Which of the following is NOT a method to prevent cold injury?

Wearing tight clothing is not a method to prevent cold injury because tight clothing can restrict blood circulation. Proper circulation is essential for maintaining body temperature, especially in cold environments. When clothing is too tight, it can impede the flow of warm blood to extremities, which increases the risk of cold injuries, such as frostbite.

In contrast, wearing loose layers allows for better insulation and the ability to trap warm air, while also providing flexibility for movement. Wearing headgear is critical as a significant amount of body heat can be lost through the head, so keeping it covered helps retain warmth. Changing wet clothes promptly is essential since wet fabric draws heat away from the body, increasing the chances of hypothermia and other cold-related issues.
