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.

The Scientific Basis of How Yoga Works -- Science of Us

If you’re doing the same poses over and over again, day after day, year after year, you’re going to get pretty intimate with how your body expresses itself in those forms, and along the way cultivate what researchers call proprioception, or the awareness of where your body is in space, and interoception, or the sensations not just of the air on your skin, but your bones, tendons, and body tissues as you mindfully contort your body, as well as your emotional state. As your yoga teachers have exhorted you to do, you’re gaining a finer-grained sense of where your skeleton is within your body, and how all the flesh layers on top of that. As Harvard Medical School assistant professor Sat Bir Singh Khalsa told me, these increases in internal awareness can change entire lifestyles. “Somebody’s who’s practiced yoga for eight weeks and then smokes a cigarette, will say, ‘My god, I never noticed how bad these things were, I can’t stand this, this feels awful,’” he says. With training, the body’s sensations become more perceptible to you, so you feel the toxicity of things at a higher intensity. For this reason, he says, yoga can be super powerful in controlling lifestyle diseases. “People change their diets, change their behaviors to ones that make them feel better, because now, for the first time in their lives, they’re actually feeling more.”
