The definitive guide to the therapeutic Japanese practice of shinrin-yoku, or the art and science of how trees can promote health and happiness. Notice how a tree sways in the wind. Run your hands over its bark. Take in its citrusy scent.

In this beautiful book—featuring more than 100 color photographs from forests around the world, including the forest therapy trails that criss-cross Japan—Dr. Qing Li, the world's foremost expert in forest medicine, shows how forest bathing can reduce your stress levels and blood pressure, strengthen your immune and cardiovascular systems, boost your energy, mood, creativity, and concentration, and even help you lose weight and live longer. Once you've discovered the healing power of trees, you can lose yourself in the beauty of your surroundings, leave everyday stress behind, and reach a place of greater calm and wellness.
