Is sweating on your hands and feet in winter yin deficiency or yang deficiency

Winter sweating on hands and feet may be due to yin deficiency or yang deficiency.

When yin deficiency occurs, due to insufficient yin fluid in the body, the function of restricting yang heat is weakened, so there will be deficiency heat syndrome with relatively high yang qi, manifested as sweating on hands and feet in winter. If yang deficiency occurs in patients, it can lead to unconsolidated striae, which in turn causes sweat leakage, causing sweating on hands and feet in winter. However, other factors can also cause sweating on hands and feet in winter, such as wearing too much clothes, hyperhidrosis, tuberculosis, etc. Therefore, we can not judge yin deficiency and yang deficiency simply according to sweating of hands and feet in winter. We can go to the hospital for observation, smell, inquiry, palpation, etc. to make a clear diagnosis.
