"ABSTRACT Background: Heart rate variability (HRV), or variation in beat-to-beat intervals of the heart, is a quantitative measure of autonomic regulation of the cardiovascular system. Low HRV derived from electrocardiogram (ECG) recordings is reported to be related to physical frailty in older adults. Recent advances in wearable technology offer opportunities to more easily integrate monitoring of HRV into regular clinical geriatric health assessments. However, signals obtained from ECG versus wearable photoplethysmography (PPG) devices are different, and a critical first step preceding their widespread use is to determine whether HRV metrics derived from PPG devices also relate to older adults' physical function."

Everyone ages at different rates. Our "true age" (also called "biological age") depends on how much inflammation we encounter in our lifestyle and environment, combining with our genetics. True age represents our capacity for resilience, in tolerating and recovering from these life stresses. By increasing this resilience, we could even get younger in true age! It requires frequent tracking of biomarkers like heart rate variability (HRV).

Oura ring's Moments feature measures HRV. This is how we measure wellbeing. Test and measurement of wellbeing opens the door for so many interesting self studies. This should be one of the experimental choices in our new online class.

Click to download the PDF. Oura's primary goal is to help UCSF engage and increase the number of users who have rings and are opting in to early detection efforts. Oura is offering rings at $250 for orders of 1000 rings supporting TemPredict. Immediate impact: Participants are presented every morning with daily personalized insights on heart rate, HRv, respiration, temperature, sleep staging, and activity to empower them to monitor their own health and change their behavior accordingly. This is especially important in medical personnel and high-risk patients. Future impact: UCSF will leverage Oura's backend data to build models that can aid in identifying symptom profiles, pinpointing at risk populations, predicting severity, and validating recovery, containment, and treatment efforts. The data gathered now may be our only chance to measure these changes so we can recognize them and deploy predictive algorithms to minimize the next wave of this outbreak, expected in Fall 2020. We ask all donors to go to OuraRing.com and buy rings for medical personnel so they can join this effort.

About this podcast Sometimes it seems like you need Ninja skills to defeat Lyme disease. Join acupuncturist Mackay Rippey and his producer, Aurora, as they bring you interviews with interesting and informative people who are using their unique skills and knowledge to deal with Lyme and other tick born diseases. My name is Mackay Rippey, I'm an acupuncturist in Clinton, NY (http://www.mackayrippey.com)and the host of Lyme Ninja Radio. I'll never forget the Sunday morning I dragged my sorry-feeling-self to the bathroom and found a perfectly formed bullseye on my left arm. I was lucky, able to return to my acupuncture practice after only few days. It's possible to beat the bacteria that are making you sick. I have and so have many others, but you have to be smarter than Lyme. That's why I created Lyme Ninja Radio. Join us as we talk to some of the most interesting people in the Lyme community.
