A member asked:

Why does your heart rate increase when you have a cold or the flu?

A doctor has provided 1 answer

Many reasons: Heart rate increases with fever. It increases with pain (which usually accompanies flu). It increases with dehydration, which happens more quickly than normal if you have a fever and aren't drinking well enough. It increases with combinations of all of the above. Rarely, it happens because the virus that is making you sick effects your heart directly.
