Sleep

A preliminary human study has shown promising results from an experimental nasal spray developed to treat sleep apnea. The early findings suggest a quick nasal spray before sleep could effectively keep a person's airways open throughout the night.

Researchers have demonstrated that inducing a kind of hibernation state could help protect organs from damage when blood circulation is stopped during surgery. The technique slows down the metabolism and has been found to work well in tests in mice.

New research in Nature Communications has strengthened the link between sleep apnea and dementia, by using preclinical models to demonstrate exactly how breathing disruptions during sleep can cause brain changes associated with Alzheimer's disease.

Waking up to a blaring alarm clock can be quite jarring, and also irksome if you're not even the person for whom the alarm was set. That's where SilentWakeUp comes in, as it wakes its wearer – and only its wearer – by silently buzzing their body.

A new study has highlighted one way insufficient sleep can harm your immune system, making you more vulnerable to infections and inflammatory disease by damaging your body’s hematopoietic stem cells.

We’re all maybe a bit surly after a sleepless night, but a new study suggests our levels of day-to-day selfishness can be directly related to how well rested we are, and these findings could have implications on both individual and societal levels.

A compelling study indicates Parkinson’s disease could be diagnosed by remotely tracking a person’s breathing patterns. Led by researchers from MIT, the study presents an AI system that uses radio waves to monitor breathing while a person sleeps.

A new study on fruit flies may help explain why siestas came to be such an important habit in many cultures, revealing a type of brain thermometer that kicks sleep-promoting cells into action as the mercury starts to climb.

Scientists have designed a smart mattress designed to tap into the body's circadian rhythms, carefully heating and cooling different areas to coax you into a deep slumber, with some promising results from an early trial.

A study has reviewed more than 150 clinical trials to present a comparative analysis of 30 drug treatments for insomnia. The findings indicate many lack long-term safety data and treatments such as melatonin have little evidence of effectiveness.

A new study suggests brain inflammation is the key factor linking sleep disturbances with Alzheimer’s disease. It's hypothesized the same overactive immune cells in the brain that contribute to cognitive decline can disrupt certain sleep cycles.

Scientists probing the mysterious machinations of the brain during sleep have made a fascinating discovery around how its chemistry changes throughout the night, which may have implications for the way we retain memories.
