Twisting poses are very much an integral part of the pantheon of yoga asanas. Yogis are constantly twisting into intricate poses, holding them as they breathe deeply, and counter-twisting many of them.
But why all the twisting? Because twisting postures have amazing effects on the physical body and even on the mental and emotional ones.
First of all, they’re highly detoxifying in nature. B.K.S. Iyengar refers to it as the “squeeze and soak” action. When we twist, the organs of detoxification in the abdominal region get a good massage. The organs in the digestive system temporarily get their blood supply cut off when we twist into the pose, and then receive a fresh source of blood when we come out of the twist. The cells detoxify and waste moves out of the system.
