Canadian Boating Practice Exam – Prep, Practice Test, Questions & Study Guide

The H.E.L.P. position, also known as Heat Escape Lessening Posture, can help someone survive longer when immersed in cold water alone. This position keeps the body as close to the fetal position as possible with the arms tightly against the sides, and the legs crossed and bent at the knees. It is important to stay still in this position to conserve body heat and prevent hypothermia.

The other options are incorrect because standing in cold water can cause loss of body heat, floating face down can lead to drowning, and treading water expends too much energy which can also lead to hypothermia. The H.E.L.P. position is the most effective option for survival in cold water.
