What is defined as hypothermia?

Hypothermia is defined as a condition that occurs when the body temperature drops below the normal range necessary for proper bodily functions. Normal human body temperature typically hovers around 98.6°F (37°C). When a person's body temperature falls significantly below this level, it can impair the body's ability to regulate other vital functions and can become life-threatening. This makes the definition provided in your answer the correct choice. Understanding hypothermia is especially crucial for motorcyclists, as exposure to cold weather can lead to this condition more quickly while riding, even during seemingly mild weather if a rider is not adequately protected.
