People Are Being Warned Not to Drink Coffee in the Heat. I Asked Experts if That's an Exaggeration

The summer has just begun, and many areas across the US are already experiencing sweltering temperatures. In response, NWS Las Vegas, the National Weather Service covering southern Nevada, northwestern Arizona, and southeastern California, posted an extreme heat warning graphic on X, cautioning residents not to drink caffeine because it speeds up dehydration, contributing to heat stroke and exhaustion. NWS Las Vegas's graphic soon made headlines, in which Americans were "warned not to drink cof

13 Best French Presses (2025): Plastic, Glass, Stainless Steel, Travel

The French press is an unassuming piece of coffee-making equipment. It doesn’t require electricity, yet experts agree that it can brew a richer and more full-bodied cup of joe in comparison with its more technologically advanced peers. For example, natural oils that would otherwise be filtered out in a drip coffee maker remain fully intact, making the coffee aromatic and robust. The French press method of making coffee is straightforward, cost-effective, easy to do, and hard to mess up. The dev

Breville Luxe Brewer Review (2025): Good Drip, Real Cold Brew

The new Breville Luxe Brewer is designed for hot coffee. It makes excellent, subtle, hot drip coffee. But it also does something that almost no other fancy coffee maker on the market achieves.

Good News! Caffeine Might Help Your Cells Live Longer

As if we needed any other reason to drink coffee or tea, new research provides insight into how caffeine supports health and longevity. Researchers in London studying fission yeast—a single-celled organism similar to human cells—have revealed that caffeine impacts aging via an ancient cellular energy system. Their study, published yesterday in the journal Microbial Cell, bolsters previous research suggesting that caffeine reduces the risk of age-related diseases and carries important implicatio

Backyard Coffee and Jazz in Kyoto

One of the things I read about while getting ready for our vacation in Japan were these famous tiny businesses: bars or izakayas with four seats, narrow little bookstores or record shops in people’s houses or the bottom floors of small buildings, hyper-specialized or themed bars owned by one passionate guy. (There’s one that’s chock-full of Star Wars memorabilia, for example.) We got to visit a couple of such places, and saw many more from the street. I’m planning to write a longer, more themat

Is Green Tea Really That Good for You? The Health Benefits You May Be Missing

So many of us need that morning coffee to get us through our day. One estimate says that 85% of US adults enjoy up to two cups of coffee daily. That being said, not everyone loves the taste or the side effects of coffee. The caffeine jitters and the trouble sleeping can be stressful. Looking for an alternative that will give you the energy boost without as many side effects? Green tea is a popular and tasty and it also has three times less caffeine than coffee as well as additional health benefi

24 Best Flavors of AriZona's Iconic Iced Tea (2025)

The internet loves to wax poetic about the eternal virtue of Costco’s $1.50 hot-dog-and-soft drink special, but where’s the love for AriZona’s 99-cent tallboys? Aside from a brief gag in a 2016 episode of Atlanta, very little fanfare is given to this under-costed dynamo of flavor and refreshment. Thirsty folks from all socioeconomic strata instantly recognize the colorful 23.5-ounce cans in their local bodega, and most flavors can still be found for 99 cents (plus applicable taxes and deposit fe

6 Best Travel Mugs of 2025, Tested and Reviewed by WIRED Staffers

Honorable Mentions Photograph: KeepCup We've run through many travel mugs, and not all of them are winners. These are a few we like, just not as much as the ones above. KeepCup 12oz Coffee Cup for $28: This double-walled, insulated mug is meant to replicate (and replace) paper coffee shop cups. This is a solid option if you're looking for a glass cup (the rubber grip is plastic, though). That said, it’s not the best for preserving your coffee's temperature, and the lid is a tad wobbly.
