Rapid heartbeat is a physical response to stress.

Answer 1

Yes, rapid heartbeat is a common physical response to stress. When we experience stress, the body releases stress hormones such as adrenaline and cortisol, which prepare the body for a fight-or-flight response. This leads to an increase in heart rate and blood pressure, allowing the body to pump more oxygen and energy to the muscles. Rapid heartbeat can also be accompanied by other physical symptoms of stress, such as shallow breathing, sweating, and increased muscle tension.
