It is more common in northern my country, especially in recent years, the number of winter swimmers has grown rapidly. But it should be noted that participating in winter swimming should be done with appropriateness as the first priority.

Winter swimming has the characteristics of cold stimulation and high heat dissipation, which can promote human blood vessel contraction and expansion, enhance blood microcirculation, improve human immune function, help prevent cardiovascular disease, improve the regulatory function of the cerebral cortex, and strengthen the function of the human respiratory organs and digestive system.

Is winter suitable for swimming? What should you pay attention to when swimming in winter? Winter is very suitable for swimming, and swimming in winter is very good for your health.

1. People who participate in winter swimming generally benefit. Winter swimming improves the quality of life. I eat better, sleep better, have more energy, think more quickly, rarely catch a cold, and am less likely to suffer from other diseases.

2. It can cure diseases and resist aging, and has a certain regulating effect on high blood pressure; it can reduce high blood lipids and high cholesterol within a certain range. Winter swimming can enhance the ability to adapt to cold stimulation, improve the body's resistance, and delay the aging process.

3. Winter swimming is like vascular gymnastics, which increases blood vessel elasticity, accelerates blood flow, reduces fat particles and cholesterol deposited on blood vessel walls due to sprinting, reduces and delays arteriosclerosis, and prevents the formation of blood clots and coronary artery infarction.

4. It can enhance cardiopulmonary function. After winter swimming, myocardial contractility is enhanced, blood circulation is accelerated, and the functions of various body systems are promoted and develop in a positive direction.

5. It can enhance one's immunity. Immunity refers to the body's prevention and resistance to invading pathogens. After winter swimming, many indicators of winter swimmers, such as lymphocytes, white blood cells, macrophages, immunoglobulins, etc., are significantly increased compared to before swimming.

6. Winter swimming can promote endocrine function. When the human body is exposed to strong cold stimulation, it is immediately reflected through the nervous system to the pituitary gland, adrenal glands, pancreas, gonads and other glands, and each gland secretes corresponding hormones, the so-called neurohumoral. Then the physiological functions of the corresponding organs are adjusted through the corresponding nerve centers to establish a new balance. Logically, the secretory functions of various glands should decline with age, but tests have shown that the secretion of thyroid hormone in winter swimmers has increased. Testosterone levels also increased.

7. Winter swimming can delay the decline of the nervous system, especially the central nervous system.

8. Winter swimming enhances the function of the digestive system. Due to excessive consumption of heat energy, the digestive ability is enhanced, so the appetite increases greatly and the body's metabolic function is generally enhanced.

In addition, people generally feel psychologically satisfied through winter swimming exercises. The sense of comfort produced by the strong cold stimulation and the continuous psychological and spiritual recharge of winter swimming will definitely have a positive impact on the physiological functions of various systems of the body. In this way, the body and mind are balanced at a higher level, creating a virtuous cycle. It is not difficult to understand why winter swimmers seek out hardship and insist on winter swimming for many years or even for their entire lives.

Winter swimming is the highest form of cold water exercise. The following matters should be noted: Winter swimming is not suitable for patients with serious illnesses such as heart disease, liver disease, kidney disease and emphysema, as well as children who have not yet fully developed; Winter swimming is not allowed in the early and middle stages of a cold (including a mild cold), but it is allowed in the late stages of a cold and when you are about to recover, and it is strictly prohibited to swim in winter after drinking; The amount of swimming must be controlled in winter swimming. Under normal circumstances, you can swim for about 20 minutes (about 200 to 500 meters) when the indoor water temperature is 10℃ to 14℃. When the water temperature is below 10℃, you should swim 1 minute less for every 1℃ drop in temperature. Don't exceed the limit; The safe body temperature for winter swimming exercise is an axillary temperature of no less than 27.4℃ measured within 5 to 10 minutes after getting out of the water. A temperature lower than this is not good for the body. In short, it is advisable not to shiver.

In addition, there are four principles to master when swimming in winter: swim in the sun, not in the shade; swim in the rain, not in the wind; swim in the snow, not in the fog; and swim in clear water, not in muddy water.
