Why is the water temperature in the swimming pool too hot
Generally, the temperature of the swimming pool is between 26 ℃ and 28 ℃. If it is a competition, the temperature will be lower, basically maintained at 25 ℃ - 27 ℃. As we all know, the body temperature is 37 ℃, with a temperature difference of nearly 10 degrees. Naturally, when you first enter the water, you feel cold. Why does the water temperature in the swimming pool have to be so "low"?
The swimming pool water temperature is too high cannot swim the reason one: the cold water is the effective radiator
With the same amount of exercise, swimming consumes more energy than land sports, which is why people love swimming. But you don't know that it also determines the temperature of the pool.
Everyone has this kind of experience: whether it's swimming or playing in the water, it's cold when you just enter the water, but it may even be hot enough to sweat after playing. This is because exercise will produce heat while consuming energy, and when exercising, your metabolism will speed up and your body temperature will rise, which requires cold water to cool you down and make you feel comfortable. If the water temperature is not lower than the body temperature, then the favorable heat radiator, water, will not work. Moreover, if you want to be comfortable when you enter the water, the water temperature will reach or exceed the body temperature. At such a temperature, a little exercise is not swimming but sauna, because warm water can't quickly take away the excessive heat generated by exercise.
Swimming pool water temperature is too high, can't swim two reasons: cold and hot relaxation, blood vessels stretch
Just into the water, below body temperature of the water will make the skin blood vessels contracted to reduce heat emission. After exercise, the heat generated by exercise will spread out and make the skin blood vessels dilate. This contraction will make the cardiovascular system which is usually not able to exercise also exercise. This is a good exercise to prevent cardiovascular disease. In addition, when it's cold, blood vessels in the skin contract, and blood flows back to important organs, such as the brain, to protect them from damage. When it's hot, the blood vessels of the skin dilate and the blood stays more on the surface of the body, so the blood flow of those important organs will naturally decrease. Brain nutrition and lack of oxygen, but also how to respond quickly? Naturally, it feels chaotic.
Swimming pool water temperature is too high, can't swim three reasons: let muscle produce a sense of strength
Even a tiny movement of the human body is completed by muscle contraction. The muscles that proclaim strength have to contract to be seen. Cold water not only helps the blood vessels to contract, but also helps the muscles to contract, making the people who exercise in the water feel full of strength to complete the action. But if it's in warm water, it's counterproductive. Warm water, massage like pat your body, the whole body muscles will relax. Comfortable is comfortable, but if you want to move, you can get twice the result with half the effort, and people will feel very tired.
