What should divers do to minimize their risk of hypothermia?

Wearing layers of clothing under the wetsuit is an effective strategy for minimizing the risk of hypothermia while diving. The key reason behind this is that layering enhances insulation and helps regulate body temperature by trapping a thin layer of water warmed by the body, which becomes an insulating barrier against the colder water outside the suit. This method creates additional thermal protection, thereby extending a diver's comfort level in cooler aquatic environments.

In contrast, increasing the length of dives could expose a diver to cold water for longer periods, raising the potential for hypothermia. Choosing warmer dive locations may not always be practical or possible, as divers may need or want to explore other sites regardless of temperature. Reducing air consumption doesn't directly impact a diver's warmth or safety concerning hypothermia, as it relates more to managing air supply than temperature control. The focus on layering promotes better thermal protection, making it the optimal choice to combat hypothermia risks while diving.
