What is the Sympathetic Nervous System and what does it do?
Answered by verified global health professionalsDr. Himabindu SreenivasuluMBBS · 1 years of exp
The Sympathetic Nervous System is like your body's fight or flight system. When you're faced with danger or stress, it revs up to help you react quickly. It increases your heart rate, makes you breathe faster, and sends more blood to your muscles so you can run or fight. It also releases stress hormones like adrenaline. It gets your body ready to handle intense situations and keep you safe.
- The sympathetic nervous system is a part of the nervous system that is involved in preparing the body for stress-related activities12. It is responsible for the body's stress response and is activated when you perceive danger2. The brain sends messages to the rest of the body to prepare for and respond to danger, initiating a fight, flight, freeze, or fawn stress response2. These processes are not under direct conscious control, occurring automatically without conscious thought1.
