Circadian

The term circadian rhythms refers to biological cycles that repeat about every twenty-four hours. ❋ M.D. Richard Ferber (2006)

So I think clearly what we call circadian rhythms, these oscillating clocks within the body, within cells in the body, clearly exist. ❋ Unknown (2006)

"Circadian rhythms are the outward manifestation of an internal timing system which is driven by several genetic elements, what we call circadian clock genes." ❋ Unknown (2010)

There is also the change in circadian rythmns, as I go from being a gainfully employed American to a retired one. ❋ Unknown (2005)

The word circadian is derived from the Latin circa diem or about a day and refers to the mysterious twenty-four-hour rhythms which control all brain outputs-behavioral, autonomic or neuro-endocrine-of all animals or humans who live on Earth with its twenty-four-hour alternation of light and darkness. ❋ Michener, James (1982)

Sleep patterns in children and adults follow what is known as the circadian rhythm, which determines how easily we fall asleep, stay asleep, wake up in the morning and maintain a level of alertness during the day. ❋ Unknown (2011)

Your body's clock, or body clock, is the time-keeping system inside you that controls your natural 24-hour sleep and wake cycle also known as your circadian rhythms. ❋ Hyungsoo Kim (2011)

It is called a circadian rhythm and if it is out of sync you get that feeling of being "so tired but I can't sleep" or you fall asleep at 6 p.m. on the couch, wake at 2 a.m. and wonder what happened. ❋ Unknown (2010)

Negative consequencesTeenager's biological rhythms - often referred to as their circadian rhythms - favor later bedtimes and later wake-up times. ❋ Unknown (2010)

The genes regulating this so-called circadian clock leave traces of their activity throughout the body. ❋ Unknown (2010)

How the weight gain occurs is that your body is regulated by biorhythms, also called circadian rhythms. ❋ Unknown (2009)

Jet lag comes courtesy of a disruption in your body's internal clocks, a condition known as circadian desynchronisation. ❋ Tusar N Mohapatra (2009)

This makes the sleep/wake cycle, also called the circadian rhythm, a good candidate for linking a person's social network to his or her cancer prognosis. ❋ GreenFertility (2008)

The round-the-clock society may not be everybody's ideal way to live, but for scientists it's a chance to challenge a natural limitation: what biologists call the circadian rhythm, a biological clock that locks every creature on the planet into a rhythm set by the rising and setting of the sun. ❋ Unknown (2007)

Your sleep/wake cycle is governed by an internal clock called the circadian (24-hour) rhythm. ❋ Unknown (2007)

These cycles are all controlled by the “biological clock,” also called the circadian, or central, pacemaker. ❋ M.D. Richard Ferber (2006)

A branch of science called circadian biology studies them in plants and animals, and discoveries in this field have been truly astounding. ❋ M.D. Richard Ferber (2006)

Guy #1: Dude, I swear that's [the 5th] time John accidentally hit on his sister while out [clubbing]. Guy #2: I think John's a prime example of [circadian fail]. ❋ Seargant007™ (2010)

John: Hey Steve, are you alright? You look like hell... Steve: Not really man, I was up all night studying for finals. I finally went to bed around 4:00 AM only to be awoken at [7:30] AM by an act of [circadian terrorism]. John: What do you mean? Steve: Well, my neighbor seems to enjoy hiring bands of workers to stand outside my bedroom window before [the crack of dawn] and hammer things. John: Wow, that fucking sucks. Steve: Yeah. ❋ Big Tall Giraffe (2010)

Person 1- "Where's [Cornelius] lately? I haven't seen him in months!" Person2- "Me neither. Since he started his new job he's had a full-on Circadian [Backflip]. He looks just like [Bela Lugosi] now!" ❋ JayszunVanderwerff (2011)

"We're out of condoms, but it's no problem... I've got enough [ambien] for us to use the circadian rhythm method." "Well, she's not on [THE pill], but she's on [A pill]... circadian rhythm method style." ❋ Maxkeepsitreal1 (2008)

"No, [I'll take] [my coffee] black, I really can't have milk [at this time] of the day. I just got diagnosed with C.L.I, better known as Circadian Lactose Intolerance. ❋ Jack Sparrow Wants This Woman (2009)
