At night, I don't have a fever, but I am shivering with cold. Why?

I suddenly feel cold and shivering when I sleep, but my temperature is normal. First of all, you should consider chills caused by fever or chills caused by cold weather. Severe bacteremia can also cause this symptom.

Suggestion:

It is recommended that you keep warm and make further examination and diagnosis if necessary. If it is caused by cold weather, it will generally get better after treatment such as keeping warm and drinking hot water. If it is caused by fever, it will generally get better after anti-infection, anti-virus, anti-inflammatory and antipyretic treatment.
