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. ]PH*J！ X4p 'y But not everyone can steam in the sauna, 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.

When they come out of the sauna, their heavy bodies suddenly become relaxed and their spirits relax, which is also an important reason why people like this leisure way. UX * O \} K 14 TVZO 8 $ {F It is known that when people are in the sauna, they are exposed to continuous high-temperature fog and steam. 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 the health care functions of dredging blood vessels, relaxing nerves and eliminating fatigue. At the same time, it can also accelerate skin metabolism and enhance skin elasticity and smoothness. k ' D & ampk)= 8f； Not everyone can steam U0mry &；; A) Guo Lijun, deputy director of the Department of Cardiology of the Third Hospital of Beijing Medical University, told the reporter that the sauna also depends on people's physical condition. People with poor heart function, cardiomyopathy or congenital heart disease can't take a sauna. There are also 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 family history of diabetes, obesity and heart disease.

Guo Lijun said: "Environment, weather, seasons and changes in air pressure are all inducing factors for cardiovascular and cerebrovascular diseases." 7dm}([m} Dj4S|N"K]m According to her, people who have washed the sauna have this experience, and they will soon feel out of breath after being surrounded by hot steam. 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 air in the room drops, even healthy people will feel chest tightness and shortness of breath, not to mention those special people. {$JG#eG？ Bw{a0=Vl) ` 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 skin 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 excitation, increased heart rate, coronary artery contraction, increased myocardial oxygen consumption and increased cardiac workload, which makes the already fragile heart more overwhelmed. stK & lt% p+m \ & amp； @h5:fPU In addition, in the sauna room, people sweat a lot, and the blood becomes sticky, which is easy to form blood clots, leading to various cardiovascular diseases. Especially for the elderly, their thermoregulatory center is not very sensitive, so it is not suitable for sauna. Fxgrih4u/@/# 0Also, 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.
