heat index

Perceived warmth measure

Heat index is a measure of how hot it actually feels when humidity is factored into the air temperature.

High humidity prevents sweat from evaporating efficiently, making the body retain heat.

Weather reports use heat index to warn of dangerous conditions: The temperature was 95°F, but the heat index made it feel like 110.
