Pull

Gravity doesn’t just pull apples from trees — it shapes our bodies, minds, and even our emotions. Dr Brennan Spiegel reveals how this invisible force influences everything from digestion to depression — and how building gravity resilience can help us find balance, stand stronger, and live longer.

Pull presents a groundbreaking exploration of how gravity influences conditions of body and mind that have puzzled medical professionals for centuries. Why do people with depression literally feel like they’re being dragged to the ground? Why do you get that butterfly feeling in your stomach when going down a roller coaster? Why do you get it when you are ‘falling’ in love? What can we learn from astronauts with heartburn and swollen faces to inform our lives back on Earth? How do gut microbes help us fight gravity? And most importantly, how can we change our connection to gravity for the better? To get there, Spiegel proposes the concept of ‘gravity resilience’, a fresh perspective on traditional interventions such as weight loss, exercise, diet, and meditation.

Rooted in hard science, buttressed by compelling storytelling, and punctuated with actionable strategies to boost your own gravity resilience, Pull is an eye-opening, life-changing book.
