How to break a fever: 6 tips to manage your symptoms and get relief

Fever is the body’s natural response to infection, but it can leave you feeling drained and uncomfortable. However, knowing how to break a fever can provide relief while supporting your recovery. 

If you or a loved one is experiencing a fever, here are practical ways to lower a fever, how long it typically takes for it to subside, and guidance on when to seek medical care for a fever.

What temperature is considered a fever?

A fever is generally defined as a body temperature above 100.4°F (38°C) and often indicates that your immune system is fighting off an infection of some kind.

While it’s a common symptom of illnesses like colds, the flu or other viral and bacterial infections, it’s essential to monitor your temperature to determine if further action is needed.

6 ways to break a fever

"Breaking” a fever is a term for supporting your body as it fights off illness. While fever-reducing medications can help, there are other natural remedies that may provide additional relief. 

1. Drink plenty of fluids

Staying hydrated is crucial when you have a fever. A fever increases your body’s temperature, which can lead to fluid loss through sweating. Staying hydrated by drinking water, herbal teas or electrolyte-rich drinks helps prevent dehydration and keeps your body functioning. It is recommended that you avoid consuming sugary beverages or alcohol when running a fever, as they can intensify dehydration.

2. Eat when you feel like it

When you’re sick and running a fever, your body’s energy is focused on fighting the infection, so your appetite may decrease. Try to eat small, nutrient-rich meals when you’re hungry to provide your body with the fuel it needs to heal itself. Foods like soups, broths and fruits can be soothing and easy to digest. Don’t force yourself to eat if you’re not hungry—focus on hydration instead.

3. Stay cool

Help lower your body temperature by creating a cool environment. Wear lightweight clothing and keep your room at a comfortable temperature. While you may feel cold or have chills when running a fever, it’s best to avoid over-bundling yourself in heavy blankets, as this can trap heat and worsen your fever. Cooling measures like placing a damp cloth on your forehead may also provide temporary relief.

4. Get plenty of rest

Rest is essential for recovery. Sleep allows your immune system to fight off infection more effectively. When running a fever, avoid strenuous activities and give your body the time it needs to heal. Short naps and extended nighttime sleep can make a difference in how quickly you recover.

5. Take over-the-counter medication

Medications like acetaminophen and ibuprofen can reduce fever and alleviate discomfort. These medications work by lowering your body’s temperature and addressing symptoms like headaches or muscle aches. 

6. Take a lukewarm bath

A lukewarm bath can help regulate your body temperature by gently cooling your skin. Soaking for 10 to 15 minutes may provide temporary relief and help you feel more comfortable.

How long does it take for a fever to break?

Most fevers last one to three days, depending on the underlying cause. If your fever is due to a viral infection, it typically resolves on its own as your body fights off the illness. Bacterial infections may require antibiotics for full recovery. Persistent fevers lasting more than three days or recurring fevers should be evaluated by a healthcare professional.

When should you go to the doctor for a fever?

Knowing when to talk to a doctor regarding a fever is important. In general, you should consult with your primary care provider if your fever lasts several days, is accompanied by severe symptoms or persists despite home remedies. Prompt care can ensure proper treatment. 

Infants

A fever in infants may require extra attention. Contact your child’s pediatrician if:

• Your baby is under three months old with a temperature of 100.4°F (38°C) or higher.
• Your baby is three to six months old with a temperature over 102°F (38.9°C) or has a lower fever but appears unusually irritable, sluggish or uncomfortable.
• Your child is seven to 24 months old with a temperature over 102°F (38.9°C) lasting more than a day without other symptoms. It is recommended that you call sooner if they show additional signs like a runny nose, cough or diarrhea

Children

Fevers in children aren’t always a cause for concern if they’re alert, making eye contact and staying hydrated. However, you should contact a doctor if your child:

• Appears listless, confused or avoids eye contact
• Is unusually irritable, vomits repeatedly or has severe discomfort from symptoms like a headache, sore throat or stomachache
• Has a fever lasting longer than three days
• Experiences a seizure

If your child has a preexisting condition or weakened immune system, consult with your pediatrician for more detailed advice.

Adults

In adults, a fever of 103°F (39.4°C) or higher may signal a need to call your healthcare provider. Always listen to your body and seek care if you’re unsure about the severity of accompanying symptoms to a fever, which may include:

• Severe headache or rash
• Sensitivity to bright light
• A stiff neck or neck pain with movement
• Mental confusion or slurred speech
• Painful urination
• Convulsions or seizures

When should you go to the hospital for a fever?

Not all fevers require an immediate trip to the emergency room. The need for care can depend on both the temperature and accompanying symptoms. Here’s what to watch for across varying age groups and when a trip to the hospital emergency room may be necessary:

Infants (0–3 months): Head to the ER if your infant is 30-60 days old and has a temperature of 100.4°F (38°C) or higher along with any additional symptoms such as a rash, difficulty breathing, refusal to eat or persistent crying.

Children: In children, a fever over 102°F (38.9°C) lasting two days or more may indicate the need for emergency care, especially if paired with difficulty waking up or loss of consciousness, breathing or swallowing difficulties, persistent vomiting, inability to urinate or abdominal pain. 

Adults: For adults, a fever of 105°F (40.5°C) or higher is a sign that it’s time to visit the emergency room. Seek immediate care if the fever is accompanied by shortness of breath or difficulty swallowing, chest pain, abdominal pain or trouble urinating.

When it comes to fevers, always err on the side of caution. If your fever persists or you (or your child) are experiencing concerning symptoms, contact your provider or find an Urgent Care+ location near you. By understanding how to manage and monitor a fever, you can take the necessary steps to feel better sooner.
