Daily Health Tip

Try the tree pose

To build concentration and balance, try doing the tree pose: Stand with your feet directly under your hips, feet parallel. Lift your right foot and rest it on the inside of your left leg, under your knee. Clasp your hands together in front of your heart. Keep your gaze forward and take up to six easy breaths. Then repeat, this time standing on your right leg and lifting your left. If your balance is shaky, rest your hands on a chair in front of you.
