Why Do We Sleep?

child waking up with alarm clockHave you ever sat down and really thought about this question – “why do we sleep?”  Considering we live in a society which hardly ever stops and for those of us working 24/7 who run on very little sleep, I think it’s a pretty powerful question.

I know after working shift work for over two decades my cognitive function has definitely been affected, not to mention so many years of feeling constantly exhausted and “wired” as a result of my body running on adrenalin.

So I’ve been doing a bit of research lately and stumbled across this great TED talk by Neuroscientist Professor Russel Foster who goes into detail to help answer this question – “why do we sleep?”

I highly recommend taking the time to watch this really informative 20 minute video (or you can view it as a transcript if you’d prefer to read instead of watching it).  In fact Professor Foster even talks about “us” (shift workers) during parts of the presentation!

Of course if you’re running really tight on time you can always fast forward 8.4 minutes into the video when he goes into detail on some of the effects of constant sleep deprivation – in particular how it affects those of us working 24/7 which is right up our alley.

Hope you enjoy it!  Just click on the link below :-).
