Cytokines are inflammatory proteins that your body secretes to control and direct immunity and inflammation.
Some of these cytokines are responsible for lowering pain threshold, thereby making it easier to hurt. These same cytokines have receptors in the brain that are associated with "sickness behavior"--the behavior of depression and decreased energy.
It has even been shown that elevated levels of these cytokines can cause clinical depression! A recent study sought to quantify the effects of chiropractic care on these cytokines. After chiropractic treatment cytokine levels fell dramatically. Interestingly, this reduction in pro-inflammatory cytokines was throughout the body, not just in the area of the manipulation!
The result is not only less pain and inflammation, but less depression and more energy. This study is very exciting as it adds to the foundation of how chiropractic effects and improves overall wellness and health.
