Diving is very popular with everyone. What are its advantages and disadvantages?

Improve manpower and operational flexibility. In the process of snorkeling, you must move and bear higher friction resistance than the ground. The more you dive or swim, the better your muscle tissue will be, and at the same time, you can improve your physical strength and flexibility. Lower your blood pressure. If you dive for the first time, your heart rate will increase and your blood pressure may rise slightly, which is probably just because you are too excited. In fact, for most deep dives, when the human body is in water below its basal body temperature, the capillaries on the surface of the human body will gather to store heat for the human body, and everyone's heartbeat and blood pressure will decrease.

Improve your health. Constant leg movement in potential water can help maintain and improve your health. You can also broaden your horizons and dive in cold areas. You can choose the indoor diving industry base for deep diving. It must be reminded that soaking in water for a long time is likely to dry our bodies, so we should replenish water immediately after deep diving. Interact with marine animals. This may be the motivation for many deep divers to get hooked on this fitness sport at first. If you dive deep and are surrounded by marine animals, are you full of excitement, surprise and awe? All kinds of fish, coral reefs and microorganisms, which you have never seen on the ground, can improve everyone's satisfaction.

Exposure, although we all know that exposure can cause vitamin D, vitamin D is not only beneficial to the digestion and absorption of calcium, but also beneficial to the transfer of calcium between somatic cells. This high digestibility of calcium is conducive to maintaining the physical and mental health and strength of human bones. Relieve stress When we inhale, people tend to inhale slowly and deeply during the whole snorkeling process, just like we inhale during meditation training. When diving freely in the water to enjoy the natural environment, the slow breathing system will create a quiet situation. Things that may happen in daily life, including; Work problems, family conflicts and money problems are all forgotten. In deep diving, all the problems were forgotten. At the same time, there are actually some risks. Besides, the lake where everyone lives has Xiangjiang River on one side and Chishui River on the other. Their common feature is water flow, and the water in the middle is more and more urgent, especially in some intelligent backwater sections. If you dive too deep, it's easy to lose control. If you are not careful, you are prone to accidents.

Deep diving is worried about abnormalities when it meets the human body. Most of the abnormalities mentioned here refer to calf cramps, which is also the most troublesome thing in swimming. Human work stress: it is the source of work stress that harms human body and leads to discomfort and fatigue. Even a slight discomfort can lead to work stress, and if you don't pay attention, it is likely to lead to obvious problems. Free diving can't feel forced to dive deep or exceed one's physical limit, in case of accumulating too much work pressure.
