Feeling cold and vomiting together often indicates an infection, such as the flu or norovirus. These symptoms arise from your body's immune response to pathogens.
When viruses or bacteria invade your system, your immune system triggers inflammation. This can cause fever (making you feel cold) and irritate the stomach lining, leading to vomiting. The vagus nerve, which connects the brain to the gut, plays a key role in this response.
The most common causes of feeling cold and vomiting are:
According to the Centers for Disease Control and Prevention (CDC), norovirus alone causes 58-70,000 hospitalizations yearly in the U.S.

Contact a healthcare provider if you experience:
The Mayo Clinic recommends seeking immediate care if vomiting blood or black material occurs.

To reduce risk:
The CDC emphasizes that handwashing can prevent about 30% of diarrhea-related illnesses.
