That, of course is breathing.
Breathing is something all people do, but doing it correctly is quite another matter.
Practicing controlled yogic breathing, or Pranayama is a very valuable technique that leads to a better and healthier lifestyle. There are several breathing techniques that can be utilized to relax one's body and mind. Some of these include simple breathing, alternate nostril breathing, and complete breathing. Simple breathing is a great technique to start out with because it is the base of all the other breathing techniques. It can be used not only to become aware of one's breath, but relieve the tension accumulated from a long day at school or work.
