Brian Johnson reviews Kate Hefferon’s Positive Psychology and the Body, arguing that positive psychology must incorporate the body (movement, nutrition, nervous system) to fully support flourishing. He outlines definitions and history (Seligman, PERMA, Aristotle), explains autonomic nervous system balance and HRV, presents longevity evidence (notably a nun study linking positive affect to survival), and highlights risks of ungrounded positivity. Practical recommendations include reducing sugar and ultra‑processed foods, increasing physical activity (exercise comparable to antidepressants in some studies), improving sleep hygiene (reduce nighttime blue light), and tracking recovery metrics. Johnson also mentions Optimize program results showing large self-reported gains in connection to one’s ‘‘best self.’’
