Sleep disorders are the consequence of misalignments between the endogenous circadian clock and the external environment. Many of the mutations and polymorphisms associated with circadian rhythms ...

Circadian rhythms are the cycles that tell the body when to sleep, wake, and eat—the biological and psychological processes that oscillate in predictable patterns each day. This internal clock ...

Your circadian rhythm is your body’s internal clock. Light, sleep patterns, hormones, meals, and temperature can all influence your circadian rhythm, which in turn can influence your overall health.

The signals appear at appropriate times, thanks to the circadian clock. Using rhythmic environmental cues such as light, the circadian clock sets up a 24-hour internal oscillation that is replicated ...

The clock change affects our brains and circadian rhythms, leading to sleep disturbances and mood shifts. Neuroscientists weigh in on what can be done. 6 Ways to Improve Your Sleep Without Medication ...

“In a prior [human] study, we found that when behavior cycles of feeding and sleeping are not in normal alignment with the internal body clock, that this negatively affects the regulation of blood ...

Scientists map the circadian rhythm-regulating neurons and elucidate their roles in regulating behaviors in Drosophila The circadian clock, an internal timekeeping system, enables organisms to ...

The circadian clock plays a key role in coordinating many biological processes from behaviors to cellular metabolism and mitosis. Disruption of circadian rhythms can increase susceptibility to ...

“The circadian rhythm is generated by the master clock in the brain, an area of 50,000 cells near the hypothalamus [the hormonal control centre of the brain],” says Dr Kat Lederle, founder of ...
