Question

what is the main cause of high heart beat during strssful situations

Answer 1

Hey there,
Thanks for asking this question.
Well our body has evolved in a way that in stressful situations it gives rise to two modes
They are
•Fight mode
•Flight mode
Now in fight mode Adrenaline is secreted in our body which makes our heartbeat faster providing us with more oxygen and more energy to fight stressful situations.
While in flight mode the same adrenaline makes our heartbeat faster and increases oxygen supply so that we may have enough energy to run from the situations.

When you exercise or do some physical activity at that time too heart beat increases since our body needs more oxygen that time and thus the increase heartbeat increases the oxygen supply to our body parts making us having superhero strength.

Hope it Helps
