Our body's clocks make the difference between happiness and depression, health and illness, and even life and death. The brilliant scientist Paul Kelley makes a compelling case for all organisations to allow people to work and study the hours that suit their personal circadian rhythms. That way, Paul argues, we would all be more productive, a great deal of ill health would be avoided and the world would be a better and happier place.

A fascinating journey through our circadian rhythms, sleep, and health, by a world-leading expert on circadian neuroscience “Full of surprising and useful facts. . . . Unlike many science books with similar subtitles, it really might ‘revolutionise’ your life.”—James McConnachie, The Times (London) “Life Time should certainly be mandatory reading for night-shift workers, but its messages are so universal that it would be hard not to gain some sleep smarts from its pages, whoever you are.”—Alex Wilkins, New Scientist The routines of our modern lives—home working, night shifts, technology—are playing havoc with our body clocks, sleep patterns, and health. Packed with cutting edge science, this book by award-winning scientist Russell Foster takes the reader on a journey through our days and nights, and explains how we can get back into rhythm and live healthier, sharper lives. In the past few decades, there has been an explosion of discoveries around the science of the body clock and our twenty-four-hour biological cycles. Sleep and daily rhythms emerge from our genetics, physiology, behavior, and the environment. Like most of our behaviors, they are not fixed. These rhythms are modified by our actions, how we interact with the environment, and how we progress from birth to old age. Cutting through long-standing myths, Foster empowers readers by providing concrete information and guidance that can be used to understand what makes the body clock “tick.&rdquo

We all know how tough it is for a night owl to get going at 7.00 A.M., and it's equally challenging for a morning person to stay awake late at night...Dr. Edlund's professional research has led him to identify body rhythms and how they affect our lives. Once we have determined our own body clock we can stop fighting our natural preferences and allow our lives to flow more productively, and with more positive results.

Why am I always tired? Why can't I sleep at night? Why do I suffer from jetlag? We all have a body clock, a biological structure that controls how we feel, our mental and physical performance, and whether we are active or asleep. This is nature's response to our rhythmic environment, dominated by day and night. Though the body clock normally adjusts us to daytime activity andnight time sleep, it can go wrong or be tricked by lifestyle changes. This can result in jetlag, some forms of insomnia and even depression. Keeping in time with your body clock provides clear and accessible advice on how to live with, and not against, your body clock. In a clear and accessible style, it explains how the body clock works, how and why it can work against you, and the measures you can take to optimise your feeling ofhealth and wellbeing. It also explains the role of the body clock in illness, and how an understanding of this can increase your feeling of health. An essential book for anyone who wants to better understand their body and optimise their feeling of health and wellbeing.

Winner of a British Medical Association Book Award A Brain Pickings Best Science Book of the Year Early birds and night owls are born, not made. Sleep patterns may be the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. Living at odds with our internal timepieces, Till Roenneberg shows, can make us chronically sleep deprived and more likely to smoke, gain weight, feel depressed, fall ill, and fail geometry. By understanding and respecting our internal time, we can live better. “Internal Time is a cautionary tale—actually a series of 24 tales, not coincidentally. Roenneberg ranges widely from the inner workings of biological rhythms to their social implications, illuminating each scientific tutorial with an anecdote inspired by clinical research...Written with grace and good humor, Internal Time is a serious work of science incorporating the latest research in chronobiology...[A] compelling volume.” —A. Roger Ekirch, Wall Street Journal “This is a fascinating introduction to an important topic, which will appeal to anyone who wishes to delve deep into the world of chronobiology, or simply wonders why they struggle to get a good night’s sleep.” —Richard Wiseman, New Scientist

"Reset Your Inner Clock reveals a powerful program that recalibrates our internal clocks that can be decimated by the modern demands of a 24/7 lifestyle"--

A medical breakthrough explained by the leading authority on the connection between health and your body clock Chronotherapy-adjusting the care of the body to coincide with the body's natural clock-is poised to be the next major revolution in medical science. An understanding and awareness of these rhythms will enable us to maximize the effects not only of medications and other treatments, but also of diets, exercise programs, and other daily routines. The Body Clock Guide to Better Health combines a detailed discussion of major issues such as sleep, exercise, and nutrition, with a comprehensive A-to-Z reference to specific disorders. Among the health concerns it addresses are AIDS, arthritis, asthma, ADD, backache, cancer, depression, diabetes, digestive problems, allergies, heart disease, chronic pain, sexual dysfunction, stroke, and complications from pregnancy. General chapters explore the big picture-including monthly cycles and life cycles-and provide invaluable advice on foods and dietary supplements, fitness, better sex, jet lag, and more. The first book to look at body rhythms from a practical perspective, The Body Clock Guide to Better Health offers readers the dual benefits of improving the treatment of specific conditions while boosting their overall health and wellness.
