The human body is a marvel of intricate systems working in harmony to maintain balance and respond to the ever-changing environment. Two key players in this symphony are the sympathetic and parasympathetic nervous systems. These systems, collectively known as the autonomic nervous system, play a crucial role in regulating involuntary bodily functions. Understanding the differences between these two systems is fundamental to comprehending the equilibrium that sustains our physiological well-being.

Sympathetic Nervous System (SNS):

The sympathetic nervous system, often referred to as the “fight or flight” response, is the body’s rapid-response system to perceived threats or stressors. When activated, it triggers a cascade of physiological changes aimed at preparing the body for immediate action. The release of the neurotransmitter norepinephrine prompts a surge in heart rate, dilation of the pupils, and increased blood flow to muscles, enhancing the body’s ability to confront or escape a threat.

One of the notable effects of the sympathetic nervous system is the stimulation of the adrenal glands, leading to the release of adrenaline. This hormone heightens alertness and mobilizes energy reserves, providing a burst of strength and stamina. Additionally, the sympathetic system inhibits non-essential functions such as digestion, as resources are redirected towards functions vital for survival. Think of the Sympathetic Nervous System as being the body’s gas pedal.

Parasympathetic Nervous System (PSNS):

In contrast to the sympathetic system, the parasympathetic nervous system is often dubbed the “rest and digest” response. Its primary role is to promote relaxation and recovery, conserving energy when the body is in a state of rest. Activated during periods of calm and safety, the parasympathetic system counterbalances the effects of the sympathetic system.

Acetylcholine, another neurotransmitter, is responsible for transmitting signals within the parasympathetic nervous system. When activated, this system slows the heart rate, constricts the pupils, and redirects blood flow towards digestive organs. As a result, the body can focus on processes such as digestion, nutrient absorption, and cell repair. Think about the Parasympathetic Nervous System as being the body’s brake pedal.

Balancing Act:

Maintaining equilibrium between the sympathetic and parasympathetic nervous systems is essential for overall health and well-being. The body’s ability to swiftly switch between these two responses ensures adaptability to various situations. Chronic activation of the sympathetic system, however, can lead to long-term health issues such as high blood pressure, digestive problems, and compromised immune function. Conversely, an overactive parasympathetic system may cause lethargy, digestive issues, and a decreased ability to respond to external stimuli.

6 ways to help balance your Autonomic Nervous System

1. Chiropractic Adjustments – The most commonly missed cause of ANS dysfunction is Subluxation in between the base of the skull and the first bone in the spine, Atlas.  The Vagus nerve, or cranial nerve 10, originates in the brainstem, it exits through this space and extends throughout the body, regulating heart, digestive and lung functions. Only Chiropractic adjustments can correct Subluxation and allow the body to heal and function.
2. Manage your Stress – Stress management can vary from person to person, so the primary strategy is to discover what works for you, specifically. How do you prefer to relax? Schedule that into your day. Whether that means running, dancing, reading, or napping – do what works best for you.
3. Protect your sleep – Shoot for a minimum of 7-8 hours of sleep per night.  Make sure you turn off technology 30 minutes before bedtime and keep the bedroom dark.  Create a healthy rhythm by having a set bedtime and a set time to wake.
4. Exercise – Try to incorporate both high intensity and low intensity exercise into your routine.  Interval training and walking or Rucking is a perfect example.
5. Stay away from stimulants – Sugar and caffeine can be disruptive to your ANS function and should be avoided.
6. Take time to breathe – We recommend “Box Breathing”: Breathe in through your nose for 4 seconds, hold your breath for 4 seconds, breathe out through your mouth for 4 seconds, then hold your breath for 4 seconds.  Repeat this at least 3 times.

Just taking a few steps and starting a few good habits can make all the difference in regaining and maintaining a high level of health, as well as help you become your own doctor!
