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

My sleep deprivation was affecting every aspect of my life. I read several books on sleep training, as well as blogs and websites. I was at my wits end. After following the program for two weeks, my child was consistently sleeping 11-12 hours a night and was on a consistent schedule during the day! This program has literally given me my life back." - McKel Neilsen "Two months ago I was at the end of my sleep rope with our 6-month-old, boy/girl twins. Exhausted doesn't begin to explain it, I felt desperate. After using the Baby Sleep Trainer Method we feel like we have our lives back. The babies are happy and well rested, and so are we! We have our evenings back to cook dinner, spend time with our 4-year-old daughter, hang out together, and actually do things we enjoy. The process took commitment but has been absolutely worth every bit of it." - Beth Oller, MD "Using the Baby Sleep Trainer Method, my daughter quickly went to a routine nap schedule during the day and sleeping through the night from 6:30pm to 6:30am! Also, rather than the exhausting and often unsuccessful rocking or soothing or feeding to sleep, we were able to put her down awake in her crib and she would fall asleep on her own in just a few minutes. It was just incredible." - Online Review
