Obviously, prevention is the best option. A person in cold water can do the following to delay the onset of symptoms:
- wear a lifejacket to save energy losses
- individually go into the Heat Escape Lessening Position (HELP) that is similar to a foetal tuck position. By having the arms and legs tucked in close to the body, the body surface area is reduced and thus heat losses will decrease. Students in swimming lessons conducted in cold water will often assume this position whilst stationary
- as a group go into a Huddle. This is when a group of people gather as close as possible to share heat. A sideline benefit is the psychological benefit of group support
- keep the head out of the water and dry if possible or wear a beanie or cap to reduce heat loses. In a swimming lesson situation, wearing bathing caps will provide some benefit
