What is a critical step to take if you fall overboard in cold conditions?

Staying calm when you fall overboard in cold conditions is critically important because it helps conserve energy and maintain body heat. When panic sets in, a person may expend valuable energy through erratic movements and may even become hyperventilated, which can lead to increased heat loss and a faster onset of hypothermia. Remaining calm allows you to strategically assess your situation, call for help if possible, and consider strategies to keep your body temperature from dropping too quickly, such as using the Heat Escape Lessening Posture (HELP) or huddling if there are others in the water with you. This composed approach also enhances your chances of survival until rescue arrives.
