Proč mozek potřebuje přátele - Mezilidské vztahy pohledem neurovědy – Rein Ben (2026)

Whether you are an introvert or an extrovert, your brain needs other people. What do a morning conversation with a barista while ordering coffee, laughing with colleagues after work and talking on the sofa in the evening have in common? They are all moments that literally nourish the human brain. This is not a metaphor but a scientific fact. Every social interaction leaves a biological trace in the brain that affects health, mood and even life expectancy. In this Czech-language book, Dr Ben Rein, one of the leading American neuroscientists, opens your eyes to a subject we overlook every day: the human brain is fundamentally made for connection with other people. The modern world, with its screens, isolation and rushed pace, is gradually and unobtrusively depriving us of that connection. It takes away not only our good mood but also our health in the deepest sense. Loneliness is not merely an unpleasant feeling; it poses a serious health risk. This book is not intended to frighten you, but to offer hope and inspire change. Dr Rein combines the latest scientific findings with engaging stories and clear advice that you can start using immediately. You will learn why and how even very brief social interactions affect brain health, what happens in the body during prolonged isolation and why it is dangerous, why a video call is not the same to the brain as meeting in person, how first impressions work and what makes someone immediately likeable, how empathy functions at the cellular level and why it matters, why having a pet is beneficial to your health, how different substances, from caffeine to medicines, alter the way we relate to one another, and how to consciously create a “social diet” that nourishes both body and mind.
