REDUCING ANXIETY AND DEPRESSION: Yoga can greatly improve your aliveness and mental health.
Read what the latest research is saying:
Researchers at Boston University School of Medicine (BUSM) and McLean
Hospital have found that practicing yoga may elevate brain
gamma-aminobutyric (GABA) levels, the brain's primary inhibitory
neurotransmitter. The findings suggest that the practice of yoga be explored
as a possible treatment for depression and anxiety, disorders associated
with low GABA levels.
The World Health Organization reports that mental illness makes up to
fifteen percent of disease in the world. Depression and anxiety disorders
both contribute to this burden and are associated with low GABA levels.
Currently, these disorders have been successfully treated with
pharmaceutical agents designed to increase GABA levels.
Using magnetic resonance spectroscopic imaging, the researchers compared the
GABA levels of eight subjects prior to and after one hour of yoga, with 11
subjects who did no yoga but instead read for one hour. The researchers
found a twenty-seven percent increase in GABA levels in the yoga
practitioner group after their session, but no change in the comparison
subject group after their reading session. The acquisition of the GABA
levels was done using a magnetic resonance spectroscopy technique developed
by J. Eric Jensen, PhD, an assistant professor of psychiatry at Harvard
Medical School and an associate physicist at McLean Hospital.
According to the researchers, yoga has shown promise in improving symptoms
associated with depression, anxiety and epilepsy. "Our findings clearly
demonstrate that in experienced yoga practitioners, brain GABA levels
increase after a session of yoga," said lead author Chris Streeter, MD, an
assistant professor of psychiatry and neurology at BUSM and a research
associate at McLean Hospital.
"This study contributes to the understanding of how the GABA system is
affected by both pharmacologic and behavioral interventions and will help to
guide the development of new treatments for low GABA states," said co-author
Domenic Ciraulo, MD, professor and chairman of the department of psychiatry
at BUSM.
"The development of an inexpensive, widely available intervention such as
yoga that has no side effects but is effective in alleviating the symptoms
of disorders associated with low GABA levels has clear public health
advantage," added senior author Perry Renshaw, MD, PhD, director of the
Brain Imaging Center at Harvard-affiliated McLean Hospital
