The use of far-infrared sauna can cause a series of systemic physiological changes. The high temperature and high humidity environment accelerates the heart rate and increases the blood pressure to a certain extent, while the cold water immersion will slow down the heart rate and decrease the blood pressure. Therefore, it is necessary to strictly grasp the indoor temperature, humidity and bath time, including the number of hot and cold exchange. When entering the bath for the first time, the high-temperature steam room can only stay for 5 minutes, and then gradually extend the residence time in the high-humidity steam room. Because the sauna has a certain impact on the human body, it is not appropriate to use the far-infrared sauna under the following circumstances:
1. Patients with a history of hypertension and heart disease. Because steaming far-infrared sauna causes a wide range of blood pressure fluctuations, increase the heart load, easy to cause high blood pressure, heart attacks, accidents and even life-threatening.
2, after meals, especially within half an hour after a full meal. Wash the far-infrared sauna immediately after a meal, the skin blood vessels dilate, a large amount of blood back to the skin, affecting the blood supply of the digestive organs, is bound to affect the digestion and absorption of food, which is not good for health.
3. When overworked or hungry. When tired and hungry, the body muscle tension is poor, the tolerance of cold and heat stimulation is reduced, easy to cause collapse.
