Even though disciplined sleeping habits and the adrenalin of live radio ensures that we are very awake while on duty, there is evidence of a phenomenon called circadian desynchronosis which causes one's brain to function slowly at those times of day when it thinks it should be asleep, regardless how wide awake the body is.

There is the idea that, when we look at things, it is the yellow light that helps us the most, that we are the most sensitive for. But our circadian rhythms, which are the rhythms that help us to wake and sleep and be alert and relaxed and so forth and so on, they are much more triggered by blue light.

The circadian neurons are one of the few circuits in neurobiology where we have a chance to understand at multiple levels how different sets of neurons communicate with each other - including understanding the wiring rules, the biochemical rules, and the functional behavioral rules.

I try to manage my day by my circadian rhythms because the creativity is such an elusive thing, and I could easily just stomp over it doing my administrative stuff.

Part of how easily we go to sleep is genetic: many sleep disturbances, ranging from insomnia to circadian disruption, have a large genetic component.

The same biological clock ticks away in humans and fruit flies, which underscores the importance of circadian timing to life on this planet.

Our circadian biology, and the insatiable early-morning demands of a post-industrial way of life, denies us the sleep we vitally need.

I'm envious of people who can sleep as long as they want. I have the circadian rhythm of a farmer.

Most important for the circadian field was the pioneering work of Ron Konopka in Seymour's lab.

The word 'circadian' goes beyond night-related patterns and includes all biological cycles repeated every 24 hours.

Not Just Night

'Circadian' is mainly used in scientific contexts to discuss biology, physiology, and behavior.

Scientific Context

'Circadian' often precedes 'rhythm' to specify the daily cycles of biological activities.

Daily Cycles

 These include smaller frontal lobes and hippocampal volumes. On a more microscale, depression is associated with a few the abnormal transmission or depletion of certain neurotransmitters, especially serotonin, norepinephrine, and dopamine, blunted circadian rhythms,

 In today's modern medicine, there is a real understanding of light in an almost biochemical way. And there is the idea that, when we look at things, it is the yellow light that helps us the most, that we are the most sensitive for. But our circadian rhythms,

 You might be wondering how normal light could possibly impact cancer rates. It likely all comes down to the super important hormone called melatonin, which we have evolved over millions of years to produce on a day-night cycle, or a circadian rhythm.

 That's because of circadian rhythms, the internal timekeepers that tick away inside many living things. These biological clocks allow organisms to keep track of time and pick up on environmental cues that help them adapt.

 Despite having no external cues, he fell asleep, woke up, and ate at fixed intervals. This became known as a circadian rhythm from the Latin for "about a day."
