Transepidermal Water Loss - an overview ScienceDirect Topics

WebWater moves through the skin in liquid (active sweating) and gaseous states (transepidermal water loss).However, when air temperatures exceed those of the skin, the only physiological avenue for heat loss is through the recruitment of eccrine sweating, and the unisexual reference adult 15 has about 2.03 million functional glands (95% confidence … WebThe middle layer of the skin, or dermis, stores most of the body's water. When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
