What is a sign of severe hypothermia in divers?

Severe hypothermia occurs when a person's core body temperature drops significantly below the normal range, leading to dangerous physiological changes. One key sign of this condition is impaired coordination. In cases of severe hypothermia, the nervous system is affected, leading to decreased motor function and coordination difficulties. This results in situations where a diver may struggle to perform simple tasks or maintain control of their movements, which can be life-threatening underwater.

The presence of impaired coordination is an indication that the body's ability to function effectively has been compromised, making it clear that immediate action is necessary to warm the individual and prevent further health complications. Recognizing this symptom in divers is critical, as it can help in identifying those at risk and can prompt timely intervention.
