I also enjoyed some of the descriptions of different sleep experiments. Once I did, I loved this book. Archived from the original on Roenneberg has also completed work on Neurospora crassadetermining the masking qualities of entrainment through a Frequency gene -null circadian oscillator.

These, imo, were the best part of the book. Additionally, individuals who are blind tend to have later chronotypes, because their eyes don’t get exposed to sunlight. The intrnal is sun time: As a late chronotype yime, 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.

It’s pleasantly written, although the German heritage of the author occasionally shows through his English. Roenneberg recommends that the best way to sync our internal time with our external environment and feel better is to get more sunlight. Each chapter begins with a fictional account that is intended to draw out the main premise of the chapter. To some extent, I still think it is.

Also, per the author, we should all get outside more into the natural light, eat better and add more motion to our lives. Not only does this impact on how we feel, but also how we digest, think and function. Yes, these steps can be taken — but they must be kept to every day. This chronotype questionnaire is important because it delves into the social aspects of circadian rhythms.


Contentious material about living persons that is unsourced or poorly sourced must be removed immediatelyespecially if potentially libelous or harmful. In addition, his work on dinoflagellates has been able to show that these two independent oscillators differ to a significant extent in that they respond differently when treated with various light pulses.

Social competence is reduced. Want to Read saving….

Internal Time: Chronotypes, Social Jet Lag, and Why You’re So Tired by Till Roenneberg

Teenagers are naturally later chronotypes. It’s not a self help book but just reading his research on sleep really helped me put my own situation roennebert perspective. The fictional chapter intros made me throw up a little in my mouth each time. He discusses how everyone is born with an internal clock, and living a lifestyle in dissonance with this inherent biological clock puts individuals at greater risk for health problems.

Jun 07, Lois Bujold rated it really liked it Recommends it for: And from personal experience, I would have to agree. Such simple steps as cycling to work and eating breakfast outside may be the tickets to a good night’s sleep, better overall health, and less grouchiness in the morning. Roenneberg recommends that the best way to sync our internal time with our external environment and feel better is to get more sunlight. 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.

As the Head of Human Chronobiology at the Institute of Medical Psychology at Ludwig-Maximilian University LMU of Munich, Roenneberg has unlocked the secret to how our unique internal clocks affect how and when we sleep — and why some of us are burdened with the disadvantage of living in a time zone which is not our own.


Surprised, he let the experiment run for a while. As a result, while I can’t recommend the book from the researcher angle, I can highly recommend the book from the subject angle.

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

What is social jet lag? Tell me more about this: With decreasing exposure to daylight from working inside and increased exposure to artificial light after sunset, we have drastically weakened the signals used by our clocks to synchronize to the hour day. By testing behavior rather than directly testing genetic factors, the MCTQ may offer new information regarding how the effects of external factors, including geographic location, seasons, obesity, social jet lag, or shift work, [11] may relate to genetic predispositions of circadian rhythms.

Instead, let me make a short comment about the presentation and leave it there. Late chronotypes tend to be able to stay up longer and “catch up” on sleep later easier than early chronotypes. Achteraf kan ik zeggen dat ik het niet langdradig vond, timd von Topboek!

The writing style is a bit like a textbook. The difference between the earliest and the latest ihternal in a population that works outside during the day and is exposed to darkness after sunset is about two hours. When hill came to the timing of leaf behavior, the plant, not the sun, was running the show. The anecdotes to start each chapter ranged from average to excruciating, and did little to move the book forward.
