Research shows that neurons in the brain are rhythmically activated during non rapid eye movement sleep. Stress activates the brain cells, and interrupts sleep cycles. Suppressing these neurons may be a target to treat stress related sleep disorders

The study, published today in Sleep Health, is one of the first to measure multiple environmental variables in the bedroom and analyze their associations with sleep efficiency—the time spent sleeping relative to the time available for sleep.

Can staying up late make you fat? A growing body of research has suggested that poor sleep quality is linked to an increased risk of obesity by deregulating appetite, which in turn leads to more calorie consumption.

An important biological mechanism that is thought to protect brain cells from neurodegenerative diseases such as Alzheimer’s and Parkinson’s may also be involved in regulating sleep, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Losing weight is an effective treatment for Obstructive Sleep Apnea (OSA), but why exactly this is the case has remained unclear.

While it’s reported that chronic disruptions of circadian rhythms, or internal body clocks, can lead to an increased risk of cancer, the underlying mechanisms by which the disturbances promote tumor growth had been largely unknown.

About 25 percent of Americans experience acute insomnia each year, but about 75 percent of these individuals recover without developing persistent poor sleep or chronic insomnia, according to a study from researchers at the Perelman School of Medicine at the University of Pennsylvania which will be presented Monday at SLEEP 2018, the 32nd Annual Meeting of the Associated Professional Sleep Societies LLC (APSS).

The key to predicting how someone is affected by sleep loss may be found in microRNAs (miRNAs), according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.
