He’s not depriving himself of sleep, he’s just following an unusual sleep schedule, right? Which I would guess is not a big deal for longevity (AFAIK the research is agnostic on this question but I’m not too familiar with the research).
Dumbledore was lengthening his circadian cycle by 2 hours per day. But then Harry was using the Time-Turner to go back 6 hours per day. That leads to a net of the sleep schedule going back 4 hours per day, so I think Sinclair was taking all the above into account.

Not exercising is a big deal, though.
Harry’s circadian rhythm was artificially altered; at least if Dumbledore is telling the truth.
