6 surprising, scientifically-backed ways to cool down quickly during a heat wave

Some of this advice may seem counterintuitive, but it may help you beat the heat.

Heat waves are hitting across the globe, and getting worse every year.

Phoenix is known for its scorching hot summers, with temperatures sitting at or above 100 degrees for much of the season. But even those seasoned by the Sonoran sun are struggling with nearly three weeks straight of high temps over 110 degrees, with overnight lows not dipping below 90 degrees for days on end.

(Having lived in the Valley of the Sun myself, I can attest that, yes, there is a significant difference between 100 and 110 degrees. At 100, you can still legitimately pull the "But it's a dry heat!" card. Over 110 is just miserable, not to mention dangerous.)

The Southwest isn't the only place experiencing record heat. The Lower Mississippi Valley and Florida are feeling it, and globally we're seeing parts of Europe and Asia breaking their own heat records as well.

With the globe predictably heating up due to climate change, there doesn't appear to be much end in sight for extra-oppressive heat waves. So aside from taking the necessary steps to curb climate change, we have to focus on how to cool ourselves down. There's a lot of conflicting advice out there, but here are some scientifically-backed ways to cool your body down quickly, especially if you don't have air conditioning or access to a pool or lake or river nearby.

1. Focus on cooling your hands and feet.

Everyone seems to have a different body part to focus on first for the quickest cool-down—your face, your neck, your wrists, etc.—but according to Professor Mike Tipton from the Extreme Environments Laboratory at the University of Portsmouth, the hands are where it's at.

"Your hands have a high surface area to mass area—they have lots of blood flowing in them when you’re hot. If your core temperature is hot, your body will send blood to the extremities in order to lose heat,” Tipton told Science Focus.

“Immersing your hands in cold water won’t feel as nice, but it’ll cool you much faster than even an ice bath! It’s so important to make a distinction between things that make you feel cooler and things that actually make you cooler.”

Cooling your feet works for the same reasons. We have lots of blood flow to our feet, so immersing them in cool water (not ice water, as that causes the blood vessels to constrict and reduce blood flow) can help cool you down quickly.

2. Try drinking hot liquids.

Yes, drinking cold drinks feels amazing when you're hot, but some experts say hot drinks can actually do more to help your body's natural cooling system work more efficiently. Ollie Jay, a researcher at the University of Ottawa’s School of Human Kinetics, explains why.

“What we found is that when you ingest a hot drink, you actually have a disproportionate increase in the amount that you sweat,” Jay told The Smithsonian. “Yes, the hot drink is hotter than your body temperature, so you are adding heat to the body, but the amount that you increase your sweating by—if that can all evaporate—more than compensates for the added heat to the body from the fluid.”

The one caveat is that the increased sweat has to have someplace to evaporate, so take humidity levels into consideration.

“On a very hot and humid day, if you’re wearing a lot of clothing, or if you’re having so much sweat that it starts to drip on the ground and doesn’t evaporate from the skin’s surface, then drinking a hot drink is a bad thing,” Jay added. “The hot drink still does add a little heat to the body, so if the sweat’s not going to assist in evaporation, go for a cold drink.”

3. Try some spicy foods, too.

Have you ever noticed that tropical places often have the spiciest foods? There are several theories for why that is, but one of them may be that spicy foods can actually help you stay cool.

Similarly to drinking hot beverages, eating spicy food makes you sweat, and sweat is the body's main cooling system. (Again, though, the effectiveness of this approach depends on your sweat being able to evaporate, so you may not benefit from your mouth burning if you're in a very hot and humid climate.)

4. Ditch the fan if it's extremely hot AND extremely dry or humid.

Fans can provide a nice breeze to help you cool down, but many public health agencies have recommended against using fans above 95 degrees F (35 degrees C).

However, Ollie Jay and 12 colleagues published a study in 2021 that found humidity levels make a difference in whether fans are actually effective for cooling in extremely high temperatures. Essentially, if temps are extreme and conditions are very dry or very humid, fans can make things worse. But as Science Alert points out, those conditions are not the norm in most places. When humidity is moderate, the temperature at which fans are effective can be higher than 95 degrees.

"[T]here are many locations on Earth where fan use could be safely recommended as an alternative to air conditioning all of the time despite air temperature exceeding the currently recommended threshold of 35 °C," the authors wrote.

(However, it is important to note that fans increase the risk of dehydration, so always make sure you're drinking plenty of fluids. And for older adults, fan use is not as effective as it is for younger people and can actually result in raising their body temperatures. So it's important that elderly folks and their caregivers follow heat guidance specifically for older adults.)

5. Just say no to the cold beer—or any alcoholic or caffeinated beverage

Cracking open a cold one may sound incredibly refreshing when you're sweltering, but alcohol and heat actually make poor bedfellows. That's because alcohol actually dehydrates you. Same goes for caffeine. And the fact that they are liquids is especially deceptive because they give you a false sense of hydration.

“If you’re drinking a lot of beer or alcoholic seltzer, it can feel like you’re taking in a lot of liquid and staying hydrated,” registered dietitian Julia Zumpano, RD, LD, tells the Cleveland Clinic. “But the alcohol offsets that because of the dehydrating factor.”

(If you're interested in the biological reason for alcohol being dehydrating, it reduces the release of vasopressin, an antidiuretic hormone (ADH) that works with your kidneys to keep your body fluids balanced. Alcohol is also a diuretic, which means it increases the fluid being pulled out of your body as urine.

Hydration is key to making it through a heat wave, so drink aplenty, but make it water. (And start hydrating early in the day. Keeping water near you at all times and continually drinking throughout the day will go a long way toward preventing heat illness.)

6. Try dabbing on some peppermint oil

I know, I know. Essential oils are quack cures and whatnot. But in this case, even though it doesn't drop your core temperature, there really is a scientific basis for topical peppermint oil making you temporarily feel cooler.

Menthol, the primary ingredient in peppermint oil, has been shown to induce a cooling sensation. If you've ever sucked on a menthol cough drop, you know the feeling. Peppermint oil creates a similar sensation on the skin, which can provide some psychological relief from the heat, even if it's not actually reducing your body temperature.

In one study, a menthol gel was found to have a longer cooling effect than either ice or a placebo gel on healthy males. But anecdotally, a few dabs of peppermint oil on my wrists, neck and inside my elbows provides some instant cooling relief on very hot days. When it's brutally hot outside, any bit of relief helps.

There are plenty more tips for beating the heat, from wearing light-colored clothing to avoiding strenuous activity, but the big takeaway from this list is helping our body's built-in cooling system work as well as it possibly can during extreme heat.

Ontario teen says he'll live in 'modular home' invention for a year to prove it can end homelessness

He's already invented a wooden car.

Ribal Zebian is going to test a house he designed by living in it for a year.

Ribal Zebian, a student from the city of London in Ontario, Canada, already made headlines last year when he built an electric car out of wood and earned a $120,000 scholarship from it. Now, he's in the news again for something a little different. Concerned with homelessness in his hometown, Zebian got to work creating a different kind of affordable housing made from fiberglass material. In fact, he’s so confident in his idea that the 18-year-old plans on living in it for a year to test it out himself.

Currently an engineering student at Western University, Zebian was concerned by both the rising population of the unhoused in his community and the rising cost of housing overall. With that in mind, he conjured up a blueprint for a modular home that would help address both problems.

Zebian’s version of a modular home would be made of fiberglass panels and thermoplastic polyethylene terephthalate (PET) foam. He chose those materials because he believes they can make a sturdy dwelling in a short amount of time—specifically in just a single day.

“With fiberglass you can make extravagant molds, and you can replicate those,” Zebian told CTV News. “It can be duplicated. And for our roofing system, we’re not using the traditional truss method. We’re using actually an insulated core PET foam that supports the structure and structural integrity of the roof.”

Zebian also believes these homes don’t have to be purely utilitarian—they can also offer attractive design and customizable features to make them personal and appealing.

“Essentially, what I’m trying to do is bring a home to the public that could be built in one day, is affordable, and still carries some architecturally striking features,” he said to the London Free Press. “We don’t want to be bringing a house to Canadians that is just boxy and that not much thought was put into it.”

Beginning in May 2026, Zebian is putting his modular home prototype to the test by living inside of a unit for a full year with the hope of working out any and all kinks before approaching manufacturers.

“We want to see if we can make it through all four seasons- summer, winter, spring, and fall,” said Zebian. “But that’s not the only thing. When you live in something that long and use it, you can notice every single mistake and error, and you can optimize for the best experience.”

While Zebian knows that his modular homes aren't a long-term solution to either the homeless or housing crisis, he believes they could provide an inexpensive option to help people get the shelter they need until certain policies are reformed so the unhoused can find affordable permanent dwellings.

German man picks apart the American habit of smiling at strangers in the most German way

Public transportation is a "smile-free zone."

A German man explains why smiling at strangers in public is weird in Germany

Americans have such an interesting reputation internationally, but one that seems to give our nationality away in Germany is our habit of smiling. That's not to say that Germans don't smile because of course they do! But they don't smile while passing strangers on the street or use it as a social nicety.

Some may consider the constant smiling that many Americans do as fake or disingenuous because it's not part of their cultural norms. Dominik, a German man who runs the YouTube channel Get Germanized, explains that Americans may be taken aback by the lack of smiling by German citizens in public settings.

In America, it's considered polite to smile when greeting people or even when entering a place of business while passing another customer. It's a social norm that signals to the other person that you're acknowledging them. Sometimes this can be followed by a good morning or a thank you if the person in question held the door. There are places in the country where this is not as prevalent, but even in large cities where everyone seems to be in a rush, smiling still seems to be an understood custom.

Cultures vary from state to state, so it's no surprise that German social niceties are different than those in the U.S., Dominik explains, "Smiling is social lubricant everywhere else. [In] Many cultures, especially English-speaking ones, smiling is a social default. You smile at strangers. You smile to soften social interactions. You smile even when you don't mean it. It's a universal, friendly, 'I'm harmless' gesture. In Germany, that's suspicious. People will think, 'Why is this person smiling at me?'"

He goes on to share that the German smile is rare because it is only used when they're familiar with the person and are genuinely happy or amused. According to Dominik, a German offering up smiles to random people could "feel fake, intrusive, or overly familiar." It can also be seen as nervousness, insecurity, or manipulation. Germans don't smile to soothe the discomfort of themselves or others. Instead, their faces remain neutral until they experience an emotion that would elicit change.

"German communication is built on honesty. Not just in words, their body language too. If they're tired, you'll see it. If they're annoyed, you'll feel it. If they're happy, they'll show it, but only when they actually are. No forced cheerfulness. No plastic service smile. No, 'How are you? Fine,' dance. It's refreshing once you get used to it. Like taking off a mask you didn't know was there," Dominik says.

The no-smiling cultural norm extends to the service industry in Germany. Customer service employees are there to solve the customer's problems, not to be entertaining. Dominik explains that Germans trust professionals who look focused while working. Even on public transportation, no smiling is going on between commuters; people mind their own business. They're not unfriendly, they're respecting your space." Dominik shares.

The German culture enthusiast assures viewers that Germans smile a lot, but it's reserved for friends, families, and cute puppies. They also smile at people they like, so it's not that Germans think Americans are strange for smiling; their cultural norms are just different.

Mom realizes she's been using the 'heavy' setting on her washer wrong for years—and fellow moms are shook

"Today years old when I realize why my blankets are sopping wet."

Stay-at-home mom Catrina shares shock at learning what the 'heavy' setting on her washer means.

Knocking out loads of laundry is a feeling of accomplishment that is unmatched. Depending on what needs to be washed, washing machines offer a variety of settings for the ideal clean. But even the most seasoned laundry pros can admit that they don't fully understand how to use them properly.

One stay-at-home mom shared her funny and relatable washing machine mistake. Catrina (@granolabarpan) got the shock of a lifetime when she realized that she had been using the "heavy" setting on her washer wrong for years.

"POV: today years old when it clicks why my blankets are sopping wet!!! I thought HEAVY meant heavy items being washed," she wrote in the video's overlay.

"Heavy on my machine means heavily soiled," she went on to add in the comments. "I thought it meant the stuff I was putting in the machine was heavy in weight/pounds."

Some moms are also realizing this for the first time. "Ok.. so I am 66 years old learning this???!! I always thought that heavy meant weight also😂," one person commented. Another person wrote, "Well I was today years old when I learned what heavy meant too…😂"

Others expressed confusion with so many settings, and reminiscing on simpler times. "Wait a minute. 😂. I think I need to for once go and read the manual because I have been wondering about all of the options," another user wrote. And another chimed in, "I want my old $250 3 options hot/warm/cold on/off washer back. It didn’t die it rusted out but took 25yrs to do it. I had 5 kids, plus my ex in-laws living with me."

Washing machine settings, explained

Struggling to understand the settings on your washing machine? You're not alone.

"Knowing these settings helps avoid common laundry mistakes, such as using the heavy cycle for heavy fabric weight instead of heavy soil, which can lead to ineffective cleaning or damage over time," Vanessa Ruiz, a professional organizer at Sparkly Maid San Antonio, tells Upworthy.

These are five washing machine settings and how they work:

1. Normal/Regular Cycle
Ruiz explains that this is your typical setting for day-to-day loads such as t-shirts, jeans, sheets, and underwear.

"These laundry loads are typically washed in warm water and the setting is rinsed with medium spin speeds through agitation in order to properly clean moderately soiled garments," she says. "This cycle is safe enough to wash a variety of different fabric content with a somewhat dirty load."

2. Delicate/Gentle Cycle
Ruiz notes that the delicate cycle is created specifically for delicate fabrics—lingerie, silk, lace, or embellished clothing—that may become damaged in a normal or regular wash.

"This cycle will use moderate spin speeds through gentle agitation to thoroughly dry clean and not damage clothes too easily," says Ruiz. "This is the preferred cycle when laundry items that require extra care or are labeled 'delicate' or 'hand wash' need to be washed."

3. Heavy Duty Cycle
The heavy duty cycle is specifically for heavily soiled items like work clothes, kitchen towels, and bedding.

"This setting uses higher water temperatures, longer wash times, and powerful agitation to remove stubborn dirt and grime. It’s perfect for those tough laundry jobs, but not recommended for delicate fabrics," explains Ruiz.

- YouTube www.youtube.com

4. Bulky/Bedding Cycle
This cycle is often confused with "heavy."

"This cycle accommodates larger, heavier items that absorb a lot of water, such as comforters, pillows, and sleeping bags," says Ruiz. "It uses more water, medium spin speeds, and longer wash times to thoroughly clean bulky items without causing damage or imbalance."

5. Quick Wash
In a rush? This is the perfect setting to use.

"It is an accelerated wash cycle designed for small loads of lightly soiled clothes, usually lasting 15 to 40 minutes," says Ruiz. "It’s great for when you need clean clothes fast and can save energy compared to longer cycles."

79-year-old man publicly sings Barry Manilow's 'Mandy' to his dental hygienist and nails it

"Barry Manilow will be proud."

An elderly man sings karaoke. Barry Manilow poses for a headshot.

Sometimes, people just want to sing. They imagine themselves belting out their favorite tunes to whomever will listen. But for many, anxiety overtakes their fantasy. The thought of messing up or sounding bad is just too terrifying, and they end up keeping their songs to themselves.

Luckily for a 79-year-old man named Colin in Barnsley in the UK, the opportunity to turn this fantasy into a reality presented itself. Singer/songwriter Ruth Lisgo had begun recording karaoke on the street, occasionally handing out a microphone to those who wanted to join in on harmonizing or singing a verse or two.

Colin first went viral after singing "Words" by the Bee Gees. Lisgo states on an Instagram post that "over one million have now viewed that video."

@ruthlisgomusic

Replying to @Sir Nick the Naughty I absolutely agree Nick. So often when I’m busking I come across people who have so many stories to tell and often in life it just takes a few minutes to really make a difference with someone by listening ❤️ 🙏 Colin has many stories I’m sure #words #beegees #busking #takethetime

Well, Colin has returned a few times, most recently to belt out "Mandy" by Barry Manilow. An added bonus is that he dedicated his rendition to none other than his dental hygienist.

In a chyron over the clip, Lisgo explains, "This man asked if he could sing on my mic. He told me he only sang karaoke at home when he was younger, but always loved singing and music. But he was afraid of forgetting words and being on a stage. He came back today to sing this for his dental hygienist who had seen the video of him singing 'Words' by the Bee Gees, and she requested him to sing this ahead of her going to a Barry Manilow concert in 2026."

Clad in a warm coat and beanie, Colin grasps the microphone. His hands seem to shiver in the cold, but what comes out of his voice is pure warmth and perfection. He begins, "I'm standing on the edge of time. I've walked away when love was mine." For a moment, he blanks on the following lyric, "Caught up in a world of uphill climbing, the tears are in my mind and nothing is rhyming." But Lisgo steps in to help him find his way.

Now for the chorus and a key change: "Oh Mandy! Well, you came and you gave without taking, but I sent you away. Oh Mandy! Well, you kissed me and stopped me from shaking. And I need you today. Oh Mandy!"

The clip jump cuts to both Colin and Lisgo caught up in the moment. You can clearly feel the pride, smiles, and applause as Lisgo flips the camera to reveal a small crowd has formed. Lisgo asks commenters under her Instagram post to please share where they live so Colin can feel love from all over the world.

Over 5,500 people (and counting) did just that. Chiming in from Canada to Turkey to Finland to Sweden, compliments poured in by the hour. "Wonderful moment for him and for us," one Instagrammer writes.

Another addresses their comment directly to Lisgo, praising her for bringing so much joy. "I don't know you, but I actually watched your reaction to him singing and it was beautiful. I could see the heart and kindness in your face." Lisgo replies sharing how moved she was, writing, "I was brought to tears and I was feeling so much in this moment. It really was special and magic - thank you!"

Another commenter shares what so many of us believe: "Barry Manilow will be proud."

Real people say this post-hangout question helps keep friendships alive

"It's such a simple and effective way to show love..."

People think this post-hangout question can be a friendship game-changer.

It's not always easy to maintain close friendships as an adult. Everyone's busy and to some degree exhausted, and free time is scarce. So how do we maximize our friend time? And how do we reach out without looking too pushy? A regular person offered a suggestion: asking one thoughtful post-hangout question that's made their friendships "so much stronger."

It's pretty simple: "When's the next time I'll see you?"

Here's their logic: "You're showing enthusiasm for seeing your friend again, reassuring them you had a good time, and planning the next time you'll see each other all in one go," they wrote on Reddit. "Obviously this requires the friend to reciprocate, but it's such a simple and effective way to show love that has had consistent, lasting effects on my friendships. I don't typically say this to new friends; it's for people that I'm confident I want consistently in my life."

- YouTube www.youtube.com

Their trending post earned hundreds of replies, as people weighed in with their perspectives.

One person appeared to echo the OP's sentiment, talking about the importance of having a "chooser" in friendships—someone who will take on the role of making plans. "'Be a chooser' is the best advice I ever received," they wrote. "People want to hang out, but very few want to make the decision to hang out and organize it. Be the chooser…people will follow."

In reply, someone added, "I'm the planner and the calendar friend. For a long time, I took it so personal that no one else really planned things. But actually, people appreciate this. If they didn't, they'd make excuses to not hang out or would just say no instead of enthusiastically agree."

Here are more interesting comments, including some with a different perspective:

"This works because it removes guesswork"

"I have a group of girlfriends from college that get together every month for brunch, and most of them are also in a book club with me. At the end of each hang, whether it's brunch or book club, we get our calendars out and plan the next one. Occasionally we skip a month if there's a ton of conflicts, and not every person makes every single hang, but they happen very regularly and have been happening regularly for about 2 1/2 years now. We're all late 30s-mid 40s with careers and (in their cases,) spouses and families. 10/10 everyone should do this!"

"It rules that this works for you! I have to say, if someone asks me this, unless we're super duper bestest friends I'm just gonna say, 'hopefully soon- let's talk!" and not much will change. Seeing friends is more of a time issue than a desire issue IMO. Even if we want to plan things, we're busy a lot."

"I see the usefulness of this, but also I think this would low-key give me a panic attack if I just got done hanging out with someone and they wanted to plan the next one. I'm fully prepared to believe this is a 'me' thing"

"Agree with you in spirit but phrasing it that way puts a lot of pressure on them to figure out a date in advance, and some people don't like to plan far in advance."

"Instead I usually go with something like 'what's our next thing?' Easier for another person to figure out what something is than when on the spot"

"I love this because it shows intention without being clingy. So many friendships fade just because no one makes the next step explicit. This feels simple, warm, and very human."

"If this isn't your speed, you can also text them the next day. This works well for anxious people because it also sends them an affirmation/aftercare if they are worried about the hangout."

"This works because it removes guesswork. Clear interest plus a next step keeps friendships from fading by accident."

- YouTube www.youtube.com

"Focus on the reception"

While some people felt the question could come off as pushy, the OP clarified their stance with a few key points: they don't ask it every time they see someone, particularly people they see often, and they always make sure to read the room. They continued, "You do NOT do this after an exhausting event, or with people who do not like planning. Sometimes it's a conversation opener; others it's a time to pull out the calendar. This works well for busy people who also like consistent quality time. If that is not you, that's okay."

While every friend dynamic is unique, it's natural to feel like you're constantly initiating hangout plans.

Friendship coach Danielle Jackson explored this idea in a 2021 YouTube video, explaining that there are three key things you can do if you feel like the "giver" in a relationship: give the other person the "opportunity to initiate," reframe how you view their contributions, and "focus on the reception" rather than the initiative. "At the end of the day," Jackson says, "it's less about who's asking and more about who's saying yes."
