Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C).

What does a low temperature indicate?

Why is my body temperature low? Studies show that core body temperature decreases with age. Hypothyroidism, or an underactive thyroid, can also slow down metabolism, which can lead to a drop in body temperature. If your core body temperature dips down to 95 F (35 C) or lower, that's considered hypothermia.

What infection causes a low body temperature?

Diagnosis of Sepsis and Septic Shock

Doctors usually suspect sepsis when a person who has an infection suddenly develops a very high or low temperature, a rapid heart rate or breathing rate, or low blood pressure.
