So those are the three main things. These are established facts. I don't think the
scientific evidence is conclusive and those are the things we take into
consideration when we try to apply the knowledge to the practical or operational
situation. Any questions on that?
People say, "Can you accumulate a debt for a year?" We don't know because
those studies haven't been done. But there's no evidence whatsoever that says
"No, it levels off," or "No, it changes." All the evidence says that you keep
accumulating a debt as long as you keep losing sleep below your specific daily
requirement. There's no evidence that you can change this. I suppose you
could ski or play basketball as opposed to just sit in a hot room and that would
make a little difference but that doesn't change your sleep requirement.
Anybody got any questions?
l've got a question. Napping: does that in any way alleviate the sleep debt?
Let's say you have a 4O-hour sleep debt and you have a ten-minute nap. So now
your sleep debt might be 39 hours and 50 minutes. lt wouldn't make any
difference there. A lot of the napping is done after lunch. Most people, and
especially younger people - and I don't know what the average age is in this
group - but younger people have strong clock-dependent alerting late in the day.
So you have sort of an illusion. You happen to take a nap just before the clock
turns on. ls the alerting partly a result of the nap or not? Mostly not, but I would
say until proven otherwise that a nap, if it is good sleep (which it usually isn't) is
minute per minute doing what sleep would do, but it's usually nowhere near the
total amount that you require.
