For many of us, more hours of shut-eye at night just doesn’t seem to be in the cards. Is there anything we can do? Yes.

**Naps. Wonderful, glorious naps.**

**They’re not a full-on substitute for lack of sleep but they can do much more than you think and in less time than you’d guess.**

Without them, you’re going to be a mess. Here’s why.

## Wanna Be Dumb And Ugly?

**Lack of sleep not only makes you** [**ugly**](http://www.bakadesuyo.com/is-there-really-such-thing-as-beauty-sleep) **and** [**sick**](http://www.bakadesuyo.com/2011/09/why-do-some-people-get-sick-so-often-and-othe/)**, it also makes you dumb**: missing shut-eye makes [6th graders as smart as 4th graders](http://www.bakadesuyo.com/2014/03/how-to-make-your-kids-smarter/).

And if that’s not enough, **lack of sleep contributes to an early death.**

Via [Night School](http://www.amazon.com/gp/product/B00IW3UI7C/ref=as%5Fli%5Ftl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00IW3UI7C&linkCode=as2&tag=spacforrent-20&linkId=FDM2FFQCL2ANHXLF):

**Maybe you think you don’t need all that much sleep. You’re wrong.**

[Less than 3% of people](http://www.bakadesuyo.com/2012/01/do-some-people-only-need-a-few-hours-of-sleep/) are actually 100% on less than 8 hours a night. But you feel fine, you say?

**That’s the fascinating thing about chronic sleep debt. Research** [**shows you don’t notice it**](http://www.bakadesuyo.com/2011/04/how-little-sleep-can-you-get-away-with/) – even as you keep messing things up.

In her TED talk, Sara Mednick, author of [Take a Nap! Change Your Life](http://www.amazon.com/gp/product/B00B8UDC1U/ref=as%5Fli%5Ftl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00B8UDC1U&linkCode=as2&tag=spacforrent-20&linkId=JPJFOVDTTDM5534M), gives the rundown:


Now here’s the part you’ve probably never heard:

**Eight hours might not even be enough.** Give people 10 hours and they perform _even better_.

I know what you’re thinking: **_10 hours a night? I don’t have time for that. I barely have time to read this post._**

Is there a compromise?

**Naps.**

Can closing your eyes for a few minutes really make that much of a difference? Keep reading.

## NASA Says You Should Sleep On The Job

**Research shows naps** [**increase performance**](http://www.bakadesuyo.com/2011/12/whats-a-fun-way-to-increase-alertness-and-per/)**. NASA found pilots who take a 25 minute nap are 35% more alert and twice as focused.**

Little siestas helped people across a [whole host of measures](http://priceonomics.com/the-nasa-studies-on-napping/). Improved reaction time, fewer errors…

**And naps make you happier**. Studies show we can process negative thoughts quite well when we’re exhausted — just not the _happy_ ones.

What’s not to love? I know. You’re busy. You’ll just have another cup of coffee. Sorry, **research shows** [**naps beat caffeine**](http://www.sciencedirect.com/science/article/pii/S0166432808002416)**.**

**So how do you nap the right way? How do you get the results you want with minimal effort? Here’s what science says.**


## The Perfect Nap For You

Whatever your limitations and desires, there’s a nap for you. Looking at research from [Richard Wiseman](http://www.amazon.com/gp/product/B00IW3UI7C/ref=as%5Fli%5Ftl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00IW3UI7C&linkCode=as2&tag=spacforrent-20&linkId=FDM2FFQCL2ANHXLF) and the [WSJ](http://online.wsj.com/news/articles/SB10001424127887323932604579050990895301888), here’s a breakdown.

Which one describes what you need?

**1) “I Just Need To Be More Alert And Focused”:**

_Take a 10-20 minute nap._ You’ll get a boost in alertness and focus for 2 hours or more, pay off a little sleep debt and even reduce blood pressure.

**2) “Brain No Working. Need Smartz”:**

_Consider a 60 minute nap._ You’ll get all the benefits of the 10-20 minute nap while also improving memory and learning.

But be warned: 60 minute naps cause grogginess.

**3) “I Want It** **_All_** **, Baby”:**

_Take a 90 minute nap._ This allows your brain to experience a complete sleep cycle.

You’ll get the full whack: increased alertness, memory, learning, creativity and performance — with no post-nap grogginess.

**4) “I Don’t Know What I Want But You’ve Scared Me Into Napping And I Don’t Have Much Time”:**


_Go with 10 minutes._ It beat 5, 20 or 30 minute naps in a comparative[research study](http://www.bakadesuyo.com/2010/02/how-long-should-you-nap-for/).

**5) “I don’t have enough time to tell you how little time I have”:**

[_No nap is too short_](http://www.bakadesuyo.com/2012/01/5-ways-to-make-your-naps-blissful-and-awesome/)_:_ “A 2008 study showed that even a nap of a few minutes provided benefits. Just anticipating a nap lowers blood pressure.”

Got more questions? I have answers:

* **When is the best time to nap?** Salk Institute researcher [Sara Mednick](http://www.amazon.com/gp/product/B00B8UDC1U/ref=as%5Fli%5Ftl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00B8UDC1U&linkCode=as2&tag=spacforrent-20&linkId=CKDP2FPQBIAFFBJR)generally recommends you **nap approximately 6-7hrs after waking**.

* **Trouble falling asleep?** [Write down any worries](http://www.bakadesuyo.com/2011/10/how-can-you-stop-worrying-about-projects-at-w/) and think positive (but not exciting) thoughts. **Trying** **_too_** **hard to sleep is counterproductive.**

* **Worried you won’t wake up in time?** [Richard Wiseman](http://www.amazon.com/gp/product/B00IW3UI7C/ref=as%5Fli%5Ftl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00IW3UI7C&linkCode=as2&tag=spacforrent-20&linkId=FDM2FFQCL2ANHXLF) recommends**a cup of coffee immediately** **_before_** **napping**. The caffeine will kick in 25 minutes after you lay down.

## Sum Up

We’d all be better off with 10 hours of sleep a night — but that’s not going to happen for most of us.

**Naps can boost performance and help make up for some of the problems sleep deprivation can cause.**
