While many Americans are struggling to lay off the snacks amid coronavirus state lockdowns, Twitter CEO Jack Dorsey has found plenty of ways to to pass the time.

Daily Mail UK

I recently found myself working 40 hours in only three days while writing and editing a draft—the high-intensity interval training of life as a writer. To help maintain the pace, I made sure to sleep for eight hours, worked out every day, and paused to eat the (at least semi-healthy) meals my husband made for me. But by day four, the words on my screen were swimming and swan-diving. My bullet-train hyperconsciousness blew off its rails. I was halfway incoherent and shivery-shaky. I was so out of it I tripped down three stairs, caught myself from falling the rest of the way, and then just sat down, bleary and mystified. I knew that if I kept going, I’d get sick or just shut down. To enable screen reader support, press ⌘+Option+Z To learn about keyboard shortcuts, press ⌘slash


Even as the world we live in rapidly shape-shifts, there are certain, research-backed truths. For one, we’re all pretty darn exhausted. The 2019 Philips Global Sleep Survey released last year asked more than 11,000 adults from 12 countries about their quality and quantity of shut-eye, and only 10 percent reported sleeping “extremely well.” Combined with other pieces of glaring data about our lackluster REM habits, it’s imminently clear that so few of us are waking up well-rested each day. That’s why sleep wearables, like the Oura Ring, are stepping in to make sure we’re counting key somnolent metrics—like our latency, HRV balance, and body temperature.

Okay so, it may sound like I'm being overly effusive about how curative sleep can be, but believe me when I say I am not even scratching the surface. After thousands of studies, it remains core to our physical and mental health at every level, from balancing our immune systems, our microbiomes, our metabolisms, our cognitive function, our dopamine levels and beyond.

Researchers are gathering data from thousands of Americans to create an "early warning system" that can identify people in the early stages of COVID-19.

US News & World Report

Between the lack of widespread coronavirus testing and a growing number of asymptomatic coronavirus infections, tracking the spread of COVID-19—let alone containing it—has been extremely difficult. Reminder: People who are infected can still spread the coronavirus, even if they aren't showing symptoms. In fact, it's now believed that roughly 25 percent of people infected with COVID-19 may not show any symptoms of the illness, Robert Redfield, M.D., director of the Centers for Disease Control and Prevention (CDC), recently told NPR. In an effort to better identify asymptomatic people with the coronavirus, researchers are now exploring whether wearable fitness trackers—and the health data they measure (heart rate, sleep cycles, etc.)—may provide early clues for users who may be infected with the coronavirus but aren't aware of any obvious symptoms.

As scientists and researchers battle to understand more about COVID-19, consumer data is becoming an even more critical tool in understanding the spread of the pandemic.

Wearing a smart watch or fitness tracker helps many of us keep an eye on our activity levels, heart rate and sleep. Now, a new study from the University of California, San Francisco, is using a smart ring called Oura to determine whether data such as body temperature, along with a daily symptom survey, may be able to detect the early onset of COVID-19.


Poor sleep is fuelled by everything from auto-play streaming services to the rise in millennial anxiety. And yet, new and alarming research is telling us more than ever about its dangers, from higher rates of heart disease to doubling our risk of cancer. But now, coming to the rescue is a £100 billion sleeping giant, as tech titans and start-ups repackage rest as the ultimate wellness cure.

We're all concerned about diagnosing the Coronavirus, so it's a shame Apple Watch can’t take our temperatures. Neither can an WearOS smartwatch or the Fitbit Versa. During a time when more people than ever are concerned about having a fever, it’s a shortcoming that seems particularly glaring.

We’re a nation obsessed with sleep – or, statistics show, the fact we’re not getting enough of it. Some 22 per cent of us struggle to drift off every single night in the UK, and a 148 per cent spike in NHS melatonin prescriptions between June 2014 and May 2019 suggests we’re heading towards an epidemic. While we’re frequently advised to avoid tech at all costs before bed to boost our chances of nodding off, there are some gadgets that can actually aid us in our pursuit of a great night’s sleep. Here, British Vogue highlights five of the best.

If you skip an hour of sleep, you'll likely wake up feeling more groggy and crankier than usual, but what if you end up missing out on two or three hours? Or what if that single skipped hour or two turns into a regular habit, where you are losing sleep on a nightly basis?

With tech innovation happening at an unprecedented fast pace, businesses and entrepreneurs need to stay abreast of the latest developments and find ways to leverage new technology to make life easier. For entrepreneurs especially, using the right technological tools can streamline work and free up more time, helping them attain that ever-elusive but much needed work-life balance.


Smart rings are still a relatively young category in the wearable hardware world, but the Oura Ring seems to be a standout in terms of early success.

The Oura Ring hardware is sleek and packed with sensors, allowing it to measure a user’s sleep patterns, take your body temperature and track activity, and now Oura has raised $28 million in Series B funding to bring on new key hires and product updates

Tech Crunch

The tech community has been vocal about its love of the $299 Oura sleep ring, and the startup has raised money accordingly. Today the Oulu, Finland-based company is announcing a $28 million fund raise from Forerunner Ventures as well as Dorsey’s company Square, among others. Oura has sold 150,000 rings to date and is launching a new website with articles on how to sleep better.

Oura, a Finnish startup that creates a smart activity- and sleep-tracking ring, has raised $28 million in a series B round of funding from Google’s Gradient Ventures, Jack Dorsey’s Square, and Forerunner Ventures.

Founded out of Oulu, Finland in 2013, Oura monitors the user’s pulse, movement, and temperature to deliver a “holistic picture” of their health. And unlike many other health trackers on the market, the device is not worn on a person’s wrist — instead sliding firmly onto their finger.

A slew of wearable devices from rings to wrist-worn trackers hit the market in 2019, claiming to help people learn more about their sleep.

They’re serving a big market, with research showing that more than 60 million Americans suffer from some kind of sleep disorder. The so-called “exhaustion economy” is thriving globally, as consumers and even their employers are starting to pay for consulting services, special mattresses, and more.


One of the most impactful changes I have made lately is improving my sleep, namely my sleep timing. This was inspired by tracking my sleep using an Oura Ring. If you have not tracked your sleep, I highly recommend you do. Even though I am generally not a big advocate of tracking, this is one area I feel is worthwhile. In today’s episode, I talk with the CEO of Oura Ring, Harpreet Rai about the many health benefits of sleep.

When the Apple Watch was first announced in late 2014, the general public’s reaction was, basically, “Why?” Why do I need a mini phone on my wrist when my phone is in my pocket? Why do I need to pay $350 (or more) for a step tracker when my Fitbit costs less than a third of that? Now, five years later, the answer is becoming clear: Thanks to rapid advances in technology, the Apple Watch and other wearable fitness trackers aren’t so much mini smartphones as they are personalized health-care devices, arming users with easy-to-digest snapshots of their activity and recovery data in order to optimize their health and wellness. And in 2020, new gadgets, features, and health-care applications for this tech will reach more people than ever before.

Meanwhile, I’m sick as a dog with a virus I caught from my 3-year-old, I’m on deadline for what feels like a bazillion stories, and I’m pregnant, which means I need coffee but can’t have too much, and need sleep but can only lay on my left side, and can’t breathe without sitting propped up with a pillow anyway, since I can’t safely take any cold medication.

Prince Harry and Meghan Markle are on a whirlwind tour of Australia, New Zealand, and the surrounding environs. Meghan has been predictably helping brands sell out shoes and garments she’s been wearing at appearances there, thanks to the “Markle effect.”


The first generation of Oura's smart ring was little more than a proof of concept, showing it was possible to put a fitness tracker on a finger. But you can understand why folks might have thought twice about wearing one of the massive pieces of jewelry. Inconspicuousness is the watchword for the second generation of the device, which at least does look like an actual ring.


I spent a good part of 2016 writing a book about wearable devices, so I got to take a deep dive into each category of wearables. The more I dug in, the more I realized that they’re just not that useful. Smartwatches are second-screens for the notification layer of our phone, and function only as a reminder to stare at our phones during the few moments of our lives that we’re not already staring at our phones.

Our users are very committed and our retention rates are much higher compared to wearables in general. We need to continue innovating in all areas to maintain our pioneering position,” concludes Lahtela.


Mr. Kevin Lin , the co-founder and former COO of Twitch, has been appointed chairman of the board.

Oura Health, the Finnish health technology company, announces the world’s most Advanced wearable that helps you achieve restorative sleep. The new truly ring-sized Oura ring helps users sleep better and align to their natural circadian rhythm.




Today, Oura Health announced their second-generation smart ring that tracks sleep, recovery and daily activities: the new Oura ring. The new ring and the companion app offer daily advice to help users learn how to get more restorative sleep and align their lifestyle to their natural circadian rhythm. The guidance helps users understand how their body responds to their lifestyle. By analyzing sleep, activity levels and physiological responses of the body it provides personalized insights to maintain good health and optimal performance.


The second-generation Oura ring is less than half the size of the original ring and has a seven day battery life. Oura’s sleep analysis has been independently validated by SRI International . The data provided by the Oura ring helps users live a better life, with in-depth sleep improvement programs and personalized circadian alignment guidance, which helps users understand their optimal times for sleeping, working out, and even eating.


“The new Oura ring uniquely combines beautiful design and pioneering technology with ultimate wearing comfort and scientific accuracy. The new ring is a real leap forward in technology – its processing power is ten-fold compared to the first Oura ring and even with added functionality the battery lasts up to one week with a single charge, ” says Kari Kivelä, CTO, Head of Design and Co-Founder at Oura Health.


During the night, the new Oura ring tracks sleep quality, sleep stages (deep, REM, light and wakefulness), ECG level resting heart rate and heart rate variability as well as body temperature. With the new ring, users can also see their resting heart rate and heart rate variability on-demand during the day, for example during naps, meditation or breathing and relaxation exercises.


The new Oura ring builds on the success of the pioneering first-generation Oura ring.“ Since 2015 we have already helped users in over 50 countries achieve better sleep and performance. We are very grateful for all the devoted customers and high user satisfaction, proven by the retention rates that are three times higher compared to other wearables,” says Petteri Lahtela, CEO and Co-Founder at Oura Health.


The new Oura ring is the world’s first consumer-available wearable that offers guidance on how to improve the individual circadian alignment. The circadian rhythm is the body’s natural 24-hour clock that affects everything you do: when it would be optimal for you to sleep, rest, eat, and move. The new Oura ring helps you better align your lifestyle, activities and sleep habits to your unique and natural circadian rhythm. For example, Oura helps you find your optimal bedtime to ensure more restorative sleep and good recovery from daily mental and physical strain.


The new Oura ring is available for preorder at . The new ring is made of titanium, it’s water resistant up 100 meters (328 ft.) and it comes in three unique designs and four color options

The new Oura ring comes with advanced sleep tracking features and daily guidance that helps users align their lifestyle, activities and sleep habits to their natural circadian rhythm – the 24-hour genetic clock that regulates the functions of the human body. Improving sleep and better aligning to your natural circadian rhythm can help users perform better at work, improve their athletic performance and live life at their full capacity.

Advanced Sleep Tracking

The new Oura ring builds on the success of the pioneering first-generation Oura ring. It tracks sleep timing, sleep stages, night-time resting heart rate and heart rate variability, among other metrics. An improved temperature sensor is capable of tracking changes in nocturnal skin temperature with at least a 0.05 centigrade resolution.

Using the free Oura app (iOS and Android), users can get an overview of their previous night’s sleep and sleep quality. The new ring will be accompanied by the updated Oura app that enables users to follow up on long-term trends and see changes over weeks, months and years.

“Improving sleep is not a one-off feat. It’s a commitment,” says Kari Kivelä, the Co-Founder and Head of Design at Oura. “To make lasting changes and see results, the sleep monitor has to be durable, beautifully designed and comfortable to wear day and night. The new Oura ring gives users the ability to track their sleep, learn about their unique sleeping patterns, make changes in

their daily lives and see them reflected in their sleep and readiness. It’s the perfect tool for self-reflection and improvement.”

Oura’s sleep analysis has been independently validated by SRI International. The new ring is set to bring even better accuracy and make it the go-to tool for longitudinal sleep research as well as the perfect validation tool for biohackers and discerning individuals.

Align to Your Circadian Rhythm

The circadian rhythm is the body’s natural 24-hour clock that affects everything we do: when we should sleep, eat, rest and move. Studies have linked circadian alignment with better mood, and better cardiovascular and metabolic health. The new Oura ring is the first consumer-available wearable that offers guidance on how to improve your circadian alignment. The guidance is based on the user’s personal sleep, activity and physiological responses tracked over weeks and months. Oura will identify optimal bedtimes, identify and promote sleep improving habits and provide personalized activity guidance.

“The new Oura ring is the future of sleep tracking and guidance. It’s the first truly personal and actionable device for improving sleep and aligning with your circadian rhythm,” says Hannu Kinnunen, the Chief Scientist at Oura. “What makes this possible is our database of over a million individual nights. We can utilize machine-learning to uncover previously hidden trends and patterns to serve individual people and help them understand themselves better.”

“We are all unique, with our own unique rhythms but society has a tendency to favor morning people. As a result many live and sleep out of sync with their natural circadian rhythm. We are about to change that. This is the first time that we can start pointing out the best time to go to sleep, be active and recover. Not for averages, or ideals – but you,” says Hannu Kinnunen.

Moment offers on-demand meditation tracking by measuring resting heart rate and heart rate variability (HRV), two data points highly correlated with stress and heart health. Oura Ring users can now track the impact of their meditation sessions to get actionable information about their practice and its effect on their bodies.

Moment builds on Oura Ring’s sleep tracking features, which provide users with information about their heart rate, heart rate variability, body temperature, respiratory rate, and sleep stages, producing a daily Sleep Score and Readiness Score. By analyzing a user’s trends over time, the Oura app is able to suggest an optimal sleep schedule, advise on recovery, and confirm readiness for physical training.

Moment Details

  • Moment quantifies mindful moments and meditation practices to illustrate the link between mind and body like never before
  • HRV data encourages users to self-study how different meditation sessions affect them physiologically, leading to an optimized routine
  • Users experiment with their practice to see how choices like increasing or decreasing time spent meditating effects resting heart rate and heart rate variability
  • Moment was designed to be versatile because mindfulness is personal — there is no right or wrong way to take a breather
  • No prescriptive programs or must-follow instructions; can be used with the user’s favorite guided meditation app or video, or to develop a freeform practice

“Building the life you want takes focus, work, resiliency, inspiration, and support. Sustaining YOU is about rest and recovery.

“I use an Oura Ring to fine-tune the biggest human hack everyone should use… An amazing night of sleep. We often sacrifice the only thing that helps us be the best we can be. Thanks to the new Moment feature in the app, I can now track my naps, meditation and body status at any moment of the day. Owning 5 different companies, I can find myself being in the middle chaos quite often. I love taking a moment to breathe and calm down to come back stronger for our team. Being able to see my HRV and heart rate tracking helps me improve the way I recharge in a short period of time.” -Marc Fitt, serial entrepreneur and world-class fitness model
