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
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)
