Researchers from Boston University School of Medicine recently discovered practising yoga can help boost GABA levels in the brain. GABA - gamma-aminobutyric acid - is a neurotransmitter which helps the brain calm down and focus.
The study found that those practising yoga three times a week for an hour had higher levels of GABA than those who just read a book.
The team used magnetic resonance spectroscopic imaging to compare levels of the natural valium in volunteers' brains.
The results proved that yoga could be used to help fight anxiety and depression.
The full findings are published online in the Journal of Alternative and Complementary Medicine.
