Positive thinking, meditation, or forest bathing: We do a lot to achieve that good feeling. In this book, you will learn everything about the chemicals and messengers that create the addictive sensation of happiness in our bodies. Loretta Breuning entertainingly and vividly explains how exactly dopamine, serotonin, endorphins, and oxytocin work, and how we can actively influence these biochemical processes.

With her guidance and practical exercises, happiness is guaranteed.
