Benefits of swimming in winter:
1, which is helpful to the blood circulation of the whole body. Water can massage the body when swimming. When the skin is cold, vasoconstriction can prevent and alleviate the occurrence of arteriosclerosis, hypertension, diabetes, cardiovascular and cerebrovascular diseases in middle-aged and elderly people.
2, can improve the cold resistance and immunity. Swimming promotes metabolism, thus improving the body's ability to resist cold, thus preventing respiratory diseases.
3. It can enhance the function of respiratory organs and reduce or prevent respiratory diseases that are prone to occur in winter. The density of water is 800 times higher than that of air, so people have to bear a lot of pressure when swimming. Therefore, respiratory muscles should strive to overcome the pressure of water, deepen breathing and increase vital capacity, thus enhancing their adaptability to environmental stimuli and reducing the occurrence of diseases.
4. Regular participation in winter swimming has obvious physical fitness and anti-aging effects.
This is a good exercise to lose weight. Among all kinds of weight-loss exercises, swimming is an exercise worthy of recommendation. People who swim regularly have strong bodies, developed chest muscles and streamlined bodies; People who can't swim, soaking in water and having a water fight all have some effects on losing weight.
Swimming is good for losing weight because:
1, swimming consumes a lot of energy. This is because the resistance of water when swimming is much greater than that of air when moving on land, which is 800 times that of air. Walking in water is laborious. If you swim again, you will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also beneficial to heat dissipation and consumption. So swimming consumes much more energy than running and other land projects, so the effect of losing weight is more obvious. Winter swimming is a higher level of swimming, and the weight loss effect is particularly obvious.
2. Swimming can avoid sports injuries of lower limbs and waist. In the process of long-distance running to lose weight, obese people have to bear a great burden on their bodies (especially the lower limbs, waist and heart), which reduces their exercise ability, is easy to get tired, greatly reduces their interest in losing weight, and also damages the joints, bones and heart of lower limbs. When swimming in water, a considerable part of obese people's weight is borne by the buoyancy of water, which makes their lower limbs and waist much easier and greatly reduces the risk of joint and bone injury.
3. Enjoy the natural massage service. When swimming, the buoyancy, resistance and pressure of water is an excellent massage for human body, and it can also beautify the skin. In view of the above reasons, obese people can really take swimming as the main exercise to lose weight. But you must be prepared before swimming and pay attention to safety to prevent accidents.
Winter swimming is being accepted by more and more people and has become a fashionable exercise method. However, although winter swimming can strengthen the body and prevent diseases, it should also be scientific. Not everyone is suitable for winter swimming, especially patients with severe heart disease, hypertension and skin diseases.
Swimming in winter is good, but not for everyone;
Winter swimming is called "the game of the brave", and more and more winter swimmers jump into the cold water to show their "heroic qualities". However, Zhang Baocang, director of the office of the Winter Swimming Committee of the China Swimming Association, said in an interview that although winter swimming has many benefits, it is not suitable for everyone.
Three kinds of people are not suitable for winter swimming:
Teenagers under 1 and 16 and elderly people over 70 years old are not suitable for winter swimming because of their special physical conditions;
2. Patients with mental disorders are not suitable for winter swimming because of lack of self-control;
In addition, according to the doctor's examination, people with serious organic diseases such as heart disease, coronary heart disease, tuberculosis, hepatitis, stomach disease and respiratory diseases are not suitable for winter swimming.
Winter swimming needs to pay attention to the following matters:
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, take a shower to keep warm.
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.
Tips:
As a special fitness exercise, beginners should be cautious when deciding whether to swim in winter, and it is best to listen to the doctor's advice first. Moreover, for beginners, ordinary people must swim in winter step by step, adhere to it for a long time, and eat reasonably. The time for launching each time should not be too long, and the degree should be mastered according to the comprehensive conditions such as water temperature, temperature, weather, personal fatness and mood (the launching time of a general swimmer = water temperature × 1.0+ 1). Rome wasn't built in a day, and it didn't swim in winter. It must start in summer and persist in autumn to adapt to the gradual change of water temperature. Otherwise, it is not only useless, but also harmful to the body.
