Question

When do you think our pulse rate goes up?​

Answer 1

Answer:

Mental or physical stress increases the activity of the autonomic nervous system. When under stress, the central nervous system orders the heart, as well as your brain and large muscles, to prepare for a fight-or-flight situation. This leads to an increase in your resting heart rate.

heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.

Many factors influence your resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow it down. (In his prime, champion cyclist Miguel Indurain had a resting heart rate of just 28 beats per minute.) Stress, medications, and medical conditions also influence your resting heart rate.
