In "SYNC: The Emerging Science of Spontaneous Order" the author (Strogatz) talks about how in a cave environment, people still take naps a little after noon. People are just as likely to be asleep at 2pm as they are at 4am. Car accidents peak around that time. People fall asleep when their basal temperature is at their lowest, and yup, guess what, people experience a body temperature dip in the late afternoon.
Basically, all the evidence he provides points to a built-in nap time. I, of course, take the physicist's side over the physician's...

There is a tendency to get tired in the afternoon, because clock-dependent alerting (which give us our diurnal sleep schedule) dips at that time. But he's arguing that the reason this is affecting people so strongly is because basically everyone is chronically sleep deprived.
