You're listening to Life Kit from npr. Hey, it's Marielle. Before we start the episode, I want to thank you for listening to Life Kit and to ask you a favor. We'd love to what you think about the podcast. Help us out, tell us what you like and how we can improve by completing a short anonymous survey@npr.org lifekitsurvey. We'll also have a link in our episode description and thank you so every time I take a nap, it's the same routine. You know, I'm on my couch, my eyes start closing and I decide, screw it, I'm going all in. This nap may mess me up later, but there is nowhere else in the world I'd rather be right now. And it is happening. I don't even set an alarm. And then I wake up like four hours later feeling groggy, often a little sad and guilty for having slept so long so close to my bedtime. So look, it turns out we're actually wired to take some kind of break or rest during the day, which can include naps. Our body's internal clock, our circadian rhythm, is built to to have these natural dips.
Jade Wu
Whether it's because the midday sun is too hot for us hunter gatherers to, you know, be functioning at that time. For whatever reason, we evolved to have this little early afternoon dip. And if we sort of ride that dip and take our nap as we're feeling that, that's where we're going to get the most benefit out of it. Like, go with your body instead of against your body.
Marielle Segarra
Jade Wu is a sleep medicine specialist and researcher based in North Carolina and the author of the book hello, Sleep A. She says when done right, a nap can offer a lot of mental and emotional benefits.
Jade Wu
I like to call it kind of a performance enhancing drug without the drug. It's good for our emotion regulation. It makes us less biased towards negative stimuli and more flexible in our thinking. And things that you learned before you went and took a nap are more solidly embedded in your brain after you wake up from the nap.
Marielle Segarra
And there are a ton of physical benefits, too.
Jade Wu
So athletes will often use a nap to really boost their performance. And they'll find that they have more power, you know, they have more stamina, they feel fatigue less quickly so napping really can all around benefit our performance and our overall health.
Marielle Segarra
So okay, this made me feel a lot better. But she says it's also true that there are right and wrong ways to nap. And yeah, I think I'm doing it wrong. On this episode of Life Kit, reporter Andy Tagle talks to Jade and to a sleep physician on how and why to take better naps. They'll talk sleep science, ideal nap routines, and the importance of rest no matter when your head hits the pillow.

Takeaway 1 Naps are supplemental Sleep okay to start fellow sleepyheads, let's quickly go over some basics, like what even counts as a nap.
Jade Wu
That's actually a more complicated question than you would think. There's not really a consensus definition. That's why sometimes you see on TikTok, people are like, oh, let's play nap roulette. Is it going to be a 30 minute refresher or is it going to be a four hour journey to the astral plane?
Andy Tagle
Who knows? Let's go again. That's sleep psychologist and researcher Jade Wu.
Seema Khosla
A nap is. That's a good question.
Andy Tagle
And that's Seema Khosla, a sleep medicine physician practicing in Fargo, North Dakota, and the host of Talking Sleep, a podcast from the American Academy of Sleep Medicine.
Seema Khosla
I would think of a nap as a period of time where you are sleeping that is not at the same time as your regular sleep period. And the reason I phrase it that way is even though most of us sleep at night and we think about napping during the day, for our shift workers, they may be sleeping during the day and then may take a nap at night.
Andy Tagle
Great point to start us off, Seema. Let's all keep that in mind moving forward. Jade, anything to add?
Jade Wu
So I don't want to make it seem like, oh, naps are so awesome that you should just take, you know, quick naps all day long and not worry about your nighttime sleep. Because nighttime sleep is still the bedrock of when you get your deep sleep and the restorative continuous sleep that your body really needs. So I would start by prioritizing locking down nighttime sleep and then on top of that, think of napping like a bonus.
Marielle Segarra
Got it.
Andy Tagle
So just so we're all clear here, a nap should be a supplemental short period of sleep, an appetizer or nappetizer, if you will, to your full course sleep session that combined should help you achieve the seven to nine hours of daily sleep recommended for most adults. Now, why do we crave naps? Let's go back to that natural dip in energy. The timing of our sleep is based on two drives. The first is our homeostatic sleep drive, also known as sleep pressure, which builds from the moment you wake up until the moment you go to bed. The other is your circadian rhythm. You probably remember this from science class or any of the other many great Life kit episodes on sleep. But if not, here's a quick refresher.
Jade Wu
Your circadian system is a network of clocks. Billions of clocks, like most of your cells, have clocks. Your organ systems, your hormonal, you know, rhythms have clocks. Everything in your body runs on a clock. And all of these clocks are overseen by a master clock in your brain. And this master clock can do its job the best when it knows what time it is, and it can sort of keep time on a consistent rhythm.
Andy Tagle
And so all of our internal clocks have that natural dip in energy. But the thing is, everyone's rhythm is a little bit different, which leads us to takeaway. Two naps are not for all. Yes, siestas are sweet, but they're not always the answer or always possible for everyone. So let's check in to make sure you even need a nap. Tell me, are you sleepy or are you tired?
Jade Wu
Tired and sleepy are due to different causes, and therefore they require different cures.
Andy Tagle
Sleepy is pretty straightforward.
Jade Wu
Your eyelids are heavy, you're yawning. You're like, oh, yeah, I could fall asleep pretty quickly pretty soon. But tired, tired is everything else.
Andy Tagle
Maybe you think you need a nap, but really you're just feeling unmotivated at work or fed up with your partner. Maybe you're anxious about finances or in need of fresh air or more light, or maybe you're just dehydrated.
Jade Wu
When we make that distinction, then we know where to look for the cure. You know, do I need to drink more water or do I need to go take a nap?
Andy Tagle
As is so often the case here at Life Kit, what it comes down to is simple. Just listen to your body. For me, my body is almost always calling for sleep. I hit a quick snooze just as often as I can. For others, naps might not be desired or even possible at all. Back to that internal clock.
Jade Wu
Not everybody has to nap, and not everybody can nap. Some people's circadian rhythms just are so strongly tuned in such a way that, you know, just we do not sleep during the day. We only sleep when it's dark at night, and that's perfectly fine.
Andy Tagle
So maybe your internal master clock is set to run on a straight eight hours of sleep through the night. Or maybe you're more like me and are wound for a disco nap just about every day. Knowing which you are can help you plan accordingly.
Seema Khosla
And that may change over time, too. You know, our sleep needs, you know, in broad terms, we think seven to nine hours. But there's some variability, and we've all experienced that where you sleep for 10 hours or 12 hours when you're not feeling well, just as we, you know, sometimes if you haven't done a whole lot during the day, you haven't been really physically active or mentally active. Maybe you don't need as much sleep that night.
Andy Tagle
Now, it's important to note that there are also people who shouldn't take A nap. Like if you suffer from insomnia or other sleep disorders, experience poor quality sleep.
Seema Khosla
At night, or if you are somebody that struggles to fall asleep at night, then perhaps avoiding the nap is the right advice for you.
Andy Tagle
So if you have any concerns about your sleep, definitely consult your doctor before making changes to your sleep schedule. Now, once you've taken stock and decided it is indeed nap o', clock, we'll move to takeaway. 3. Taking a great nap is as simple as C, E, B. Ever woken up from a nap and felt more tired and then sat up and been like, wait, what planet am I on?
Seema Khosla
If you wake up from deep sleep, sometimes you feel almost drunk from sleep. The term that we use is called sleep inertia, where that sleep just follows you into wakefulness.
Andy Tagle
Sleep inertia is a sign that you're overshooting your napping mark. That can slow you down in the short term and potentially sabotage your nighttime sleep in the long run. How do you avoid that? Keep these three simple parameters in mind.
Jade Wu
We want to be consistent and early and brief.
Andy Tagle
Let's take each of those one by one. First up, C. Consistent.
Jade Wu
I mean, not haphazardly. Sometimes early, sometimes late, sometimes, you know, long, sometimes short. We want to be, you know, taking a leaf out of the Mediterranean cultures. If you're going to have a siesta, do it at the same time every day.
Andy Tagle
Then there's E for early midday.
Jade Wu
Early afternoon would be excellent.
Andy Tagle
Jade suggests aiming for a nap between noon and 3pm during the day or for the night owls and shift workers out there.
Seema Khosla
Usually we want you six hours or more before your larger sleep period is that if you're going to take a nap, have it done by then.
Andy Tagle
And finally, there's B for brief. This one might be painful if you're a fan of a long, leisurely afternoon snooze.
Seema Khosla
But if you're taking a two hour nap, that almost becomes an additional sleep period. And then you could argue that maybe you're engaging in what's called polyphasic sleep, where you're doing a little bit at night, a little bit during the day, you're not doing it all at once.
Andy Tagle
So Jade says 30 minutes to an hour tops.
Jade Wu
If you set a timer for about 45 minutes, give yourself a few minutes to get into sleep, you'll probably end up sleeping about 30ish minutes and that's pretty safe. That's good.
Andy Tagle
Seema's version of brief is even briefer.
Seema Khosla
A short nap is typically what we Recommend, you know, 10 or 20 minutes. And the idea behind that is that you probably will remain in the lighter phases of sleep rather than getting into the deeper phases of sleep, where sometimes it's a little bit harder to wake up.
Andy Tagle
A quick note here. Every phase of sleep is important. If you do any sort of sleep tracking, you might have noticed there is.
Seema Khosla
This assumption that only the deep sleep is what we want and there's something wrong if we are only in, you know, quote unquote light sleep. But the reality is that we need it all. They all have a job to do and they work together. It helps with our immune system, but it also helps with our brain.
Andy Tagle
But for quick naps, it's best and more likely to stay in lighter phases of sleep. If you find yourself falling asleep quickly and dipping into deep sleep with only 30 minutes of napping, that's actually a.
Jade Wu
Sign that you're not getting enough sleep at night. So that's just a symptom that your brain is so desperate to get into deep sleep that even a 30 minute nap will get you there.
Andy Tagle
A lot of dreaming during nap time could be another canary in the coal mine. Your body might just be compensating for not enough REM sleep during the night.
Jade Wu
Or if you really consistently and often fall asleep during the day and go directly into rem, that might mean you have narcolepsy.
Andy Tagle
All this to say again, listen to your body and do what you can to set yourself up for success. We'll get more into how to do that right after the break.

Andy Tagle
Okay sleepyheads, we're back with more Life Kit. In our quest to better naps, let's also make sure we're practicing overall good sleep hygiene, shall we? That brings us to takeaway 4 Stop committing sleep Sabotage for the very best of naps. Be aware of daytime habits that get in the way of good sleep. Alright, it's time to talk about the great big energy drink sized elephant in the room.
Seema Khosla
Sometimes when we are chronically sleep deprived, we are in survival mode. So then it's okay, I've got to get through that afternoon hump. I'm going to have some caffeine and maybe we overdo. So then that sabotages our attempts to fall asleep at night.
Andy Tagle
Do you resemble that statement? I know I do. If you want better naps, it's important to be conscious about your caffeine consumption. And we have a Life Kit episode on exactly how to do that if you're interested. But the two can coexist. For example, some people, and by some people I do mean me swear by caffeine naps. That's when you throw back a Diet Coke right before nap time. So by the time you wake up, you feel extra energized and ready to go. And there are studies that back up this practice. But Jade says exercise caution between having.
Jade Wu
Caffeine that late and having a nap. You might be setting yourself up to, you know, have difficulty falling asleep that night.
Andy Tagle
And Seema agrees. Stay mindful and curious about how caffeine affects your sleep.
Seema Khosla
And it doesn't have to be all or none, right? You don't have to have 200 milligrams of caffeine and then take a nap. You could have like 60 and then take a nap.
Andy Tagle
And then there's how we set up our sleep space. Let's say you're trying to nap in your car over your lunch break.
Seema Khosla
What does that look like and how.
Andy Tagle
Can we optimize it?
Seema Khosla
If you are intentionally going to take a nap, you is it worth bringing a pillow and a blanket and an eye mask? Right? And some earplugs.
Andy Tagle
Another tip that was hard for this napper to hear. Keep the same bedtime and wake time on weekends.
Jade Wu
Otherwise you're doing social jet lag. So you live in San Diego. So if you get up three hours later than usual on weekends, it's like you've flown from New York to San Diego and back over the course of that weekend. That does not feel good. Right? I'm sure you've done that trip. That jet lag is just brutal.
Andy Tagle
As Jade puts it, maintaining a robust circadian clock allows you to cope and recover better from all sorts of stressors. So the occasional unideal sleep situation, like actually getting on an airplane and switching time zones, for example, can be that much easier to manage. Speaking of travel, we've arrived at our final destination. Takeaway 5. Create a mini rest ritual. Because even without napping, daytime rest is crucial to nighttime sleep. This goes back to our caveman brains and that built in circadian dip in energy we all experience in the middle of the day. Honoring that pause lets your brain know it's okay to settle down at night. If you spend your whole day going 100 miles an hour, that is sending.
Jade Wu
The message to our bodies that it's not safe to fall asleep. Because the only reason why you're going, going, going all day without stopping must be because there's a saber toothed tiger on your tail, right? So if that's the case, you better not fall asleep and certainly not into deep sleep. So that's why daytime rest, even if you don't fall asleep during the day for a full nap, daytime rest is really important.
Andy Tagle
That's right. Even if you don't fall asleep. I know this is a hard one, especially if you're desperate for sleep and have precious little time before your fussy baby is up again. Or if you only have exactly 30 minutes of a lunch break.
Seema Khosla
I think sometimes if you put a time limit, that itself is stressful, super anxiety inducing.
Andy Tagle
Yeah, right.
Seema Khosla
Because you're like, okay, has it been 10 minutes?
Andy Tagle
Can I peek? Can I look at my watch? I don't know. The fix is to reframe your thinking around your rest period to start some rebranding could be helpful. Like, what does it take exactly to achieve a power nap?
Seema Khosla
I think it's because we say it's a power nap.
Andy Tagle
Okay. We just declare it. Declaring it makes it so.
Seema Khosla
I think so. I think so. Because I'm not sure that there has been any rigorous study on it. And I think it's more because we believe that it restores us. So whatever the duration of time is, a short amount of restorative sleep that makes us feel better afterwards.
Andy Tagle
Okay. Simple enough. I'm declaring all my naps moving forward. So option one, fake it till you make it. Option two, maybe you don't have to sleep at all.
Jade Wu
If I fall asleep, great. If I don't fall asleep, also great. But what I'm not gonna do is Check my email, scroll through social media, do chores, or do any of those things that further overstimulate me. What you need is true rest. So even if you don't fall asleep, even if you just kind of hang out in a meditative state or do some mindfulness practices or even just let your mind wander, we know from brain scanning studies that those states are really restful and really special and can be rejuvenating in a similar way that a nap can be rejuvenating.
Andy Tagle
If you have a nighttime routine that helps you wind down, you can do.
Seema Khosla
Something similar, sort of like a short version of that to ease you into your nap. Particularly if it's the same place, right, that if you work from home and you are able to sleep in your bedroom and you usually do like a 10 minute meditation before you go to bed, maybe do a five minute meditation before you take a nap.
Andy Tagle
Jade plays Beethoven to cue nap time for her kids and herself. Seema is a fan of box breathing.
Seema Khosla
You breathe in for 4 seconds and you hold for 4 seconds and you breathe out for 4 seconds and you hold for four seconds.
Andy Tagle
Audiobooks and podcasts are another favorite for winding down. We might be able to help you there.
Jade Wu
And I'm not just saying that because we're on a podcast right now, but truly, NPR is a really good pre bedtime podcast for, you know, station.
Andy Tagle
No matter what relaxation method you choose, remember you can only do what you can do.
Jade Wu
Sometimes it's not possible to nap and rest in the ideal way that we've talked about, but it's always possible to prioritize your health and wellness, even in little ways.
Andy Tagle
Don't let perfection be the enemy of good. Nap when you can, where you can the best you can. But the key here is you just really need and deserve to rest, even.
Jade Wu
If it's just for just a tiny bit of time. Get out of your head, into your body and whatever tasks you can do. Being mindful. Do that, you know, as you walk from your car to the office, from your car to the grocery store. Walk mindfully, be in that moment with your body and that goes a long way.
Andy Tagle
Okay, let's recap softly and slowly just in case any of you are using this podcast to settle down for your early afternoon snooze. Takeaway 1 Naps are supplemental to your nighttime routine, not a replacement. Takeaway 2 Not everyone needs a nap, so if it's not happening, don't stress it. Takeaway 3 Aim for naps that are C, E, B consistent, early and brief. Takeaway 4. Stop committing sleep sabotage for the very best of naps. Be intentional about all of your sleep takeaway. 5. Daytime rest is crucial for nighttime sleep. Even if a nap isn't possible, make time for a daily ritual of rest.
