Slow Wave Sleep % Loss Is Associated With An Increased Dementia Risk

Recommended Posts

Thanks for sharing this Michael. It is fascinating (and scary) to see how SWS declines during aging.  SWS loss being associated with dementia should certainly make people raise an eyebrow. Your most recent data of SWS being nearly 25% is impressive and is quite youthful - kuddos to you for being able to increase it so much over the past 5 years! It is interesting to see how your data shows that a lower bodyweight is linearly associated with an increase of SWS. I wouldn't have necessarily expected that since a lot of CR practitioners report difficulties with sleep, myself included. 

While many of my biomarkers of health are youthful, my sleep data doesn't reflect this. It is shown below (I wish I could figure out a neater way of exporting my Oura data). Sadly, my data is not headed in the right direction.
