Yoga can help you fight depression, boost brain chemicals that regulate mood

Yoga is not just good for the body, it can also help you cope with depression by reducing its severity and increasing levels of chemicals in the brain that maintain the sleep-wake cycle and regulate mood, says this new study.

Yoga helps reduce the severity of depression by increasing levels of certain chemicals in the brain that maintain the sleep-wake cycle and regulate the mood, appetite and digestion, according a recent study by the All India Institute of Medical Sciences (AIIMS).

The study found that introducing yoga into lifestyle results in a decrease in cortisol, the main stress hormone, and reduces levels of certain inflammatory molecules in the body as well as the brain, thereby reducing oxidative stress, said Rima Dada, Professor in-charge of Laboratory of Molecular Reproduction and Genetics, Department of Anatomy at AIIMS. It also slows the pace of ageing by reducing levels of oxidative and psychological stress and aids in maintaining the length of telomere, Dada said.

Telomeres are DNA sequences which lie at the ends of chromosomes and act as a biological clock. The study, which was published in the Restorative Neurology and Neuroscience journal in March, found that meditation and yoga could reduce severity of depression and lead to improvement in systemic biomarkers of neuroplasticity.

It affects all age groups and is the leading contributor to global burden of disease. Though about 35% cases are hereditary, depression can be the cause and consequence of several non-communicable diseases such as cancer, diabetes, nutritional and substance abuse disorders. Adverse childhood events also play a major role in its causation, Dada said.

Depression disrupts the body’s protective regulatory mechanisms and damage the genetic make-up and cell functions. Most importantly, it disrupts the mechanisms that regulate the way your body responds to stress. Moreover, the immune system becomes hyperactive and aggravates the damage to organ systems including the brain.

“While medication and psychological interventions are first-line treatments for depression, they provide suboptimal remission and are associated with frequent relapses and complications. Treatment of depression by yoga enhances physical and mental well-being,” said Dada.
