In this video I scientifically test the accuracy of two Oura Rings I wore at the same time. Subscribe to my weekly Newsletter(!) on www.robterhorst.com • Instagram: / quantified_scientist • Twitter: @QuantifiedRob • First, I test their sleep tracking accuracy by comparing them against a scientific EEG device. After that I compare that to the results of a full scientific sleep polysomnography test I did. I will also take a scientific look at heart rate variability, temperature, breathing rate, resting heart rate, and the readiness score. • 👇Amazon Affiliate* (paid) links, support the channel!👇 • Fitbit Charge 4: https://geni.us/wjAfjU • Fitbit Sense: https://geni.us/CSfYQE8 • Fitbit Inspire 2: https://geni.us/iZHlb • Apple Watch 40 mm: https://geni.us/0gNGeO • Apple Watch 44 mm: https://geni.us/7Dom • 📸My Gear📸 • Camera body (main): https://geni.us/SonyA6600_body • Camera lense (main): https://geni.us/sony_sel_18-135 • Camera (B-roll): https://geni.us/CanonEosM50MarkII • Light: https://geni.us/Godox_VL150 • Softbox: https://geni.us/NiceFotoSoftbox • Light stand: https://geni.us/WalimexLightstand • *My opinions are completely my own.
