The heat index shows what the temperature feels like on your body.

According to the National Weather Service, the heat index — also known as the apparent temperature — is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This has important considerations for the human body’s comfort. When the body gets too hot, it begins to perspire or sweat to cool itself off.  If the perspiration is not able to evaporate, the body cannot regulate its temperature. Evaporation is a cooling process. When perspiration is evaporated from the body, it effectively reduces the body’s temperature.
