Sleep Sweet spot. Researchers found biological aging was lowest at 6.5-7.8 hours of sleep

What’s happening: A new study linked short and long sleep duration to accelerated biological aging across the brain, metabolism, immune system, liver, lungs, and skin.

Sweet spot. Analyzing 500K+ UK Biobank participants, researchers found biological aging was lowest at ~6.5–7.8 hours of sleep, varying by organ system and sex.

Fast-forward. But sleeping under six or over eight hours increased biological aging, disease risk, and all-cause mortality. Bad news for the third of Americans who are sleep-deprived, short slumbers showed strong links to cardiovascular disease, diabetes, obesity, depression, and chronic pain.

Beyond recovery. An often overlooked pillar of health, sleep is foundational for well-being and longevity. As consumers wake up to this reality, circadian wellness is gaining — from wearables and recovery tech to specialized lighting, diagnostics, and health

1. For many years, 8 good hours was considered optimal

I do well to reach the 6.5 at the low end of the scale.

2. hmmm. seems like a lot of room for cause/effect error.

3. Yes, especially when we live into old age where everything begins to be compromised healthwise

compared to a young, healthy adult. I haven't read the whole study but there should be age categories included with future studies.

4. Until I cought covid, I was "sleep deprived"

Now I average 6 or 7. Tried everything before. Ironically long covid is sort of resetting my internal clock. But there are other side effects that aren't so great. I'd rather go back to 4-5 hours a night and not have had covid.
