Dr. Mark Harper recalls his first recollection. Cold water Twenty years ago in southern England. It was August, but the initial shock of the flungji was able to breathe.
Harper said his shock was “lasted for 1 to 2 minutes until it was recombinant and thought about anything other than the cold.” The amazing sensation soon replaced his inconvenience.
“I think I feel good for the first time. Take Nippy Dunk. “I didn’t expect it.”
Claim Cold water Going up for centuries. Thomas Jefferson, a major author of the Declaration of Independence and a third president of the United States, wrote at the end of his life about using cold foot baths every day for 60 years. He also owned a book about the history of cold water bath in 1706.
Evidence of the positive health impact of swimming in chilly water Bath on ice Or a cold shower, Scientific confirmation is still lacking.
But Harper who became the rules Cold water swimmer After him, he said that there is a strong signal that people can get the benefits of mental health from their activities. He had a positive effect on depression and general welfare.
Harper said to the Associated Press: “At this time, cold water flooding is a very powerful basis for mental health, but it is not certain evidence.
Promotion of mental health
Harper said his initial experience of cold water swimming caused his professional curiosity. As a doctor, he wondered if a simple physical shock had been clinical to treat depression. He cited the biological phenomena of hormones, and the stressful factors introduced at low doses create a positive response.
The muscles and bones are stressed (for example, exercise with weight).
Harper admitted that the positive effect he observed could be the result of placebo effects.
In the case of cold water flooding, the benefits can help people, exercise itself, or simply accept challenges and achieve them to improve confidence.
“Personally, I think it’s everything, and I think the cold is an additional effect.“ I think we have a good physiological basis for him. Basic science says that the cold has a very strong effect on the body.
“What we say is an intervention that has a beneficial effect on mental health when it is clinically used. Therefore, it does not matter which aspects produce a positive effect.”
Harper quoted it as a general reaction among the first timers he said.
They often said, “The fact that I have worked in this means that I can do anything.” “This is a confident architect and insisted on because people enjoy too much.”
I know the danger when I start
Dr. Mike Tipton, a physiologist at Potsmus University, wrote a paper with Harper, who studied an extreme environment and two researchers a few years ago. This title emphasizes the potential advantages and dangers of suddenly falling temperature and stimulating the body.
“As with other environmental components such as pressure, heat and oxygen, cold water can be good, bad, threat or treatment depending on the situation.
One of their discoveries: activity indicates risk. The death of cold water flooding is not uncommon. Due to the impact of cold water, people can breathe and drown with people. But Tipton told AP that it can manage risks with common sense and preventive measures.
How cold is it, how long does it take?
You don’t have to go to the extreme for potential rewards. It is enough to enter the water at a temperature of 20-15 degrees Celsius (68-59F) and stay for a few minutes.
Tipton has a more advantage if the water gets colder than that, but limited exposure.
Tipton said, “If you ask you to follow a protocol if you think this will do well, I will not fall into the water below 12C (54F) and not stay for more than 2 minutes.
Tipton and Harper said that all the advantages of cold water flooded were caused by the body’s cold storage reaction. Suddenly falling skin temperature, release of stress hormones, and releasing endorphins and anti -inflammatory effects.
Tipton warned of long spells in ice baths.
Tipton said, “I was sitting in the water for a long time I filled with fear.” “This can destroy small nerves, the blood vessels of the limbs and can cause cutting in the same way as the statue can do.”
Harper, who has been stretched for four hours in open water, advised the boundaries.
Harper said, “People think it should be very cold and very long and long.
Be safe. You are tropical animals
Tipton did not try to be a “fun police”, but if he plunged, he offered attention and medical checkups. He said that humans must adapt to the cold and are considered a “tropical animal” that is more suitable for warm conditions.
Human resting body temperature is about 36.5 ~ 37.5 degrees (97.7 ~ 99.5f). Because of this, cold water floods are stressed and causes risks for cardiovascular and respiratory systems. Not to mention the risk of drowning.
Tipton said, “We don’t want to stop people doing so, but I want to make sure they do it by maximizing benefits and minimizing risks.
He suggested that he swims in a life -saving area or goes with skilled outdoor swimmers. He also proposed to know the water body you swim. Risks include tide, temperature, depth and pollution.
Tipton said, “Taking tropical animals and putting them in cold water will be the biggest stress that most people will experience in their lives.
Instead of jumping, he suggested to go into the water in a controlled way.
“It’s wise about it.” “Standard.”
