What does the term hypothermia refer to?

Hypothermia refers to a condition where the body’s core temperature drops to a level that is dangerously low, typically below 35 degrees Celsius (95 degrees Fahrenheit). This drop in temperature can severely impair the body's physiological functions and, if not treated promptly, can lead to serious health complications, including cardiac arrest and even death.

In the context of lifeguarding and emergency response, understanding hypothermia is critical for providing appropriate care to individuals exposed to cold water or extreme weather conditions. The symptoms of hypothermia include shivering, confusion, fatigue, and a decreased ability to think clearly. Therefore, recognizing and responding to this condition quickly is essential in a lifeguard's role to prevent further harm and provide effective first aid.

The other options reflect conditions that do not align with the definition of hypothermia. For example, a dangerous increase in body temperature refers to hyperthermia, not hypothermia. Similarly, a mild cold sensation does not indicate a drop in body temperature severe enough to be classified as hypothermia, and a condition caused by overheating is unrelated as it pertains to elevated body temperature rather than a decrease.
