Some data show that hot spring bath can not only relax muscles and joints, but also eliminate fatigue; It can also dilate blood vessels, promote blood circulation and accelerate human metabolism. In addition, most hot springs are rich in chemicals, which are helpful to the human body. For example, calcium carbonate in hot springs plays a considerable role in improving physical fitness and restoring physical strength; Hot springs are rich in calcium, potassium, radon and other ingredients, which have certain curative effects on regulating cardiovascular and cerebrovascular diseases and treating diabetes, gout, neuralgia and arthritis. Sulfur spring can soften cutin, and carbonated water containing sodium can bleach and soften skin. Long-term persistence in soaking in hot springs According to the relevant person in charge of the Southern Hot Springs, it is unrealistic to soak in hot springs once or twice on holidays to achieve the purpose of health or beauty, and it must be adhered to for a long time to be effective. The reporter interviewed a female tourist in Tianci Hot Spring. She said that she would bring her parents and children to the hot springs at least two or three times a week. She believes that women often go to hot springs for beauty, which is better than using any brand-name cosmetics. She also believes that hot springs should be kept for a long time. She pointed out that she used to be overweight, and the effect of losing weight by various methods was not obvious. Since she insisted on soaking in hot springs every week, she found that her figure was getting better and better. She also told reporters that her father had suffered from scapulohumeral periarthritis. After three months of long-term adherence to hot spring bath, his symptoms are much better now. Hot springs are not for everyone. Although hot springs have various health benefits, they are not suitable for everyone. Experts remind that patients with hypertension and heart disease can soak in hot springs on the premise of taking medicine regularly, but it is best not to exceed 20 minutes at a time. When you get up, you should be careful and slow to prevent dizziness and fall down due to vasodilation and blood pressure drop. Sulfur and other acid and alkali substances contained in hot springs can diminish inflammation and sterilize, which is very effective for general infectious or parasitic skin diseases, but sometimes it can irritate the skin, worsen the wound and even lead to "hot spring skin diseases". Therefore, for some patients with skin diseases, it is not appropriate to soak in hot springs. For people with eczema and atopic dermatitis, soaking in hot water for too long will accelerate the evaporation of skin moisture, destroy the protective layer of skin and easily lead to the aggravation of symptoms. Soaking in hot springs seems simple, but not everyone knows how to soak scientifically. A staff member of Cimushan Hot Spring told the reporter that when soaking in the hot spring, you should try to close your eyes and take a few deep breaths slowly in a meditative mood, so as to really release the physical and mental stress. Moreover, soaking in hot springs should not start from a pool with high water temperature, but from a pool with mild water temperature; Soak in hot pool water for no more than 10 minute each time, and let the upper chest come out or rest in time; Do not soak in the water level above the chest for more than 10 minutes. Soak alternately with mild pool water in time or soak and rest in time after the body comes out. Hot spring temperature is high, and after soaking, there will be discomfort such as sweating, dry mouth and chest tightness, which is a normal reaction of excessive blood circulation. At this time, soak in cold water or rest in water for a short time, and drink plenty of water to relieve it. In addition, experts remind that patients with heart disease and hypertension should soak in water together, and if they are uncomfortable, they should rest in the water immediately; Don't soak when you are hungry, because an empty stomach can easily lead to fatigue, so you must take a nap or have a rest after meals before soaking; After drinking, you must sleep and rest before soaking, otherwise bathing will stimulate blood circulation, leading to physical exhaustion and fear of accidents; Tired from a long journey, don't suddenly enter the hot spring, take a break and take a dip after your physical strength recovers; After soaking in the hot spring, the human body's water evaporates quickly, so remember to drink water in time.
