Mind-body interventions (MBIs), such as meditation, yoga and tai chi, dont just relax us. According to a new study, they can reverse the molecular reactions in our DNA that cause ill health and depression. <\/p>\n
The research, published in the journal Frontiers in Immunology, reviews over a decade of studies analyzing how the behavior of our genes is affected by different MBIs, including mindfulness and yoga. <\/p>\n
Researchers at Coventry University in the U.K. and Radboud University in the Netherlands conclude that, when examined together, the 18 studies featuring 846 participants over 11 years reveal a pattern in the molecular changes that happen to the body as a result of MBIs, and how those changes benefit our mental and physical health. <\/p>\n
The researchers focused on how gene expression is affected in other words, the way that genes activate to produce proteins that influence the biological makeup of the body, the brain, and the immune system. <\/p>\n
When a person is exposed to a stressful event, their sympathetic nervous system, which is responsible for the fight-or-flight response, is triggered, which increases production of a molecule called nuclear factor kappa B (NF-kB), which regulates how our genes are expressed, the researchers explained. <\/p>\n
NF-kB translates stress by activating genes to produce proteins called cytokines that cause inflammation at a cellular level, a reaction that is useful as a short-lived fight-or-flight reaction, but if persistent leads to a higher risk of cancer, accelerated aging, and psychiatric disorders like depression, the researchers noted. <\/p>\n
However, people who practice MBIs exhibit the opposite effect a decrease in the production of NF-kB and cytokines, leading to a reversal of the pro-inflammatory gene expression pattern and a reduction in the risk of inflammation-related diseases and conditions, according to the studys findings. <\/p>\n
The inflammatory effect of the fight-or-flight response, which also serves to temporarily bolster the immune system, would have played an important role in mankinds hunter-gatherer prehistory, when there was a higher risk of infection from wounds, the researchers said. <\/p>\n
Today, however, where stress is increasingly psychological and often longer-term, pro-inflammatory gene expression can be persistent and more likely to cause psychiatric and medical problems, they noted. <\/p>\n
Millions of people around the world already enjoy the health benefits of mind-body interventions like yoga or meditation, but what they perhaps dont realize is that these benefits begin at a molecular level and can change the way our genetic code goes about its business, said lead investigator Ivana Buric from the Brain, Belief and Behavior Lab in Coventry Universitys Centre for Psychology, Behavior and Achievement. <\/p>\n
These activities are leaving what we call a molecular signature in our cells, which reverses the effect that stress or anxiety would have on the body by changing how our genes are expressed. Put simply, MBIs cause the brain to steer our DNA processes along a path which improves our well-being. <\/p>\n
She added that more needs to be done to understand these effects in greater depth,for example how they compare with other healthy interventions like exercise or nutrition. <\/p>\n
But this is an important foundation to build on to help future researchers explore the benefits of increasingly popular mind-body activities, she concluded. <\/p>\n
