Is there anything special about the sauna? Is there a priority between dry steaming and wet steaming?

Modern people are very busy at work and life, so it's good to go to the sauna occasionally to "steam", which can relieve stress and relax nerves, and is also very good for the body. ?

However, not everyone can steam in the sauna room, especially some patients with cardiovascular and cerebrovascular diseases or potential diseases. If they are not careful, they may get into big trouble. Recently, there have been frequent reports of diseases such as myocardial infarction caused by sauna, which shows that sauna also varies from person to person. ?

Sauna accelerates blood circulation, which is beneficial to eliminate toxins in the body. Many people have this experience. After coming out of the sauna, the original heavy body became relaxed and the spirit relaxed a lot, which is also an important reason why people like this leisure way. ?

It is understood that people are exposed to continuous high-temperature fog and steam during sauna. Through a lot of perspiration and heat dissipation, skin capillaries are fully expanded, blood circulation is accelerated, tissues and cells in the body get more oxygen and nutrition, and excessive fat waste and lactic acid accumulated in the body are quickly excreted. Therefore, sauna has health care functions such as dredging blood vessels, relaxing nerves and eliminating fatigue. At the same time, it can also accelerate skin metabolism and enhance skin elasticity and smoothness. ?

Sauna also depends on people's physical condition. People with poor heart function, cardiomyopathy or congenital heart disease are not allowed to take a sauna. Patients with cardiovascular diseases or asymptomatic potential patients, including chronic diseases such as coronary heart disease, hypertension, hyperlipidemia, hyperglycemia and high blood viscosity, as well as people with diabetes, obesity and family history of heart disease, are not suitable. ?

"The root cause of cardiovascular and cerebrovascular diseases is the contradiction between supply and demand of blood supply." Guo Lijun said: "Environment, weather, seasons and changes in air pressure are all inducing factors for cardiovascular and cerebrovascular diseases." ?

Anyone who has washed a sauna has the experience that being surrounded by hot steam will soon feel out of breath. This is because the sauna room generally has a small space and high air humidity, and there is no window for air circulation. When the oxygen content in the indoor air drops, even healthy people will feel chest tightness and shortness of breath, let alone those special people. ?

Moreover, the temperature of sauna room usually exceeds 40℃. In such a high temperature environment, the metabolism of the human body will be obviously accelerated, the blood vessels under the human body will expand, the blood flow of the skin will increase by 3-5 times than usual, and the blood flow back to the heart will also increase obviously, which will inevitably increase the burden on the heart. ?

At the same time, high temperature can cause internal environment disorder, sympathetic nerve excitement, accelerated heart rate, coronary artery contraction, increased myocardial oxygen consumption and increased cardiac workload, which makes the already fragile heart more overwhelmed. ?

In addition, in the sauna room, people sweat a lot, and the blood will become sticky, which is easy to form thrombus and lead to various cardiovascular diseases. Especially for the elderly, their thermoregulatory center is not very sensitive, so it is not suitable for sauna. ?

In addition, don't take a sauna when you are overworked or hungry. When people are tired or hungry, their muscle tension is poor, their tolerance to hot and cold stimuli is reduced, and it is easy to cause collapse when taking a sauna. ?

According to a foreign study, the high temperature environment has great damage to the growth of male sperm, so unmarried men should not wash the sauna too often, otherwise it will easily lead to infertility. ?

When taking a sauna, people can go together. Pay attention to timely hydration before and during steaming. Don't wait until you are thirsty to drink water. You can also carry a bottle of water with you to replenish water at any time. ?

Once you feel chest tightness or other uncomfortable feelings, leave the sauna immediately, lie flat in a well-ventilated place and drink some cold boiled water (be careful not to drink water with too low temperature).
