Deep Sleep May Be the Best Defense Against Alzheimer’s

My personal theory / opinion in how I know I slept deeply is whether I had a dream that felt like a fairly long period. There was a point in my life where I literally had no dreams and slept like I was passing out. I realized that this was greatly affecting my long term memory. I went and made incremental steps in getting my sleep better and thankfully was able to start dreaming again, and even got to some points where my dreams became lucid, like being in inception. Anyways that's just my personal indicator on whether ive been sleeping deeply.

You're talking about REM sleep, not deep sleep. The article is talking about (I believe) the N3 stage of non-rem sleep, which is when the surrounding space around cerebral arteries expand and cerebral spinal fluid outside those arteries with flush out toxins

During this stage of sleep, neurons also fire in unison at a slow frequency on the order of 1Hz

I don't think that happens in REM sleep, which actually looks more like wakefullness than the N3 stage, but with certain aspects of cognition shut off (like the rational part, and the motor activation part)

Thanks for pointing this out! This definitely makes. me wonder if there's a way for us to tell whether we had adequete deep sleep without using an app or some external machine. My points about REM/Dreaming was that I could notice these things naturally without aid.

get a minimal activity monitor, without any "smart" functions. you can get ones that charge for 15m every 5 days now. (trying not to promote a particular product)

It might be possible to get that indirectly through cognitive tests taken throughout a person's life and see how they progress

Sleep quality deteriorates rapidly after age 45, at least from what I was told by the Dreem2 tech support a while ago. My understanding is this involves the amplitude of brain waves during primarily the N3 stage, while physical exercise has been shown to enhance that amplitude, e.g. walking 3 miles a day

The Dreem2 headband does have the ability to enhance the amplitude and duration of N3 brain waves also, by using timed pulses of pink noise in a feedback loop

Though I don't think that feature was available to consumers inside the USA cuz of FDA regulation BS
