  • "Harry?"

  • "Wake up, wake up!"

  • In the last century,

  • people slept an average of nine hours per night.

  • Today, more than half the world's population

  • gets by on less than

  • seven hours of sleep per night.

  • But in an age of non-stop stimuli,

  • what do you expect?

  • To sleep is to miss out on...

  • something...

  • So, why sleep at all?

  • What if we didn't need sleep?

  • Sleep is simply one of those things

  • you just can't live without.

  • At least, not yet...

  • Your heart, your lungs, your brain

  • and your metabolism

  • all need a good night's rest to work their best.

  • Without enough sleep,

  • you increase your risk of high blood pressure,

  • depression, diabetes, obesity

  • and cardiovascular disease,

  • not to mention any infections that might prey

  • on your weakened immune system.

  • "Put that coffee down!"

  • But then, in 1965,

  • a 16-year-old stayed awake

  • for 11 days straight

  • without sustaining any permanent side-effects.

  • And in 2007, researchers tested a new drug

  • on primates that reduced

  • the negative effects of sleep deprivation,

  • and boosted their cognitive performance.

  • So the big question is,

  • "I'm on no sleep. No sleep!"

  • The average person spends

  • about a third of their life asleep.

  • In a world where we'd no longer need sleep,

  • you'd have eight extra hours to play with!

  • Would you see more family and friends?

  • Would you learn a new skill,

  • pick up a new hobby,

  • or unleash your creative potential?

  • Of course, not everyone would

  • see this as "free" time.

  • The longer you're awake,

  • the more money you'll spend and,

  • the more money

  • you'd undoubtedly have to earn.

  • Your grocery bill, for instance,

  • could easily double.

  • If the average person eats

  • three meals within 12 hours,

  • you'd probably have to eat twice as much

  • to have enough energy

  • to last you for 24 hours!

  • Along with your food consumption,

  • your fuel consumption would also go up,

  • and with it, your environmental impact.

  • It wouldn't just be from people

  • driving more often,

  • but also from people having

  • their lights on more often,

  • because everyone would be awake all the time.

  • The workaholics among us would

  • surely increase their time at the office

  • along with anyone else

  • looking to make an extra buck!

  • Of course, with more people working overtime,

  • stress levels would increase, and,

  • not sleeping would certainly

  • make the problem worse.

  • So 24-hour therapists

  • would be in high demand,

  • along with 24-hour restaurants and

  • 24-hour farmers.

  • Yeah, we would need so much more food.

  • And not just because everyone's eating more,

  • but because those of us who

  • aren't working longer hours

  • might still feel inclined to be more...

  • productive.

  • So population would increase,

  • and there would be more people to look after.

  • We'd need to train armies of first responders

  • in order to serve, protect, and save

  • a growing, restless public.

  • With more hours in the day,

  • we might be able to speed up our progress

  • and find cures to some of the world's

  • most challenging illnesses.

  • The curious minds of the world

  • would have more time to

  • innovate and explore,

  • delivering new technologies, and,

  • making fresh discoveries

  • ahead of their time!

  • Who knows?

  • We might even make it to Mars

  • sooner than expected!

  • ... Or would we just end up wasting more time?

  • There are plenty of

  • smart ways to be productive, but,

  • cutting back on sleep

  • is definitely not one of them!

  • Studies show that humans

  • are intellectually productive

  • for roughly six hours a day,

  • and that's provided we allow ourselves

  • some downtime to recharge.

  • So it's not guaranteed that a sleepless society

  • would get more done.

  • We might simply be faced with the problem

  • of having too much time on our hands!

  • And if you don't think that's possible,

  • just remember the last time

  • you had to kill a few hours of time.

  • Let's just say that

  • movies, TV, and video games

  • would become a lot more popular

  • ...along with bars and

  • definitelycoffee shops!

  • So whether you get your full 7 hours,

  • or just 40 winks,

  • your body needs to take breaks.

  • You can handle a late night once in a while, but,

  • if you go too long without adequate sleep,

  • you'll eventually break down.

  • So pick your poison:

  • coffee, Red Bull, or a new pill on the market,

  • you still can't replace sleep.

  • And why would you anyway?

  • Productivity is great, excitement is great, but

  • ...isn't relaxing on a bed pretty great too?

  • Get a full night's sleep tonight,

  • and see how refreshed you feel tomorrow!

  • Do you think you'd sleep more

  • if you could control your own dreams?

  • Well, that's a story for another WHAT IF!

"Harry?"
