Cumulative Stress measures factors of chronic stress. Oura also announced an app redesign and several other new features. Your Oura Ring could soon tell you when you're burnt out. Oura unveiled Cumulative Stress, a new stress-tracking feature, on Monday alongside a bevy of software updates. Cumulative Stress Oura validated Cumulative Stress against the Perceived Stress Scale and Copenhagen Burnout Inventory to measure stress contributors like sleep continuity, heart rate response, sleep micromotions, temperature regulation, and activity impact. Also: I wore the Oura Ring 4 Ceramic for a week, and it shattered the myth of ugly fitness tech These five factors depict the body's long-term response to stress in a way that Daytime Stress, which is effectively Oura's graph of a user's daily heart rate, cannot. "These insights highlight the often 'hidden toll' of unmanaged strain before it manifests as fatigue, burnout, or illness," Oura writes in a press release. The feature measures the past month of Oura biometric data and will launch alongside Stress Management. This view illustrates stress patterns on a daily and long-term basis. More Oura app updates Oura unveiled several new features on Monday that are coming to the Oura app in the coming weeks. Here's what else is new and when you can expect to see them on your smart ring app. Also: Why your Oura Ring battery is dying quicker (and what Oura is doing about it) The Today tab, the first page a user sees when opening the app, looks a little different now. Instead of bombarding a user with scores and numbers, Oura will now focus on "One Big Thing" -- that is, the most relevant scores and information du jour. The information changes throughout the day to offer useful insights about last night's sleep in the morning or activity levels mid-day. Cycle Insights, its fertility and menstrual tracking feature, sees some changes as well. The feature is expanding from a one-month view to a 12-month view, and users can get personalized information on their cycle phase and prediction data faster. Instead of 60 nights of sleep for this data, they only have to wear the ring to sleep for one night. Also: The Oura Ring is the Department of Defense's not-so-secret weapon Lastly, Oura seems to be cooking up a blood pressure feature of its own -- and it's working with the FDA to do so (will it rival Apple Watch's new Hypertension Detection feature?). Before the feature rolls out, though, it's launching a Blood Pressure Profile study that explores early signs of hypertension through the smart ring's passive monitoring, planned to launch in the coming months. The feature could launch experimentally through Oura Labs, through which users can be notified of possible hypertension. Users fill out a questionnaire about their medical and family history and receive feedback on whether there are minor, moderate, or major signs of hypertension.
