Yoga, meditation improve brain function and energy levels, study shows -- ScienceDaily

Thirty-one study participants completed 25 minutes of Hatha yoga, 25 minutes of mindfulness meditation, and 25 minutes of quiet reading (a control task) in randomized order. Following both the yoga and meditation activities, participants performed significantly better on executive function tasks compared to the reading task. "This finding suggests that there may be something special about meditation -- as opposed to the physical posing -- that carries a lot of the cognitive benefits of yoga," said Kimberley Luu, lead author on the paper. The study also found that mindfulness meditation and Hatha yoga were both effective for improving energy levels, but Hatha yoga had significantly more powerful effects than meditation alone.
