heart beat increases while excersiceing,heart beat increases when we are put to preasure,what 's difference.

Answer 1

When you exercise, you make additional demands on the heart, which causes it to pump more blood, resulting in an elevated heart rate. Jogging, for instance, is called aerobic exercise since it demands more oxygen. Excitement or fear release of chemicals into the blood--adrenaline in the presence of danger--which cause the heart rate to rise. The second, while a necessary response--the adrenaline may dictate an instinctictive response in the sudden presence of a lion, leading to instant flight--does not necessarily strengthen the heart muscle. Repeated episodes of stress may in fact be bad for the cardio-vascular system. Exercise on the other hand strengthens the heart.
