The 12-week yoga intervention was associated with greater improvements in mood and anxiety than a metabolically matched walking exercise. This is the first study to demonstrate that increased thalamic GABA levels are associated with improved mood and decreased anxiety.
After the CBT + kundalini yoga intervention, pre-post comparisons showed statistically significant improvements in state and trait anxiety, depression, panic, sleep and quality of life.
This study aimed to evaluate the effect of yoga on back pain, BDNF and serotonin of pre-menopausal women who practiced yoga 3X a week for 12 weeks.
