A groundbreaking international study, recently published in Health Data Science, analyzed objective sleep data from 88,461 adults in the UK Biobank and found significant associations between sleep traits and 172 diseases. The research, led by teams from Peking University and Army Medical University, highlights sleep regularity — such as bedtime consistency and circadian rhythm stability — as an underrecognized but …

Our usual understanding of sleep starts with the brain and ends with the mattress, yet new evidence points to a far smaller arena. Two hundredths of a millimeter below the surface of a nerve cell, the mitochondria may be counting the minutes we stay awake, then ordering the lights out. A team working with Drosophila melanogaster shows that the same …

But the search for such a pill—or indeed any treatment as effective as CPAP—has proved challenging. Dozens of drugs have failed to show efficacy in clinical trials, and while HGNS was first approved by the US Food and Drug Administration in 2014, Miller says that its rollout has been limited, as many doctors are uncertain about the risk-to-benefit trade-off. “The …

Recent reports that sleeping more than nine …

Then, around 13 to 17 years later, those same participants received brain scans to look at the size of specific regions known to be vulnerable in Alzheimer’s disease, like the inferior parietal lobule and precuneus. These areas are key players in memory, attention, and spatial reasoning—all functions that tend to decline early in dementia. Source link

If you use a third-party sleep tracker with your Apple Watch, you’re probably familiar with the concept of a sleep score: an index that combines signals like heart rate variation and sleep stages, to tell you how efficient your sleep really was. And while the Apple Watch gained native sleep tracking with watchOS 7, it’s been missing that kind of …

Earlier today we saw iOS 26 code suggesting that an Apple Watch sleep score feature is in development, with a percentage score indicating your readiness to tackle the day ahead. The feature also provides a more condensed graphical representation of your sleep stages than is currently available. What is shown and described looks like a very close match for two …
