Internal Time: Chronotypes, Social Jet Lag, and Why You're So Tired
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 likel...more

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 things in your daily life. Covered are topics like why teenagers...more

A scholarly discussion of the study of the human body's internal clock, and the significant aspects of the field of sleep research. Although Roenneberg clearly strives to make his points accessible by including an illustrative story (in conversational tone) at the onset of each chapter, the concepts can get a bit heady. He divides the book into 12 chapters of two parts each, to mimic the night/day rhythms of our lives and our planet, and fitting as this is to the theme of the book, it seals it a...more
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 modern city dwellers.

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.

Lost a star for not discussing jetlag in sufficient detail for us in this modern jetsetting world. However a nice little easily-digested overview of this interesting niche of biological sciences. A good aeroplane read.
Very interesting subject matter, really irritating and cheesy "stories", veers wildly into heavy statistics stuff on occasion. I still enjoyed it and now think a lot about chronotypes!
I was a little disappointed with this book in that it had such potential. I would have liked more suggestions on how to properly use this knowledge of our body clocks.
Interesting none the less on why we sleep the way we do.

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.

I just wish this book had a last page of "sleeping best practices." Lots of good information here.

This was an interesting read - looking at the science behind the body's internal clock and our different chronotypes.

Found via Brain Pickings.
Perfect book (a little heavy on science) for those of us owls living in a lark's world. I'd love to see a follow-up with more actionable advice.
KIND OF A SNOOZE. SCHULZ'S REVIEW WAS A BETTER READ.
I *wanted* to like this book, but I felt I got more out the NY Times (I think) article where I heard about this book in the first place. I can't help but wish that Mary Roach had written about sleep...because at least I wouldn't have felt like sleeping while reading this book. Ha...ha? Get it? Anyway. Didn't love it; felt it was too heavy on statistics and boring explanations. Shame.
lark or owl?
