A newly published study has found that the regular practice of yoga can lower the levels of pro-inflammatory cytokines in the blood stream. Cytokines are signalling molecules that regulate the various cellular components of inflammation, an immune-based response to threat (physical or psychological). Long-term inflammation contributes to many health conditions including cardiovascular diseases, arthritis, and asthma.
In this study conditions of stress were implemented through tasks such as holding their bare foot in very cold water, or solving increasingly difficult math problems without a calculator. The researchers also found that those who practiced yoga had less dramatic responses (less increase in cytokine activity, less self-reported anxiety and stress) to the stressors.
The results of this study speak to the wide-ranging benefits of yoga, and other relaxation techniques. This study also highlights the fact that we can train ourselves to have less severe reactions to stressors in our lives. Over time these benefits can really add up, resulting in long-term improvements in physical and mental health.
