Synopses & Reviews
Why cant 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 organisms 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 clocksincluding 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.
"In their wonderful book, Russell G. Foster and Leon Kreitzman tell us that while our ability to measure time has improved over the ages, we have nevertheless 'been steadily losing a battle with time. Instead of controlling our modern clocks, they control us.'" Oren Harman, The New Republic
