Basic guidelines for enacting healthy, conscious breathing: Sit with a naturally good posture without straining any muscles.Inhale and exhale through the nose with the mouth closed.Breathe deep and slow without forcing your inhales or exhales.Breathing should be smooth and naturally rhythmic.
Fill your lower lungs first, then mid-lungs and your upper lungs last..Allow natural pauses to happen between each inhale and exhale.or just relax and enjoy the space ,its not really rocket science .
