What can help prevent hypothermia in cold water rescues?

Using a wet suit is essential in preventing hypothermia during cold water rescues because it provides thermal insulation to the body. Wet suits are designed to trap a thin layer of water between the suit and the wearer's skin. This water is warmed by body heat, helping to maintain a stable core temperature in cold water conditions. They also reduce the heat loss from the body, which can occur rapidly in cold environments, thus significantly lowering the risk of hypothermia.

In addition to their insulating properties, wet suits also offer coverage that protects against wind and water exposure, further enhancing thermal protection. This makes them a critical piece of equipment for rescuers and victims alike when navigating cold water situations.
