How Yoga Calms the Mind and Body

Yoga is famous for its ability to heal and bring peace of mind. But how does the practice of yoga accomplish this?

There are two nervous systems in the human body: sympathetic and parasympathetic. The sympathetic, commonly known as the "fight or flight" system, causes the blood pressure to rise, the breath rate to quicken, and stress hormones to flood into the body. Historically, this occurred to prepare the body for fighting dangerous animals. But in today's world, we experience this response while we are sitting in traffic or feeling stressed at the office. When this system is overly stimulated, we can experience health consequences such as ulcers, migraines, and heart disease.

The parasympathetic nervous system lowers blood pressure and slows the pace of the breath. When the blood no longer has to rush to the muscles, it is free to travel to the digestive, reproductive, glandular, and immune systems made up of organs that are more necessary to long-term survival. The body now has time to heal the damage accumulated during our daily battles. Studies have shown that long, deep breathing encourages the actions of the parasympathetic nervous system and allows relaxation and healing to occur. The yogi practices breathing meditations called pranayama, which encourage the actions of the parasympathetic nervous system.

The quality of the breath reflects the quality of the mind. There is a connection between our mental, emotional, and psychological states and the pace and depth of our breath. For example, when we are frightened, we take short, quick, shallow breaths. When we are deeply relaxed or asleep, we take long, deep breaths.

While our mental state influences our breathing pattern, we can choose to change our breathing pattern and thereby change our mental state. When you relax and slow the pace of the breath, the pace of the mind is similarly calmed and quieted. Over time, you begin to act and think from a state of peace. The more time you spend in this place, the more likely you are to act with patience, understanding, and compassion.

The breath also helps us to stay connected to the present moment. Staying in the now frees us. We can move on from past grievances and sorrows and can view the world as it really is, without false expectations. We learn to accept ourselves and others as we and they currently are. Being in the moment allows you to be fully present when you spend time with the people you love.
