What happens when the parasympathetic nervous system becomes active during the stress cycle?

When the parasympathetic nervous system becomes active during the stress cycle, the body initiates a process known as the "rest and digest" response. This response is crucial for returning the body to a state of homeostasis following stress. The activation of the parasympathetic system leads to a decrease in heart rate, lower blood pressure, and enhanced digestion, helping the body to recover and restore normal function after experiencing stress or a threatening situation.

This transition is vital because the parasympathetic nervous system counteracts the effects of the sympathetic nervous system, which is responsible for the "fight or flight" response during stressful situations. By calming the body and promoting relaxation, the parasympathetic system facilitates recovery and promotes well-being in the aftermath of stress.
