The human core body temperature is normally 37°c no matter what the temperature of the surroundings or the
activity level of an individual. to reduce the body temperature, sweating occurs. sweat is mostly water with some
salt. it is produced by the sweat glands and pours out onto the surface of the skin. how does sweating to cool
and regulate body temperature?
the increased salt concentration of the body's cells maintain a lower
body temperature.
water has a high heat of vaporization; the human body can dissipate
excess heat by the evaporation of sweat.
the low specific heat of water allows it to readily evaporate into the
atmosphere, quickly cooling your body.
water's cohesive properties cause water molecules to stick together
requiring the body's thermal energy to evaporate sweat into the air.
