Quotes About Circadian

People born in the fall and winter are more likely to be larks;

The problem is that our corporate, government, and education cultures are configured for the 75 or 80 percent of people who are larks or third birds. Owls are like left-handers in a right-handed world—forced to use scissors and writing desks and catcher's mitts designed for others. How they respond is the final piece of the puzzle in divining the rhythms of the day.

Each of us has a "chronotype"—a personal pattern of circadian rhythms that influences our physiology and psychology.

Even "sophisticated economic agents acting in real and highly incentivized settings are influenced by diurnal rhythms in the performance of their professional duties.

What time do you usually go to sleep? What time do you usually wake up? What is the middle of those two times—that is, what is your midpoint of sleep?

all of us experience the day in three stages—a peak, a trough, and a rebound. And about three-quarters of us (larks and third birds) experience it in that order. But about one in four people, those whose genes or age make them night owls, experience the day in something closer to the reverse order—recovery, trough, peak.

Internal Time: Chronotypes, Social Jet Lag, and Why You're So Tired (2012) By Till Roenneberg If you're going to read one book about chronobiology, make it this one. You'll learn more from this smart, concise work—organized into twenty-four chapters to represent the twenty-four hours of the day—than from any other single source.

All living things respond to the same 24-hour rhythm, in tandem with the Earth's rotation. Halberg coined the terms "chronobiology"—the influence of time and certain periodic cycles on biological function—and "circadian" (from Latin circa = about; and dies = day) for daily biological rhythms.

Peak performance in most sports occurs in late afternoon and early evening, when body temperature reaches its daily high. Respect for this body rhythm may decrease your likelihood of injuries,

The circadian timing system modulates the activity of every cell in our body. Timed light exposure is nature's way of keeping the activity of these cells in check.

We are confronting three main factors that can underlie depression: an internal clock that runs slower than 24 hours, late evening light exposure that adds physiological time and further slows the process, and a dark bedroom that disallows the morning light signal essential for achieving synchrony with local solar time.
