These are distributed over the entire body but are most numerous on the palms and soles. Since the time of the ancient Greeks, the significance of sweating has been recognized, whereas our understanding of the mechanisms and controllers of sweating has largely developed during the past century. Heat dissipation is vital for our survival during exercise and heat stress. In humans, the primary mechanism of heat dissipation, particularly when ambient temperature is higher than skin temperature, is evaporative heat loss secondary to sweat secretion from sweat glands. Normally humans produce as much as one liter of sweat per day; however most of this evaporates as soon as it is produced so we don’t notice it. The body produces […]
