Whiteout Survival Science

Whiteout conditions are uniquely dangerous because people lose all orientation. Without visual references, they walk in loops instead of straight lines, so wandering for help often circles you back to where you started.

Hypothermia then progresses in stages. First comes shivering. As core temperature falls, shivering stops and confusion sets in. Strangely, severely hypothermic people sometimes feel burning hot and start removing clothing.

That is why the survival rule of three puts shelter first: you can last roughly three hours without shelter, three days without water, and three weeks without food. In a blizzard, finding shelter beats signaling for rescue every time.
