How Yoga Improves Health: Focus on Chronic Inflammation
Inflammation is part of the body’s defense response. It involves clearance of toxic pathogens, damaged cells, or harmful irritants from the body.
Inflammation has a high beneficial value. For example, if you develop a viral infection or if your back sustains a severe blow, inflammation sets in to care and protect the injured tissue and initiate a healing response.
The classical signs of inflammation are pain, heat, redness, and fluid accumulation (swelling), and reflect the activation of the body’s defensive strategies that ward off the damage and heal the injured area. The defensive strategies are carried out by leukocytes, macrophages, dendritic cells, mast cells, bradykinin, histamine, interleukins, and TNF, among others.
In a perfect setting, the inflammatory process occurs just as it should, releasing defense/pro-inflammatory molecules when needed and then turning them off when the threat has been sufficiently addressed.
Chronic inflammation, on the other hand, is characterized by an aberrant, out-of-control defense response and is akin to a constant slow-burning fire. In chronic inflammation the defense/pro-inflammatory molecules continue to be present in the body even when they are not needed and the body operates as if it is constantly under attack. Thus, chronic inflammation continuously draws on your body’s energy and resources, which can result in bodily damage with time. Furthermore, as the system goes out of control, it self-perpetuates and triggers severe disease conditions, including, atherosclerosis (inflammation in blood vessels), diabetes (inflammation in pancreatic tissue), arthritis (inflammation in bones and joints), celiac disease (inflammation in digestive system), fibromyalgia, neuralgia (inflammation in limbs, muscles and nerves), and ankylosing spondylitis (inflammation in the spinal region), among others.
In addition to the factors that influence inflammation that I outlined in my previous post, today I’m updating that list to include:
This is now considered a heightened state of chronic inflammation because of the elevated plasma levels of several pro-inflammatory markers. It is believed that fat cells (adipocytes) themselves trigger the release of a number of these markers in the bloodstream.
People who are physically very active have lower levels of inflammatory biomarkers than their sedentary counterparts, so physical fitness is inversely associated with inflammation.
Emotional disorders, including anxiety and depression, can trigger inflammation and elevate the levels of pro-inflammatory molecules.
Chronic stress can directly provoke increases in proinflammatory cytokines.
Furthermore, inflammation is now regarded as a risk factor for most cancers as well because of the recent evidence that inflammation influences cancer cells to grow, survive and proliferate. Scientists believe that cancer treatment procedures trigger the inflammatory process that fails to turn off. In addition to the weakness and pain from the cancer therapy procedures, cancer patients now suffer from inflammation that draws on their body’s resources, resulting in chronic fatigue. It’s as though the body’s defense system fails to distinguish its own self thus making the body vulnerable to attacks from its own cellular system.
Yoga can help with all these factors. It can help in controlling obesity by making correct choices of our eating habits, in controlling stress and emotions. And in a landmark study in the Journal of Clinical Oncology, researchers showed that cancer survivors who had a regular yoga practice: (a) reported less fatigue and higher levels of vitality, (b) showed reduced levels of several pro-inflammatory molecules in the body, (c) reported less pain and less inflamed joints, and (d) demonstrated significantly improved sleep. This study not only offered biological evidence of the benefits of yoga, in addition it substantiated people's own reports of their improvement.
Yoga and yoga-related practices, including meditation, affect cellular processes at many levels that result in immense health benefits. While most of the health benefits may not appear immediately, all the benefits of yoga may become evident with a sustained and regular practice. So the next time you visit your doctor and are told that you have an inflammatory condition, think of yogic management practices.
