Why Do I Keep Getting Chills Even Without a Fever?

Getting chills without a fever can happen for several reasons. Sometimes it is simply your body reacting to cold, stress, or fatigue. In other cases, it may be related to an infection, low blood sugar, anemia, or another health issue.

If the chills keep returning or come with other symptoms, it is worth looking into the cause.

Why Can I Get Chills Without Having a Fever?

Chills happen when your muscles rapidly tighten and relax to produce heat.

A fever is one possible trigger, but not the only one. You may also get chills when your body is cold, under stress, low on energy, or reacting to changes inside the body.

Could an Infection Cause Chills Without a Fever?

Yes. Some infections can cause chills before a fever develops, or without causing a noticeable fever at all.

You may also have symptoms such as:

• Cough or sore throat
• Burning when urinating
• Body aches
• Fatigue
• Stomach upset

The other symptoms you have can help point toward the cause.

Can Low Blood Sugar Cause Chills?

Low blood sugar can make you feel cold, shaky, sweaty, weak, or lightheaded.

This may happen if you skip meals, exercise without eating enough, or take certain diabetes medications.

Eating regularly may help if your symptoms are related to long gaps between meals.

Could Stress or Anxiety Be Causing It?

Stress and anxiety can sometimes trigger shaking or chills.

When your body releases stress hormones, you may notice trembling, a racing heartbeat, sweating, or a sudden cold sensation even when the room is warm.

Can Anemia Make Me Feel Cold or Chilled?

Yes. Anemia can make it harder for your body to deliver enough oxygen to your tissues.

Along with feeling cold, you may notice unusual tiredness, weakness, shortness of breath, dizziness, or pale skin.

A blood test can help determine whether anemia is contributing to your symptoms.

When Should I See a Doctor?

Consider getting checked if the chills:

• Keep coming back
• Last for a long time
• Happen without an obvious reason
• Come with unusual fatigue, dizziness, pain, or weakness
• Are getting more frequent

Recurring chills can have several possible causes, and the best approach is to identify what is triggering them.
