Is winter swimming effective for losing weight? What should you pay attention to when swimming in winter?

　　1. Benefits of winter swimming

　　Winter swimming has many benefits for the body, specifically the following benefits:

　　1. Increase the elasticity of blood vessels and accelerate blood flow, which can reduce the deposition of fat particles and cholesterol on the blood vessel walls and prevent the formation of arteriosclerosis and thrombosis.

　　2. Winter swimming can enhance cardiopulmonary function. After winter swimming, it will accelerate blood circulation and enhance myocardial contractility.

　　3. Can regulate high blood pressure, reduce high cholesterol and Hyperlipidemia。

　　4. It can improve physical fitness. After winter swimming, people will eat well and sleep soundly, and it can also reduce cold Probability.

　　2. Winter swimming can help you lose weight

　　In fact, you can lose weight by swimming in winter, and you can also lose weight by swimming in summer, let alone winter. Swimming in winter will consume more calories in the body, but remember to persist. If you don't persist, fat loss will only take a while. Only persistence can play the role of losing weight.

　　3. The best time for winter swimming

　　The best time for winter swimming is around December. In fact, swimming several times a week and then transitioning to winter naturally will be better for the body. Generally, winter swimming is best done in the afternoon, but it can also be done in the morning, but you can’t go into the water immediately after getting up in the morning. At least half an hour has passed before you can do it.

　　4. Swimming time needs to be determined according to water temperature

　　Under normal circumstances, the water temperature is different, and the specific activity time in the water will also be different. In 14-degree water, you only need to swim for 14 minutes. Then the swimming temperature in the water will be adjusted according to the water temperature. Every time the water temperature drops by one degree, you need to swim in the water for 1 minute less.

　　Precautions for winter swimming

　　1. Gradually entering the water is the body’s need to adapt to objective conditions. Many people experience cramps, dizziness, and a sudden increase in heart rate when swimming, which are all related to sudden entry into the water. The human body needs a transition from rest to violent movement so that all parts of the body can adapt to the needs of movement.

　　2. Sudden entry into water can easily induce illness. Because the body is under a temperature difference where the water temperature is too low, the stimulation of suddenly entering the water will be more intense. The body will not be prepared in time and will be unable to accept the strong stimulation, which can easily lead to the occurrence of cardiovascular disease and endanger life.

　　3. Failure to observe clearly can easily delay rescue. The moment you enter the water during winter swimming is a time when your body is prone to problems due to intense stimulation. If you slowly drain the water, others can see the body reaction of the person entering the water, and if rescue is needed, they can quickly take action.

　　4. Injury is easy to occur in cold weather. It’s freezing cold in winter, and the surface near swimming venues is often frozen and slippery, making it easy to fall. When diving, it is often easy for the body's center of gravity to become unstable, to fall, or to deviate when diving into the water. If a person collides with a swimming person when jumping into the water, an accident is more likely to occur.

　　5. Ice cubes in water are easy to skin scratched. Winter swimming often requires opening the ice surface, so the water surface for winter swimming is usually not wide and is not suitable for diving. Moreover, there are often small ice cubes in the water that are broken but cannot be fished out. The edges of these small ice cubes are relatively sharp. These ice cubes float in the water and are often difficult to see because they are transparent.

　　6. Foreign objects underwater can easily cause accidents. In the few years we have been swimming, there have been accidents in which swimmers died after diving and hitting their heads on rocks on the bottom of the water. They are all experienced swimmers and usually have good swimming skills, but the accident happened because of their carelessness. As the saying goes, “Those who drown are those who know how to swim. ”The reason is that because people are familiar with or proficient in something, they become careless and loose-minded when doing it, resulting in a very bad situation. On the contrary, if you are not familiar with or proficient in something, you will be very cautious when doing it, so it is less likely to cause problems. To avoid accidents, it is best not to dive. When swimming in winter, the swimming action should be gentler and safer.
