| Smartwatches may detect the signs of COVID-19 before you know you're sick - Engadget Posted: 18 Jan 2021 07:01 AM PST Smartwatches and fitness wearables may be able to play a valuable role in the early detection of COVID-19, according to recent studies. Researchers from Mount Sinai have found that the Apple Watch can detect small changes to a user's heartbeat that may indicate they have the coronavirus, a full week before they feel sick, as CBS News reported. One company is even developing a custom wearable to detect COVID-19 — all of which could help stop the spread of the disease by keeping asymptomatic folks at home. In a study titled called "Warrior Watch," the Mount Sinai researchers followed a group of 297 health care workers between April 29 and September 29. The participants wore Apple Watches equipped with special apps that measured changes in their heart rate variability (HRV). "The watch showed significant changes in HRV metrics up to seven days before individuals had a positive nasal swab confirming COVID-19 infection," said study author Robert P. Hirten, MD. A similar study done by Stanford University found that participants wearing a variety of trackers from Garmin, Fitbit, Apple and others found that 81 percent of patients testing positive for coronavirus had changes in their resting heart rate up to nine and half days prior to the onset of symptoms.
The ramifications of the studies are clear. "Developing a way to identify people who might be sick even before they know they are infected would really be a breakthrough in the management of COVID-19," Dr. Hirten said. "This technology allows us not only to track and predict health outcomes, but also to intervene in a timely and remote manner, which is essential during a pandemic that requires people to stay apart." The researchers aren't the only ones to notice that early COVID-19 symptoms that can be picked up by a smartwatch. A company called NeuTigers, born out of research from Princeton University, has developed an artificial intelligence product called CovidDeep that can help identify people with the virus in clinical situations or care homes. The company used a clinical-grade patient monitoring wearable, the Empatica E4, to take a variety of skin, heart-rate and blood pressure readings. Feeding that information into CovidDeep, they found they could detect the virus at a rate of 90 percent — more accurately than typical temperature screenings. They eventually plan to produce their own app that could work with Fitbit, Withings, Apple, Samsung and other smartwatches. Even without custom algorithms, a smartwatch or wearable could still be useful. The PGA Tour started using Whoop health trackers recently, and that may have helped player Nick Watney realize he was positive. "They've done studies where, if your respiratory rate goes up during the night... that's sort of a telltale sign that you might have something," said major champ Rory McIlroy back in June. "It was actually his Whoop that told [Watney] his respiratory rate went up, and that's why he thought maybe he could have it." This posting includes an audio/video/photo media file: Download Now |
| How to use your iPhone to get in shape and stay healthy - CNBC Posted: 17 Jan 2021 06:22 AM PST  Apple announces new app for health studies. Suorce: Apple Apple's main selling point for the Apple Watch is tracking your health, including activity, sleep and certain medical conditions. But it's not the only Apple product that can help you get in shape and stay healthy. The humble iPhone has plenty of health-tracking features as well. You might already know that you can track your steps, for example. But the Health app built-into your iPhone can do a lot more, like tracking how long you practice mindfulness through third-party apps, determining how long you spent in bed, your walking speed and more. Here are some examples of how the iPhone can help you get healthy: Step trackingTrack your steps on iPhone Apple The Health app can automatically track the number of steps you take in a day. It can also track the number of stairs climbed and total distance you've traveled. To do that:
View your steps and other metrics:
MindfulnessApple Health on iPhone Apple Apple doesn't have its own meditation app, unless you count some of the exercises in its Fitness+ subscription service, which has mindful cooldown and yoga workouts. But, it can keep track of the time you spend meditating in third-party apps like Calm or Headspace. If you install those apps you'll get a prompt to save information to Apple Health and, once you do, you can keep track of how long you meditate each day over time inside the app. Wind DownWind Down on iPhone Apple You need an Apple Watch to track your sleep, but the iPhone can keep track of how long you're in bed, and save that information. It's not a great analysis of your sleep but you can get an idea of your sleep patterns and if you pick up your iPhone at night. You can turn this on by selecting "options" under the "Full Schedule & Options" menu. The iPhone also has a "wind down" feature which automatically puts your iPhone in Do Not Disturb Mode and dims the screen. Once in that mode, you can set shortcuts on your lock screen to access meditation apps, a reading app like Kindle or Apple Books and more. I use it every night so my iPhone doesn't disturb me when I sleep. Here's how to turn it on:
Cycle trackingCycle tracking on iPhone Apple For women, the iPhone can track menstrual cycles and predict your next period and fertile windows. You can also keep a log of your period flow level, any symptoms you might have that you want to share with your doctor and more. It also can factor in things that might affect your fertility window, like pregnancy or contraception. Here's how to set it up:
Headphone audio levelsHeadphone Audio Levels Apple A feature called "Headphone Audio Levels" can keep track of how loud your headphone audio is and will let you know if you've listened to music too loud over the recommended limit. Listening to music at over 90 dB over four hours per week, for example, would trigger that alert. Here's how to set it up:
See your health recordsApple Health Recordss Apple You can keep track of the health records from your doctor visits if your physician's office supports integration with Apple Health. This lets you see all sorts of information, including immunizations, blood test results, past medical procedures and more. See if your doctor's office integrates with Apple Health
Review your health checklistHealth Checklist Apple Apple also has a "health checklist" built into iOS 14, which came out in September 2020. Health Checklist will help create a medical ID on your phone that you or someone else can show to first responders. It's got vital information such as whether or not you're an organ donor, the type of blood you have, allergies and reactions, medicine you're taking, your height and weight and more. You enter in this data yourself, so you don't have to include any of it if you don't want to. The health checklist can also help you set up the Emergency SOS, a feature on your iPhone that will automatically call emergency services if you tap the side button of the phone 5 times in rapid succession. If you press and hold the button, it will also send a message to any contacts you add in Emergency SOS. I have my immediate family members set up in mine, for example. |
