Inhale, exhale... and once again
Breathing or Prana / "Pranayama is the control and extension of the breath which awakens Prana (life force energy). Practicing the way you inhale and exhale can help you manipulate your vital energy to successfully activate or soothe your mood." In simpler terms becoming more aware of your breathing and body, which allows you to move deeper into a pose. In all my classes I tell the client that once you become aware of how your inhale and exhale finding a deeper breathe off the mat will be second nature.
There are many styles of Prana, not all are comfortable to everyone. An example is belly breathing air enters the lungs and the belly, for this reason may have asked to not use this style. Breathing air into your belly means the air must leave your body, which can result in belching or passing gas. Both are natural for us but not comfortable to do in front of others. Have no fear we have many breathing techniques to choose from...starting with the simple filling and completely emptying of your lungs.
Taking the breathing technique off the mat and into your day to day life can help with stress and concentration. Even the best of us can be caught off guard when the air turns cold or hitting the higher temperatures of summer. Have you ever walked outside from a nice warm house into a cold winters day and have it just steal your breath away? Well go back to your deep inhale and exhale to regulate your internal temperature. Getting your deep breathe back will also start to calm your body from the abrupt change in air temperature. The same goes for a hot day.
I hope this helps,
