Eight Sleep's new smart bed tech promises to end night sweats and boost deep sleep — here's how
This upgrade is the first step in the company's new Women's Sleep Initiative, a long-term commitment to advancing the science, knowledge and solutions around women's specific sleep issues.
Between menopause, menstrual cycles, pregnancy and PCOS (Polycystic Ovary Syndrome), sleeping isn't always an easy feat for many women (yes, the gender sleep gap is real). And much of this boils down to hormone changes and body temperature dysregulation.
"Menopausal women using the Pod with temperature regulation experienced 55% fewer nighttime hot flashes on average"
"Women are more sensitive to nighttime temperature changes, especially during their cycle, pregnancy, and menopause," Dr. Nicole Moyes, Ph.D., Senior Director of Science and Clinical Research at Eight Sleep, explains.
This is where Eight Sleep's new Hot Flash mode comes into clutch.
Tracking sleep quality, body temperature and various other recovery metrics, Eight Sleep pods, which we think are some of the best smart beds on the market, already help many people get a handle on their sleep health and general wellness.
Now the Hot Flash mode will take even better care of women's sleep no matter their stage of life or where they are in their menstrual cycle.

'Women's bodies change dramatically over time, and as wearables become more popular, it's important to recognize that data is not enough when looking to solve the challenges that we encounter during sleep,' said Alexandra Zatarain, Co-Founder and VP of Brand & Marketing at Eight Sleep.
'We recognize that it's time to use technology to solve women's sleep challenges, and we are starting with hot flashes, one of the most common and disruptive symptoms of menopause,' she adds.
The Eight Sleep Hot Flash Mode is a first-of-its-kind technology providing quick cooling to counteract nighttime hot flashes as soon as they materialize.
Women suffering with temperature imbalances will know these flashes can come thick and fast, so this speedy cool-down feature, backed by extensive user research and clinical testing, promises to be a real game changer.
With Eight Sleep's Hot Flash mode, women can get rapid cooling to help them cool off and fall back asleep quickly
"Hot flashes, which affect 80% of menopausal women, can also significantly affect sleep," Dr. Moyes says.
"With Eight Sleep's Hot Flash mode, women can get rapid cooling to help them cool off and fall back asleep quickly vs. laying awake drenched in sweat."
But how exactly does it work? By simply tapping the Pod's embedded button (found on the side of the mattress cover), sleepers activate the Pod's water-based cooling system. Colder water spreads through the tubes lining the smart mattress cover, reducing the temperature of the bed surface.
The aim of the rapid-response cooling experience is to minimizes sleep disruption while restoring thermal comfort in real time for optimal recovery every night.

And it doesn't only benefit menopausal women. "Body temperature changes throughout the menstrual cycle, and so even the small 0.3-0.7C increase in body temp during the luteal phase can lead to more wake ups or discomfort, and so sleeping on a temperature-regulated cover, like the Eight Sleep Pod, can help regulate temperature and keep you sleeping through the night," Dr. Moyes explains.
10 minutes was all it took for 8 out of 10 women to feel relief from hot flashes
"We can support women's needs for cooler sleeping temperatures during the 3rd trimester by cooling the bed temperature," she adds.
Before launch, Eight Sleep invited women experiencing hot flashes to test this technology. The results spoke for themselves. After activating the Hot Flash Mode, 10 minutes was all it took for 8 out of 10 women to feel relief from hot flashes.
Dr. Moyes says a clinical study presented at the 2025 SLEEP conference found that menopausal women using the Pod with temperature regulation experienced 55% fewer nighttime hot flashes on average.
In the Eight Sleep app, you'll now be able to access Hot Flash Reports too, helping you track the frequency, timing and patterns of hot flashes throughout the night and from night to night. These insights empower more informed conversations with healthcare providers.
The Women's Sleep Initiative builds on Eight Sleep's mission to deliver higher-quality sleep, tailored to how real bodies sleep, recover and perform.
Alongside the launch of Hot Flash Mode, the first phase of the initiative includes major investment in women-focused sleep research (that means large-scale data collection from tens of thousands of women), development of adaptive Pod features for menstrual, reproductive and menopausal transitions, and collaborations with leading experts in reproductive health and sleep science.

Ozempic May Help Prevent This Medical Emergency, According To New Research
You've probably heard by now that Ozempic may do much more than *just* help you lose weight and manage your blood sugar. Along with lowering the risk of Alzheimer's disease, tamping down PCOS symptoms, and combating a slew of other serious health conditions, three new studies suggest that the medication could help prevent and treat stroke. It may seem like a random link, but doctors say it actually makes a lot of sense. We tapped two neurologists and a doctor who prescribes Ozempic for more details. Meet the experts: Clifford Segil, DO, is a neurologist at Providence Saint John's Health Center in Santa Monica, CA; Amit Sachdev, MD, is the medical director in the Department of Neurology at Michigan State University; Mir Ali, MD, is medical director of MemorialCare Surgical Weight Loss Center at Orange Coast Medical Center in Fountain Valley, CA What do the studies say? All three studies were recently presented at the Society of NeuroInterventional Surgery's annual meeting, and they have a common theme. The first was published in the Journal of NeuroInterventional Surgery. For the study, researchers analyzed data from a global database and a database from the University of Wisconsin, looking at more than 2 million people who had a stroke. Of those, nearly 44,000 were also on Ozempic. The researchers found that people who took Ozempic were less likely to die from stroke, and the differences were huge. In the global database, 5.26 percent of Ozempic users initially died from their strokes, compared to 21.6 percent of those who didn't take the medication. The University of Wisconsin group had similar results: 5.26 percent of Ozempic users died from stroke compared to 26.6 percent of those who didn't take the medication. The next study was also published in the Journal of NeuroInterventional Surgery. It looked at ER records for people who had a stroke and those who were likely using Ozempic. (The researchers looked at medical codes that usually suggest a patient is on Ozempic, but couldn't definitively say they were taking the medication.) The researchers found that people who likely used Ozempic had both a lower risk of stroke and a lower risk of dying from any cause compared to those who didn't take the medication. For the final study, researchers analyzed patient records from six months and 12 months after people had a brain hemorrhage, and a year and two years after having a stroke. The researchers discovered that people who used a GLP-1 receptor agonist medication like Ozempic had a lower risk of cognitive side effects, seizures, future brain bleeds, and death after a brain hemorrhage and stroke. Why might Ozempic help prevent or treat stroke? All of these studies found a link between people who took Ozempic and a lower risk of having stroke or serious complications from a stroke. But it's important to point out that they didn't prove taking Ozempic will have this effect. That said, there are a few reasons why Ozempic may have this impact. It could simply be tied to weight, says Amit Sachdev, MD, medical director in the Department of Neurology at Michigan State University. 'Obesity is a major risk factor for cardiovascular health,' he says. 'Reducing excess weight is expected to have a clear and positive impact on overall health, including cardiovascular health.' Clifford Segil, DO, a neurologist at Providence Saint John's Health Center in Santa Monica, CA, agrees. 'Lowering a person's weight lowers a person's fats circulating through their blood or their lipid level,' he explains. 'High lipid levels, or fats, circulating through your blood can cause clogged pipes in your brain or an ischemic stroke.' But Ozempic and other GLP-1 receptor agonists also help improve a range of health conditions that are linked with stroke, points out Mir Ali, MD, medical director of MemorialCare Surgical Weight Loss Center at Orange Coast Medical Center in Fountain Valley, CA. 'It's hard to say if this is due to improvement in blood sugar control, weight loss, or other health conditions,' he says. More ways to lower your risk of stroke Taking Ozempic isn't for everyone, and doctors stress that we're not quite there yet with actually recommending the medication to lower your risk of stroke. If you want to lower your risk of stroke, the Centers for Disease Control and Prevention (CDC) recommends taking these steps: Focus on your diet. That means eating plenty of fruits and vegetables, and minimizing foods high in saturated fats, trans fat, sodium, and cholesterol. Try to maintain a healthy weight. Being overweight or having obesity increases the risk of stroke, Dr. Ali points out. Move regularly. Getting at least 2.5 hours of moderate-intensity physical activity can help. Don't smoke. Smoking is a big risk factor for stroke. Limit . Men should have no more than two drinks a day, while women should have no more than one, per the CDC. However, doctors generally recommend having even less. Do your best to manage underlying health conditions. That includes cholesterol, diabetes, blood pressure, and heart disease—all of which are risk factors for stroke. Of course, if you have a family history of stroke or personal risk factors, it's important to talk to a healthcare professional. They can offer personalized guidance to help keep you healthy.

This Gen Zer dropped out of NYU at just 19 to launch his blockchain—now, his $1.3 billion company is backed by Mark Cuban and he never takes a day off
Being in the C-suite is a high-pressure job with long hours, responsibilities to the board, and intense scrutiny. But what is it like to be a top executive when you're off the clock? Fortune's series, The Good Life, shows how up-and-coming leaders spend their time and money outside of work. Today we meet Eric Chen, the CEO and cofounder of financial blockchain Injective Foundation. Hype around cryptocurrency has been growing for years, and Wall Street is now finally embracing it. Chen's company provides investors a secure platform to reinvent global markets; he says his layer 1 blockchain is one of the largest crypto networks ever built, leading the industry in user activity, transactions, and monetary volume. Since its 2018 inception, Injective has processed more than 2 billion on-chain transactions, with over 1.5 million wallets on the system. It has raised $56 million from major investors such as Binance, BitGo, Pantera, Jump—and even ex–Shark Tank billionaire investor Mark Cuban. 'The mission is simple: to create a truly free and fair financial system through decentralization,' Chen tells Fortune. 'It does so by giving every builder, financial institution, and user the tools they need to reinvent global markets in a fully transparent and permission-less manner.' Over the past seven years, Injective has grown to a $1.34 billion company—and at 26 years old, Chen is just getting started. More impressively, he launched the company at just 19 while enrolled in New York University. Chen was studying finance and mining Ethereum in his dorm room, all while interning at Innovating Capital on a hedge fund desk. The then-teenager was inspired to launch Injective after witnessing the inefficiencies of the traditional market, so he dropped out of NYU and started building his billion-dollar business. Injective has since made leaps in progress; Deutsche Telekom, T-Mobile's telecoms arm, joined as a validator, bringing Fortune 500–quality network infrastructure. Cboe Global Markets—the largest options exchange in America—also submitted a request to list the fund, signaling strong institutional interest and placing Injective among networks with potential U.S.-listed ETFs. Because of his business's massive growth, Chen says he can't remember a time when he was fully away from his work. The CEO's fun luxury gadgets—including a $2,900 mattress cover, Oura ring, and racing simulator—help keep him sane, he says, in the thick of his busy schedule. He never buys groceries, opting to eat out in New York City or DoorDash his food. Taking very few swanky vacations, he lives a globe-trotting lifestyle through his business, with trips to Seoul, London, Toronto, Abu Dhabi, and Singapore this year. The finances What's been the best investment you've ever made? My Eight Sleep mattress cover, around $2,900. It enables me to be maximally efficient with sleep and minimize chances of productivity drop-off due to poor sleep quality. And the worst? I wouldn't say there's been a single 'worst' investment so far. Every decision, whether it's worked out or not, has taught me something valuable and shaped how I think going forward. I try to approach everything with a learning mindset, which helps turn even the less successful bets into long-term upside. How do you commute to work? I live in New York, so my commute is usually a quick walk from home to the office. How much is in your wallet? Do you have any fun credit cards you'd recommend? Fiat [government tender, like the U.S. dollar] is dying so I actually never carry any cash! Do you invest in shares? I mainly only buy and hold crypto via apps on Injective. I dollar-cost-average into my favorite assets and use various programmable AI-driven bots to automate most trades, since I'm normally very caught up with work to follow the markets closely these days. The best approach is to learn by doing, while keeping risk low at the start. There are many great resources online including tutorials, videos, and forums that can help you build a strong foundation. Most platforms also offer paper trading, which allows you to practice with simulated money and no real financial risk. Use that experience to gain confidence before investing actual funds. Make sure you feel prepared to handle the ups and downs of the market before jumping in. What personal finance advice would you give your 20-year-old self? Invest more in Bitcoin. What's the one subscription you can't live without? My Oura ring subscription. It's great for tracking daily calories and sleep, which honestly is a godsend. Where's your go-to wristwatch from? I love my Apple watch. Simple yet effective. The necessities How do you get your daily coffee fix? Back when I first started Injective in college, I was running almost entirely on Red Bull. We even had a Red Bull fridge in our first office to keep a steady supply. These days I've made the switch to Celsius or double-espresso to keep me going. What about eating on the go? Like with my workouts, I try to be pretty disciplined about stepping away from my desk for lunch when I can. Most days, I'll eat in our communal office kitchen. It's a good break and gives me a chance to catch up with the team. That said, there are definitely days when things are nonstop and I end up eating at my desk or on the go. I used to order takeout a ton since I have no time to cook, but recently I've started to meal prep. So, usually I just eat that at my desk while catching up on news at the same time. Where do you buy groceries? This is going to sound horrible, but I am not sure I ever really buy groceries. I live off of meal prep and DoorDash most days. How often in a week do you dine out versus cook at home? About 90% of the time, I end up eating out between work meetings, dinners, or just taking advantage of being in New York. There's always something new to try, and so many great spots nearby. Any go-to restaurants or takeaways near you? One of my favorites right now is Barlume, a Mediterranean place near our office that I go to pretty regularly. Where do you shop for your work wardrobe? Comfort has always been my priority. My style has definitely changed since college—whose hasn't? Back then I'd just throw on whatever I got from conferences or hackathons. These days, I still keep it comfortable, but now I'll reach for something like Sporty & Rich. What would be a typical work outfit for you? I wouldn't say I have a set everyday wardrobe. Some days it's gym shorts, a polo, and flip-flops, especially if it's a more casual day. Other times, if I have an important meeting, I'll opt for a shirt and chinos. It really depends on what the day calls for. Are you the proud owner of any futuristic gadgets? I'm not sure if it counts as futuristic, but my guilty pleasure is definitely the racing simulator I have at home. It's the biggest gadget I own, and it does an insanely good job of simulating the real thing. The treats How do you unwind from the top job? If I have the time, I love playing tennis. It's one of the few things that really helps me unplug and reenergize. It's physically active but also mentally engaging, which makes it the perfect combination for me. Even just hitting for an hour clears my head and gives me a second wind. What's the best bonus treat you've bought yourself? After hosting a big Injective event in Belgium, I booked a few hours on a real race track with my friends. The simulator practice paid off. How do you treat yourself when you get a promotion? I usually don't buy myself anything physical as a reward, to be quite honest. Getting to go to a concert with my friends or checking out interesting performances in the city is the closest thing to a bonus reward I would say. Take us on holiday with you: What's next on your vacation list? My next vacation will actually be to Northern Macedonia to attend the wedding of one of our original Injective developers. It's a special full-circle moment, and I'm excited to celebrate with someone who's been part of the journey since the early days. Usually my 'vacations' are just work conferences around the world. This year alone, I will have been in Seoul, London, Toronto, Abu Dhabi, and Singapore for talks I am giving. How many days of annual leave do you take a year? What's a day off? Jokes aside, I actually can't remember a time when I was 100% away from work. Even when I might be at a friend's housewarming or visiting a new city, I am 24/7 terminally online.
