For those who are not aware, slow-wave are the hallmark of deep sleep and closely linked to the flushing the glymphatic system, which is what they are referring to in this article.
We can't create slow-waves, but we can increase their effectiveness through precisely timed auditory stimulation. I'll be posting a Show HN next week which dives into the data of how this works, but if you want to know more, there is info on our website and links to over 50 published peer-reviewed papers. https://affectablesleep.com
This paper specifically looks at amyloid clearance as a result of this glymphatic flush https://doi.org/10.1093/ageing/afad228
While many people will point to "getting more sleep" that isn't really the answer. More time asleep does not automatically mean increased glymphatic flush. Additionally, as we age, the power of the pump gets weaker, and more sleep does not help with that.
We believe the focus on counting minutes of sleep misses the point of what makes sleep truly restorative and beneficial, which are the neurological processes, and downstream physiological changes as a result. This is why we talk about restorative function, and that should be the focus of sleep health, not time.
After all, you wouldn't measure your diet based on how much time you spend chewing, would you?
