Heat Index Temperature vs. Humidity How to read the chart: find the temperature on the left hand side, then move to the right until you find the column for the approximate relative humidity. With this gurgling volcano of active internal organs, the body has a critical need to dissipate heat to the surroundings. It does so by circulating blood near the surface of the skin, by exhaling warm, humidified air, and by evaporating sweat.

These processes function best when ambient temperature is around 70 degrees Fahrenheit, where we feel most comfortable, and they serve to maintain core body temperature around 98 degrees F. But when the surroundings match core body temperature, the dispersal mechanisms are not optimal, so we feel hot, especially when humidity is high. Humidity has a significant effect because water on the body absorbs enormous amounts of heat and then dissipates it by evaporation.

Anything that interferes with this vaporization of water humid air, lack of a breeze, heavy clothing, and so on makes us feel especially hot and uncomfortable. Already a subscriber? Sign in.
