Additionally, intense physical exertion can trick the system; the muscles generate significant heat during activity, followed by a rapid loss of warmth once the effort stops, resulting in post-exercise chills. Common Non-Infectious Triggers There are numerous reasons why the body might initiate this warming process without an actual infection elevating the fever.
Understanding Chills With Normal Body Temperature
Tracking when these episodes occur—such as after a meal, during specific times of day, or in relation to stress—can provide valuable clues to the root cause.

Thyroid disorders, particularly hypothyroidism, slow down metabolism and reduce the body's natural heat production, often leaving individuals feeling cold regardless of the ambient temperature. Exposure to cold environments can lower skin temperature significantly, even if the core remains warm, creating a stark sensation of chill.
Understanding Chills With Normal Body Temperature
Even if the external thermometer does not register a fever, the internal biological machinery may be actively working to create one, leading to the feeling of intense coldness and shivering that precedes a potential rise in temperature. Anemia, characterized by a lack of healthy red blood cells, reduces oxygen delivery to tissues, which can manifest as persistent coldness and fatigue.
