Healthy eating and exercise make you leaner and more resilient, but your body also needs proper sleep to lock in the positive effects. After all, sleep affects weight, mental well-being, and reduces the risk of diseases—from the common cold to cancer. But the modern world challenges us with constant work stress, a sedentary lifestyle, and nonstop screen time on computers or smartphones. Professor Christian Benedict from Sweden’s oldest university, Uppsala, and a specialist in sleep neurobiology, in conversation with journalist Mina Tunberg, talks enthusiastically and knowledgeably about how insomnia increases unhealthy appetite, how amazing dreams help improve understanding of one’s own feelings, and how deep sleep phases strengthen immunity and neural connections in the brain. And this is only part of his discoveries! In this book, scientific facts alternate with practical advice that will help you understand what sleep is and make it deeper—so you can become happier and more energetic. © Storyside
