 Yoga practicing may have a profound effect in improved immune function against foreign invasion, particularly in age-related immune suppression in elderly individuals

Immune function is a natural reaction of immune system in protected our body against from foreign substances, cells, and tissues through proper expression of immune response.

Yoga, the ancient technique practice for harmonized external and internal body well beings, through breath control, meditation, bodily movement and gesture..... has been best known for people in Western world and some parts in Asia due to health benefits reported by various respectable institutes' research and supported by health advocates.

In the study to evaluate the effect of yoga on mucosal immune function and mental stress with saliva samples collected from 23 adult women (age: 60.4 ± 10.4 years) before and after 90 minutes of yoga stretching or rest, researchers found that
1. Yoga group expressed a significant higher immunoglobulin A (SIgA)(a subclass of Immunoglobulin A (IgA) plays an important role in the immune function of mucous membranes)
concentration and secretion rate after yoga than before and in compared to control
2. The levels of cortisol( higher levels cortisol caused by stress has a negative effect in immune system) concentration and secretion rate were lower and testosterone(which plays an important role in immune function in reduced risk of autoimmune disease) secretion rate higher after yoga.
After further analysis and taking into account of other co founders, researcher said, " Yoga stretching can reduce stress and enhance mucosal immune function in elderly women."

Mucosal immune function is a first line of defense of immune system against antigens and infection and in regulated immune over reaction from unharmful sources.

According to general belief, yoga twist, compress and standing posts exercise play an important role in ameliorated alterations in the number of immune cells and cytokine dysregulation through lowering stress hormones production.

Additionally, the exercises also found to improve energy and energy balancing in the body which are necessary for immune system to function properly.

In the concerns of yoga expression in enhanced immune system through numbers of mechanism, researchers at the Daejeon University conducted a study in healthy adults, to highlight the beneficial effects of yoga practice on bio-parameters related to immune expression found that
1. Yoga group expressed a significantly reduced levels of relative oxygen species(ROS), including include peroxides, superoxide, hydroxyl radical, and singlet oxygen through regulating cellular metabolism in production of ROS which have been found to have a direct influence in T cells activation, apoptosis, and immune hypo responsiveness.2. Yoga group demonstrated  a improvement of immunity in increased levels of antioxidant in compared to control, through the effects of free radical scavengers in reduced cellular damage caused by over expression of ROS in inducing inflammation.
3. Yoga practice also significantly increased immune-related cytokines, such as interleukin-12, and interferon-γ,....which play an important role in reduced risk of inflammatory and auto immune diseases, including diabetes, atherosclerosis, rheumatic arthritis, and cancer.
4. The levels of plasma levels of adrenalin was reduced  and serotonin was increased in yoga group in compared with the control group.

Elevation of plasma levels of adrenalin caused by stress may suppress the immune system and increased levels of serotonin showed a opposite effect in increased killing ability of natural killer (NK) cells.
After taking into account of other co founders, Dr. Lim SA, the led researcher said, "Regular yoga practice remarkably attenuated oxidative stress (caused by imbalance of between the production of free radicals and antioxidants) and improved antioxidant levels of the body. Moreover, yoga beneficially affected stress hormone releases as well as partially improved immune function."
More importantly, in the review on the effects of yoga poses on psychological conditions including anxiety and depression, on pain syndromes, cardiovascular, autoimmune and immune conditions and on pregnancy., Dr. Field T, at the University of Miami School of Medicine, opinionated that yoga intervention induced the less production of cortisol, the hormone has a negative effect on immune system due to stress may indeed have a profound effect in enhanced immune cellular function, particularly in psychological conditions in regulating the autoimmune and immune conditions.

Taking altogether, There is no doubt that yoga practice may have a therapeutic effect in improved immune function against from foreign substances, cells, and tissues through numbers of mechanism involving different pathways.
