Internal Time by Till Roenneberg

Internal Time

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 un...

  • Lois Bujold
    I could hardly write a better review than this one, which sent me to Amazon Kindle to buy a copy: chapters of the latest news from sleep studies. Good and useful information for Owls like me, and the Larks who have to live/deal with them.The one item I was hoping for, and did not find in the read, was anything on studies of sleep disruption in women enduring menopause. It seems to me this would be a perfe...

    The question "Why I am I so tired" was a major one for me at the time of reading this book. It's not a self help book but just reading his research on sleep really helped me put my own situation in perspective. As a late chronotype myself, I particularly enjoyed how he defended us, by demonstrating that the old adage "the early bird gets the worm" might well have applied to a traditional agrarian community but it is not necessarily true for moder...

    Great article on the book:*****By the way, this is another "heavy on the details" style review. If you just want the thumbs up/ thumbs down on content, writing style, and scientific accessibility, scroll to the end of the review.*****This is the book for all you night owls that are always fighting the "early to bed, early to rise" philosophy. 1) "Early to bed, early to rise" is a remnant of agrarian societ...

    I became familiar with Roenneberg's work while taking a chronobiology course that mentioned him and the subject matter in this book. The writing style is a bit like a textbook. I listened to an audio version of this book and found myself zoning out. About a 1/4 through the book, I had to start over and make myself pay attention. Once I did, I loved this book. While taking chronobiology, I learned about the various chronotypes in humans and how th...

    Are you a lark, or an owl? Do you bound out of bed 15 minutes before your alarm sounds, or are you continually hitting the snooze button ‘just one last time’? The culprit is your internal clock, a biological device found even in creatures as lowly as bread mould, which is used to synchronise our waking activities to the sun.Roenneberg argues that your ‘chronotype’* – whether you are an early bird or a night owl – can impact several th...

    Fascinating new information such as that some people make their melatonin in the day time and so should sleep in the day time which is NOT accepted by our society overall. Larks think everyone should be larks. Owls are more extroverted which sure surprised me. They are also more innovative. Children born with Smith-Magenis syndrome are very crabby from being expected to be awake during the day when they are producing melatonin. They can be helpe...

    Upside: This book confirmed my hatred of mornings is genetic and therefore really not my fault. Downside: I will peel myself off the mattress until I die.

    This was an accessible book for the non-scientist. A well-written description of internal time, that internal sense we all have that controls the rhythm of our daily lives. Where does it come from? How does it manifest? Can it be affected by other rhythms, environmental, social, or artificial? The author is an experienced chrono-researcher and was able to clearly describe a lot of the recent research that has illuminated our understanding of chro...

    The subject was interesting, and there was some good information here, but the book as a whole I didn't enjoy. The anecdotes to start each chapter ranged from average to excruciating, and did little to move the book forward. Glad to be done with this.
