Sweating is good for human metabolism.
Sweating is a normal physiological function of human body and an important link to keep body temperature constant. There are about 3.3 million sweat glands on human skin, from which sweat is secreted. Its main component is water, followed by urea and a small amount of metal ions, lactic acid, chlorine compounds, potassium, sodium and some metabolites produced by metabolism.
Normal people will probably evaporate 600-700 ml of sweat a day. External temperature, mental stress, emotional excitement, eating spicy or hot food will make people sweat. If the function of sweat glands is abnormal, when the human body is in a state of high fever, it can not play the role of sweating normally, and the human body will have high fever, which will cause damage to the heart, brain, liver, kidney and blood system. In addition, sweat glands also have antibacterial, moisturizing skin and maintaining electrolyte balance in the body.
Traditional Chinese medicine believes that the production of sweat has a certain relationship with viscera. Excessive sweating will consume blood and harm body fluids. On the other hand, if the body fluid is deficient and the source of sweat is insufficient, it is not appropriate to sweat. Sweating is the most effective way to detoxify. Sweating more in summer all year round is beneficial to human metabolism, meridian balance and the health of immune system. If you don't sweat for a long time, it will cause the disorder of human metabolic system.
Abnormal sweating is related to disease.
Traditional Chinese medicine divides abnormal sweating into spontaneous sweating, night sweating, heart sweating, axillary sweating and other types, and is also regarded as a "barometer" of human health.
Spontaneous sweating: sweating often during the day and more after activities, which is called spontaneous sweating. Long-term illness, weakness, easy to catch a cold, pale and bloodless, belonging to qi deficiency and spontaneous sweating, the cause is mainly in the heart and lungs; Spontaneous sweating accompanied by chills and limb temperature belongs to spontaneous sweating due to yang deficiency, which is mostly caused by deficiency of Yang Qi of spleen and kidney. Those who suffer from spontaneous sweating due to qi deficiency should exercise moderately, keep warm alternately in four seasons, and drink astragalus water every day to replenish qi; People who are sweating due to yang deficiency should avoid eating cold and frozen products, such as grapefruit, pear, kelp, shrimp and crab.
Night sweats: Sweat after falling asleep and stop after waking up. Accompanied by low fever in the afternoon, flushing on cheeks, fever in hands and feet, and emaciation, it belongs to night sweats caused by yin deficiency and internal heat, which are generally common in those who are suffering from yin deficiency and fire, especially tuberculosis patients. It is recommended to drink lily porridge, wolfberry porridge, tremella lotus seed soup and old duck soup.
Half-body sweating: half-body sweating, the other half not sweating or slightly sweating. In this case, the lesion is on the anhidrosis side, and phlegm and dampness block the meridians on one side of the body, so that qi and blood can not run, and the transport of body fluid is blocked, resulting in sweat excretion disorder. This kind of people should avoid "fat, sweet and thick" in their daily diet, otherwise it is not conducive to the transport of spleen, and abnormal sweating will be aggravated.
Heart sweat: Hyperhidrosis between the heart socket and the breasts is mostly due to excessive thinking and sadness of the heart and spleen. Sweating patients can do abdominal massage half an hour after meals: stick the palm root on the abdomen with the navel as the center, massage from the inside out, 30 times per minute, 10- 15 minutes.
Sweating under the armpit: sweating under the armpit or even under the ribs. Sweating is not smelly, accompanied by dreaminess, irritability and insomnia, dizziness and fatigue, fever in the afternoon or fever in hands and feet, mostly due to liver heat and yin deficiency; Accompanied by chest tightness, aversion to diet and scanty urine, it belongs to damp-heat in the liver and gallbladder. It is suggested that such people eat foods that can dispel dampness, such as lotus seeds, broad beans, wax gourd and bitter gourd.
Sweating on hands and feet: sweating on palms, accompanied by loss of appetite, weight, yellow urine, greasy tongue coating, etc., belonging to spleen and stomach dampness; If accompanied by shortness of breath and loss of appetite, it belongs to spleen and stomach qi deficiency; If accompanied by dry throat and hunger, it belongs to spleen and stomach yin deficiency. Sweating hands and feet suggests eating yam to nourish stomach yin.
