Matters needing attention in bathing in summer
1 and 40℃ are important boundaries, so cardiovascular patients should be cautious.
When the water temperature exceeds 40℃, the stimulation of the temperature to the body will be strengthened and the sympathetic nerve will play a role. Its function is to get the body and mind excited. For people with chronic diseases such as hypertension, arteriosclerosis and coronary heart disease, it is a dangerous behavior that the water temperature is too high when bathing. With hot water washing, the capillaries of the whole body dilate, and a large amount of blood dilates the blood vessels on the body surface, and the blood of important organs such as the heart and brain is relatively reduced, which may lead to accidents such as myocardial infarction.
2. How long it takes to soak depends on the water temperature.
Bathing time depends on the water temperature, especially for people in poor health. Many people can't soak in hot water above 40℃ for a long time. Soak at water temperature above 42℃ for 3-5 minutes, at 40℃ 10 minute, and at 37℃ to 39℃ for 20-30 minutes.
3. Be wary of taking a bath after drinking
Drink some wine and take a hot bath. That sounds beautiful. In fact, it is easy to cause cardiovascular disease. Cardiovascular experts believe that after drinking, due to the accelerated blood circulation, the glucose stored in the body will be consumed in large quantities during bathing, resulting in a rapid drop in body temperature. At the same time, alcohol inhibits the normal physiological activities of the liver and hinders the recovery of glucose storage in the body, which is easy to lead to shock and can be fatal in severe cases. Therefore, Dr. Wang also reminded everyone that it is best not to take a bath immediately after drinking. "Some people mistakenly think that taking a hot bath can relieve alcohol, but in fact it will only aggravate heart ischemia." When you have dizziness, chest tightness, dizziness and other "bathhouse syndrome" during bathing, you should also stop bathing immediately and go to the hospital for treatment.
4. Take a bath to prevent "heatstroke"
Heatstroke is a disease characterized by dysfunction of thermoregulation center and disorder of water and electrolyte caused by high temperature. Many people think that heatstroke will only happen in the summer when the sun is shining, but bathing in winter may also happen. It is very cold in winter, and many people like to take a bath. In public bathrooms, if you take a bath for too long, you will feel chest tightness, shortness of breath, dizziness and even syncope.
