Is it good for swimming when it s cold, and is it good for swimming when it s cold?

When the weather is cold, the number of bear children in the pool is greatly reduced, and the people who come are enthusiasts, and everyone swims without interfering with each other, which is the most suitable time for swimming all year round. I don't know if the water in the indoor pool stays at 23 degrees or 27 degrees, it's not too cold anyway. Warm up properly before entering the water, move after entering the water, and it will not be cold when you go back and forth The water is quite cold, and it is also the easiest time to catch a cold, so it is recommended to put a bath towel by the pool.

Generally, the pool water temperature is between 26 -28, and if it is a competition, the temperature will be lower, basically maintained at 25 -27. Everyone knows that the body temperature of the human body is 37, a temperature difference of nearly 10 degrees, and it is natural to feel cold when you first enter the water. So why does the water in the pool have to be so "low"?

The first reason why the water temperature in the swimming pool is too high to swim is that cold water is an effective radiator.

Whether you're swimming or splashing, it's cold when you first enter the water, but you may even sweat when you play it. This is because exercise consumes energy and also produces heat, and when you exercise, your metabolism accelerates and your body temperature rises, which requires cold water to cool you down and make you feel comfortable.

If the temperature of the water is not lower than the body temperature, then the water, which is a favorable heat dissipator, will not be able to function. Moreover, if you want to be comfortable when entering the water, the water temperature must reach or exceed the body temperature, and at such a temperature, everyone will not swim but take a sauna when you exercise a little, because warm water cannot quickly take away the excess heat generated by exercise.

The second reason why you can't swim in the swimming pool is too high: hot and cold relaxation.

Vascular contraction. When first entering the water, water below body temperature causes blood vessels to constrict to reduce heat dissipation. When you exercise, the heat generated by the exercise will be dissipated and the blood vessels will dilate, which shrinks one piece, so that the cardiovascular system that is not usually able to exercise can also exercise, which is a good prevention of cardiovascular disease.

of the workout. In addition, when cold, blood vessels constrict, and blood flows back to vital organs, such as the brain, to protect them from harm. And when it is hot, the blood vessels dilate, the blood stays more on the surface of the body, and the blood flow to those vital organs will naturally decrease.

The brain is not enough nutrients and oxygen, how can it react quickly? Naturally, it feels chaotic.

The third reason why you can't swim in the pool is too hot: it gives your muscles a sense of strength.

Even the slightest movement of the human body is done by muscle contraction. The muscles that declare their strength have to contract to be seen. Cold water not only helps blood vessels to contract, but also helps muscles to contract, so that people who exercise in water feel full of strength to complete the movement.

But if it's in warm water, it's counterproductive. Warm water, massage your body, and the muscles of the whole body will relax. Comfortable is comfortable, but if you want to move, it will be half the effort, and people will feel very tired.

You can swim in cold weather, and knee pain can go as long as it is not serious, but people with heart disease and high blood pressure cannot swim in winter.

However, if you want to participate in winter swimming, you must start from summer, insist on swimming every day, rinse with cold water after swimming, even if you swim up in winter, you must wash with cold water, although you must do this, after washing and dressing, go to run 800-1500 meters, the heat slowly spreads from the inside to the outside, this is the most comfortable, because this can force the cold of the body out, do not wash with hot water, otherwise the cold will invade the body and be more cold.

Winter swimming can prevent and assist many diseases, such as: arteriosclerosis, joint pain, chills, susceptibility to colds, etc., the swimming time is reduced with the decrease in water temperature, even if it is snowy and only swim 50 or 100 meters, you must insist, so that it can be effective, if you can persist until 2-3 years later, you will find that your body will have completely different changes.

I've been swimming all year round, almost 30 years, it's hard to have a cold all year round, I hardly take any medicine, even if it's a bit like a cold (cold season) dizziness and headache, just sleep for one night and be fine, the next day it will be the same as usual.

It doesn't matter, the water temperature in the swimming pool is room temperature, and you should warm up before entering the water!

There is no harm, the exercise is very good, I will first throw bricks and jade and say a few words: first, the preparation activities before entering the water must be done sufficiently, the weather is cold, and people's joints are beginning to tighten. Try to be as comprehensive as possible in the activities of the whole, according to.

It's not a matter of cold weather, you may be a little deficient in calcium, go to the hospital to prescribe some calcium supplements, and take them every day, so that you can supplement calcium. Of course, it's best not to swim when it's cold. Prone to colds. More attention should be paid to maintenance.

As long as you are in good health, you can do it. Swimming can bring a lot of heat to the body. Of course, beware of colds.

Suitable, but requires your physique to be okay. Winter swimming is beneficial.

If the body is frost-resistant, you can consider it.

It depends on the physique, but there are many benefits to insisting on swimming.
