At approximately what temperature does unconsciousness occur due to hypothermia?

• A. 28 degrees Celsius
• B. 30 degrees Celsius
• C. 32 degrees Celsius
• D. 34 degrees Celsius

Answer: (C)

Unconsciousness due to hypothermia typically occurs around 32 degrees Celsius. At this temperature, the body's core temperature has dropped significantly, affecting the normal functioning of the central nervous system. The body becomes unable to maintain necessary biological processes, leading to confusion, disorientation, and eventually unconsciousness.

Hypothermia alters respiratory and cardiovascular functions, contributing to vital reflexes being impaired. As the temperature decreases further, the risks of severe consequences increase, including cardiac arrest. Recognizing this temperature threshold is critical in emergency situations, as immediate medical intervention is required to restore body temperature and prevent fatal outcomes.

While other temperature options are relevant in discussions about hypothermia's progression, 32 degrees Celsius is the most widely recognized benchmark where serious complications, including loss of consciousness, are likely to begin.
