The Practice of Hatha Yoga Has Great Benefits to the Different Systems of our Bodies

Did you know there are 60,000miles of blood vessels in your circulatory system? Also, are you aware that the complete cycle for a blood cell from the heart through the body back to the heart takes less than one minute?  A well-balanced yoga class will provide moderate exercise for the heart muscle during the active part of the class and complete relaxation at the end of class. This balance of moderate work and complete rest is an ideal program for a healthy heart.

Did you know that the endocrine system regulates the secretion of important chemicals into your body’s blood stream? The chemicals have important functions like regulating the fight or flight response. Like all of the systems of the body, the endocrine system is designed to have periods of activity and rest. If this system is operating on red alert status all of the time the glands can be affected. The thyroid can lose its ability to secrete sufficient amounts of thyroxin. The adrenal glands can loose their ability to secrete adequate amounts of adrenaline and the pancreas can loose its ability to secrete adequate amounts of insulin. Yoga balances the endocrine system as a whole by balancing the mind, which then sends a message of balance to the pituitary, the master gland of the endocrine system. The yoga postures have a direct massaging and balancing effect on all the different endocrine glands.

The muscular-skeletal system of the body is designed to provide strong support and free
movement to our frame. Chronic stress, tension and inactivity can limit the body’s natural movement. When the muscles are chronically contracted through physical or emotional trauma, poor posture, and such, the skeleton loses its natural alignment. This may cause wear and tear and conditions such as osteo-arthritis and other chronic pain symptoms. As the muscular system comes back into balance through yoga, healthy alignment of the skeleton occurs, strength and flexibility return and this allows the muscular-skeletal system to be pain free and move with ease through the day.

For a strong immune system the yoga postures, the breathing exercises, the relaxation and meditation practices are fantastic tools. As we know, a strong immune system fights off invaders that can make us sick from invading bacteria or viruses, causing flus, colds etc. Our immune system can also be over working and producing too much mucus, which creates allergy symptoms like, inflamed eyes, headaches, stuffy ears, nose and difficult breathing. Through postures done in a relaxed way, slow, deep breathing and deep relaxation techniques we can calm and settle the nervous system which informs the  immune system to stop attacking foreign bodies and decrease the amount of mucus being produced. Our symptoms may subside.

There are more systems at work in our bodies including our respiratory and digestive systems. It’s important to remember we are taking care of a whole large multifaceted system that is designed to work synergistically, in harmony with all of its parts, in order to experience optimum wellbeing.  The essential teaching of Yoga is Unity Consciousness, bringing things together, joining all of the systems into balance. This integration is key to the positive benefits that we receive from a regular yoga practice. As our awareness in this deep interconnectedness grows, we can experience a reconnection to the sacred in everyday life and we will truly delight in the joy of being alive.

Yoga Helps Our Respiratory System

If you practice yoga you know that nearly every aspect of yoga is intricately linked to the breath. If you haven’t tried yoga yet, when you do, you will learn that the breath is synonymous with Prana, the vital life force energy that animates us. The ancient art and science of yoga puts great importance on the breath because it is what sustains all our basic life functions.

The job of the respiratory system is to bring oxygen -rich air into the lungs, which is picked up by red blood cells and pumped by the heart to every cell in the body, providing vital oxygen essential for life. Though humans can survive for sometime without food and water, tissues immediately begin to die when deprived of oxygen. Breath is related to all aspects of physiological functioning including cardiovascular functioning, brain circulation, metabolic activity, endocrine activity, muscle and vascular tone, lymphatic drainage and homeostatic regulation.

A regular yoga practice will give you the time to be more aware of breathing and to actually spend time breathing deeper than you might in normal everyday activity. In yoga you are taught how to use your breath to help relax the body and to control the breath even when the body is active. You are taught how to synchronize the breath with your movement. Some classes will spend time just with particular breathing exercises, pranayama, with the intention to balance the autonomic nervous system, the right and left hemispheres of the brain, and to increase the breathing capacity, which helps expel carbon dioxide and other waste products.

The effects of yoga on asthma are one of the areas that researchers have spent time studying. These studies done at yoga institutions in India have reported impressive success in improving asthma. Physicians have found improvement in anxiety associated with asthma using yoga postures, breathing and meditation techniques. You can Google yoga research on asthma and find many articles are available showing the positive findings.

Guided visualizations and relaxation techniques that focus on calming the entire respiratory system can be extremely helpful to people with breathing conditions like asthma, bronchitis, and emphysema. Putting people in a comfortable position and bringing their attention to their breathing can increase the awareness of how the breath is flowing. Is it shallow or deep? Is it smooth? Are both the diaphragm and the chest muscles moving? Is it noticeable at the nostrils? Using visualization that leads them through their own system from the air entering through the nose into the trachea, down the bronchial tubes all the way into the alveoli, with suggestions to see healthy, receptive, relaxed oxygen exchange happening within can create quiet, peaceful breathing and be a great relief.

How we breathe has important effects on our overall health. Here is an excerpt from The Journal of The International Association Of Yoga Therapists, Vol.2, No. 1, 1991, pages 13-17. This is written by Richard C. Miller, Ph.D. in his article, “The Psychophysiology of Respiration: Eastern and Western Perspectives.”

With slow, rhythmic, abdominal-diaphragmatic breathing, relatively high levels of CO2 accumulate in the lung arterioles and the blood. As a result, blood pH shifts towards acidosis, triggering numerous psycho physiological processes. Increased CO2 induces relaxation of vascular tone, promotes coronary and cerebral blood flow, oxygenation of the heart and brain, removal of acidic metabolites, and an increase in oxygen transfer from hemoglobin to cellular tissues.

He goes on in much more detail, but the message is clear that respiration, how we breathe, has a large influence on our general well being.

This brings us back to where we started. If you practice yoga, you have experienced the emphasis that is brought to coordinating breath and movement together. The link to our Prana, or life force energy, is a great reason for choosing it as a self-care method. If you haven’t tried yoga yet, well, what’s stopping you??
