Body clocks of depressed people altered at cell level, researchers show
Every cell in our bodies runs on a 24-hour clock, tuned to the night-day, light-dark cycles that have ruled us since the dawn of humanity. The brain acts as timekeeper, keeping the cellular clock in sync ...

Monday's medical myth: You need eight hours of continuous sleep each night
We're often told by the popular press and well-meaning family and friends that, for good health, we should fall asleep quickly and sleep solidly for about eight hours—otherwise we're at risk of physical ...

Disruption of biological clocks causes neurodegeneration, early death
New research at Oregon State University provides evidence for the first time that disruption of circadian rhythms – the biological "clocks" found in many animals – can clearly cause accelerated neurodegeneration, ...

Study shows new evidence of age-related decline in the brain's master circadian clock
(Medical Xpress) -- A new study of the brain's master circadian clock — known as the suprachiasmatic nucleus, or SCN — reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The ...

Researchers discover molecular link between circadian clock disturbances and inflammatory diseases
Scientists have known for some time that throwing off the body's circadian rhythm can negatively affect body chemistry. In fact, workers whose sleep-wake cycles are disrupted by night shifts are more susceptible to chronic ...

Circadian rhythm
A circadian rhythm is a roughly-24-hour cycle in the biochemical, physiological or behavioral processes of living entities, including plants, animals, fungi and cyanobacteria (see bacterial circadian rhythms). The term "circadian", coined by Franz Halberg, comes from the Latin circa, "around," and diem or dies, "day", meaning literally "approximately one day." The formal study of biological temporal rhythms such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology.
Circadian rhythms are endogenously generated, and can be entrained by external cues, called Zeitgebers, the primary one of which is daylight. These rhythms allow organisms to anticipate and prepare for precise and regular environmental changes.
