Some people who can't swim will also come to feel the coolness of the swimming pool. I believe that there are many people who love swimming and are good at swimming. So do you know what benefits swimming has to the human body? Please listen to the editor’s detailed explanation below.

Swimming is one of the most popular fitness exercises. Proper swimming exercise can not only bring people psychological pleasure and shape a smooth and graceful body shape, but also enhance the function of the cardiovascular system, strengthen physical fitness and improve coordination.

Swimming is the sport with the lowest strain and injury rate, so it is a lifelong fitness exercise.

What are the benefits of swimming?

Improve the function of the cardiovascular system

If you persist in long-term swimming exercises, the volume of the heart will increase, the myocardial contraction will become stronger, the resting heart rate will slow down, the stroke volume will increase, the blood vessel walls will thicken and increase their elasticity, and the efficiency of the cardiovascular system will be improved.

Improve the function of the respiratory system

Because the density of water is more than 800 times greater than that of air, the pressure a person is subjected to in water is much greater than that in air. As the pressure on the chest and abdominal cavities increases in water, the respiratory muscles are forced to use greater force to breathe. Regular swimming can increase the strength of the respiratory muscles and improve the function of the respiratory system.

Improves the strength of the muscular system

Swimming is a sport that involves the whole body. Long-term training can improve muscle strength, speed, endurance and joint flexibility. Correct swimming technique requires muscles to stretch before contracting and exerting force. This type of exercise is conducive to continuously improving our flexibility and strength.

Make the body proportions more reasonable and shape a healthy body

The process of swimming creates resistance with water, which has the effect of losing weight. People who swim for a long time generally have a slender figure, broad shoulders, flexible waist and well-proportioned body shape.

Improves body temperature regulation

Since the temperature of water is generally lower than the air temperature and the thermal conductivity of water is dozens of times stronger than that of air, people lose much more heat in water than in the air. Regular swimming can improve the body's ability to regulate temperature, making it better able to withstand changes in external temperature.

Disease prevention, treatment and rehabilitation

Due to the stimulation of cold water, long-term swimming exercises can enhance the body's ability to resist cold and adapt to the environment, prevent diseases such as colds, and make the body stronger. Because the body lies flat when swimming, and the buoyancy can fully stretch the spine, it has a certain rehabilitation effect on some spinal patients. Swimming can also be used as an exercise prescription to treat some chronic diseases, such as chronic gastrointestinal disease, chronic bronchial asthma, etc. For some people who are not suitable for upright exercise, such as obese patients, if they adopt running and other methods, the excessive burden on the legs and feet due to gravity can easily lead to injuries. At this time, swimming is a good alternative exercise method.

Tempering willpower promotes mental health and intellectual development

Learning to swim requires overcoming certain difficulties. People who are just beginning to learn to swim generally have a fear of water. The unfamiliarity with the water environment makes them feel fearful. The process of learning to swim is the process of overcoming difficulties such as fear, cold, and fatigue. It is a good exercise for one's willpower. Swimming is also beneficial to the development of intelligence. The flow characteristics of water and swimming techniques put forward many special and subtle requirements for body balance. The process of mastering swimming techniques is a process of full coordination between the nervous system and muscles. It requires experiencing the special feeling of water, which is a benign stimulation to the nervous system. People who insist on swimming exercises will definitely benefit from it.

Some precautions for swimming

1. Avoid swimming after strenuous exercise

Swimming immediately after strenuous exercise will increase the burden on the heart; the sudden drop in body temperature will weaken the resistance and cause colds, pharyngitis, etc.

2. Avoid prolonged exposure to the sun and swimming

Prolonged exposure to the sun can cause sun spots or acute dermatitis, also known as sunburn. To prevent sunburn, it is best to use an umbrella to shade yourself after going ashore, or rest in the shade of a tree, or use a bath towel to protect your skin, or apply sunscreen to exposed areas of your body.

3. Avoid swimming without warm-up exercises

The water temperature is usually lower than body temperature, so you must do warm-up exercises before entering the water, otherwise you may feel uncomfortable.

4. Avoid eating immediately after swimming

It is advisable to rest for a while before eating after swimming, otherwise it will suddenly increase the burden on the gastrointestinal tract, which may easily cause gastrointestinal diseases over time.

Just think about it and you will know how cool and comfortable it is to swim in the swimming pool in this hot summer. But at the same time, you should also pay attention to some precautions for swimming, so that you can exercise your body and increase your knowledge while ensuring your health. So don't blindly follow the trend and consider whether your physical condition is suitable for swimming.
