#32> “Although the study found inadequate sleep duration was not an issue in brain atrophy in this study, we cannot say there is no association,” she said, noting that a previous CARDIA study showed that shorter sleep was associated with worse white matter integrity, indicating lower cognitive functioning. That quote seems to directly contradict the headline.
The subtitle is UCSF-led study finds that insomnia, but not lack of sleep, may hasten brain shrinkage .
Yes. Let's use that above.
Re: Insomnia, but not lack of sleep, may hasten brain shrinkage: study
#33I'm approaching midlife and noticing the quality of my sleep has declined. I can't sleep in anymore. Sometimes I'm waking up in the middle of the night occasionally and something I'm wide awake because I'm thinking about work or something like that. Very frustrating. Another reminder to try to pull myself away from the screens late at night.
what works for me in this case is to pop in a single ear bud and turn on an audio book I've already listened to.
because there is a narrative, it shuts down rumination. because there's nothing novel, my brain is quite happy to drift off to escape the tedium.

From the public results only[1] (I don't have a copy of the whole study) they studied the following things looking for correlation with brain decline: * short sleep duration * sleep quality * difficulty initiating sleep (DIS) * difficulty maintaining sleep (DMS) * early morning awakening (EMA) * daytime sleepiness They only found that the middle four were correlated. I don't know what exactly "sleep quality" is but t…

Re: Insomnia, but not lack of sleep, may hasten brain shrinkage: study
#35I sometimes wonder what damage 20 years of undiagnosed sleep apnea has caused. My sleep report showed 50 incidents of breathing issue per hour on average. I finally got a CPAP and it has literally made a world of difference to my life. Now I hear my toddler snore and hope that he doesn’t have it. At least, I can intervene early.
When I am 86kg, I have quite heavy sleep apnea. When I am 83kg, I don’t. Everyone has different possible actions, because for some it is due to the shape of the nose cartilage, for others it’s the throat, but discovering that made a world of difference. I wake up in the morning and I’m awake. And courageous. It’s incredible.
Lucky you. I had textbook symptoms of sleep apnea four years ago with a BMI of 19.
Due to COVID I could not get tested until my BMI was 23.5. The air pressure I was prescribed was ludicrously wrong and after a couple of years of tweaking it I'm still not sleeping great, but it's a massive improvement over receiving no therapy.

Two low impact things to try are: * A very small amount of melatonin. .300 to .500 mg. * Breathe right strips, these increase airflow Other health issues can also cause wakefulness.
Don't forget: Try pausing caffeine intake.

My god, this is not only exactly what I've done for years, but you described it in exactly the same way I describe it when telling people about it, almost word for word.

Also, worth saying: these things were based on self-reported data, which is basically crap.
>To estimate the effects of sleep quality on the brain, the researchers surveyed approximately 600 adults on how well they slept. The participants were asked the same questions five years later and underwent brain scans 10 years after this.
This is press-release science. Maybe the latter three things you can remember, but I have sensors and whatnot in a fancypants mattress (i.e. I'm highly motivated to know), and my subjective opinion of my prior night's sleep is pretty uncorrelated with what they say. I couldn't begin to tell you the quality of my sleep from a week ago.

How’s the noise? Do you have a partner? I do day and night apnea and love to try a CPAP but my partner needs a quiet room to sleep.
What features/specificities should one consider to choose a model? Can I buy second hands, does some parts wear off?
Maybe should get one for when she don’t sleep at home, I’d love to feel rested at morning sometimes.

My issue is I seem somehow wired to wake up early. I sleep better when I go to bed earlier. Screen use seems to have nearly no impact on my sleep, and what has the most impact is the type of screen usage (i.e. reading news, books & watching film is fine, but instagram/tiktok before bed tends to lead to worse sleep for me).
