A lost hiker found disoriented and shivering most likely lost body heat through convection. Convection refers to the process of heat transfer that occurs when a fluid (which can be a liquid or gas) moves past a solid object, in this case, the hiker. When a hiker is exposed to wind or cold air, the air movement carries warmer air away from their body, leading to increased heat loss.

In a wilderness scenario, if the hiker is wet from sweat or rain, the chill effect is intensified as the cooler air accelerates heat loss from the body. This is particularly critical in survival situations, as maintaining body temperature is essential to prevent hypothermia.

Understanding convection is vital for wilderness first responders since it emphasizes the need for insulation and wind protection for individuals in cold environments.
