Internal Time is an accessible, up-to-date overview of a subject that is important to all of us. With its remarkable depth and breadth of coverage, this book should be of interest to a wide and diverse audience. -- Martin Zatz, Editor, Journal of Biological Rhythms
This is a wonderful book from a gifted scientist, thinker and writer that provides the reader with the rare opportunity to discover something new about themselves and the world in which they live. -- Russell G. Foster, University of Oxford
In Internal Time, Till Roenneberg, a chronobiologist at the Ludwig-Maximilians University in Munich, Germany, takes readers on a journey through this mysterious area of science. He explores why some people are larks and others owls, why jet lag can be so debilitating to travelers, and why teenagers struggle to get out of bed in the morning...Roenneberg is a knowledgeable guide, with a talent for making difficult concepts clear and convincing...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 *
Time really is of the essence, says medical psychologist Till Roenneberg. By neglecting our body clocks--which rarely run in synchrony with the crazily cranked-up pace of modern life--we can develop social jetlag, endangering our health and careers. Roenneberg has built his book on decades of research in everything from fungi and single-celled organisms to humans. In brilliantly minimalist terms, he explains the temporal mismatches behind teen exhaustion, early birds and night owls, and sleep phobia. * Nature *
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 *
Till Roenneberg's book is an engaging and informative layman's introduction to circadian science and its implications for contemporary humans...By integrating quality scientific exposition with well-rounded human vignettes, Roenneberg's book shows how sophisticated human behaviors arise partly from our embodied earthly nature. -- Greg Murray * Times Higher Education *
Internal Time made me think deeply about what it means to be a time-bound organism: about the ways we live in time and the ways time lives in us. It is, in an unusually literal sense, a book about what makes us tick. -- Kathryn Schulz * New York *
A brilliant book. -- William Leith * Telegraph *
Fascinating...Other books have dealt with our biological clocks, but Roenneberg focuses on the ways in which societal pressures seem to be leading us to disregard our clocks, at considerable cost. -- Rob Dunn * Wilson Quarterly *
After reading this book, I've never more appreciated a good night's sleep...This is a fascinating, charming and eye-opening book about the sleepless menace lurking just below the surface of modern life. * Pumpjack Press *
