Why can an increase in atmospheric humidity make heat feel more intense to humans?
Answer and explanation
Correct answer: Because more water vapour can slow evaporation of sweat
The body cools itself mainly when sweat evaporates from the skin, because evaporation removes latent heat. When relative humidity is high, the air already contains much water vapour, so evaporation becomes slower and less efficient. Body heat is therefore removed less effectively, making conditions feel hotter. Option A explains this; the other options are unrelated to thermoregulation.
