During the pandemic, the amount of screen time for many people working and learning from home as well as binge-watching TV has sharply increased. New research finds that wearing blue-light glasses just before sleeping can lead to a better night's sleep and contribute to a better day's work to follow.
International researchers publishing in Science Advances reveal in a mouse study that chronic jet lag alters the microenvironment surrounding tumor cells, making it more favorable for tumor growth, and also hinders the body's natural immune defenses.
The time of day when we exercise could affect the risk of cancer due to circadian disruption, according to a new study with about 3,000 Spanish people
Biological clocks have sizeable effects on the performance of elite athletes. This conclusion was drawn by chronobiologists from the University of Groningen after studying the times achieved by swimmers in four different Olympic Games. Shifting the clock to reach peak performance at the right time could make the difference between winning and losing. The results were published on 8 October in the journal Scientific Reports.
A new study published today in the journal Current Biology suggests that star-shaped brain cells known as astrocytes could be as important to the regulation of sleep as neurons. The study builds new momentum toward ultimately solving the mystery of why we sleep and how sleep works in the brain. The discovery may also set the stage for potential future treatment strategies for sleep disorders and neurological diseases and other conditions associated with troubled sleep.
Obstructive sleep apnea (OSA) affects more than one billion people worldwide. Evidence suggests OSA can alter the gut microbiome (GM) and may promote OSA-associated co-morbidities, including diabetes, hypertension and cognitive problems. Researchers from the University of Missouri School of Medicine have discovered how OSA-related sleep disturbances affect the gut microbiome in mice and how transplanting those gut bacteria into other mice can cause changes to sleep patterns in the recipient mice.
Early to bed, early to rise...while the old saying promises health, wealth and wisdom, new research confirms part of the adage holds true, as a world first study shows that people who go to bed early are more likely to be in better health and more physically active compared to night owls.
UCLA researchers have pinpointed a second hand to the brain's internal clock. By revealing how and where the brain counts and represents seconds, the UCLA discovery will expand scientists' understanding of normal and abnormal brain function.
For the first time, scientists have studied the early effects of time-restricted feeding on the daily periodic oscillations of metabolites and genes in muscle, and metabolites in blood. The findings by scientists at the University of Copenhagen, the Australian Catholic University and Karolinska Institutet find that time-restricted feeding does not influence the muscle's core clock, and opens the door to more research on how these observed changes improve health.
Research from the University of Kent has found that TRESK, a calcium regulated two-pore potassium channel, regulates the brain's central circadian clock to differentiate behaviour between day and night.
