Stroller and others concluded: "If the basal body temperature of human body is reduced by 1℃, the life span can be extended by at least 10 years; If 1.7 C is reduced, the service life can be extended by 30 years.

Matters needing attention in winter swimming
According to People's Daily, swimming in outdoor waters with a temperature lower than 10℃ or a water temperature lower than 17℃ can be regarded as winter swimming. Winter swimming is a good exercise, which is good for your health. Sticking to scientific winter swimming can promote blood circulation, speed up metabolism, improve the cold resistance of human body, strengthen many functions of the body, and thus enhance the resistance of human body to diseases.

It should be noted that although winter swimming can strengthen the body, it is not suitable for everyone. According to Huaxi Daily, people with serious organic diseases such as heart disease, coronary heart disease, tuberculosis and hepatitis are not suitable for winter swimming, because after being stimulated by cold water, patients' blood vessels will contract, which may cause stroke, myocardial infarction and even sudden death in a short time.

In the process of winter swimming, some unexpected situations may occur, which will do harm to the body. Xi Daily reminds us that in order to ensure our own safety, we should pay attention to the following points when swimming in winter:
1. In the process of winter swimming, people are prone to hypoglycemia and severe hypoglycemia shock, so pay attention to supplement some carbohydrates before winter swimming;

How to change water in the swimming pool?
The answer is 24-hour circular filtration. The backstage machine room of swimming pool generally includes three systems: circulating pump, sand filter cylinder and heating pipe. Their functions are to provide water circulation, water quality treatment and constant temperature control. In addition, the circulating pipeline system will have a water replenishment bypass to replenish clean fresh water. Therefore, when we swim, the water is always in a state of circular renewal, which is not what some people think.
But many times, we find that the water in the pool is still very turbid. Objectively speaking, this problem is that there are too many people swimming, which leads to too many impurities and exceeds the load of the water treatment system. On the other hand, subjectively, it may be the result of poor site management, irregular operation of employees and cutting corners. In short, the management of instruments, equipment and personnel requires both hands.
Who is not suitable for winter swimming?
Winter swimming has the functions of strengthening the body, enhancing heart and lung function, promoting blood circulation and enhancing resistance. However, not everyone is suitable for winter swimming. Generally, people with heart disease and respiratory diseases are not suitable for winter swimming. People who are suitable for winter swimming should also pay attention to scientific winter swimming in order to make the effect of physical fitness more obvious. Winter swimming is a gradual process.

It is worth noting that warm-up exercises should be done before launch. Never dive, but get used to the water temperature before you go into the water. People who insist on doing winter swimming all the year round have a very low probability of suffering from diseases such as arteriosclerosis and high blood pressure. Winter swimming is a brave sport, which has multiple benefits of cultivating a healthy lifestyle and honing a strong will.
