Rigors vs. Chills: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 29, 2024
"Rigors" are intense shivering associated with a high fever, usually indicating a serious medical condition, while "chills" are milder shivers that may not be linked to fever.

Key Differences

Rigors are severe, often involving teeth chattering and body shaking, typically indicating a serious medical condition like an infection. Chills, however, are generally milder, often experienced as a light shivering sensation without the intensity of rigors.

Rigors are commonly associated with a sudden increase in body temperature and are often a symptom of high fever. Chills can occur with or without fever, often as a result of feeling cold or as a mild symptom of various health conditions.

Rigors are usually more intense and can last longer than chills. They are often so severe that they cannot be controlled. Chills, on the other hand, are typically less intense and can often be alleviated with warm clothing or blankets.
