This is important “Pranayama”, breathing exercise and can be practiced after yoga or before meal.
Steps:
1. Sit in ‘padmasan’.
2. Take a deep breath.
3. Exhale with OM.
Remember that ‘OOOO‘ should be shorter than MM. Later, ‘MMMMM‘ should sound like to bee. You can stretch bee should as much as you can. This is helps the brain neuron to become more active. This pranayama is useful for kids and adults for more energy, create better focus and better clarity of the mind
This also help reducing heart disease, blood pressure, diabetes, sleep problem, improve brain functioning (both slow thinking or hyper-activeness).
I am referring to Dr Hemant Bhargav, a physician and yoga expert, said. “The OO should be chanted for five seconds and the MMMM should take 10 seconds,” he says. On the screen we can see my brain’s blood oxygen level — and thus activity — fall as I chant, then rise as I rest. Bhargav’s concluded, “my mind is more restful when I chant than when I’m silent.”
