Is winter suitable for indoor swimming? Winter is actually suitable for indoor swimming, but to control the water temperature, many people think that winter is not suitable for swimming or only winter swimming is allowed, which is inaccurate. Swimming is a good exercise. If people can't stand the cold winter swimming, they can choose to swim indoors in winter.
Swimming in winter is generally from outdoor to indoor. This can protect it from outdoor air pollution. On the other hand, when swimming, the blood vessels of the skin contract sharply due to cold water, and a large amount of blood is driven into internal organs and deep tissues. After the blood vessels contract strongly, they will definitely relax accordingly, so that the blood vessels can be exercised one by one, and the human body can adapt to this alternating change of cold and heat more quickly.
Generally speaking, it may be maintained at about 29℃ in summer due to the weather, and it is almost the same in winter, but this temperature is completely acceptable, especially for a frequent swimmer, and it can even be said that swimming will be more comfortable, and it may be a little cooler for a beginner. However, you should know that the standard temperature of swimming pool is between 25-29℃. As long as you have been swimming in the water, you will soon get used to the water temperature. As for the room temperature, don't worry. As long as the swimming pool is a little standardized, it will generally maintain a temperature that is more comfortable for the public.
The benefits of swimming in winter enhance heart and lung function.
Because swimming is a whole-body exercise, it can help us stretch our whole body, help us lose weight, and enhance our cardiopulmonary function and vital capacity. When we swim in the water, many organs of the whole body can participate in sports, which can accelerate the blood circulation in the body, make the blood full of oxygen and provide various nutrients for the organs. At the same time, the blood flow speed is accelerated, which can increase the beating ability of the heart and exercise its beating. Therefore, regular swimming can enhance our cardiopulmonary function.
Enhance immunity
In summer, the water temperature in the swimming pool is about 28 degrees. Because of the water temperature, swimming in the water consumes a lot of heat and energy. Therefore, in order to supplement the heat energy needed by the body and maintain the balance between cold and heat, the metabolism of the human body will be accelerated at this time to adapt to the surrounding environment and prevent colds.
Lose weight and keep fit.
When swimming, we were all immersed in the water because we were all mixed up. Because of the temperature in water and the great resistance of water movement, we will consume a lot of heat. According to the research, swimming in the swimming pool for 20 minutes is equivalent to the heat consumed by exercising on land for about an hour, so we can find that swimming in the water is a very good choice for friends who want to lose weight, so swimming is also one of the good ways to lose weight and shape.
Prolong life
Everyone knows that exercise can improve health and prolong life, but research further confirms that swimming is the best in both aspects. Researchers at the University of Southern California followed 40,547 men aged 20-90 for 32 years. The results show that the mortality rate of men with swimming habits is nearly half lower than that of men who often run, walk or don't exercise. It can be seen that swimming is definitely a good way to live longer!
skin care
When people swim, water washes away the skin, sweat glands and fat glands, which plays a good role in promoting blood circulation and making the skin smooth and elastic. In addition, when exercising in water, the influence of salt in sweat on the skin is greatly reduced. In addition, because swimming overcomes the resistance of water rather than gravity, muscles and joints are not easy to be injured, which is very safe. Especially in the cold season, swimming can improve the body temperature regulation function and prevent colds.
Precautions for indoor swimming in winter 1, fully equipped.
In addition to swimsuits, goggles, swimming caps and other equipment, you must bring slippers when swimming in winter to avoid catching cold on your feet; After a rest or bath, bring a bath towel or towel coat to keep warm. In addition, the room temperature in the swimming pool is high and the humidity is high. It is recommended to wear clothes that are relatively simple, easy to put on and take off, and have good warmth, so as to change clothes.
2. Adequate preparation activities
Compared with summer, getting ready for swimming is the key. Because of the low temperature in winter, the joints are fragile. You must move all your joints before you go into the water. It is recommended to do more stretching exercises such as vertical jumping, shoulder pulling and arm shaking, and focus on warming up the legs, arms and waist to prevent cramps during swimming. Generally speaking, the preparation time is about 5- 10 minutes, and it feels a little red, just a little hot.
3, rest, drink water, pay attention to keep warm after the shower.
Many swimmers don't pay attention to keep warm when resting or going to the toilet, which leads to a rapid drop in body temperature and a cold. The human head is the easiest to dissipate heat. If the hair is wet after using water and showering, it will easily lead to rapid heat loss. Therefore, put on a bath towel after taking a break, dry your hair in time after taking a shower, get dressed, and if possible, it is best to dry your hair with a hair dryer.
