Hypothermia
Wet plus wind plus pride
Short answer
Cold kills slower than a bullet and faster than your patience.
Also: freezing · too cold
How it works
Hypothermia is a heat-comfort dump. Wet clothes are a multiplier. Sakhal is the exam.
What to do
Dry, insulate, fire if you must, then move. See heat-comfort.
Don't
Don't sit in the rain 'for a second' in a t-shirt.
