A GUIDE TO USING THE SCIENCE OF THE BODY CLOCK TO CREATE THE OPTIMUM PERSONAL ROUTINE. SLEEP BETTER, WORK BETTER, FEEL BETTER.'A superlative guide to some of the most intriguing questions of human existence' Bill BrysonIn the twenty-first century, we increasingly push our daily routines into the night, carrying out work, exercise and our social lives long after dark. But we have forgotten that our bodies are governed by a 24-hour biological clock which guides us towards the best time to sleep, eat and think. New science has proven that living out of sync with this clock is not only disrupting our sleep, but leaving us more vulnerable to infection, cancer, obesity, type 2 diabetes, heart disease and mental illness.In Life Time, Professor Russell Foster shares his life's work, taking us on a fascinating and surprising journey through the science of our body clocks. Using his own studies, as well as insights from an international community of sleep scientists and biologists studying circadian rhythms, he illustrates the surprising effects the time of day can have on our health:- how a walk outside at dawn can ensure a better night's sleep- how eating after sundown can affect our weight- the extraordinary effects the time we take our medication can have on our risk of life-threatening conditions, such as strokesIn the modern world, we have neglected an essential part of our biology. But with knowledge of this astonishing science, we can get back into the rhythm, and live healthier, sharper lives.

An eye-opening discussion of how biological clocks affect the lives of all living organisms Why can't teenagers get out of bed in the morning? How do bees tell the time? Why do some plants open and close their flowers at the same time each day? Why do so many people suffer the misery of jet lag? In this fascinating book, Russell Foster and Leon Kreitzman explain the significance of the biological clock, showing how it has played an essential role in evolution and why it continues to play a vitally important role in all living organisms. The authors tell us that biological clocks are embedded in our genes and reset at sunrise and sunset each day to link astronomical time with an organism's internal time. They discuss how scientists are working out the clockwork mechanisms and what governs them, and they describe how organisms measure different intervals of time, how they are adapted to various cycles, and how light coordinates the time within to the external world. They review problems that can be caused by malfunctioning biological clocks--including jet lag, seasonal affective disorder, and depression. And they warn that although new drugs are being promoted to allow us to stay awake for longer periods, a 24/7 lifestyle can have a harmful impact on our health, both as individuals and as a society.
