BenGreenfieldFitness.com/oura This is a Premium podcast and is available - along with a protected vault of over 300 other audio episode, insider interviews, secret videos and downloadable .pdf's from the BenGreenfieldFitness show - when you . Enjoy! In an article I wrote 2 years ago about the "", I jokingly quipped that... "...here at the biohacking conference, I’ve seen a little bit of everything, but ultimately, we still need one device to rule them all – a la Tolkien’s magical ring. In other words, we need one simple wearable unit to be designed that 24-7 tracks heart rate variability, heart rate, pulse oximetry, global positioning, sleep, steps taken, calories burned, respiration, perspiration and skin temperature." So I was understandably a bit excited when I discovered . This small, stylish ring uses state-of-the-art miniaturized electronics to track and measure a host of parameters, including sleep, heart rate, heart rate variability (HRV), activity, body temperature, movement, respiration, and more. In today's podcast, I interview the Co-Founder and CEO of ŌURA ring: Petteri Lahtela. Petteri is a serial entrepreneur with 20+ years experience in creating market-leading high-tech products as well as building international businesses and market entries in dozens of countries. He has experience and expertise in Mobile telecoms, Healthcare IT Systems, Medical and Wellness Technology businesses as well as Healthcare and Wellness services. During our discussion, you'll discover: -How the ŌURA ring identifies deep sleep, REM sleep, light sleep, and periods of wakefulness, and how accurate this data is compared to actual sleep lab measurements... -Why the ŌURA ring is designed to allow you to completely disable the bluetooth function, and why the ring is specifically designed to not constantly transmit a signal (very important if you are concerned about electrical pollution)... -The infrared measurement used to analyze HRV, and why it is just as accurate at measuring HRV as wearing a chest strap... -How the Readiness Score you get from the ŌURA ring helps you identify days that are ideal for challenging yourself, and those that are better for taking it easy... -How something called your interbeat interval and pulse waveform can be used to accurately calculate your respiration rate... -The important data that you can collect about your body using the built-in accelerometer inside the ring... -How the ŌURA measures temperature, and what kind of health information you can discover by monitoring your body's temperature... -Why the ring was designed to withstand extremes of environment and temperature, such as hot saunas, cold water, etc. -How you can use the ring to track daily consumption (caffeine, alcohol, sugar), sleep aids you might be trying (valerian, melatonin, acupuncture) or other factors in your environment (barometric pressure, CO2, pollen count) using something called the Curious platform... -And much more!
