Understanding the Relationship Between Fever and Heart Rate
What is a Fever?
- A fever is a temporary rise in body temperature, often caused by an infection. It’s your body’s natural response to fight off illness.
How Fever Affects Heart Rate:
When you have a fever, your body works harder to regulate temperature. This increases your metabolic rate, which in turn elevates your heart rate.
- Why Heart Rate Increases: The heart pumps faster to ensure enough oxygen and nutrients are delivered to your organs as your body works to cool itself down.
- Normal Increase: For every degree Celsius increase in body temperature, heart rate typically increases by 10-15 beats per minute. This is a normal physiological response.
When Should You Be Concerned About an Increased Heart Rate During Fever?
Normal vs. Concerning Heart Rate:
- While a mild increase in heart rate during a fever is common, there are instances when it may be a cause for concern, particularly for individuals with heart disease or other underlying health conditions.
- Tachycardia and Fever: If your heart rate exceeds 100 beats per minute while at rest, especially during fever, it may be classified as tachycardia, which should be monitored closely.
- Symptoms to Watch For:
- Dizziness or lightheadedness
- Shortness of breath
- Chest pain
- When to Seek Medical Attention: If these symptoms occur alongside a fever and an elevated heart rate, you should consult a healthcare professional immediately.

Hydration is Key:
- Staying hydrated helps regulate your body temperature and can alleviate the stress on your heart. Drink plenty of fluids like water, soups, and electrolyte-rich drinks to support your body’s recovery.
Rest and Relaxation:
- Resting allows your body to focus its energy on fighting off the infection, which can help stabilize your heart rate. Avoid strenuous activities when you’re running a fever.
Medications:
- Over-the-counter medications like paracetamol or ibuprofen can help reduce fever and lower your heart rate. Always consult a doctor, especially if you have pre-existing heart conditions.
Regular Monitoring:
- Use a thermometer to track your temperature and a heart rate monitor or fitness tracker to keep an eye on your pulse. If your heart rate remains high even after your fever subsides, follow up with your healthcare provider.

Fever often causes an increase in heart rate, which is typically a natural and temporary response. However, it’s essential to monitor your heart rate, especially if you have underlying health issues. Stay hydrated, rest, and consider taking medication to manage both fever and heart rate.
