When the parasympathetic nervous system is activated, it produces a calm and relaxed feeling in the mind and body. People can learn to trigger their parasympathetic nervous system to immediately reduce their sense of anxiety and stress.
Everything you perceive through your senses – everything you can see, hear, taste, smell, intuit, and touch is processed through the nervous system.
If you’re experiencing chronic stress or feeling constantly on edge chances are you’ve got an overactive sympathetic nervous system. This is the branch of your nervous system that dictates the fight or flight response.
