Why does my heart rate slow down when i relax?

A doctor has provided 1 answer

Parasympathetic : The hr is influence by sympathetic ( adrenergic) and parasympathetic forces. Adrenergic or sympathetic drive ( fight or flight ) leads to tachycardia and parasympathetic forces leads to bradycardia. When the body relax, there is withdrawal of sympathetic and increase of parasympathetic influence.
