Relative humidity is a measure of the amount of water vapor contained in the air, divided by the maximum amount the air can hold, expressed as a percent. A relative humidity of 50% means the air contains ½ of the water vapor it can actually hold. The maximum amount of water vapor the air can hold is dependent upon the temperature (the "relative" in relative humidity). The higher the temperature, the more water (actually water vapor) the air can hold. For example, air with a temperature of 32°F can hold about 0.16 ounces of water. Air with a temperature of 80°F can hold about an ounce of water. So, what does this all mean? Sweat is evaporated (changes from a liquid to a gas, i.e. water vapor) when heat is added. The heat is supplied by your body. The results are summed up in the table below...
