This one is for couples who’ve been entangled in blanket wars for years. For women whose bodies spike and shift with cycles, pregnancy, and menopause. This one’s about so much more than the science, the metrics, and the engineering. This one’s about waking up and loving how you feel. So tell us, how do you love it?

We've been named one of @FastCompany's Most Innovative Companies of 2026. This is our fourth year on the list. When we founded the company, no one believed your time in bed could meaningfully change your health. The night was the most underutilized lever in human performance — and we set out to change that. Ten years later, the Pod doesn't just track your sleep. It reads what's coming and adjusts before disruption hits, reducing menopausal hot flashes, helping you fall deeper into sleep, and cutting the time you spend lying awake. Built on over a billion hours of real sleep data across 34 countries. A dataset no other company has. This year: a $1.5B valuation, peer-reviewed research proving we restore the body's natural circadian rhythm during sleep, and an FDA filing for sleep apnea detection. We are not building a better sleep tracker. We are building the defining health technology company of this generation. This recognition belongs to everyone who bet on sleep before it was obvious — our team, our athletes, our members. The future of health starts tonight.

Southwest friends. It’s 106°F in March. That’s not normal. Your sleep tonight probably won’t be either. Here’s what to know: Your body drops its core temperature about 2°F to fall asleep. When your bedroom is 80°F+, that process stalls. Deep sleep suffers. REM suffers. You wake up feeling worse than when you laid down. Tonight and every night this week, cool your bed not just your room: → Lighter sheets → No alcohol close to bedtime → Get your sleep surface as cold as possible, that's where your body loses heat We’re obsessed with sleep so you don’t have to 🫡
Jorge Torres@JorgeTWeather

Phoenix history is about to be made. A high of 101° today would be the earliest 100-degree day ever recorded and the hottest temperature ever recorded in March. Then 105° Thursday. 106° Friday. Heat we don't see until late May. Extreme Heat Warnings in effect Thu-Sun🌡️

140.6 miles. That's what they call an IRONMAN. But that number is missing something. Every swim, every climb, every mile starts the night before. It's built across hundreds of nights of recovery, the part of training that happens in the dark and rarely gets talked about. IRONMAN athletes track every watt, every split, every gram of nutrition, yet sleep, the variable that governs cardiovascular recovery, muscle repair, and cognitive readiness, has historically been left to chance. That's the gap we're here to close. Eight Sleep is proud to be the Official Sleep Fitness Partner of IRONMAN® Europe. Athletes on the Pod report 34% more deep sleep and a 15% improvement in cardiovascular recovery metrics including HRV, resting heart rate, and respiratory rate. For endurance athletes building across training blocks and a full race season, those gains compound into something that matters on race day. To every IRONMAN athlete: we see you. The dark mornings. The discipline. The quiet, relentless commitment to becoming who you are capable of being. We're honored to be part of your journey. IRONMAN athletes, we have something for you → bit.ly/4bBnkhs

WORLD SLEEP DAY is here, and we have something for you We released the largest sleep report ever built, based on research by Eight Sleep at eightsleep.com/stateofsleep. The global average: 7.28 hours of sleep, 18.4% deep sleep, 22.9% REM, 11:22 PM bedtime. That's the baseline from 10.2 million nights. Most sleep research works with hundreds. We worked with millions. Here's how the world actually sleeps: The country rankings: - Netherlands sleeps the most (7h 20m) - UAE gets the best deep sleep (18.9%) - Switzerland leads REM (23.7%) - Australia goes to bed earliest (10:56 PM) - Spain goes to bed latest (12:23 AM) 87 minutes separate Australia and Spain Same species, very different habits. The UAE is the most efficient sleeper in the dataset. Shortest duration (7h 04m) but highest deep sleep percentage (18.9%). The Netherlands sleeps the longest but sits mid-pack on deep sleep. Duration and quality are not the same conversation. June is the worst month for sleep (7h 07m). January is the best (7h 24m). 16-minute gap. Longer daylight suppresses melatonin. Summer sleep is shorter. But deep sleep actually peaks in June (18.9%). Your body compensates by going deeper when time is shorter.

ALERT: News Is the Worst Bedtime Content Of 12 content types we tested, only one had a measurable negative impact on sleep quality: news. Viewing news within an hour of bed reduced REM sleep by 2%. That might sound small, but REM is the sleep stage responsible for memory consolidation, emotional regulation, and cognitive recovery. Lose 2% per night and over a week, you're down roughly 70 minutes of REM. Social media? No effect. Short-form video? No effect. Long-form video, audio content, gaming? None of them moved the needle on sleep quality. The study covered 248 Eight Sleep members and 1,700 nights. Every participant reported their content type, duration, emotional response, and attention level. We paired those with objective Pod sleep data. News was the outlier. Not because of screen time. Not because of blue light. But likely because news content is specifically designed to trigger alertness, urgency, and cognitive engagement right when your brain needs the opposite. Swap the news for a podcast. Your REM will thank you.

The Pod measures your heart rate, HRV, and breathing every night. You don't wear anything. Here's how that works ⬇️⬇️ Inside the Pod cover is a thin strip of piezoelectric sensors at chest level. Every heartbeat and breath creates a tiny vibration. The strip picks it up. Think of it like a microphone for your body's movements. Except you never know it's there. The raw signal is messy. Slow waves = breathing. Sharp peaks = heartbeats. All mixed together. Digital signal processing cleans it up. Machine learning extracts the numbers. HR, HRV, breath rate. All from vibrations in your Pod. We validated against medical-grade ECGs and respiratory belts. Over 400 lab hours and 1,500 nights. 99% HR accuracy. 95% HRV. 98% breath rate. Those aren't marketing numbers. Those are clinical numbers. No wearable. No charging. No forgetting to put it on. The @eightsleep Pod reads your biometrics while you sleep. That data powers your sleep stages, recovery scores, and everything else. Hospital-grade. Zero effort.

Every Daylight Saving Time guide says the same things. Shift your schedule. Get sunlight. Limit caffeine. Almost none of them mention temperature. Falling asleep requires a core body temperature drop of about 0.5–1.0°C. When DST forces you to bed earlier than your body expects, that drop hasn't happened yet. You lie there awake. Not because you're anxious. Because you're still too warm. On the other end, core temp rises before wake to promote alertness. After the clocks change, your alarm fires before that rise. That's why those first mornings feel worse than "just one hour less." The Pod handles both sides. Night Phase cooling triggers the temperature drop sooner. Warm Final Phase replaces the wake signal your circadian system hasn't adjusted to yet. And Sleep Balance shows you the cost. Every night you miss that temperature window, it shows up in your 7-night balance. The debt is quantified. The trend is visible. Light resets your clock. Temperature makes the reset feel natural. Sleep Balance tells you if it worked. Read more at bit.ly/46GUkTR

The instinct after a rough week of sleep: crash on Saturday. Sleep until noon. Feel human again. The data says that makes it worse. Long weekend sleep-ins shift your circadian rhythm later, making Monday even harder. It's called social jetlag. You're giving yourself a timezone change without leaving your bed. Sleep Balance is designed around this reality. It tracks your rolling 7-night deficit and shows that consistent, slightly earlier bedtimes close debt faster than one 12-hour Saturday. 30–45 minutes earlier each night is more sustainable and more effective. The Pod supports this. Temperature adjustments overnight promote the deeper sleep stages that recover debt faster than light sleep alone. You don't need more hours. You need better ones. If your Sleep Balance is trending toward debt, you'll know. And you'll know whether your recovery strategy is actually working or whether you're just rearranging hours without closing the gap. Check yours in the app. The weekly and monthly trend views show the full picture. Read more at bit.ly/46GUkTR

"I'll catch up on the weekend." Sleep Balance has heard that one before. Most people know they're tired. Almost nobody knows by how much. Sleep Balance changes that. It tracks the rolling 7-night gap between the sleep you're getting and the sleep you actually need. Not a generic "8 hours" target. Your number is built from 90 days of your data on the Pod. The timing matters: Daylight Saving Time hits March 8th. That lost hour doesn't exist in isolation. It stacks on whatever debt you were already carrying. The late nights, the early alarms, the weeks where "I'll catch up this weekend" never materialized. Miss 30 minutes a night for a week and you're 3.5 hours behind. Research links that kind of deficit to impaired memory, elevated cortisol, and slower reaction times. Your brain registers the debt before you consciously feel it. The fix isn't dramatic. Starting earlier, shift bedtime 15–20 minutes earlier each night. Sunlight within 30 minutes of waking. Caffeine done 8+ hours before bed. By Sunday, the full hour is absorbed. Sleep Balance shows you the whole arc: debt building, debt closing, day by day. You're not guessing anymore. Check yours on the Eight Sleep app. The number might surprise you.

For most menopausal women, the hot flash options are: take HRT or deal with it. Our new study just added a third option. The Pod reduced nighttime hot flashes by 56% in one week. 85% of women saw improvement. No medication required. And it worked just as well for women already on HRT as for women who aren't. That second part matters. A lot of women can't use HRT. Contraindications, side effects, personal preference. The non-pharmacological options until now have been "keep the room cool" and "wear lighter clothes." That's not a solution. That's a shrug. The Pod actively lowers core and skin temperature throughout the night. It doesn't just cool the surface. It targets the physiology that triggers hot flashes. 12% better sleep quality. 9% fewer menopausal symptoms. 98 women. 14 nights. HRT works. But it shouldn't be the only answer.

.@Charles_Leclerc monitors HRV, heart rate, and sleep metrics year-round. But during pre-season? He sleeps 10-11 hours a night on the @eightsleep Pod to maximize deep sleep and recovery. Not because the work is light. Because his training days look like this: → 7 AM wake-up → 3-5 hours of cardio (ski touring, endurance work) → 45-minute nap ("not optional," per Leclerc) → 60 minute heavy straight → Recovery sessions: spa, massage, Eight Sleep Pod "Without sleep, overload would simply become fatigue. With sleep, it becomes progress." Pre-season is the only window where an F1 driver can truly push the body. No race weekends to manage around. The tool that makes it work: the Eight Sleep Pod. Temperature regulation that keeps the body cool during deep sleep and warms gradually before wake-up. For an athlete pushing 10-hour training days across weeks, those improvements in sleep quality compound into measurable performance gains. Before the first race, the work is already done.

This is the future we've been building toward. Sleep was the entry point. The destination is a system that understands your body better each night and acts on that knowledge, across every dimension of personal health.
Matteo Franceschetti@m_franceschetti

Today we're announcing a new round of funding that values @eightsleep at $1.5 billion, led by @tether Investments. Ten years ago I started Eight Sleep with one conviction: the night is the most underutilized lever in human health. Almost nobody was engineering their sleep. Last year, we hit free cash flow positivity, launched 3 new products, expanded to 34 countries, and published peer-reviewed studies showing the Pod reduces menopausal hot flashes by 56% and restores the body's natural circadian temperature rhythm during sleep, lowering core body temperature and improving cardiovascular recovery. A product you sleep on is producing clinical outcomes that rival pharmaceutical interventions. We're now building a predictive AI agent trained on 1B+ hours of sleep data. It anticipates your night before it happens. And we're advancing FDA filings for sleep apnea detection. Passive. Every night. No wires, no clinic visits. The night is just the beginning.
