How much sleep do we really need to work productively?
> <i>“Sleeping 8.5 hr. might really be a little worse than sleeping 5 hr.”</i><p>How can people even take this kind of pseudo-science seriously?<p>If I sleep for 5 hrs, I'm a complete zombie during the day, unproductive and depressed.<p>If I sleep for 8.5 hrs (which is how long I sleep naturally), I feel great, productive, and happy. I get way more done.<p>There are all sorts of studies showing all the negative effects of not getting enough sleep -- that sleep-deprived doctors, for instance, are basically acting under an impairment equal to a few drinks of alcohol.<p>The idea that people in general are getting too <i>much</i> sleep is really quite preposterous.
