Quizplus · Accepted Answer

The heat index (HI) is a measure used by the National Weather Service that combines air temperature and relative humidity to determine the human-perceived equivalent temperature, or "feels like" temperature. This is because high humidity levels can make the actual air temperature feel hotter than it is by hindering the evaporation of sweat from the skin, which is a key cooling process for the body.
