Prevention and treatment of obesity
Due to the improvement of life, there are more and more obese middle-aged and elderly people, but the effect of using diet tea and diet pills is not good. I suggest you take an active part in swimming activities and achieve ideal results. Swimming is a whole-body exercise. Coupled with the friction of water on the human body surface, it can accelerate the blood circulation of capillaries, enhance metabolism, accelerate the consumption of fat, promote the muscle development of limbs, chest and abdomen, waist and back, enhance the function of internal organs, improve the disease resistance of human body, and easily and happily realize the harmonious unity of weight loss and bodybuilding.
Prevention and treatment of arthritis
Including rheumatoid arthritis, rheumatoid arthritis, traumatic arthritis and other types, are very suitable for swimming physiotherapy. When arthritis patients swim in the water, the water will produce a mechanical stress on human joints, which will play a good massage role and relax the stiff joints. At the same time, when swimming, the knee joint and ankle joint don't need to exert continuous force as when running or walking, so that each joint can relax and rest, which is helpful to the regression of inflammation and functional rehabilitation.
Prevention and treatment of asthma
Swimming in the water is the most suitable natural environment for asthma patients, because there are almost no dust and other substances that cause respiratory allergies in the water surface and nearby air. In addition, regular swimming exercise can increase vital capacity and improve the respiratory function of the lungs, which is quite beneficial to the prevention and treatment of asthma.
Prevention and treatment of varicose veins
When swimming, because the lower limbs keep flexing, pedaling or pedaling in the water, it can increase the tension of leg muscles, massage venous vessels, promote venous blood return, and eliminate congestion and swelling, thus playing a role in treating or preventing varicose veins.
Prevention and treatment of insomnia or neurasthenia
Especially for mental workers, insomnia or neurasthenia caused by excessive brain use and insufficient physical activity can receive immediate results through swimming exercise. Because swimming is a whole-body exercise, it can accelerate the whole body to vomit the old and absorb the new, improve the functions of brain nerve, blood circulation, breathing, digestion and excretion, and internal organs, especially regulate the excitement and inhibition of the central nervous system to restore its balance, so that patients with insomnia or neurasthenia can get better curative effect quickly.
It is good for the spine, because: swimming supine posture reduces the weight of internal organs and the burden on the heart, and more importantly, the buoyancy of water offsets the oppression of gravity on internal organs to the greatest extent, so that internal organs can be fully relieved; At the same time, the limbs and all their joints are fully stretched, which is very beneficial to physical development and health, which is impossible for all other sports. Especially the full extension of the spine has a miraculous effect on the prevention and treatment of cervical and lumbar diseases. Experts say that swimming is the best treatment for spinal diseases. But be careful not to practice too hard and gradually increase the amount of exercise. If you are injured, you should recover before going into the water.
However, swimming for a long time is bad for your health.
Swimming for a long time is not good for your health.
Swimming in water for a long time, especially in very cold water, is not necessarily good for your health.
Because water is a good conductor of heat, the human body is easy to dissipate heat in water. In order to avoid excessive heat loss, skin blood vessels will produce protective reflex, which will make skin blood vessels contract. So as soon as you enter the water, your skin becomes pale. After swimming in the water for a period of time, muscle activity makes skin blood vessels dilate, blood circulation accelerates, heat increases, skin turns from white to red, and the body feels a little warm. At this time, people can maintain activities in the water for a period of time.
If you stay in the water for a long time, the heat generated by your body is lower than that dissipated in the water, and your thermoregulation function is destroyed. At this time, the middle artery of the skin will contract and the venules will expand, so that the blood will stagnate in the subcutaneous vein, resulting in blue skin, black lips, "goose bumps" and even convulsions.
In this case, you must go ashore immediately, dry the water on your body, bask in the sun, and get dressed as soon as possible after warming up to prevent colds, tachycardia, muscle strain and other diseases.
