I want to know the efficacy of sauna, Finnish sauna and far infrared sauna.

Sauna, also known as Finnish bath, refers to the process of physical therapy with steam in a closed room. Usually, the indoor temperature of sauna can reach above 90℃. Sauna originated in Finland and has a history of more than 2000 years. By using the cold and hot stimulation of repeated dry steaming and water washing, blood vessels can be repeatedly expanded and contracted, which can enhance the elasticity of blood vessels and prevent arteriosclerosis. It has a certain health care effect on arthritis, low back pain, bronchitis and neurasthenia.

Sauna is a fashionable and healthy leisure way. After sweating all over, the whole body is relaxed and tired, so many people who are nervous at work are quite good at it. However, medical experts warn that frequent sauna may become the chief culprit of male infertility. In Finland, the birthplace of sauna, the incidence of male infertility is quite high, which is not unrelated to the local people's love for sauna. The temperature of infertile testis caused by frequent sauna is generally 3-4℃ lower than that of human body, so that normal sperm can be produced. Sperm has strict requirements on temperature and must develop normally at a low body temperature, while the temperature in sauna is much higher than body temperature, which is not conducive to sperm growth, or leads to excessive decline of sperm vitality and infertility. According to clinical statistics, a considerable number of male infertility patients are caused by the testicular temperature being higher than the normal temperature. Reminder: For unmarried and childless men, besides sauna, other factors that can increase testicular temperature should be avoided as far as possible, such as riding a bicycle for a long time, taking a hot bath, sitting for a long time, wearing tight jeans and so on.

Sauna can 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. Because sauna has certain influence on human body, the following conditions are not suitable for sauna: 1, patients with previous history of hypertension and heart disease. Because sauna makes blood pressure fluctuate in a wide range, it increases the heart load, which is easy to cause high blood pressure, heart attack, accidents and even life-threatening. 2. After a meal, especially within half an hour after a full meal. Taking a sauna immediately after a meal will dilate the blood vessels of the skin, and a large amount of blood will flow back to the skin, which will affect 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. [4] It is not easy to wash the sauna after fatigue. 4. It is best for menstrual women to avoid sauna. Menstrual women's physical resistance is reduced. When taking a sauna, cold and heat alternate many times, which is easy to cause colds and bacterial infections and endanger women's health. Of course, this doesn't mean that you shouldn't take a sauna. You can also take a shower once in a while. If you have given birth to a child, you can enjoy it. Sauna still has a certain health care effect on human body: it can speed up blood circulation, completely relax muscles in all parts of the body, and achieve the purpose of eliminating fatigue and restoring vitality. At the same time, due to repeated hot and cold steaming and washing of the body, blood vessels continue to contract and expand, which can enhance the elasticity of blood vessels and prevent arteriosclerosis. At the same time, it has a certain health care effect on arthritis, lumbago, bronchitis and neurasthenia.

The room temperature is usually adjusted between 50 degrees Celsius and 80 degrees Celsius, and the humidity stipulates that one cubic meter of air contains 50 to 60 grams of water vapor. In order to adjust humidity and ventilation, the steam roof must be equipped with small windows that can be opened and closed. The first step in the Finnish bath is to take a shower, and then enter the steam room naked (except for private saunas, all saunas in Finland are arranged for men and women to use separately, and towels are only used as cushions). When enjoying the hot steam bath, bathers beat their bodies with soft birch branches and leaves, so that blood runs faster, skin pores are opened as much as possible, and sweat flows out of the body more smoothly. After sweating for a period of time, people who take a bath should take a bath first, clean themselves and cool down (for example, the sauna is located by the lake, or in cold winter, people simply jump into the ice pool dug by the lake or snow), and then return to the steam room to beat and sweat after the hot air dissipates, and then return to the water to cool down. After going back and forth several times, the dirt in the body is discharged and people are fully relaxed. Finally, after thorough cleaning, the Finnish bath is completed. Be sure to eat some high-salt food after taking a bath to supplement the salt lost by your body.
