What is the final stage of cold water immersion?

The final stage of cold water immersion is characterized by unconsciousness due to a dropping core temperature. As a person is exposed to cold water for an extended period, their body gradually loses heat, leading to hypothermia. In the advanced stages of hypothermia, the body's core temperature drops significantly, affecting the brain and leading to confusion, exhaustion, and eventually unconsciousness.

This underscores the critical nature of hypothermia in cold water situations, as it can impair cognitive function and physical ability, making rescue and recovery increasingly difficult. Recognizing these stages helps individuals understand the importance of prompt action and safety measures when dealing with cold water environments.
