Chills are a feeling of coldness and shivering, often along with a fever. They are not a disease themselves but a sign that something is going on in your body, like an infection.
Key facts
Yes, chills are very common. Most people experience them at some point, often when they have a cold, flu, or other infection.
Anyone can get chills, but they are more common in people with weakened immune systems, young children, older adults, and those with chronic health conditions.
To find out what is causing your chills, your doctor or nurse will ask about your symptoms, any recent travel, and your medical history. They will also check your temperature and listen to your heart and lungs.
The doctor will try to find the underlying cause. They will explain what they think is happening and any treatments you might need. Most tests are quick and not painful. You may need to wait a day or two for results.
Treatment for chills depends on what is causing them. Often, treating the underlying infection or illness will make the chills go away. You can also do things at home to feel better.
If chills are from an infection, your doctor may recommend antibiotics or antiviral medicines. For other causes, they will treat the specific condition. Do not take any medicine without checking with your doctor, especially for children or if you have other health problems.
Chills usually do not last long. While you have them, focus on rest and drinking fluids. Keep an eye on your temperature and other symptoms. Most people recover quickly.
Eat healthy foods like fruits, vegetables, and whole grains to support your immune system. Gentle movement is fine if you feel up to it, but rest is more important when you have chills.
Feeling sick and chilly can make you feel anxious or down. It is normal to be worried. Try deep breathing or talking to someone you trust. If the worry does not go away, talk to your doctor.
You cannot always prevent chills, but you can lower your risk of getting infections that cause them. Good hygiene and staying healthy help.
Vaccines against flu, pneumonia, and other illnesses can prevent some infections that cause chills. Ask your doctor which vaccines are right for you.
Routine health checks can catch problems early. There is no specific screening for chills, but maintaining regular check‑ups helps your overall health.
For most people, chills are a temporary sign that the body is fighting something. With rest and proper care, you usually recover fully. Even when chills are from a serious infection, early treatment leads to good outcomes.

Surgery is not usually needed for chills themselves. Only if an infection requires draining an abscess or removing an infected organ – but this is very rare.
