Fever changes the body temperature. This change can destroy some causes of illness. As the brain “turns on” the ‘we need to be warmer” switch, you feel cold because you are below your target temperature. It’s the physiological response because you’ll get warmer if you do more to retain heat.

Chills without a fever are the same cause, just out of order. You may never actually develop a fever. But your body thinks you need to be warmer because you aren’t warm yet.
