    I loved my Oura ring. I have a hard time sleeping and knowing I got X amount of hours, specifically under 7, it forces me to try and sleep more when my score is low. It helped me prioritize that and definitely just overall rest when it detected stress on my body. Very insightful.

    I think everyone needs one of these it should be standard. Healthy and especially if you healthy you needs to get this it can save your life. It monitors your health. This already save one of my friends doctors couldn’t fine anything out the ring as telling them something was off and sure enough they found she had cancer. Just saying that’s how a little thing like this can save your life.
