True or False: Wet clothing increases heat loss more than dry clothing.

• A. Not sure
• B. Sometimes
• C. True
• D. False

Answer: (C)

Wet clothing reduces insulation and accelerates heat loss because water inside the fabric replaces trapped air, which normally slows heat flow. Water conducts heat far more efficiently than air, so heat moves from the body to the surroundings through the wet fabric much more quickly. In addition, moisture evaporating from the skin and clothes absorbs latent heat, producing further cooling. This combination makes wet clothing a much greater conduit for heat loss than dry clothing, especially in cold or windy conditions. So the statement is true.
