Can Qigong have physical effects? Researchers analyzed the effects of Qigong practice on saliva (Bayat-Movahed et al., 2008). They measured the volume, pH and secretory immunoglobulin A (S-IgA) level of the saliva in Qigong practitioners.
A total of 23 healthy volunteers about 24-year old were involved in the study (Bayat-Movahed et al., 2008). These participants had special Qigong training and massaged acupuncture points to promote the energy cycle and body water energy. The researchers measured the saliva volume and pH before and after the volunteers practiced Qigong.
The study showed that the saliva volume and S-IgA level after Qigong exercises were remarkably increased, compared with those before the exercise (Bayat-Movahed et al., 2008). The researchers did not find obvious changes in the pH levels.
The study indicates that Qigong training may have its health effects through promoting salivary volume and other parameters (Bayat-Movahed et al., 2008). Such results suggest that Qigong may be helpful for those who have the problem of salivary hyposecretion. More studies and larger scale clinical trials are needed to study the mechanisms of Qigong and how these mechanisms can be used for disease treatment.
