-up exercise can warm up our bodies first, which will raise the temperature of our muscles. When we enter the standard pool temperature, we won't feel cold at all, and we can swim in the water at the same time. Uninterrupted swimming can ensure the temperature of our bodies and effectively prevent the invasion of cold.

For the body, swimming is a process in which the heat generated by the muscles of the body resists the external water temperature. The ideal situation is that the muscles of the body generate heat, so that the body temperature can always restrain the low water temperature around and the chill brought by the air after landing.

Healthy people, who go swimming during the day in midsummer, don't have to worry about any cold current invasion at all. If the body function is excellent, the muscles are strong and the heat is sufficient, it is no problem to swim in the water in the slightly cold spring and autumn. But if the body is not strong enough (muscle ability is the key to determine the level of work fever), or the environment is too cold, then the balance beneficial to the body does not exist, and the cold invasion is a real event.

In autumn and winter, everything is dormant, hands and feet are bound, activities are reduced, and the energy dissipated by the body after a summer of venting is well supplemented. At this time, the best work and rest is to eat and sleep well, sweat less and do light exercise.

Swimming is an aerobic exercise, which is very suitable for people of all ages. When swimming, the resistance, pressure and buoyancy of water are a very good massage and exercise for the muscle tissues of all parts of the body.

Swimming can not only promote the circulation of blood and lymphatic system, increase heart load and contractility, increase urination and reduce tissue edema; It can also balance the nervous system response, relax muscles and relieve emotions. People of different ages and different physical states can adjust different swimming postures, intensities and water sports modes according to their physical conditions.

Swimming has also made great achievements in losing weight. Swimming is a whole-body aerobic exercise, which can accelerate the energy consumption of the body and is particularly effective in reducing abdominal fat. In addition to low-fat and low-sugar diet, swimming and dumbbell combined with resistance exercise can increase the speed of weight loss and achieve the health goal of paying equal attention to weight loss and bodybuilding.

Swimming is the best way of all sports in the fitness field. Because water has resistance, it will make us consume more enthusiasm in a short time. At the same time, water has buoyancy and little wear on joints.

Especially the elderly, some of whom can't run. Their legs and feet are not flexible and their knees are not good. At this time, they can choose swimming.

We insist on swimming for a long time, the main purpose is to exercise. You can usually stay in the water for about an hour. We haven't worked underwater for a long time, so we won't be attacked by the cold. So, don't worry, don't worry.
