Tips for how to clean and refresh your duvet, including the duvet insert and duvet cover.

Sleeping in a freshly washed and made better is nothing short of heaven. And if you sleep with a duvet, it can be hard to keep it feeling fresh.

A duvet "is the French word for down ( a layer of fine feathers that rests under the exterior feathers of geese and ducks), reflecting the traditional fill of this bedding item that originated in Europe", according to the Sleep Foundation. These days, a duvet is typically two parts: an insert (which can be filled with down, cotton or synthetic material) and a cover that the insert is placed into.

Over time, your duvet insert can also become lumpy and flat. Giving it a good cleaning and re-fluff can bring it back to life.

How do you clean a duvet?

Washing your duvet regularly prevents allergen buildup and maintains the freshness of your bedding.

"For most families, a duvet should be washed at least annually; however, as a general rule, washes that occur every 3-4 months are recommended for those who use their duvet year round, have allergies or experience any stains/odors in their duvet," Isabella Flores, a Professional Organizer & Cleaning Expert at Sparkly Maid San Diego, tells Upworthy.

She explains that when choosing what type of duvet material to purchase, you will want to consider how often you plan on washing it.

"Duvets made from synthetic materials such as polyester/microfiber can be washed more frequently than those made from down/feather, as they do not lose their loft and retain their warmth with repeated washing," she adds.

And you should clean your duvet cover much more frequently.

"A duvet cover should be cleaned every week or so," Olivia Parks, Owner + Lead Organizer at Nola Organizers, tells Upworthy. "Even though the cover protects the insert, the insert still collects body odor, sweat, body oils from lotions or other body products, crumbs if you eat in your bed, dog hair or cat hair, and more."

How often should a duvet be replaced?

Your duvet can last a long time, but it also depends on the material it's made out of.

"Quality down duvets last 15-20 years, while synthetic fills max out at 5-7 years before the fibers break down and lose loft permanently," Matt O'Connor, Co-founder and CEO at NoScrubs.com Laundry Delivery, tells Upworthy. "Material absolutely matters because down is a three-dimensional structure that rebounds, while polyester is essentially crimped plastic that eventually fatigues and compresses. Replace when you notice cold spots (filling has migrated), when the fabric starts showing wear on the corners, or when fluffing no longer restores volume overnight."

He adds that one way to tell if it's time to replace your duvet is to stick it in sunlight and look for dust puffing out when you pat it.

"That's fragmented fill material, not just dust, meaning the internal structure is degrading," says O'Connor. "Most people replace too early because they don't know maintenance tricks, but once you see structural breakdown, no amount of washing fixes it."

4 tips to refresh your duvet

Make your duvet cover feel brand new with these helpful tips:

Tip #1: Wash and dry it properly

It's important to wash your duvet on the right setting.

"To re-fluff and restore loft, wash your duvet on a gentle cycle in cold water with a small amount of mild detergent and dry on low heat," says Flores. "Adding 2-3 wool dryer balls or clean tennis balls to the dryer will assist in breaking down clumps and restoring loft, allowing your duvet to become plush once again. Make sure it dries completely to avoid developing mold and mildew."

Tip #2: Fluff and massage your duvet

There are a few proper ways to fluff and shape your duvet.

"Place your duvet flat on a bed/table and manually manipulate any lumps, separating and redistributing the filling by massaging with your hands," Flores explains. "For particularly stubborn areas, use a lightly pressed rolling pin covered in a towel and roll to help break apart and redistribute the filling. Manual fluffing can help restore an even distribution of the filling and improve the overall comfort of your duvet."

Tip #3: Stick it in the freezer

Another way to refresh your duvet is to put it in the freezer.

"Put your duvet in a large garbage bag, seal it, and freeze for 24 hours, then immediately bring it into a warm room and vigorously shake it while still cold," says O'Connor. "The temperature shock causes the fill fibers to contract then rapidly expand, breaking static bonds and clumping."

Tip #4: Give it some fresh air

Finally, prevent it from becoming musty with some exposure to fresh air.

"Hang your duvet outside during a breezy, dry day to allow the wind and sun to naturally dissipate remaining odors, restore the duvet's freshness and encourage the filling to regain its original loft," shares Flores. "If the weather prohibits hanging the duvet outdoors, hang it indoors near a window with an open window or turn on a fan to circulate air."

Gen Z is the first generation less cognitively capable than their parents but Denmark has a solution

"Since the late 1800s, every generation has outperformed their parents."

Gen Z is the first generation less cognitively capable than their parents. Denmark has the solution.

Nearly every parent hopes their child will be better off than they are: smarter, more secure, and more well-adjusted. Many parents see this as a stamp of successful parenting, but something has changed for children growing up today. While younger generations are known for their empathy, their cognitive capabilities seem to be lagging behind those of previous generations for the first time in history.

Dr. Jared Cooney Horvath, a teacher turned cognitive neuroscientist who focuses on human learning, appeared before Congress to discuss concerns about cognitive development in children. In his address to the members of Congress, he says, "A sad fact that our generation has to face is this: our kids are less cognitively capable than we were at their age. Since we've been standardizing and measuring cognitive development since the late 1800s, every generation has outperformed their parents, and that's exactly what we want. We want sharper kids."

Horvath explains that the reason this happens is that each generation has gone to school longer than the previous generation. Gen Z is no exception to the longer duration of time spent in school, but they're the first ones who aren't meeting this normal increase in cognitive development. According to the cognitive neuroscientist, the decline is due to the introduction of screens in the classroom, which started around 2010.

"Across 80 countries, as Jean was just saying, if you look at the data, once countries adopt digital technology widely in schools, performance goes down significantly. To the point where kids who use computers about five hours per day in school for learning purposes will score over two-thirds of a standard deviation less than kids who rarely or never touch tech at school," Horvath reveals.

In most cases, the decline in performance doesn't result in better strategies. The neuroscientist shares that the standardized testing has been adjusted to accommodate lower expectations and shorter attention spans. This is an approach that educators, scientists, and researchers went to Capitol Hill to express wasn't working. But not every country is taking the approach of lowering standards to meet lowered cognitive ability. Denmark went in the opposite direction when it realized their students were slipping behind.

France24 recently interviewed educators in Denmark following their seemingly novel approach to students struggling with cognitive development. Since the beginning of the 2025/2026 school year, Denmark has not only been having students turn in their cellphones, but they've also taken tablets, laptops, and computers out of the classroom. No more digital learning for the majority of the school day. Danes went old school by bringing back physical textbooks, workbooks, and writing assignments. The results have been undeniable. Even the students can't seem to deny the success of the countrywide shift in educational approach.

"I think the biggest issue has been that, because we kind of got rid of the books and started using screens instead, that we've noticed that a lot of the kids have trouble concentrating, so it's pretty easy to swipe with three fingers over to a different screen and have a video game going, for example, in class," Copenhagen English teacher, Islam Dijab tells France24.

Now, instead of computers being part of every lesson, Denmark uses computers very sparingly and with strict supervision. One student says that it has been nice not having screen time at school because she loves to read and write. But it wasn't just the lack of attention span children were developing, they were also developing low self-esteem and poor mental health due to the amount of time spent on devices.

The data showing the negative impact of screens on teens' brains has prompted a nationwide change in Denmark that extends outside of the classroom. Afterschool activities are eliminating or extremely limiting electronic use. There is also a national No Phone Day that encourages everyone to put away their devices for the day, and Imran Rashid, a physician and digital health expert, is petitioning parliament to ban social media use for children under the age of 15. The no phone movement in Denmark is a nationwide effort that hopes to right the ship before another generation feels the effects.

Experts share 8 items that should 'never' be refrigerated, and some of them are a bit shocking

"Hot sauce. Having it chilled just seems fundamentally wrong."

A woman is surprised as she peers into a refrigerator. A jar of peanut butter.

Imagine scrolling through Instagram Reels when a meme pops up featuring a cartoon jar of mustard. The caption reads, "Whatever you do, don't refrigerate me!" After getting past the idea that a jar of mustard could communicate, it left a few people wondering, "Does mustard not belong in the fridge?"

Of course, this wouldn't be the first time experts decided where condiments or other food items should go. In an article by Upworthy colleague Jacalyn Wetzel titled "Heinz triggers all of the internet with a single tweet: 'Ketchup. goes. in. the. fridge!!!'" the stance seems pretty clear. She shares photos from an X user showing the back of the bottle, which clearly reads, "Refrigerate after opening." A few users continue to argue, asking questions like, "So why is it on shelves in supermarkets and shops, then?" Heinz actually replied, "Where do you keep your soft drinks, Dave?"

See on Instagram

Now, newer lists have begun circulating that identify certain food items that shouldn't be kept in the fridge. Some of these may come as a surprise, especially to non-chefs or people without food expertise:

TOMATOES

In a Southern Living article titled "12 Foods You Should Never Keep in the Fridge," writer Kaitlyn Yarborough is clear that tomatoes belong on the counter. Yarborough explains, "The cold, humid atmosphere inside the fridge can affect the texture of your tomatoes before you have a chance to use them. Just make sure to keep them out of direct sunlight."

POTATOES

Again, this is largely a texture issue. On KitchenAid's website, they suggest storing potatoes "in a paper bag at room temperature" to avoid making them "gritty and overly sweet due to the moisture."

PEANUT BUTTER

In another surprising twist, experts at KitchenAid say peanut butter doesn't need to be refrigerated for up to three months: "Peanut butter maintains its spreadable consistency at room temperature for three months, after which refrigeration is recommended."

AVOCADOS

This only applies to avocados that haven't been sliced yet. If you're ready to use them and don't want to "slow down the ripening process," Yarborough suggests storing them at room temperature: "Once cut open, store any halves in a Ziploc plastic bag or container in the fridge."

PEACHES (AND OTHER STONE FRUITS)

Perhaps more surprising on the list were certain types of fruit that many might have assumed should be refrigerated. Yarborough urges people to leave peaches and other "stone fruits," such as plums and nectarines, at room temperature until they ripen. "You can stick stone fruits in the refrigerator once they're ripe, but keep in mind that the dry air will eventually dehydrate and wrinkle the fruit," she writes.

BANANAS

KitchenAid also offers advice on keeping bananas from browning too quickly, even suggesting storage options beyond the counter: "Your best options include an open countertop, a pantry or a dedicated banana hook."

FRENCH FRIES

To mix things up a bit, in a Reddit thread titled "What food item should never be refrigerated?" one foodie offers this advice: "Leftover French fries. It's like a mouthful of abomination no matter what you do to reheat them after their trip to the cold tomb."

HOT SAUCE

This one made quite a few lists, with some pointing out that, by name alone, it seems obvious it shouldn't be cooled. One Reddit user writes, "Hot sauce. Having it chilled just seems fundamentally wrong."

The food experts at KitchenAid agree: "To preserve the rich flavor and intense heat of your hot sauce, it is recommended to store it in the pantry unless otherwise specified on the label."

Helicopters dump 6,000 logs into rivers in the Pacific Northwest, fixing a decades-old mistake

Forty years ago, restoration workers thought logs were the problem. They were wrong.

Restoration workers now see how "critical" wood is to the natural habitat.

For decades, river restoration in the Northwestern United States followed a simple rule: if you saw logs in the water, take them out. Clean streams were seen as healthy streams, fast-moving water was seen as optimal, and wood was treated like a "barrier" to natural processes, particularly those of the local fish.

Now, helicopters are flying thousands of tree trunks back into rivers to undo that thinking.

In central Washington, one of the largest river restoration efforts ever attempted in the region is underway. More than 6,000 logs are being placed along roughly 38 kilometers, or 24 miles, of rivers and streams across the Yakama Reservation and surrounding ceded lands.

Nearly 40 years ago, Scott Nicolai was doing the opposite kind of work, all in the name of restoration.

"(Back then) the fish heads — what I call the fisheries folks — we stood on the banks, and we looked at the stream," Nicolai, a Yakama Nation habitat biologist, told Oregon Public Broadcasting. "If we saw a big log jam, we thought, 'Oh, that's a barrier to fish. We want the stream to flow.'"

At the time, logs were removed in an effort to simplify the habitat. However, it soon became clear that wood provided vital "complexity," creating sheltered pockets for salmon and bull trout to spawn and supporting algae that feed aquatic insects. Logs also slow water, spread it across floodplains, and allow it to soak into the groundwater. That water is then slowly released back into streams, helping keep them flowing and cooler during hot, dry periods.

The consequences of removing this "critical part of the system" (in addition to overgrazing, railroad construction, and splash dam logging) were made all too clear over the years as the rivers dried up and wildlife populations declined.

"We're trying to learn from our mistakes and find a better way to manage," said Phil Rigdon, director of the Yakama Nation Department of Natural Resources.

That's why Nicolai is now helping lead a project for the Yakama Nation aimed at rebuilding river complexity by returning logs to their rightful place. Many of these streams are now unreachable by road, which is why helicopters are used. Logs are flown from staging areas and carefully placed at precise drop locations marked with pink and blue flagging tape.

The wood comes from forest-thinning projects led by The Nature Conservancy and includes species such as Douglas fir, grand fir, and cedar. Although some of the timber could have been sold, it is instead being used as river infrastructure.

For tribal leaders, the work carries even deeper meaning. During the helicopter flights, they gathered along the Little Naches River for a ceremony and prayer.

"It was very simple: to bring what was rightfully part of this land back to us," said former tribal chairman Jerry Meninick.

The aftermath of the original restoration project illustrates how human concepts, such as the belief in the superiority of "cleanliness," can be limited and sometimes cause more harm than good. The miracle of nature, however, is that when left to her own devices, she can heal herself.

Stop forgetting people's names by using the simple 'SUAVE method'

We're all bad with names. Here's the easy way to get better.

A man and a woman shaking hands.

Do you think you're bad at remembering names? If so, you’re not alone. In a 2022 poll, 58% of Americans say they struggle to remember the names of people they’ve recently met at least half of the time. Only 7% said they “never” forget the names of someone they recently met.

In a world where most people are bad at remembering names, those who are good at it are going to make quite the impression at their next neighborhood party or professional networking event.

How to get better at remembering names

According to Jim Kwik, the key to remembering people’s names is as easy as recalling the acronym SUAVE. Just think of it this way: everyone will think you’re SUAVE if you remember their name smoothly. Kwik is the world's number one brain coach and the author of Limitless: Upgrade your brain, learn anything faster, and unlock your exceptional life. He says the key is to focus on the person you just met. “A lot of people aren't forgetting the name, they're just not paying attention. The art of memory is the art of attention,” Kwik told podcaster Mel Robbins.

He shared the SUAVE method on a recent episode of the Mel Robbins Podcast.

@melrobbins
"When someone introduces themselves to you, do you usually forget their name 5 seconds later? It happens to me ALL the time. But not anymore after sitting down with @Jim Kwik, renowned brain coach, on tonight’s episode of the #melrobbinspodcast 👇 🎧 “Super Brain: 10 Things to Eat, Think, & Do to Improve Your Memory and Learn Faster” 🔗 in bio The #MelRobbinsPodcast is available in 194 countries, wherever you listen to podcasts. Search “mel robbins podcast” on YouTube to find all episodes. #melrobbins #changeyourlife #mindset #createabetterlife #takecontrol #motivation #brainpower #learnfaster #learnmore #improveyourmemory #brainhealth #podcast #podcastepisode"

Say

“Say the name right away when somebody gives you their name, greet them back using their name cause it means you get through it twice.” Kwik sid.

THEM: “Hello, my name is Sheryl.”

YOU: “Nice to meet you, Sheryl.”

Use

“You use the name, but you don't abuse the name,” Kwik continues. There is a fine line between repeating someone’s name so that it sounds natural and using it over and over so that you sound inauthentic and, perhaps, manipulative. Some suggest that in an interaction, such as a sales call, you use their name around three times to strike the right balance.

names, meeting people, introduction, handshake, hello A man and a woman shaking hands.via Canva/Photos

Ask

“This works really well for people who have unusual names or names you haven't heard of before,” Kwik said.

THEM: “Hello, my name is Khadesia.”

YOU: “Beautiful name. Just to get it right, did you say, Khadesia?”

Then, bonus points:

YOU: “Does Khadesia have a special meaning?”

Visualize

“You meet someone for the first time, and their name is Mary. Imagine, for a split second, that she's carrying two lambs under her arms. Mary had a little lamb,” Kwik said.

To further explain the concept:

Lara: Think of Lara Croft, Tomb Raider.

Tom: Think of a turkey, as in Tom Turkey.

Malcolm: Think of the TV show Malcolm in the Middle.

By making an extra connection between the person and another concept that you’re familiar with, it’ll make you more likely to remember the name. Think of it as a mental picture that connects the person and concept.

End

“End the conversation saying goodbye, using their name,” Kwik said.

YOU: "It was a pleasure speaking with you, Lara."

Ultimately, in a world where most people aren’t very good with names, remembering someone's at a party or networking event will make you stand above the crowd. Even more importantly, it shows the other person that you genuinely care, and that’s the best type of first impression you can hope to make on anyone.

Dry cleaner explains how corduroy is made and it has a surprisingly deep history

Corduroy originated in Ancient Egypt?!?

Corduroy has a surprisingly interesting story.

Considering how popular it was in the 1970s, one might assume that corduroy was invented in the mid-20th century. But that's not even close to true. In fact, the roots of corduroy go all the way back to Ancient Egypt, and the fascinating history of the famously ribbed fabric is surprisingly interesting.

Dry cleaner and stain-removal guru Zachary Pozniak shared some fun facts about corduroy in a video that has over a million views. (Who knew corduroy would pique so many people's interests?) What is corduroy? Where, when, and by whom was it created? Where does the word "corduroy" come from?

- YouTube www.youtube.com

Pozniak says that corduroy was popularized in the 18th century, but dates back to Ancient Egyptian times. According to The Rake, the fabric originated in the Ancient Egyptian city of Al-Fustan in the form of fustian, a heavy cloth woven out of linen and cotton. Outer vestments worn by Catholic priests were made of fustian for a time, and Italian and Spanish merchants brought it to Europe in medieval times. While Henry VIII owned many fustian garments, it was worn by working men as well.

That brings us to the 18th century, when modern-day corduroy became what Pozniak calls, "the working man's armor."

"Miners, factory workers, and builders wore it because it was durable, warm, and could really take a beating," Pozniak says. The reason corduroy is so durable is that there are extra sets of fiber woven into the base fabric, forming its signature vertical ridges called wales. "These wales are similar to velvet in that the fibers stick straight up and create that super luscious effect," Pozniask says. No wonder corduroy feels kind of velvety when you run your fingers across it.

As far as where the word "corduroy" comes from, Pozniak says a lot of people think it comes from the French corde du roi, meaning "cloth of kings," but it doesn't. It comes from a combination of "cord" meaning rope, and "duroy," a thick fabric made in England.

Judging by the comments on Pozniak's video, people love their corduroy and appreciate learning more about it:

"I am delighted. I am wearing my corduroy pants right now because it’s a chilly day in December. Thank you so much for celebrating this simple workmen clothing!"

"I love corduroy too. Corduroy trousers feel fantastic, it's weighted and soft. And keep you warm."

"It's one of my faves too! I always viewed it as a type of velvet, because it's called a 'corded velvet' in my language."

"I love corduroy to add texture and interest to a monochrome outfit. It looks so stylish when mixed with other textures in the same color!

"I love corduroy especially as pants and tote bags, really effortless chic."

"I looooove corduroy and hadn’t been able to find good ones since I was a kid since it went out of the cycle. It’s fun that it’s back in the fashion rotation! And hopefully made well and to last!"

According to Vogue, corduroy made a comeback in the fall of 2025. "Beloved for its heavyweight, durable fabric, the style staple promises to fight the chill on even the coldest of days. And lately, we’ve seen corduroy make the switch from country to cool…" the fashion magazine wrote. The fabric has been seen on celebrities and runways, and Vogue called corduroy pants "the ultimate staple to sport this season."

— (@)

So if you miss the swish-swish of your childhood corduroys, you can relive it in style as a full-fledged grown-up. Glamour Magazine suggests styling corduroy with baggy or preppy outfits, by layering textures, by choosing "rainbow bright" colors, and by wearing corduroy pieces in a set or corduroy pants with a classic striped sweater to keep it modern and chic.

Or, you know, just do your own thing. Corduroy has proven itself a classic, so wear it however it makes you happy.
