Since the beginning of summer, many saunas across the country have launched the "Summer Sweat Steaming Detoxification and Beauty Preservation" project, attracting a large number of consumers. However, recently there has been an increasing number of patients seeking treatment in major hospitals due to excessive sweating, including cases of dehydration caused by continuous sweating for several hours. Experts remind that sweating appropriately in summer is beneficial to health, but do not blindly pursue "sweating profusely". A week ago, Ms. Wang experienced dizziness and palpitations after sweating in the sauna for more than 8 hours for three consecutive days. Examination showed that her sodium ion concentration was significantly lower than normal. Coincidentally, Mr. Ma, a resident of Harbin, suddenly fainted after sweating continuously for several hours in the sauna. When he was taken to the hospital, his blood pressure dropped to 80/50mmHg, and he was diagnosed with "severe dehydration combined with electrolyte imbalance". Moderate sweating in summer is indeed beneficial to health, but excessive sweating can have the opposite effect. ”Liu Ping, Deputy Chief Physician of the Nursing Outpatient Department of Integrated Traditional Chinese and Western Medicine at Heilongjiang Provincial Hospital, said. Sweating can moisturize the skin, keep pores open, help eliminate waste from the body, relax tendons and unblock meridians, and promote smooth blood flow. In addition, studies have found that antimicrobial peptides contained in sweat can effectively resist viruses, bacteria, and fungi. Moderate sweating can also stabilize blood pressure. Sweating during exercise helps to dilate capillaries, accelerate blood circulation, increase vascular wall elasticity, and thus achieve the goal of lowering blood pressure, "said Liu Ping. Liu Ping said that the traditional Chinese medicine "sweating method" emphasizes "slight sweating", such as oral decoctions, moxibustion, massage and other methods can achieve the purpose of sweating and dispelling evil, and generally do not make people sweat profusely. On the contrary, if one sweats excessively, the body's water loss accelerates. If not replenished in a timely manner, they may fall into a state of dehydration, causing dryness of the tongue, short and yellow urine, fatigue, palpitations, shortness of breath, and an increased risk of blood clots. Liu Ping further explained that 99% of sweat is water, and the remaining 1% contains electrolytes such as sodium, potassium, and chlorine. Excessive sweating can cause dehydration, which can increase blood viscosity and slow down blood flow. This is similar to how the water flow in a river slows down and sediment is easily deposited. Impurities in the blood can also accumulate in the blood vessels, thereby increasing the risk of thrombosis. At the same time, sweat can take away a large amount of electrolytes such as sodium and potassium. Once the body's electrolytes are imbalanced, it can affect nerve and muscle function, and symptoms such as nausea, fatigue, muscle spasms, limb numbness and pain may occur. Liu Ping stated that excessive sweating and failure to replenish electrolytes in a timely manner for more than 6 hours may lead to hyponatremia, headaches, vomiting, blurred consciousness, and in severe cases, brain edema. Be alert to four types of abnormal sweating. Excessive sweating is not conducive to health. In fact, the following abnormal sweating situations are also the body sounding a health alarm. One is night sweats, which means sweating while sleeping and stopping when waking up. Night sweats are often accompanied by symptoms such as insomnia, dry throat, and restlessness. Western medicine believes that this condition is usually caused by increased sympathetic nervous system excitability at night, mental stress, or certain diseases. Traditional Chinese medicine believes that this is related to yin deficiency. The second type is half body sweating, also known as partial sweating, which is manifested as sweating on the upper body but not on the lower body, or sweating on the left body but not on the right body. This situation may be caused by autonomic nervous system disorders. The third is cold sweating, which is mainly manifested as chills, lack of energy, pale complexion, cold sweating on limbs, etc. This situation usually occurs after being frightened, panicked, or in shock. People who frequently break out in cold sweat may also experience symptoms such as fear of cold, dizziness, hunger, and palpitations. Common causes include hypoglycemia, autonomic nervous system disorders, endocrine disorders, and cardiovascular problems, which need to be judged based on specific symptoms. The fourth is excessive sweating. The so-called excessive sweating refers to the frequent sweating of the whole body or certain parts beyond the normal range in a quiet state or daily environment. Once excessive sweating occurs, it is necessary to check for conditions such as hyperhidrosis, hyperthyroidism, menopausal syndrome, etc. Liu Ping reminds that these abnormal sweating situations may be a warning from the body. If you encounter these situations, it is recommended to seek medical examination in a timely manner. (New Society)
