The Power of the Central Nervous System in Alleviating Stress ~ Reset & Stop the Fight or Flight Hormone

Mar 10, 2022



How It Affects Our Central Nervous System


The Nervous System is a complex network of nerves (neurons) that are interconnected with one another. It is comprised of the Central Nervous System (CNS), which includes the brain and the spinal cord, and the Peripheral Nervous System (PNS), which is a large network of nerves. The Nervous System responds to external and internal stimuli. The neurons use electrochemical signals to give specific instructions to various parts of the body on how to react to a specific stimulus.

Stress stimulates the CNS and prepares it to meet stressful situations. During this preparation, the body goes through various physiological changes that are initiated to enable the fight or flight response. This is the function of the Autonomic Nervous System, which is comprised of the Sympathetic Nervous System and the Parasympathetic Nervous System. The Sympathetic Nervous System is responsible for stress responses, while the Parasympathetic Nervous System prepares the body for rest and relaxation.

When an event in our lives causes fear, dread, or terror; the Sympathetic Nervous System senses the danger and increases the heart rate to send an extra supply of blood to different parts of the body. It also signals the Adrenal Glands near the Kidneys to secrete adrenaline, the hormone that provides a boost to muscular energy. The Nervous System is very different from other systems in the body. It not only supervises stress but also controls the body’s reactions afterward. It reduces the level of hormones in the bloodstream and signals the heart to revert back to its normal beat rate.

 Emotional stress produces similar physical changes by stimulating the Nervous System to respond. Even though we know that adequate and relevant responses to stress are necessary, the state of the body during these conditions is not normal. The body comes into a stressed state almost instantly when it detects any kind of threat, but the body must necessarily revert back to its normal state after a certain period of time. Reverting back to the normal state is not possible when there is constant stress. 

This can have a dramatic effect on our health over time. Constant stress means that the Sympathetic Nervous System keeps us in a state of alert all the time and does not let the Parasympathetic Nervous System come into play. This translates into a situation where the body cannot actually rest at all. If the body is not at rest, the body systems that are suspended during the stress response cannot be resumed effectively.

 Admittedly, it is impossible to avoid stress completely. However, we can manage stress through various Relaxation Techniques. Setting aside time for Deep Breathing throughout our day can bring about greater relaxation.  Yoga and meditation send signals to the Central Nervous System that help the body to return to its original relaxed state. Managing emotional stress by re-evaluating our perception of life situations can also have a very positive effect on the Nervous System. Positive thinking is an incredibly effective way to reduce stress and may help us to adapt and manage stress as it arises. Massage Therapy is an excellent way to allow the body time to reach a state of deep relaxation. CranioSacral Therapy can reset the CNS. This affects relaxation at the deepest center of our physical system; relaxing and balancing our CNS, resetting every system in the body. When we are able to reset the CNS it is like rebooting our computer. It reboots every system as the CNS governs every system in the body. Stress is going to come and go in our lives. How we choose to respond to it is ours to determine.


 Benefits of Reseting The Central Nervous System: 

How It Affects Our Bodies And Our Health
  1. The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components:

    1. The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.

    2. The brain is responsible for integrating most sensory information and coordinating body function, both consciously and unconsciously. Complex functions such as thinking and feeling as well as regulation of homeostasis are attributable to different parts of the brain.

  2. The brain and spinal cord share some key anatomic features:

    1. Living nervous tissue has the consistency of jelly and requires special protection from physical damage. The entire CNS is encased in bone. The brain is within the cranium, while the spinal cord runs within a canal through the vertebrae.

    2. Within its bony case, the entire CNS is bathed in a cerebrospinal fluid (CSF), a colorless fluid produced by special structures in the brain. CSF provides a special chemical environment for nervous tissue, as well as an additional buffer against physical damage.

    3. The special chemical environment of nervous tissue is maintained by the relatively impermeable membranes of capillaries in the CNS. This feature is known as the blood-brain barrier.

    4. There are two general types of tissue in the CNS:

      1. Gray matter consists of nerve cell bodies, dendrites, and axons. Neurons in gray matter organize either in layers, as in the cerebral cortex, or as clusters called nuclei.

      2. White matter consists mostly of axons, causing it to look white due to the myelin sheathing of the axons.

  3. In the early embryo, the CNS forms as a relatively uniform tube. The major regions of the brain develop as enlargements at the head end of this tube:

    1. The medulla oblongata appears as a swelling at the upper end of the spinal cord. Besides being a conduit for fibers running between the spinal cord and higher regions of the brain, it contains control centers for involuntary functions such as blood pressure, breathing, swallowing, and vomiting.

    2. Just above the medulla are the pons and cerebellum. The pons relays information between higher regions of the brain and the cerebellum, which processes sensory information and helps coordinate movement.

    3. The next segment, the midbrain, is primarily responsible for eye movement.

    4. Above the midbrain lies the diencephalon, which is composed of two major parts:

      1. The thalamus processes and integrates all sensory information going to the higher regions of the brain.

      2. The hypothalamus is critical for homeostasis, the maintenance of the body's internal environment. It influences nervous control of all internal organs and also serves as the master regulator of endocrine function by its control over the pituitary gland.

    5. The highest region of the brain is the cerebrum, which includes both the cerebral cortex that is visible on the outside of the brain as well as other internal structures. The cerebrum is responsible for conscious sensation and voluntary movement, as well as advanced functions such as thinking, learning, and emotion.


      As you can see the Central Nervous System is a very complex yet powerful source of our daily well-being. In short, these are just some of the benefits of CNS Reset. 

      • Improved sleep and mood
      • Improved heart rate variability
      • Decreased anxiety, emotional reactivity, depression, and hypervigilance
      • Improved appetite, digestion, and elimination
      • Improved emotional resiliency
      • Increased quieting of the mind and deepening of relaxation
      • Increased awareness of body, mind, emotion, and Spirit
      • Increased flexibility, mobility, and range of motion
      • Increased sense of connection with self and others
