Tidal sweating refers to the secretion of sweat by the sweat glands. There are two types of sweating, one is normal sweating and the other is abnormal sweating. The abnormal sweating may be a result of the body’s defensive Qi not being consolidated, leading to Yang deficiency and Qi deficiency. It must be checked to confirm the diagnosis. Preventive measures for tidal sweating: 1. Drink less alcohol: Alcohol causes the blood vessels in the skin to swell, increasing the body’s heat. 2. Rub some alcohol: Alcohol compresses the pores and can stop sweating for a few hours. This method can only be used occasionally, because excessive rubbing alcohol can cause severe skin dryness and irritation. 3, sprinkle a little talcum powder: Sometimes just spraying some talcum powder can help you absorb excess moisture from your body and make you feel dry. 4, soak in cool water: Soaking in cool water will temporarily inhibit sweating. Soaking the affected area in cool water for 30 minutes will shrink the pores enough not to sweat for 3 hours. 5, treatment of emotional tension drugs: For patients who are often nervous and emotional, you can use internal drugs such as glutathione, bromelain and diazepam to relieve tension and thus reduce the increase in sweating caused by emotional tension. 6, avoid eating hot, spicy food: eat less food that will make the stomach hot, the body will reduce sweating.
