This book is based on research findings that led to the discovery of ultradian rhythms. At certain intervals, our body gives us important signals to indicate that we should take a break. However, we often overlook even clear signs such as yawning, daydreaming, decreased concentration, forgetfulness, hunger, and emotional instability, and instead try to combat fatigue with caffeine, sweets, nicotine, alcohol, or other drugs. If we continuously ignore our need for recovery, we soon feel stressed and exhausted, developing a variety of psychosomatic illnesses. Ernest Rossi shows us in this book how we can prevent such a mental and physical breakdown by learning to recognize our body's signals and making it a habit to take breaks at home or at work.
