11. Chills (Feeling Cold)
Chills are shivering or unusually cold episodes that may accompany fever during food poisoning. Chills can occur as the body’s temperature regulation mechanisms respond to fever and temperature fluctuations. The body may perceive an increase in core temperature during fever as a drop in external temperature, leading to shivering and a sensation of coldness. Chills are a common and temporary symptom associated with fever and are part of the body’s effort to raise its temperature to fight off infection.
