Diving is beneficial to shaping people's body and mind in all aspects: the benefits of diving are not only that the fantasy world in 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 brave, tenacious, cooperative and cautious will, 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 a qualified diver, 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.
Diving has the function of losing weight: the environment in water is very different from that on land. Studies have proved that people's activity 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.
Diving has the function of beautifying 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.
Leisure divers use pure air compressed into bottles after multistage purification, which is equivalent to "washing the lungs" for urbanites suffering from air pollution; 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 care function of decompression and anticancer: diving can exercise people's physique, promote the improvement of the functions of various tissues and organs of the human body, especially has 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 it can cultivate 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.
