Sleep

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.

Scientists in China have developed a smart pillow designed to offer an accessible and accurate sleep-tracking solution, monitoring the quality of rest through head movements, which work to power the system at the same time.

Scientists are beginning to explore the relationship between climate change and sleep quality, based on the premise that rising ambient temperatures are impacting our rest. And a new study indicates it may already be costing us many hours per year.

A wide-ranging new study involving almost half a million subjects has provided compelling new insights into what constitutes healthy sleeping habits, suggesting seven hours per night is best for brain health during middle and old age.

As we get older, it becomes more difficult not just to get to sleep, but also to reach and maintain a state of deep sleep. The experimental new SleepLoop device is designed to help, by emitting noises into the wearer's head.
