Product details

Sleep is often an underestimated foundation of our well-being. In a time when constant connectivity, sensory overload, and stress shape our daily lives, our sleep often suffers. The consequences range from daytime fatigue and concentration problems to serious health impairments. Renowned sleep researchers and physicians Prof. Dr. med. J. Ulrich Sommer and Prof. Dr. med. Clemens Heiser demonstrate that sleep is one of the keys to a fulfilling and vital life. With their solid knowledge and the proven "Sleep Formula by Heiser & Sommer," they help people enjoy restful nights again – covering the fundamentals of sleep, the effects of technology, and effective methods for dealing with sleep issues.
