Early birds and night owls are born, not made. Sleep patterns are 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.

Quotes & Awards

  • Internal Time is a cautionary tale—actually a series of twenty-four 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.”

    Wall Street Journal

  • “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.”

    New Scientist

  • “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.”

    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.”

    New York

  • “A brilliant book.”


  • “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.”


  • “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

  • 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

  • “Not many recent titles cover this topic, and this is a welcome addition.”

    Library Journal

  • “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.”

    Wilson Quarterly
