Why Sleeping Through The Night May Not Be 'Natural'

It's undeniable that we need proper sleep not only to maintain our physical and mental health but also to function in our everyday lives. We consider eight uninterrupted hours of rest the marker of a healthy lifestyle - but is that really all that constitutes 'proper sleep?'
