We all know that sunny days, sweet treats, warm bread, and the scent of vanilla make most of us feel better when we’ve got a case of the blues, but the reason why is not common knowledge. The answer lies deep in our nervous systems and the intricate communication between nerve cells. Neurotransmitters, chemical messengers that catalyze a myriad of metabolic functions, also affect our moods and behaviors. Some calm the body, promote digestion, and support good immunity while others are involved in keeping memory sharp, triggering the fight or flight stress response, and filling us with feelings of euphoria when we are in love or engaging in daredevil behavior. There are many neurotransmitters, but the body’s heavy hitters are serotonin, dopamine, acetylcholine, norepinephrine, and GABA. All of these are essential to life and well-being and work with each other toward the body’s homeostasis or state of equilibrium.
Poor diet, unrelenting stress, too much coffee or sugar, not enough physical activity, inadequate rest, and predisposed genetic deficiency all contribute to neurotransmitter dysfunction, especially that of serotonin. Inadequate or too much serotonin—as well as impairment of how the body utilizes it—has numerous consequences that can be the underlying factor in depression, anxiety disorders, obesity, Seasonal Affective Disorder (S.A.D.), premenstrual syndrome (PMS), Irritable Bowel Syndrome (IBS), osteoporosis, chronic insomnia, low energy, compromised immunity, even diseases of the cardiovascular system.
