Yes..had this occasionally when younger...now at 77 I sleep less ...main sleep is 4 hours...but I know this and if my body tells me to slow down any time during the day I take a nap,,,if driving I pull over and park in the shade and take a half hour nap.
Funnily enough, I’m going through chemo, am house-bound with nearly zero activity ... and that’s about how I’m (naturally) treating sleep right now myself. I’m more like 40 than 77, but when my body says it’s time to shut down ... it’s nap time, and they’re glorious.
