What core temperature defines hypothermia in this material?

• A. 95 F
• B. 98.6 F
• C. 104 F
• D. 88 F

Answer: (A)

Hypothermia happens when the body's core temperature drops below what's considered normal. Normal core temperature is about 98.6°F, with some natural variation. In this material, hypothermia is defined at a core temperature of about 95°F. This threshold marks the point where heat loss begins to outpace heat production enough to slow bodily processes and raise the risk of complications, making 95°F the cutoff used here. The other values correspond to a normal temperature (around 98.6°F), a fever (104°F), or a much lower temperature that still indicates hypothermia but is beyond the defined threshold.
