The effect nervous system has on the heart rate is
Stimulation by parasympathetic nerves causes the heart rate to slow down.
The two branches of the autonomic (involuntary) nervous system regulate heart rate. The parasympathetic nervous system and the sympathetic nervous system (SNS and PNS) (PNS). To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The hormone acetylcholine is released by the parasympathetic nervous system (PNS) to reduce the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, whereas it may temporarily decrease due to meditation or deep, steady breathing. Any amount of exercise will raise your heart rate, which will stay up as long as you keep exercising.
