There are many hot springs, big and small, and many so-called "fake hot springs". Not only "a hot spring" has health care function. There are only hot springs with a certain concentration of minerals (soluble solids per liter of water 1g or more) and special gases (such as carbon dioxide, hydrogen sulfide, radon, etc.). ) and a certain amount of chemical components (such as iron, bromine, fluorine, etc. ) can have a health care effect on the human body.

Some "fake hot springs" come from mountain springs or groundwater. Hot spring water boiled with this water source may also be rich in minerals and have certain health care effects. Of course, the content and composition of minerals in water should also be analyzed. Other hotels simply boil tap water as hot spring water. This fake hot spring has no health care function, just taking a warm bath can relieve stress and fatigue at most.

Taboo 2: The longer the soaking time, the better the health care effect?

Chen Xiuhua said you shouldn't spend too long in hot springs. How long it takes depends on the temperature of water. 34℃~36℃ is a mild bath, which has an inhibitory effect on the central nervous system and can calm the mood. 37℃~38℃ is a warm bath, which can relieve vasospasm, promote blood circulation and eliminate skin tension; 39℃~42℃ is a high temperature bath, which can improve blood circulation and promote metabolism. The time for each hot spring bath is 10~20 minutes. If the micro-temperature bath time of 34℃~36℃ is long, the high-temperature bath must not be too long.

Because of the different composition of hot springs, the duration of soaking should be different. If the main component of the hot spring is carbonic acid, it is necessary to prevent the adverse reaction caused by excessive inhalation of carbonic acid gas, so you should take a bath or rest every other day 1 day for 2 consecutive days, 8~ 15 minutes each time.

Taboo 3: Not all cold bubbles are good.

In addition, there are many kinds of hot springs, and indeed different bathing methods will also affect their efficacy. Chen Xiuhua said that waterfall bath can exercise muscles and relieve soreness, while sitz bath can eliminate fatigue. Hot and cold alternating hot springs can accelerate the relaxation of the whole body, so people often alternate hot springs and cold water.

However, soaking in hot water before soaking in cold water is absolutely forbidden for people with angiosclerosis or hemangioma, especially when the temperature difference is too large, and it is not suitable for soaking for a short time. This practice is more likely to cause a cold for people with weak constitution. Because blood vessels dilate and pores relax during hot water soaking, it is easy to cause cold evil to take advantage of it. In addition, it is worth reminding that this method is easy to cause sudden expansion or contraction of human blood vessels, suffering from hypertension, coronary heart disease and so on.

Many people think that they have caught a cold, and soaking in hot springs can use the temperature of hot springs to help them recover. Is that so? Chen Xiuhua said that if the symptoms of your cold are stuffy nose, loss of appetite, fullness and fullness, soaking in hot springs does have a certain rehabilitation effect. However, if you are prone to fatigue, shortness of breath and asthma during exercise, it belongs to qi deficiency and is not suitable for hot springs.

Taboo 4: Taking a bath after drinking is easy to get dizzy.

When traveling in hot spring resorts, some people go to hot springs after drinking, but it is not appropriate. Because the warm effect of hot springs will make the heart beat faster, blood pressure rise, the heart load is too heavy, and there is less blood in the brain when standing. Drinking too much can easily lead to dizziness and falls.

This problem also exists after satiety. The heat of hot springs will stimulate the blood to concentrate on the skin surface, inhibit the digestion and absorption function of the human body and inhibit the appetite center. Therefore, Chen Xiuhua advised people not to soak in hot springs 30 minutes before meals and 1 hour after meals.
