How Much Sleep Do You Actually Need?

By four months old, babies need 10-12 total hours of sleep per night–but good luck getting them all in a row!

This can vary a lot, but if you're 12 or under, you require at least ten hours of sleep.

There's a reason you're falling asleep in class–you might need up to 13 hours of sleep every night.

You need to sleep all day and all night forever. Nothing will ever feel good again.

You're single, don't have a serious job, and live with your best friends. Sleep is for the weak.

You're still single, still don't have a serious job, and still live with other grown adults. Sleep for a week.

Try to stay asleep for as long as you can to forget the meaningless boredom of your waking life. Oh, and that person who broke up with you when you were 13? You're still not over them.

You DEFINITELY need a solid 12 hours of sleep. Although…tonight is your last hurrah before you join the rat race, right? Better stay out then grab 3 hours of sleep.

Sleep in all day. You deserve it.

Sleep and sleep. Then sleep some more. That way you won't bother the roommates you still have.

Oh, God, you never imagined living this long. Sleep scientists don't even bother to learn about people this age, probably.

You've finally settled down. You've got a big, comfy bed you share with the love of your life. Your job is lucrative, respected, and fulfilling. Just kidding, you were asleep and this was a dream.

Pretty much your whole day should be split between sleeping and staring at your oily face in the mirror.

If you aren't rich and famous by 31, your life doesn't matter. Sleep it off. Forever.
