Evaporative Heat Loss

Energy is required to convert liquid water to a vapor. This energy is referred to as the latent heat of vaporization and is equal to 580 kcal/L of water vaporized. Thus, the rate of heat loss from the body by evaporation (Jq, evap) in kilocalories per hour is directly proportional to the rate at which water evaporates from the skin surface and the respiratory passages (JH o) in liters per hour:

Water is constantly being lost from the body by evaporation, even when the ambient temperature is low. Even under sedentary conditions, the basal rate of insensible (loss from the skin plus the expiration of water-saturated air) water loss is about 500 mL/day, resulting in a loss of approximately 300 kcal/day. The loss of water from the skin surface can be dramatically increased by sweating in a hot environment or with exercise. However, this sweat must evaporate for a heat loss to occur, and the water lost in sweat that drips off the skin results in no heat loss from the body. For this reason, the rate of heat loss by evaporation is very much dependent on the relative humidity of the air. When the air surrounding the skin is saturated with water, no evaporation occurs, and no heat can be lost by evaporation. For this reason, heat loss is much less efficient in a hot, humid climate than it is in a hot, dry climate. This effect is expressed by the heat index given in summer weather reports.
