What is the term for a core temperature that falls below the normal range?

The term for a core temperature that falls below the normal range is hypothermia. Hypothermia occurs when the body loses heat faster than it can produce it, resulting in a drop in core temperature below the normal range of approximately 98.6°F (37°C). This condition can be life-threatening if not addressed, as it affects bodily functions and can lead to severe complications.

In contrast, hyperthermia refers to an elevated body temperature, typically due to excessive heat exposure or strenuous activity, while hypothyroidism is a condition related to insufficient production of thyroid hormone, affecting metabolic processes but not specifically temperature regulation. Hypoglycemia refers to low blood sugar levels and is unrelated to core body temperature. Understanding these terms helps in recognizing and responding to various health conditions appropriately.
