Yoga to refresh yourself: Sit straight. Create hooks with your hands and then lock them together at chest level. Keep lower arms parallel to ground, twist upper body and head first to the left, then to the right. Inhale as you turn to left, exhale as you turn to right. Continue for 1 to 3 minutes. Please ask your doctor if this exercise is suitable for you. Get the most out of every cup. Bring water just to boiling and steep 3 minutes. For a stronger tea, use 2 tea bags. Drink 3-4 cups daily.
