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.

man sweating and drinking a sports drink

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.

34 broken bones, a mural, and Buddy the Elf—what these three things have in common
True

The Bank of America Chicago Marathon took place on Sunday, October 12th. Every runner who took on the enormous feat of 26.2 miles is truly an inspiration. We’re proud to share three outstanding stories about the power of community, giving back and crossing the finish line. Not only did they run an outstanding distance, but they each also gave back by fundraising for an organization that changes lives for the better.

Running a marathon is so much more than race day. It’s sticking to a schedule, getting enough rest, learning how to fuel your body for long distances, and—perhaps the most challenging of all—building mental resilience.



Meet Leanne: Running after 34 Bone Fractures

Leanne was only 12 years old when during her middle school cross country practice, she fractured her right tibia, the shin bone in her leg. This wasn’t Leanne’s first time breaking a bone—it was actually her 34th fracture. After many years of being overlooked as "clumsy," Leanne felt immense relief and recognition when a doctor diagnosed her with brittle bone disease, an incredibly rare condition.

Lurie Children’s provided a care plan for Leanne to build strength and start running again. And as of October 12th, Leanne ran her second Bank of America Chicago Marathon. She said in an interview, “I never thought I’d run again. But against the odds, here I am, training for my second Bank of America Chicago Marathon... all because of Lurie Children’s.”

Leanne’s impressive journey is a testament to the incredible research of Lurie Children’s, where she gives back by volunteering at the hospital and running on its behalf. Talk about being a true inspiration.


Meet Everett: Running to Inspire Through Art

Everett is an artist who creates beautiful murals around the city of Chicago. He uses his art as a tool for storytelling for community and connection.

In addition to being an artist, Everett is a runner. He ran the 2025 Bank of America Chicago Marathon on behalf of Peace Runners 773, a non-profit organization that strengthens the community of Chicago. In this video, we follow Everett on a run to visit some of his favorite murals. The run ends at Garfield Park, where Everett just finished a mural that he dedicated to the organization—symbolizing growth, strength and togetherness. Everett didn’t stop there.

While building his strength as a runner, Everett is strengthening his city of Chicago. Through his running and artwork, Everett has brought more awareness and resources to his community.

Meet Joseph: Running on Behalf of Special Olympics


Joseph ran the Chicago Marathon on behalf of Special Olympics, dedicating each mile to one of 26 friends with a developmental disability. The last 1.2 miles were extra special. It was for one of his closest friends, Matt.

In this video, Joseph runs to Matt’s house. For every mile of this training run, he tells us a heartwarming anecdote about Matt. They met at camp and soon, Matt will be a groomsman in Joseph’s wedding. The duo even sends a Christmas card every year—most notably dressing up as Buddy the Elf and sharing a bowl of spaghetti with maple syrup (spoiler: it doesn’t taste good).

As Joseph runs, he says, “Before we get to Matt, a quick note about why I’m running on behalf of Special Olympics. Matt and I love sports. And so do many of my other friends. Donations help provide year-round sports training and competition for more than 20,000 people with intellectual disabilities across Illinois.”

Joseph is the perfect example of inspiration. Not only did he run an entire marathon, but he also found inspiration in his friends who love sports as much as he does.


Leanne, Everett and Joseph are three incredible people who have shown how much strength and perseverance it takes to run a marathon. Each runner is both empowering themselves and their community. Their dedication to the Bank of America Chicago Marathon shows that the people of Chicago have a passion for the city, their neighbors and their personal achievements.

Social skills expert shares 3 'magic phrases' that make you more likable

Sometimes, we need to overcommunicate how we feel about others.

vanessa van edwards, likability, communications skills, people skills, people laughing, good advice

Vanessa Van Edwards and people at a party.

A familiar misstep people make when trying to be likable is trying to impress others. They want to show they are funny, intelligent, and a great storyteller. They think being the life of the party is the road to likability. However, study after study shows that it’s a lot easier to be likable. All you have to do is show interest in others. To put it simply: If you like people, you will become more likable.

There’s a slight wrinkle in the notion that liking more people makes you more likable. Many people you like aren’t sure that you like them. The psychological phenomenon known as signal amplification bias says it best. We tend to overestimate how clearly we broadcast our feelings and intentions towards others. So, the person we like and who likes us may not know the feeling is mutual.


“We think our signals are obvious,” Vanessa Van Edwards told Steve Bartlett on the Diary of a CEO podcast. “If we like someone or if we’re having a good time, we think, ‘Oh, they for sure know it.’ They don’t.” Van Edwards is a communications expert and the author of Captivate: The Science of Succeeding with People.

To help people clearly communicate their feelings, Van Edwards suggests three “magic phrases” to show you care. Check out the video below.


Phrase 1: ‘I was just thinking of you’

“You think of a lot of people in your life all the time,” she said. “If you are thinking of someone and you can text them: ‘I was just thinking of you, how are you?’ I was just thinking of you, how’d that project go?’ was just thinking of you. It has been a while since we talked.’ You see a movie, you see a documentary, you see a matcha latte, you see a mug, you see a ceramic candle, and you’re like, ‘Ah, this made me think of you,’” Van Edwards said. “My text messages, my conversations, are full of actual moments where I was triggered to think of that person, actually,” she said, noting the importance of being genuine. “If you don’t think of someone, they’re not a person you need to have in your life.”


Phrase 2: ‘You’re always so …’

"So if you're with someone and you're impressed by them or they're interesting or they're funny, say, 'You always make me laugh. You’re always so interesting,’ or ‘You’re always so great in interviews.' Giving them a label that is a positive label is the best gift you can give someone, because it's fighting that signal amplification bias,” she continued.


Phrase 3: ‘Last time we talked, you mentioned …’

“We are so honored when we get brain space—that you remembered and you’re going to bring it up,” she said. “And you specifically bring up something that they lit up with, something they were like, ‘Ah, it was great, it was exciting, it was wonderful.’”


If studies show the more you like other people, the more likable you become, Van Edwards has the next logical step in becoming more likable. She makes it clear that, due to signal amplification bias, many people you like may not even know it. When we employ her three ways to be more likeable, though, we can let people know we like them without making them feel uncomfortable, thus establishing bond to build on.

Woman's frightening experience reminds everyone to lock hotel door.

Staying in a hotel feels safe. The doors are heavy and solid, the key cards don't have any identifying information on it (should you drop it), and most hotels will have security or at least front desk staff on site 24/7. However, it's still important for anyone traveling alone — especially women — to stay vigilant.

If you've ever stayed in a hotel, you know there's an additional lock you can latch as an added layer of protection. But sometimes weird things happen that make us rethink the comfort and security many of us take for granted.


TikTok user TayBeepBoop had a disturbing experience when a hotel front desk person attempted to enter her room while she was inside.

Some readers may find the story to be unsettling but it's a powerful reminder of exactly why situational awareness and caution are so important in today's world.

Tay, obviously frightened, uploaded clips from the event on her TikTok page, which has since garnered 6 million views. In the video, which is mostly the floor, door and bed, you can hear the man outside of her room knocking loudly asking to be let inside.

Tay asks the man repeatedly why he attempted to walk into her room using the hotel master key to which the man explains there's a problem with the woman's car. There's only one problem. Tay doesn't own a car and is only in town on business where she did not rent a car to get around town, relying only on other modes of transportation.

So, what the heck was the man doing at her door?

@taybeepboop

Replying to @dani klarić this was a really long and hard video to make, it was sort of traumatizing and I’m kind of freaked out about staying anywhere now and I dont leave my house much anymore tbh because I already was dealing with PTSD about my safety. I’m OKAY which is why im able to go through this footage now. I genuinely don’t want anything to do with this hotel, this is a PSA to stay safe and cautious. I don’t want people to go after this worker because I still don’t know what his intentions were and he could have just been trying to do his job

Tay was staying at the hotel alone and made sure to latch the additional lock on her hotel room door, which is the only thing that prevented this hotel staff member from getting into her room. Since the situation was so scary and went on for quite some time according to her video, she called friends on FaceTime to be a witness and help comfort her. Eventually the man leaves after repeated attempts to get the scared woman to open the door and Tay was able to get a male business partner to escort her safely to another hotel.

But the comments were filled with stories from women who have had similar experiences, and a few who had good safety tips.

"Please never say you’re alone in the hotel. I know you were shaken but please please don’t rely on front desk call the police. I’m so glad you’re safe"

"A car smoking in a garage and he takes 30 minutes to go upstairs, harass you, and speak to you in the phone BUT NOT CALL THE FIRE DEPARTMENT?!"

"As a former front desk agent. I’m almost 100% sure it’s illegal for hotel staff to go into a room knowing someone in the room. Please contact hotel"

Many people explained the danger of admitting you're alone upon check-in, while other commenters sympathized with the woman not thinking to call the police right away. With people traveling more as COVID-19 restrictions subside, there could be a greater chance for things like this happening so it's best to be prepared and err on the side of caution when traveling alone.

Women on the Road has several tips for hotel safety including making sure your door lock works, putting a chair under the handle of the door or buying a rubber door stop. The site also highlights the importance of locking your windows if they open and not opening the door for people you don't know.

- YouTube www.youtube.com

Another site geared towards safety is Solo Female Traveler and it recommends getting a floor higher in the hotel to make it more of a hassle for someone from outside to break in. It, too, reiterates the importance of locking the additional lock in the hotel room while you're inside.

While it's statistically unlikely you'll be a victim of a hotel robbery or whatever was happening with Tay, her experience is a reminder to research hotels and practice caution when traveling. In the end, Tay was safe, and has a thriving business sharing home tips and hacks for her audience of almost 2 million followers.

The rest of us should remember: always lock the deadbolt or chain.

A hair stylist trims a man's hair

While millennials and Gen Zer’s often get lumped together as the “young group,” they are certainly not the same. (Although it is kind of hard to tell with all the Y2K fashion floating around.)

But speaking as a millennial, we definitely have different approaches to life, many of which seem to come down to a sense of self-assurance. That goes for shopping, socializing, self-expression…and even going to the hair salon, apparently.


Alexis Rex (@rex.artistry), hairstylist and owner of Rex Artistry Salon in Maryland, gave a brilliant (and hilarious) demonstration of some key personality differences between her millennial clients and her Gen Z clients in a now-viral TikTok video.

subtle color, bold contrast, Olaplex, client behavior, social media, Maryland salon, pop culture, self expression Each generation has its own salon swag. Photo credit: Canva

First, Rex played her Millennial Customer.

Millennial Customer gently knocks on the door and immediately expresses her gratitude. “Hey girl! So good to see you! So excited!”

But at the same time, Millennial Customer wants in no way to be an inconvenience, so she immediately comes back with, “Where should I put my purse? It's okay, I'm just going to shove it in my own personal space so it's not in your way. At all."

Never one to demand attention, Millennial Customer wants a very subtle hair color change. Really, "it shouldn't even look like I got my hair done.” Not “super bold,” not “in your face.”

Then after flooding the hair stylist with compliments, Millennial Customer (ever wanting to be a good student) will ask a bunch of follow-up questions about how to maintain the style.

Then, Rex played her Gen Z Customer.

Gen Z Customer bolts through the door with a “Hey queen!” like a hurricane (who has time to knock?!) and is ready to plop her stuff down anywhere. Unlike her millennial counterpart, Gen Z Customer is perfectly fine to take up space unapologetically and even show up with hair that “hasn’t been brushed in a month.”

Gen Z Customer also knows exactly what she wants, and it’s anything but subtle. “I wanna do like in-your-face, bold contrast…I wanna look like a different f**king person. Let’s do it.”

The confidence…it’s…palpable.

Gen Z Customer has a different approach to complementing her hairstylist: “Oh my god! F**king Queen! You did that! God I love you.”

No further questions. Gen Z Customer already knows her brand of hair care products, and it’s “Olaplex. All Olaplex.”

Rex’s post quickly racked up 8.6 million views, generating literally tens of thousands of comments about how spot-on her imitations were.

Millennials in particular chimed in, many of whom couldn’t help but applaud its accuracy of depicting how millennials seem to constantly be apologizing for simply existing.

“I’m a millennial and once I missed the armhole for a sec when putting the cape on. I was convinced I had ruined the appointment,” wrote one person.

Another added, ‘I’m sorry for my hair. I’m sorry my hair takes so long. I’m sorry I had to move my head, omg I’m sorry. You offered me a drink? I will say yes. And then sorry.”

Many were also quick to applaud how Gen-Zers seemed to have no issues in this arena.

“Gen Z just fully owning the ability to take up space,” one person commented.

"As a millennial I love Gen Z so much. They’re so free to be themselves and so open,” wrote another.

While there may be differences between generations, we can all learn something from one another. And we all enjoy getting our hair did.

By the way, Rex didn’t leave out her Gen X or Boomer clients. She has plenty videos of her imitating them, as well as some nifty style predictions on her TikTok, found here.

Finally, someone explains why everyone needs subtitles when watching TV

No, you're probably not losing your hearing, and it's not just the actors.

Someone watching a video of Pete Davidson on their phone with subtitles at the bottom

It seems everyone needs subtitles nowadays in order to "hear" the television. This is something that has become more common over the past decade and it's caused people to question if their hearing is going bad or if perhaps actors have gotten lazy with enunciation.

So if you've been wondering if it's just you who needs subtitles in order to watch the latest marathon-worthy show, worry no more. Vox video producer Edward Vega interviewed dialogue editor Austin Olivia Kendrick to get to the bottom of why we can't seem to make out what the actors are saying anymore. It turns out it's technology's fault, and to get to how we got here, Vega and Kendrick took us back in time.


They first explained that way back when movies were first moving from silent film to spoken dialogue, actors had to enunciate and project loudly while speaking directly into a large microphone. If they spoke and moved like actors do today, it would sound almost as if someone were giving a drive-by soliloquy while circling the block. You'd only hear every other sentence or two.

But with today's technology, microphones are so small they can be strapped just about anywhere on an actor. This allows the actor to move about the set freely and speak at a normal volume without worrying that their words won't be picked up.

So then why can't we hear them? Turns out it's super complicated…and also not.

"A lot of people will ask, 'Why don't you just turn the dialogue up?' Like, 'Just turn it up.' And...if only it were that simple," Kendrick said before explaining, "If you have your dialogue that's going to be at the same volume as an explosion that immediately follows it, the explosion is not going to feel as big. You need that contrast in volume in order to give your ear a sense of scale."

Sure, you may be thinking, well that kinda explains it, but why do the music and other cinematic noises sound like they're beating on your eardrum while the dialogue sounds like the actors are whispering every line? That doesn't seem very balanced. There's more to it, and again, it falls back onto technology.

In the video, they explain how our televisions are too thin to hold large speakers facing in the correct direction, and until this video, it didn't dawn on me that the speakers to my television are indeed in the back. No wonder we can't hear. The actors are quite literally talking to our walls.

And there's more. Check out the full explanation in the video:

While it may be a confusing trend, there's a reason for it as Kendrick explains. And, some experts like the World Literacy Foundation note that watching television and movies with subtitles is especially beneficial for children. Studies have shown that simply putting on subtitles improves literacy for kids, and many actors support the practice. This is good news for those worried about the literacy crisis in America.

If subtitles help us "hear" and improve literacy, then I'm all for them.
