The sweating is not necessarily caused by kidney yin deficiency, although kidney yin deficiency can also cause sweating, but kidney yin deficiency sweating is hot flashes and night sweats, usually sweating after falling asleep, and sweating will stop immediately after waking up. However, there is another type of sweating that occurs due to the lack of consolidation of the Wei Qi and the deficiency of the surface Qi. This type of sweating is usually more intense after activity, sweating like water, and the surface feels cool after sweating. There is also a kind of sweating because the body is too rich in damp heat, damp heat forcing out the fluid appears easy to sweat. However, the sweating caused by damp heat is more sticky, also more yellow, there may also be a pungent smell. So, you can’t simply say that sweating is caused by Yin deficiency, but most of the sweating caused by Qi deficiency will be more common.
