Internal Time — Till Roenneberg | Harvard University Press

Comece a ler Internal Time no seu Kindle em menos de um minuto. Internal Time made me think deeply about what it means to be a time-bound organism: As for Daylight savings 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. 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.

Following the story, the science is explained in detail. I’ve been planning to read it for a long while now, but always had something else to read, so my anticipation grew larger and larger without realizing.

When I heard about this book, it seemed only logical that I would give it a try; after all, the question “Why am I always so tired” has surely passed all of our heads a few times in our lifetime. Seriously, it’s full of interesting stuff. Feb 24, Barb Wilson rated it it was ok. Jan 05, Jean rated it liked it Shelves: Didn’t love it; felt it was too heavy on statistics and boring explanations.


Adolescents have naturally later internal clocks, and in Germany many schools start before 8 a. Once I did, I loved this book.

We learn why the constant twilight of our largely indoor lives makes us dependent on alarm clocks and tired, and why social demands and work schedules lead to a social jet lag that compromises our daily functioning.

Our work times need to be much more flexible.

Unlocking the Science of Social Jet Lag and Sleep: An Interview With Till Roenneberg

Contentious material about living persons that is unsourced or poorly sourced must be removed immediatelyespecially if potentially libelous or harmful. In urban societies, this difference is almost twelve hours. Your cognitive performance is reduced greatly. In the spring your body is slowly attuning itself to earlier sunrise, so that you wake before the sun, then with the sun, then after the sun comes up.

This ability to torture ourselves on the wheel of time is also, he argues, one reason our species was so successful — we were able to occupy an evolutionary niche no other animal had success with: Instead, it is something deeply rooted at our cellular level.

But he didn’t give any help in how to adjust if you find yourself in a new time zone. Jun 17, Megan rated it it was ok.

The book was so fascinating, Roenneberv couldn’t put it down! While we have control over when we want to wake and sleep, at our core there is a mechanism that has preset when we should wake and sleep.


Till Roenneberg

Curious to test his hypothesis, he placed the mimosa in a dark cabinet, theorizing that the light-deprived leaves would stay closed. Unlike other chronotyping methods, which address the psychology of sleep, the MCTQ measures the phase angle of entrainment[9] the difference between an organism’s intrinsic circadian period and the environmental light cycle.

They are also more innovative. I enjoy learning about subjects I’m not -and probably never will be- an expert of. Masking has significant implications not only for future studies — which must attempt to demask affected data — but also in relation to entrainment in everyday life. Great article on the book: Additionally, individuals who are blind tend to have later chronotypes, because their eyes don’t get exposed to sunlight.

Still, great examples best in a scientific book I’ve read in a long time and a fascinating topic.

Can we take steps to avoid social jet lag, like increasing our exposure to light in the morning and decreasing our exposure to light in the evening? Covered are topics like why teenagers sleep all day, why people living in the country go to sleep earlier than their counterparts in cities, and why couples tend to have different bedtimes. Wat ik vooral interessant vond, was het hoofdstuk over het verplaatsen van mensen naar een andere planeet.
