When you breath the oxygen goes into your blood stream and is transmitted throughout your body but when you do things you need more oxygen so your heart pumps faster to get you enough oxygen. When you relax you are doing very little so you do not need much oxygen so your heart speed slows down.

When you relax, your body activates the parasympathetic nervous system, which is responsible for rest and relaxation. This system helps to slow down your heart rate by releasing acetylcholine, a neurotransmitter that decreases the firing rate of the heart's pacemaker cells. This results in a lower heart rate as your body shifts into a state of calm and rest.
