What is Hypothermia?

Hypothermia is defined as a medical condition that occurs when the core body temperature drops below 35 degrees Celsius (95 degrees Fahrenheit). This drop in temperature impairs the body's ability to function properly and can lead to serious health risks, including confusion, loss of motor skills, and ultimately, life-threatening situations if not treated promptly.

The body normally maintains a temperature around 37 degrees Celsius (98.6 degrees Fahrenheit), and deviations from this can result in various physiological reactions. When the temperature falls to critical levels, the body's thermoregulation fails. This condition is particularly concerning in cold environments or during immersion in cold water, which is particularly relevant for lifeguards who need to be aware of the risks associated with hypothermia.

Understanding hypothermia is essential in lifeguarding as it impacts the assessment and treatment of individuals who may have been exposed to cold water or environments. Recognizing the signs and symptoms early enables lifeguards to respond effectively and prevent further complications.
