The Chemistry of Joy presents Dr. Emmons's natural approach to depression -- supplemented with medication if necessary -- blending the best of Western science and Eastern philosophy to create your body's own biochemistry of joy. Integrating Western brain chemistry, natural and Ayurvedic medicine, Buddhist psychology, and his own joyful heart techniques, Dr. Emmons creates a practical program for each of the three types of depression: anxious depression, agitated depression, and sluggish depression. The Chemistry of Joy helps you to identify which type of depression you are experiencing and provides a specific diet and exercise plan to address it, as well as nutritional supplements and "psychology of mindfulness" exercises that can restore your body's natural balance and energy. This flexible approach creates newfound joy for those whose lives have been touched by depression -- and pathways for all who seek to actively improve their emotional lives.
