What are the benefits of diving?

Diving is different from land sports because it is not affected by gravity at all. You can walk freely in the water with some underwater equipment like a fish. So what are the advantages of diving compared with other sports? Let me tell you the benefits of diving.

The benefits of diving

Diving is beneficial to the overall shaping of people's body and mind.

The advantage of diving is not only that the fantastic world in the water brings great spiritual enjoyment to people, but also that regular diving can develop muscles in all parts of the body, improve physical qualities such as strength, speed, endurance and flexibility, cultivate people's will to be brave, tenacious, cooperative and cautious, increase intelligence, self-confidence and leadership, and improve academic performance. For example, for a child aged 10, not only can he learn how to install complex equipment, but he can also master the necessary underwater survival skills. After becoming qualified divers, students will find that they have learned a lot, not only diving, but also knowledge of physics, physiology and oceanography. In addition, if they continue their educational journey and enter the fields of geography, anthropology and history.

It is precisely because of this that the education departments of some developed countries such as the United States can apply for credits from local universities or colleges with the PADI diving qualification certificate (the most influential diving license in the world) (only PADI can, and the training qualifications of other diving institutions are not yet available). And when you have a diving card, you will find that the blue sea will be more attractive to you. During your diving trip, you may meet diving friends from all over the world at any time. The same diving culture between you will make you more open-minded and open-minded, and be so close to the sea, which will also play an excellent role in shaping your's character.

Diving can reduce weight.

The environment of water is very different from that of land. Studies have proved that people's resistance in water is more than 800 times that in air. The great resistance brought by water will increase the difficulty and total amount of exercise, so that you can complete an action with more than 6 times the usual strength, thus achieving twice the result with half the effort. On the other hand, the thermal conductivity of water environment is more than 20 times that of air, even if it is still in water, it will consume a lot of energy. Like a boiling egg, it cools much faster in water than in air. Therefore, the energy consumed by a person exercising in water for 10 minutes is equivalent to exercising on the ground with the same intensity for more than 1 hour. Exercise in water for 40 minutes can consume 400 calories, which can easily achieve the purpose of exercising the whole body. In addition, when people move on land, there is a lot of close friction between joints due to gravity, which is easy to cause sports injuries.

In water, it is almost in zero gravity state, which greatly reduces the pressure on joints, bones and muscles, makes them less likely to be injured and reduces the pain of exercise. The buoyancy of water can also improve flexibility and make the movements of all joints of the body more flexible. Sports that can't be done on land, including muscles that can't be practiced, can be easily won in water. By imitating the swimming posture of fish, all parts of the body are stretched evenly, and the fitness effect is excellent. Fitness, diving is definitely the best choice. In addition, frequent abdominal tummies are good for losing weight. When we dive into the water, the pressure of the water will naturally make us reach the state of abdomen, so that we can lose weight unconsciously. So most people who often dive are in good shape.

Diving can beautify the skin.

In fact, diving has a unique beauty massage effect on people. People basically do not sweat when they exercise in water, which reduces the stimulation of salt in sweat to the skin. At the same time, the skin turns red and hot after being slapped by water and waves, which dilates capillaries, improves the circulation function of subcutaneous blood vessels, and has a special massage function, which can reduce the relaxation and aging of the skin and make the skin smooth, smooth and elastic.

The pure air compressed into bottles by leisure divers after multi-stage purification is equal to? Wash? Suffering from lung disease; Diving has always been very popular in Japanese MM, because when diving, with the increase of depth, people will inhale more and more pure oxygen according to the law of gas partial pressure. Hyperoxia can eliminate distractions, relieve stress, relax, cultivate the mind, restore fatigue and reduce skin wrinkles. The beauty effect is obvious!

Diving has the health effect of reducing pressure and preventing cancer.

Diving can exercise people's physique, promote the improvement of the functions of human tissues and organs, especially have a good effect on the respiratory system and cardiovascular system, can alleviate the pain of patients with varicose veins, and is also conducive to improving the sleep of people with excessive fatigue and insomnia. Moreover, diving can also improve and improve the cardiopulmonary function of the human body. At the same time, it is found that people who are in frequent contact with seawater can effectively supplement the trace elements that the human body lacks by salinizing the minerals in seawater into ions. In the United States and Japan, diving is even used as an auxiliary means to treat cancer. According to scientific proof, the balanced pressure of water on human body can promote blood circulation, and long-term balanced oxygen inhalation under water can effectively kill cancer cells and inhibit their spread.

Diving can also promote family harmony.

For families who go diving together, another advantage is that they can cultivate their children's good quality of being helpful. When your child gets the diving certificate, he (she) will become a potential partner of his/her father or mother. Potential family partners can encourage each other and improve their diving skills through practice. As long as you have the same interests, you can expand the scope of diving spots, enjoy underwater fun and share it as a precious memory of life. The relationship between family members can therefore be well maintained and promoted. At the same time, it is also a good opportunity to cultivate children's awareness of marine environmental protection, and it is also of great significance to children's world outlook and outlook on life education.
