Systems and methods for monitoring sleep are disclosed. According to an aspect, a method includes emitting light into tissue. The method also includes detecting light backscattered from the tissue. Further, the method includes determining a sleep pattern based on the backscattered light.Alper Bozkurt...
(生理节奏)can become compromised quite easily.Many people with sleep troubles tend to vary bedtimes.To avoid this common problem,sleep sufferers should go to bed and wake up at the same time every day.To help improve circadian rhythms,sufferers should enjoy 15 minutes of sun exposure the ...

What comprises adequate sleep, however, varies in relation to inter- and intra-individual differences. With respect to age, the ...
Circadian rhythms affect yoursleeppatterns as well as other ways your body works, like your hormones, body temperature, and eating habits. When they get out of sync, they might also cause problems with your health. They’ve been linked to different disorders includingdiabetes,obesity, anddepressio...
When mammals are exposed to light, the retina is activated and transmits information to the SCN. The SCN receives, converts, and integrates the information from the external environment to tissues, which synchronizes the signals to regulate its own rhythms and peripheral rhythms and maintain ...
A series of findings over the past decade has begun to identify the brain circuitry and neurotransmitters that regulate our daily cycles of sleep and wakefulness. The latter depends on a network of cell groups that activate the thalamus and the cerebral
New research from a multidisciplinary team is helping to shed light on the mechanisms behindcircadian rhythmsand offer new hope for dealing withjet lag, insomnia and other sleep disorders. Using innovative cryo-electron microscopy techniques, researchers have identified the structu...
Circadian regulation is the control of the cyclic variation of physiological processes over a 24 hour cycle. The suprachiasmatic nucleus (SCN) in the brain is understood to be the 'master regulator' or 'central pacemaker' of circadian rhythms, and circadian oscillations of so called 'clock genes...
Of course, there’s still a lot of work to be done. While we know that circadian misalignment is a risk factor for disease, we don’t yet know how much misalignment is bad for you. TimeSignature enables further research to quantify the precise relationships between circadian rhythms and dise...
It's because you—and most other animals—have a kind of internal clock that controls the cycle of the day's biological activities, such as sleeping and waking. These daily biological activities are known ascircadian rhythmsbecause they are influenced by the regular intervals of light and dark ...
