Which of the following is NOT listed as a factor that contributes to hypothermia?

• A. Temperature
• B. Wind chill
• C. Dampness
• D. Humidity

Answer: (D)

Heat loss is the key factor behind hypothermia, and the environment affects that loss in a few clear ways: how cold the air is, how quickly wind can strip heat away (wind chill), and whether clothing or skin is damp, which conducts heat away and accelerates cooling. Humidity in the air isn’t listed as a direct contributor to hypothermia because simply the amount of water vapor in the air doesn’t, by itself, increase the body's heat loss in the same straightforward way. What matters more is moisture at the skin or on clothing; dampness drives heat loss through conduction and evaporation, raising the risk of hypothermia. Humidity can influence comfort and condensation, but it isn’t treated as a separate factor alongside temperature, wind chill, and dampness.
