State of flow or “living in the zone”
When reaching the optimal state of flow the brain releases five chemicals, i.e. norepinephrine, dopamine, serotonin, anandamide, and endorphins according to The neurochemistry of flow states and that is when we can perform our best.
Now, can you understand why humans can become so addicted to drugs instead of achieving the higher state of consciousness through natural activities without disturbing the body’s natural compass, or mechanisms? Taking external substances messes with the brain and with the release of chemicals.
