There are many reasons for sweaty hands. First, hand sweating. Hand sweating is caused by tension, excitement, stress or sympathetic nerve hyperactivity in the summer heat, resulting in an abnormal increase in sweating on the palms of the hands, so controlling tension and suppressing excitability can inhibit sweating on the hands. Second, sweaty palms. In the case of inactivity or light activity during the day, often sweating will not stop. These people are usually weaker, speak in a lower voice, have a poorer appetite, and are prone to colds. They should increase their body resistance and relieve qi deficiency; third, they are what Chinese medicine calls night sweats. These people often have sweaty hands and feet, a hot heart, a red, hot face, and a dry mouth and throat, which are considered in Chinese medicine to be signs of yin deficiency. These people can choose lily, snow pear and other nourishing Yin products, and eat less hot foods such as mutton, onion, ginger and garlic. Paying attention to the above details can help reduce the occurrence of sweaty hands.
