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.

Researchers dumped tons of coffee waste into a forest. This is what it looks like now.

30 dump truck loads and two years later, the forest looks totally different.

assets.rebelmouse.io

One of the biggest problems with coffee production is that it generates an incredible amount of waste. Once coffee beans are separated from cherries, about 45% of the entire biomass is discarded.

So for every pound of roasted coffee we enjoy, an equivalent amount of coffee pulp is discarded into massive landfills across the globe. That means that approximately 10 million tons of coffee pulp is discarded into the environment every year.


When disposed of improperly, the waste can cause serious damage soil and water sources.

However, a new study published in the British Ecological Society journal Ecological Solutions and Evidence has found that coffee pulp isn't just a nuisance to be discarded. It can have an incredibly positive impact on regrowing deforested areas of the planet.

via British Ecological Society

In 2018, researchers from ETH-Zurich and the University of Hawaii spread 30 dump trucks worth of coffee pulp over a roughly 100' x 130' area of degraded land in Costa Rica. The experiment took place on a former coffee farm that underwent rapid deforestation in the 1950s.

The coffee pulp was spread three-feet thick over the entire area.

Another plot of land near the coffee pulp dump was left alone to act as a control for the experiment.

"The results were dramatic." Dr. Rebecca Cole, lead author of the study, said. "The area treated with a thick layer of coffee pulp turned into a small forest in only two years while the control plot remained dominated by non-native pasture grasses."

In just two years, the area treated with coffee pulp had an 80% canopy cover, compared to just 20% of the control area. So, the coffee-pulp-treated area grew four times more rapidly. Like a jolt of caffeine, it reinvigorated biological activity in the area.

The canopy was also four times taller than that of the control.

The coffee-treated area also eliminated an invasive species of grass that took over the land and prevented forest succession. Its elimination allowed for other native species to take over and recolonize the area.

"This case study suggests that agricultural by-products can be used to speed up forest recovery on degraded tropical lands. In situations where processing these by-products incurs a cost to agricultural industries, using them for restoration to meet global reforestation objectives can represent a 'win-win' scenario," Dr. Cole said.

If the results are repeatable it's a win-win for coffee drinkers and the environment.

Researchers believe that coffee treatments can be a cost-effective way to reforest degraded land. They may also work to reverse the effects of climate change by supporting the growth of forests across the globe.

The 2016 Paris Agreement made reforestation an important part of the fight against climate change. The agreement incentivizes developing countries to reduce deforestation and forest degradation, promote forest conservation and sustainable management, and enhance forest carbon stocks in developing countries.

"We hope our study is a jumping off point for other researchers and industries to take a look at how they might make their production more efficient by creating links to the global restoration movement," Dr. Cole said.

People who chose to be child-free are just as happy at 70 as those with kids, study finds

What about all the regret they were supposed to feel?

via Jens Lindner/Unsplash

A woman looking content with her child-free life.

Every couple that has ever considered being child-free has had to deal with people who have children telling them they will regret their decision. They're often told that they’ll be lonely when they get older and never understand the joy and fulfillment of having a child.

Even though there is so much pressure for couples to have kids, more and more people are deciding to live child-free lives. A recent study found that 47% of adults under 50 without kids say they're unlikely to have them — up 10 percentage points from 2018.

There are many different reasons why people don’t want to have kids, whether it’s affordability, the state of the world and the environment, or they just don’t feel like it. The child-free movement gets even stronger as people get younger.

Sixty-seven percent of young women and 50% of young men say they just don’t want children. So, are all of these people setting themselves up for a lifetime of regret because they choose not to have kids? A recent study out of Michigan says no, they probably won’t.

The Institute for Public Policy and Social Research at Michigan State University studied 1,000 Michiganders, asking whether they have or want children. The study separated those who wish to be child-free from those who want children but can’t have them.

The study found that by the time people reach the age of 70, people who have children and those who decided not to are just as satisfied with their lives.

“Childfree people, especially women, are often told they’ll be dissatisfied with life or regret their decision later,” Jennifer Watling Neal, one of the study’s authors, told PsyPost. “In this study, we compared how much adults age 70 and older said they’d want to change something about their life — in other words, whether they had any regrets about how their life had gone. We didn’t see any difference between child-free people and parents. This suggests that child-free people are similar to others in terms of life satisfaction and often don’t regret their decision later.”

The researchers found that child-free people may be happier than those with kids.“In fact, older parents were slightly more likely to want to change something about their life,” Neal said in a statement.

The study was conducted on 1,000 people; times change and everyone’s experience is different, so there’s no telling who will or will not have regrets about their decision to have children. But the study should bring some peace of mind to those who are tired of hearing that they may regret their choice to be child-free, whether from friends, family or the little voice in their heads.

The discussion also raises a deeper question: How do we create a society where people are excited about having children? What changes could be made to make it affordable for people to have families? How can we create a brighter future so that parents can feel confident that the children born today will be able to thrive as adults?

Naming twins is an art. Here are some twin names people say are the best they've ever heard.

With twins, all the regular pressures of having a baby are doubled, including choosing a name.

Are you in favor of rhyming twin names? Or is it too cutesy?

Having twins means double the fun, and double the pressure. It’s a fairly known rule to name twins in a way that honors their unique bond, but that can lead to overly cutesy pairings that feel more appropriate for nursery rhyme characters than actual people. Plus, it’s equally important for the names to acknowledge each twin’s individuality. Again, these are people—not a matching set of dolls. Finding the twin baby name balance is easier said than done, for sure.

Luckily, there are several ways to do this. Names can be linked by style, sound or meaning, according to the baby name website Nameberry. For example, two names that share a classic style would be Elizabeth and Edward, whereas Ione and Lionel share a similar rhythm. And Frederica and Milo seem to share nothing in common, but both mean “peaceful.”

Over on the /NameNerds subreddit, one person asked folks to share their favorite twin name pairings, and the answers did not disappoint.

One person wrote “Honestly, for me it’s hard to beat the Rugrats combo of Phillip and Lillian (Phil and Lil) 💕”

A few parents who gave their twin’s names that didn’t inherently rhyme until nicknames got involved:

"It's the perfect way! Christmas cards can be signed cutely with matching names, but when they act out you can still use their full name without getting tripped up.😂"

"The parents of a good friend of mine did this: her name is Allison and her sister is Callie. Their names don’t match on the surface, but they were Alli and Callie at home."

“Alice and Celia, because they’re anagrams! Sound super different but have a not-so-obvious implicit connection.”

This incited an avalanche of other anagram ideas: Aidan and Nadia, Lucas and Claus, Liam and Mila, Noel and Leon, Ira and Ria, Amy and May, Ira and Ari, Cole and Cleo…even Alice, Celia, and Lacie for triplets.

Others remembered name pairs that managed to sound lovely together without going into cutesy territory.

“I know twin toddler boys named Charlie and Archie and they go so well together,” one person commented.

Another wrote, “Tamia and Aziza. I love how they follow the same sound pattern with the syllable endings (-uh, -ee, -uh) without being obnoxiously matchy matchy.”

Still another said, “Lucy and Logan, fraternal girl/boy twins. I think the names sound so nice together, and definitely have the same 'vibe' and even though they have the same first letter they aren't too matchy-matchy.”

Other honorable mentions included: Colton and Calista, Caitlin and Carson, Amaya and Ameera, Alora and Luella, River and Rosie, and Eleanor and Elias.

One person cast a vote for shared style names, saying, “If I had twins, I would honestly just pick two different names that I like separately. I tend to like classic names, so I’d probably pick Daniel and Benjamin for boys. For girls my two favorites right now are Valerie and Tessa. I think Val and Tess would be cute together!”

Overall though, it seems that most folks were fans of names that focused on shared meaning over shared sound. Even better if there’s a literary or movie reference thrown in there.

“My mom works in insurance, so I asked her. She’s seen a lot of unique ones, but the only twins she remembers are Gwenivere [sic] and Lancelot... bonus points... little brother was Merlin,” one person recalled.

Another shared, “If I had twin girls, I would name them Ada and Hedy for Ada Lovelace and Hedy Lamarr, both very early computer/tech pioneers. Not that I’m that into tech, I just thought it was a brilliant combination.”

Other great ones: Susan and Sharon (think the original “Parent Trap”), Clementine and Cara (types of oranges), Esme and Etienne (French descent), Luna and Stella (moon and stars), Dawn and Eve, plus various plant pairings like Lily and Fern, Heather and Holly, and Juniper and Laurel.

Perhaps the cleverest name pairing goes to “Aubrey and Zoe,” since…wait for it… “they’re A to Z.”

It’s easy to see how naming twins really is a cool opportunity for parents to get creative and intentional with their baby naming. It might be a challenge, sure, but the potential reward is having the most iconic set of twins ever. Totally worth it!

Woman sparks dialogue after saying she doesn't take advice from men no matter how successful

"I tend to take their advice with a grain of salt," says Paige Connell.

Woman says she doesn't take advice from men.

Being a woman comes with certain expectations, no matter where in the world you live. Becoming a mother adds another layer to those expectations, with traditional society often not considering the impact on the woman experiencing that shift. For instance, many women work outside of the home and are still expected to be the one who figures out which childcare center would be best.

Women are also often expected to put their careers on hold to stay at home if it's decided that outside childcare isn't feasible. Sure, some dads may do the heavy lifting in this area, but that's not a societally expected thing. Because these things are typically expected of women, men don't generally have to consider many of the logistics of children if they're partnered with a woman.

Paige Connell sparked a conversation when she shared on social media that she doesn't take advice from men, even if it's their job. On the surface that sounds harsh, even though she clarifies that she considers the advice but takes it with a big grain of salt, and her reasoning involves the invisible labor aspect.

"I do not tend to take a lot of advice from men, even the most successful men. And I mean advice in the form of self-help books, podcasts from successful men or just men in general. I tend to take their advice with a grain of salt because I do not think it is applicable to women and mothers in particular," Connell share before revealing her reasoning.

In the video she shares that she was recently listening to "The Diary of a CEO" podcast where the man talked about all the risks he took, including moving from Connecticut where his young child and ex-girlfriend live to New York. Connell pointed out through the entire episode detailing his risks and upward mobility, he never mentioned his child, which caused her to surmise that it was because childcare concerns weren't a part of his journey.


@sheisapaigeturner I do not often take advice from men, even the most successful of men, because the common thread is usually that they were able to become successful, because there was a woman standing beside them, or behind them, supporting them. Without acknowledging this, the advice means very little because women often don’t have men standing besides them, or behind them to support them. #caseyneistat #diaryofaceo #millennialmom #workingmom #wfhmom #corporatemom #successfulwomen ♬ original sound - Paige


She continued explaining how the burden of childcare tends to fall on women, working and nonworking, allowing the male parent to be free to corporate climb uninhibited by the worry. Connell shares that she prefers to listen to professionally successful moms because they share the help needed with childcare and how they navigated these spaces being the default parent. Others agreed to much of what she was saying.

"I came to a similar conclusion…I have read quite a few books of men going on their 'hero’s journey' where they did all these extravagant endeavors and eventually found success or enlightenment. But nothing about how a mother deep in the trenches of child raising is the [true] hero’s journey. Motherhood can chew you up and spit you out. A mother dies a million deaths and finds strength to continue to show up for her child day and night. Motherhood changes and refines us. No mother goes unchanged after motherhood. It is late nights and isolation. The flames of motherhood, the true hero’s journey," one person revealed, describing her own experience of realization.

"I love that you talk about it. Also all the so called geniuses, poets, writers, great personalities were able to accomplish all they did because their wives babysat their 8 kids at that time," someone else sighed in frustration.

"Couldn’t agree more. It’s the equivalent of men being able to work late, work weekends, put in the face time, to get ahead - whilst someone else is looking after their children," another wrote.

"I remember reading one comment in the daily routine of a successful writer. He had four kids and yet he could write for 6 hours daily during the day. Never once mentions his household manager, cook, cleaner, nanny—his wife," a commenter pointed out.

What do you think? Should more women be talking about this reality when it comes to the success of their male partners?

15-year-old surprises his sister with a wedding dance and there's not a dry eye anywhere

The song starts with a recording of them singing together as children.

Avery Albrecht/TikTok

The beautiful bond of brother and sister

Weddings are often catalysts for happy tears, but sometimes an extra special moment or gesture pushes it into "everybody grab a tissue" territory.

This video is one of those. Don't say we didn't warn ya.

Avery Albrecht shared a clip from her wedding reception in which her baby brother asked her for a dance. But Albrecht had no idea what kind of surprise the 15-year-old and her parents had in store for her. As the music begins, we hear children's voices singing—the two of them singing Phil Collins' "You'll Be in My Heart" together as children. And then the real song begins, with the bride and her brother—along with everyone watching—in a puddle.

Watch all the way to the end:

"There wasn't a dry eye in the house," Albrecht shared. There doesn't appear to be a dry eye on the internet, either.

"Stop it!! It’s 4 am in Sydney, and I'm a 43-year-old man sobbing while hiding under a blanket with my wife and 2 kids on the same bed, 😭" shared one person. "Family is the most important precious thing in the world!! ❤️"

"I went from cracking up about a stupid Hello Kitty video to sobbing in under three minutes. That must be so confusing to my central nervous system," shared another.

"I have to stop watching these things at work… people are thinking I am depressed, 😂" wrote another.

Some people shared how much it reminded them of their close sibling relationships:

"One of the most beautiful things I’ve seen. And being a much older big sister of littles (not little anymore by a long shot), I know the exact place this came from."

"I don’t know if she’ll read this but sweetheart you are so lucky! Please give your baby brother a hug for me. I lost my little brother 19 years ago this past June while I was pregnant with my first born son. I named him after him. And miss him so very much. 😢❤️"

"My little brother had a severe case of cerebral palsy and Down syndrome. He’s gone, but as I am watching this video, I can’t stop wondering what my life would be if he was healthy and still around… same about my older sister, who had also passed away. Crying my heart out now."

"Awwwwwwwe! The sweetest! You can tell how close you both are! Me and my sister are 12 years apart and she got married when I was 12 and she moved out and I had THE HARDEST time and cried almost everyday for a month!! ! I still would go over to her house and spend the night all the time… and then when she had children I became the built in babysitter for my nieces and nephew (also my fave ppl on the planet) She’s always was and still my very best friend. ♥️♥️"

Here's to the beautiful bond siblings can share, the families that nurture those bonds and this sweet brother-sister pair who gave us all the cleansing cry we needed.
