“I’ll sleep when I’m dead” – Some Anonymous Idiot

We’ve all heard this quote, most likely from an interview in a business magazine with some mega-billionaire CEO.  Of course this person is either a walking collection of crazy or some genetically gifted mutant.  I’m actually not kidding about that mutant option, as those who thrive on little sleep may have a rare genetic mutation according to a recent sleep study at the University of San Francisco.  Of course, that mutation was found in just 2 out of 1000 study participants – so rare is right.

The rest of us need sleep and need it badly.  And we probably need more of it than we think, or at least more than we’re inclined to let ourselves get by on.

In a 2002 study conducted by the National Sleep Foundation (PDF), it was found that the majority of American adults (68%) don’t get the recommended 8 hours of sleep needed for good health and optimum performance, and more than one-third (39%) sleep less than 7 hours nightly.  Strangely (yet ironically) enough, a staggering 85% of those surveyed said they would sleep more if they knew it would improve their health.

Guess what?  It does improve your health.  And your sex life, body shape, and ability to stay awake during Avatar in IMAX 3D.  It’s also the best way to improve your mood and the way you respond when you’re frustrated or stressed out.  In other words, good sleep can keep you from being a jerk AND help you look and feel better.

Lack of sleep can also have a profound effect on memory and other cognitive skills.  In an interesting study, researchers measured cognitive function in sleep-deprived, right-handed men and found that sleep deprivation has a negative effect on cognitive functions associated with "right-brained" functions such as "motor, rhythm, receptive & expressive speech, memory and complex verbal arithmetic function."
