Frequent and Unintentional Daytime Napping Linked to Higher Dementia Risk in Older Adults

I don’t have sleep apnea.
Again, its not being tired at mid-day. If I don’t eat, I don’t get sleepy at all. I almost never eat lunch at work anymore because when I do, I go down for a nap. It’s a direct causal relationship, or at the very least I can’t find any other reason for it. Lots of people have weird quirks to their biology. Probably most of us.
Its most likely just my parasympathetic nervous system (responsible for the “rest and digest” calming reflex) goes into overdrive that time of day because I tend to have a lot of energy to burn between waking and noon, and eating tells my body it can rest by stimulating the vagus nerve. Not worth doing further digging, no.
