Sympathetic tone means fight or flight, or your stress response. We now know that an increased sympathetic tone in the nervous system sets off a cascade of autonomic processes as if the body was being attacked.
This increased tone leads to what we know to be the “fight or flight” behavior physiology.
Here is the thing…it is a good response that helps you in the acute situation, but will kill you chronically. What I mean by that is in the short term situation it is good; however, if it stays there long term it will destroy the body.
This increase in sympathetic tone increases stress hormones known as catecholamines (adrenaline and noradrenaline) and decreases relaxing hormones such as serotonin and relaxin.
We are talking about decreased:
Immunity, digestion, fertility, focus, attention, energy
This means under chronic stress, the above will be decreased.
This state of physiology is not what any healthy human should experience for any sustained period of time.

Chiropractic has been proven to decrease the sympathetic tone. By doing this, Chiropractic has to increase Immunity, Digestion, Fertility, Focus, Attention, and Energy.
