Chills are how people's bodies respond when they get cold. It's the body's way of producing heat. Specifically, the chills come from an individual's muscles contracting and relaxing rapidly to generate that heat.

Often, a person gets chills accompanied by a fever when they have a virus like the flu. However, if a person experiences chills and no fever, they may wonder why. There are several causes of chills with no fever. Plus, there are ways to remedy this unpleasant symptom when it develops, and it helps to know when to see a doctor.

1. Low Blood Sugar

People's blood sugar fluctuates throughout the day as they consume food and burn energy. A person usually doesn't notice this constant increase and decrease in blood sugar levels as long as it stays within the normal range.

However, a decrease that causes sugar levels to drop below the normal range could cause symptoms such as nausea or jitteriness. A person might feel anxious or irritable, and they could also experience the chills and a headache. In addition, it's possible that the individual may feel excessively hungry, tired or weak.1‘Hypoglycemia (Low Blood Glucose).
