While I'm not aware of any studies, it was very common historically to go to sleep shortly after sunset, wake for a few hours in the middle of the night (many children created during these hours), then sleep again until sunrise.
Also, siesta countries like Spain and Italy, have pretty strong life expectancy. Seems like an indicator that afternoon napping probably isn't harmful.
Seems like something worth studying in a controlled manner.
