All yoga exercises are aimed at mental discipline and the harmonisation of body and mind. Control of the breath (Pranayama) plays a crucial role to reach inner balance and self-realisation. The practice of Pranayama will contribute to well-being and a happy life. The exercises increase the supply of oxygen to the body, revitalizing and supporting the healing of diseases and injuries. They can also be used to improve or ease difficult situations as they calm the mind, which will become more resistant to stress and depression. During pregnancy specific exercises support the welfare of mother and child and can help with an easier birth. Free divers can improve their performance and dive more safely when they practice Pranayama regularly. Musicians, singers, professional speakers and teachers can also find several of the breathing exercises helpful.
