How does humidity influence temperature perception?

Humidity significantly influences temperature perception due to its impact on the body's ability to regulate heat through sweating. When humidity levels are high, the air contains a large amount of moisture, which impairs the evaporation of sweat from the skin. Since sweating is a primary cooling mechanism for the body, high humidity can lead to a feeling of increased heat because the body cannot cool itself as effectively.

In contrast, low humidity allows sweat to evaporate more efficiently, enhancing the body's cooling process and often resulting in a cooler perceived temperature even if the actual temperature remains constant. Therefore, high humidity levels can create a sensation of warmth, making conditions feel hotter than they actually are, which is why the correct answer indicates that humidity can make temperatures feel warmer. The other choices don’t accurately reflect this important interaction between humidity and heat perception.
