La química de la felicidad

We all have chemical substances inside us that can radically transform our mood when activated. With the help of this book, you'll learn to stimulate your four happiness hormones whenever you need a little boost. First, identify which one you think you need most: - Serotonin: the mood regulator. - Oxytocin: the love hormone. - Dopamine: the reward complex. - Endorphins: the body's natural pain reliever. Then, simply go to the corresponding page, follow the instructions, and let your body do the rest. Read one page a day...and happiness will come on its own.
