Researchers at Sweden's Karolinska Institute assessed participants' sleep across five dimensions -- chronotype, duration, insomnia, snoring and daytime sleepiness -- and later scanned their brains using MRI to estimate biological brain age through machine learning models. The results? For every point decrease in healthy sleep score, the gap between brain age and chronological age widened by approximately six months. Those in the poorest sleep category had brains that appeared roughly one year older than their actual age.
Night-owl tendencies, sleep duration outside the 7-8 hour sweet spot and snoring were particularly strongly linked to brain aging. The researchers measured low-grade inflammation using biomarkers including C-reactive protein levels and white blood cell counts. Inflammation accounted for more than 10% of the association between poor sleep patterns and brain aging. The glymphatic system, which clears waste from the brain primarily during sleep, may also play a role, the research added.

Funny, my 5 hours a night ritual, and I should look like Dorian Gray. I sleep when I am tired, and wake when I'm done. The only times I do the 8 hour mandatory sleep or die thing is when I am ill. Funny that.

This is the practical question. Are these bad effects cumulative or based on some recent time window? That is, can someone who had negative sleep but then follows good sleep behaviors for some time reach the same state of health as someone who had good sleep behaviors all along?

It can't be reversed but it can be mitigated to a degree.
As someone who was diagnosed with Parkinson's Disease (PD) about five years ago I can tell you that one of the most impactful effects of that disease is *not* the tremors but the sleep disruption. A fairly high percentage of PD suffers go on to develop dementia and I'm pretty sure that this progression is hastened by the fact that sleep is so disrupted and limited.
My mitigation for the effects of sleep deprivation associated with my PD is creatine mo
Not too concerning (Score:2, Troll)
The study awarded a point for each of five attributes. No real differences between 5 points and 4 points. Even at zero points, subjects were approximately 1 year older than the the best groups. Study looked to take ~ 10 years. Naive assumption (linear relationship) says over 30 years an additional 3 years of aging. Lots of things to worry about, but worrying your 90 year-old brain looks like it is 93 would not be at the top of my list. Of course, sleep is important, but this is not a doom and gloom res
Untreated sleep apnea (Score:1)
About 8% of all US men over 40 use a CPAP to treat obstructive sleep apnea. (I'm one.) I would bet that at least 40% of all US men over 40 have it, and the incidence only increases as you get older. But with few getting it diagnosed and treated, dementia and Alzheimer's rates are sure to rise. It's partially weight, and partially the structure of your throat. Some GLP-1 drugs are designated to treat obstructive sleep apnea (through weight loss).

"Citation needed" from multiple high-quality peer-reviewed studies.
If things were as bad as you imply, nearly everyone in most big cities would be suffering noticeable health effects. If not "nearly everyone" then at least a huge percentage. The number of people complaining about bad health effects is small enough that your claims fall under the "extraordinary claims require extraordinary evidence" rule.

Seriously.
I know firsthand that bad sleep does a number on you, what I need to know is how to sleep well. In over 40 years I haven't managed so far.

My response to the endless stream of sleep damage reports - not directed toward you or anyone other than the Sleep 8 hours, or you DIE! people.
I must have died 20 years ago. I sleep 5 hours a night, I dream answers to problems in my sleep. So I'm completely demented. 8^) Oh, and I enjoy working, apparently a real killer as well. All the things that kinda sound like the proverbial "Everything you believe is wrong" mantra

an unanswerable question since everyone is different but here are the basics to try out:
eye mask
white noise generator of some sort
weighted blanket
having your bedroom be colder than normal
melatonin/seratonin can help
for some people marijuana can help quell thoughts, for others it makes them race
some people need zero screen time, some like myself will fall asleep easier watching something
also look into actually treating your anxiety. medication can help, therapy can help
maybe you just need a new job to give
