Even adjusting for age, sex, cohort, genetic factors, smoking status, sleeping medication use, antidepressant use, and anxiolytic use, each percentage decrease in deep sleep each year was associated with a 27% increase in the risk of dementia.

I guess that's a good thing for me. I've had severe insomnia for my entire life (I average 2-4 no sleep nights per month & ~5 hours per night when I do sleep), so I assume my brain/body adjusted to ensuring the most amount of deep sleep possible 😂
No wonder I don't hear anything when I'm sleeping!
