To prevent convective heat loss, air movement around the body must be eliminated or reduced. Convective heat loss occurs when cold air moves across the skin and carries away body heat. By minimizing the movement of air around the body, you can reduce the heat loss that results from this convection process. This is why options such as wearing windproof clothing or seeking shelter from the wind are recommended in cold environments to maintain body temperature.

In situations where air movement is high, even ambient temperatures that seem warm can lead to significant heat loss, making it vital to find ways to limit this airflow. Reducing air movement can be a key factor in maintaining warmth in rescue or survival scenarios, helping to prevent hypothermia and other cold-related injuries.
