In the hot weather, it is easy to cool down and cool down. However, when the weather changes that day, there are still people who are enthusiastic about this. For some health-conscious people, cold water treatment that challenges body tolerance can help nourish. In fact, soaking in cold water can make many people energetic, but it can be dangerous for some people.

According to the news draft of the American Career Association, the so-called cold water treatment method refers to strengthening the immune system and improving cardiovascular health by immersing the body in cold water or exposing it to cold air, but there are still few evidences that cold water treatment is beneficial to health.

{9 Tipton told the Daily Telephone that entering cold water will cause involuntary gasping, rapid breathing or excessive air circulation, which is caused by shock caused by sudden soaking in cold water, resulting in sudden increase in heart rate and blood pressure. From data, 60% of people who died in cold water died from the impact of this "cold shock response".

Research after the desolation of the iron daniel has led to a widespread understanding of the risk of hypothermia (or abnormality) caused by soaking in cold water. Now people understand that one minute after immersion in water will cause serious danger. Tipton said that when you can’t breathe and your breathing is out of control, your heart is under heavy burden.

When the skin suddenly becomes cold, it can cause surface nerves and muscles to become cold, which will cause you to lose your physical ability within 10 to 20 minutes. Tipton points out that all this happens before your temperature is too low.

Although you can be engaging in cold shock reactions, which can make your experience safer and reduce the possibility of heart attack or drowning, Tipton said that the pre-determining condition that entering cold water causes drowning or heart attack is proven.

As for people's pleasant feelings about the winter swimming, Tipton explains that the cold shock reaction releases Calemon, which causes warning and awakening as part of the fight-escape reaction. People who love this say this keeps them alert and prepare for the new day, and this is actually due to the body's pressure reaction.

Why is warm after winter swimming important?

Why do people feel the coldest after leaving cold water after winter swimming? This is a phenomenon called "afterdrop", which will lead to a decrease in the core temperature of the human body. So, if you don't take very aggressive warmth after you leave the water, you may get cold for a long time.

In addition, there are also studies that show that if your body temperature is too low, it will actually weaken your immune system. What is more noteworthy is that for people with a history of medical treatment, soaking cold water is a dangerous thing. According to the advice of the Professional Physicians Association of British Career Rehabilitation, water temperatures between 26 and 33 degrees Celsius are the safest for people with a psychiatric disease.

Tipton suggests that health checks should be conducted before participating in winter swimming activities to ensure that you are healthy. Since this is a major challenge for human physiology, if you are trying it, you must be fully prepared and do it safely, preferably with experience supervision.

Even if you have taken all the correct precautions, Tipton also advises that staying in the water for more than two minutes is unnecessary. Most of the benefits people reported came from the first two minutes. The longer you stay in the water, the more dangerous it is.
