What happens if the parasympathetic nervous system is damaged?

It can affect blood pressure, temperature control, digestion, bladder function and even sexual function. The nerve damage interferes with the messages sent between the brain and other organs and areas of the autonomic nervous system, such as the heart, blood vessels and sweat glands.

How does stress affect the parasympathetic nervous system?

When you are stressed, this system triggers these necessary responses, and the function of your rest and digest system is reduced. The parasympathetic system is responsible for suppressing heart rate and bringing you back down to homeostasis. Another hormone released when we are stressed is cortisol.
