Does fever cause fast heart rate?

While a higher heart rate is common during a fever, you must be very careful. If you feel chest pain, extreme breathlessness, or if your heart keeps racing even after taking paracetamol and bringing the temperature down, please go to the hospital immediately. It is always better to be safe and let a doctor check your heart.

I totally get it, that racing heart feeling when you are already sick is so scary and uncomfortable. It makes you feel very restless in bed. Just try to take deep, slow breaths and keep a damp cloth on your forehead. You are not alone, this happens to most of us during a fever.

Yes, a fast heart rate is a very normal response to fever. Try to keep yourself cool, take your prescribed medicine, and rest as much as possible. It will get better soon.

This happened with my daughter during her viral fever last month; her chest was beating so fast I got terrified. Our pediatrician explained that for every degree rise in temperature, the heart rate increases quite a bit. Just keep giving them fluids and monitor the temperature closely.
