Clocks change this weekend, mice shed light on sleep in Alzheimer's, a European sleep paper calls for wider action, and Oura adds training tools. Here is your quick tour.
The clocks go back this Sunday
At 2am on Sunday 25 October, UK clocks go back one hour and we return to Greenwich Mean Time. The usual advice from a university guide is to keep a consistent sleep schedule, get outside in daylight and enjoy the extra hour as a slower morning.
Why it matters: an extra hour sounds lovely, but body clocks can take a few days to catch up, so steady bedtimes and morning light are your friends. Our guide to your body clock explains why.
Mice with Alzheimer's-like changes got their sleep back
University of Kentucky researchers found that overactive immune cells in the brain, called microglia, seem to play a part in lost sleep in mouse models of Alzheimer's. When most of these cells were temporarily removed with a drug, the mice slept more than two hours longer each day, even though their brain plaques did not change.
Why it matters: this is early animal research, and the authors note the same benefit has not been shown in people. It is an interesting clue that sleep trouble in dementia may have its own causes, not just a by-product of plaques.
Researchers say better sleep needs more than personal willpower
A new paper in the Journal of Sleep Research argues that hotter nights, round-the-clock technology, shift work and long hours are making sleep harder across Europe. The authors say individual tips are not enough and call on governments and employers to protect rest, while warning that wearables are not accurate enough for diagnosis and that obsessing over perfect sleep data can backfire.
Why it matters: a poor night is rarely a personal failing. Small, kind habits help, and it is fine to treat sleep trackers as a rough guide rather than a score to chase. If you are curious about the trend, see our realistic guide to sleepmaxxing.
Oura adds training tools to its smart ring
On 20 October Oura announced Cardio Effort, a weekly score of how hard your heart has worked, plus an automatic VO2 max estimate that builds from GPS walks, runs and hikes. Oura also notes that hard workouts close to bedtime can affect sleep quality and next-day readiness, and the company's blog says it has reached six million paid members.
Why it matters: the new features are about training rather than sleep, but they show how far sleep rings are widening into everyday health. If you wear one, keep late, intense workouts in mind.
It was a quieter week for mattress and bedding news, so we have kept this issue to the stories worth your time. Enjoy the extra hour on Sunday.
Rest well. You've earned it. SleepyDeepy.
