We all want to feel good. In recent years, ideas about wellness ("wellness," "well-being," which includes both physical and mental health) have become widespread in popular culture. But is this concept backed by science? What do we really know about happiness, pleasure and wellbeing in the brain? In this fascinating, fun and rewarding book, Cambridge University neuroscientist Camilla Nord takes the reader up-to-date on the neuroscience of wellness - from "pleasure hotspots" in the brain to gut-brain connectivity and the effects on the brain of electrical stimulation and drugs. Drawing on her own scientific research and recent tests, she shows that some widespread beliefs are nothing more than myths, while others are absolute truths. It provides tools for those who want to better understand their minds and thereby become happy. Dr. Nord shows that every brain is different and that there is no one-size-fits-all approach to wellness. Ultimately, she argues, it's crucial to find what helps us experience guilt-free pleasure - whether that's meditation, exercise or chocolate.
