New research has now zeroed in on the finer details of how weight gain and obesity can be a driver of sleep apnea, revealing that a reduction of fat in the tongue appears key to lessening the severity of its symptoms.

A new study from the University of Manchester is questioning common consensus, arguing perceived color can influence circadian clocks. Animal experiments suggest exposure to yellow light at night from screens could be confusing our body clocks.

A new study suggests sleeping more than nine hours a night, and/or taking long midday naps, can significantly increase a person’s risk of stroke. The research adds to a growing body of work finding deleterious health effects from excessive sleep.

Scientists at UC Berkeley have homed in on exactly which phase of sleep seems to best keep anxiety levels in check. The research suggests sleep deprivation lowers activity in the prefrontal cortex, a brain region that helps regulate our emotions.

Babies certainly like being rocked to sleep, and really, so do adults – the problem is, adult-sized beds don't rock. The Ensven system is designed to remedy that situation, bringing movement to your boring old bed.

An intriguing new study is offering insights into the origins of sleep, for the first time discovering zebrafish brains shift through several brain states while sleeping, which researchers suggest could be analogous to human slow-wave, and REM sleep.

New research has found a strong association between irregular sleep patterns and an increased risk of metabolic disorders such as hypertension, obesity and diabetes. The study suggests there is a possible causal connection between inconsistent sleep schedules and metabolic dysfunction.
