Using far-infrared light wave bath room will cause a series of systemic physiological changes. High temperature and high humidity make the heart beat faster and blood pressure rise to a certain extent, while soaking in cold water will slow down the heart beat and lower blood pressure. Therefore, indoor temperature, humidity and bathing time, including the number of cold and hot exchanges, must be strictly controlled. When taking a shower for the first time, you can only stay in the high-temperature steam room for 5 minutes, and then gradually extend the stay time in the high-humidity steam room. Due to the influence of sauna on human body, it is not appropriate to use light wave bath room in the following circumstances:

1, patients with previous hypertension and heart disease history. Because steaming the far-infrared light wave bath room leads to a wide range of blood pressure fluctuations, which increases the heart load and is easy to cause hypertension, heart disease, accidents and even life-threatening.

2. After a meal, especially within half an hour after a full meal. Washing the far-infrared light wave bath room immediately after meals will dilate the skin blood vessels, and a large amount of blood will flow back to the skin, affecting the blood supply of digestive organs, which will inevitably affect the digestion and absorption of food and be harmful to health.

3. When you are overworked or hungry. When people are tired and hungry, their muscle tension is poor, and their tolerance to cold and hot stimuli is reduced, which is easy to cause collapse.
