The Head to Knee Pose balances blood sugar levels and improves flexibility in the sciatic nerve, ankles, knees, hips and wrists. It improves digestion, kidney function and strengthens the solar plexus. Holding this position helps chronic digestive problems by increasing blood circulation in the bowels; blood also flows into the internal organs (liver, spleen, pancreas, thyroid, thymus and intestines). This pose increases flexibility of the deltoid and trapezoid muscles, biceps, sciatic nerve and hips. The combination of both positions is excellent for the immune and lymphatic systems and helps arthritis.
