​In our present day busy lifestyle, we tend to ignore our breathing, resulting in fast and shallow breathing. We use only a fraction of our lung, which decreases the total lung capacity and in the long run, leads to complications like heart diseases, sleep disorders and fatigue.

Pranayama essentially means breath control. Involves deep inhalation and exhalation.


Meditation is a means of transforming the mind. You learn the patterns and habits of your mind cultivate new, more positive ways of being. It helps one develop concentration, clarity, calmness, emotional positivity, and understand the true nature of things.

Meditation is like mild exercise for your nerves and your brain. Meditation brings in inner peace and harmony and helps in stress reduction boosting our immune system. Meditation need practice and guidance initially.

Meditation reactivates nervous system; stabilizing most mental illnesses and even curing them.

Listen to yourself and listen to your body when practicing yoga – Do Not Force yourself. Start slowly and progress gradually.

People with spinal disorders (herniated disc, spine surgeries, scoliosis etc…) should not practice postures, which involve bending of the spine.

Yoga was introduced in America in the 1800s by Swami Vivekananda (a well renowned Indian Monk) when he addressed at the “Parliament of Religions” in Chicago and discussed about meditation

Deep inhalation (Breathe in) allows oxygen flow to different parts of the body – recharging the body. Deep exhalation (Breathe out) pushes out carbon di oxide which eliminates toxic wastes from the body. The balance of oxygen and carbon di oxide is achieved by pranayama. Pranayama increases total lung capacity.

Pranayama helps decrease asthma flare-ups, helps with prevention and cure of nasal allergies, sinus problems and bronchitis.

It also helps achieve self-control and sharpens intellect.

Pranayama should not be forced upon – it must be started slowly and increased gradually over a period as per individual tolerance.


Before proceeding with the health benefits lets discuss physiology behind this age old practice of self-discipline.

Cell is the most basic structure of any living organism. Human body is made up of trillions of cells. Cells get regenerated on a regular basis. Various yogic postures make the body flexible providing uniform blood supply to all body parts. With good blood supply cells are adequately nourished, aiding new cell formation.

Digestive system – Our health is directly linked to our digestive system. Improper functioning of our digestive system is the prime cause for most of our diseases. Different yogic exercises strengthen the digestive system by strengthening the abdominal muscles, intestinal motility improves which helps treat common ailments like constipation, flatulence, bloating, acid reflux etc..

My Suggestions

Yoga is a light intensity workout. Yoga must always be combined with good aerobic and balanced diet. Diet has effect not only on the body but on the mind too. Fill half of your stomach with food, a quarter with liquid and leave out a quarter for air, avoid irregular eating. Early to bed and early to rise contributes to good health. A diet rich in natural fresh produce purify the blood and help nourish cell reconstruction. Most of the common ailments are self-made which need to be fixed from within. Yoga, pranayama and meditation helps in a big way.
