Janesville Chiropractor Explains How the Nervous System Controls Your Health

Nervous System Quote | Janesville, WI ChiropractorJanesville Chiropractor Explains How The Nervous System Controls Your Health

The Medical Physiology textbook by Guyton and Hall states “the term homeostasis is used in physiology to mean maintenance of constant conditions in the internal environment”. In simple terms homeostasis is internal balance within your body. When the body is balanced internally, the body is healthy and properly functioning. Health can be that simple in our daily lives. However, achieving that balance in today’s age with the lack of nutrition in our diets, sedentary lifestyles and increased stress it takes focus and discipline to maintain your health.

The major system controlling homeostasis is the autonomic nervous system (ANS). The ANS is a division of the Central Nervous System and is comprised of 2 parts the sympathetics and the parasympathetics. The sympathetics control the fight or flight response and act as your defense mechanism. When the sympathetics are stimulated, your heart rate and blood pressure increases, your thyroid and adrenal gland secretion increases, your bronchi in the lungs dilate, your digestion decreases and much more. The parasympathetics allow nourishing, healing, and regeneration to occur in your body. When the parasympathetics are stimulated your heart rate and blood pressure lowers, your thyroid and adrenal gland secretion increases, your bronchi in the lungs contract, your digestion increases and much more. When you eat lots of sugars, drink lots of caffeine or energy drinks, and get stressed out you are constantly stimulating your sympathetics which causes the parasympathetics to shut down. If one stays in a state of sympathetic stimulation long enough, the sympathetics will shut down causing a feeling of burn out and exhaustion in your daily life. The key to health is balance (Homeostasis) between the sympathetic and parasympathetic nervous systems.

Many common conditions we see today such as high blood pressure, anxiety, irritability, insomnia, erectile dysfunction and attention deficit disorder are all effects of a body that is in a state of sympathetic dominance. Conditions such as depression and chronic fatigue are an effect of a body that is in a state of parasympathetic dominance which occurs primarily after the sympathetics have been exhausted from overuse.

Once the imbalance in your Autonomic Nervous System occurs, how do you balance the sympathetics and parasympathetics?

Exercise, Healthy diet, and Meditation is a great start to establishing your internal balance.  The single most effective method for balancing the sympathetics and parasympathetics is chiropractic care. A chiropractic adjustment can instantly calm the sympathetics and stimulate the parasympathetic response. The sympathetics are located in your Thoracic and Lumbar spine. The parasympathetics are located in your Upper cervical and Sacral region. An adjustment to the Atlas(C1) vertebra has been proven to lower blood pressure which is a parasympathetic response. This is possible because you stimulate the parasympathetics when you adjust this region and the parasympathetics will lower heart rate and that will lower blood pressure. When the sympathetic and parasympathetic systems are working in balanced harmony (homeostasis) you can deal with the ups and downs of daily life with ease. When challenged by stresses, the balanced person is able to respond with energy and strength. When no situation is pressing, the balanced person can comfortably choose to rest and can sleep peacefully.
