Real talk? This is probably my favorite gadget that I own. More than a sleep tracker, it doesn't just tell you how much REM you did (or didn't) get last night. It tracks a multitude of biological processes through examining temperature, heart rate AND heart rate variability (they're different, cross my.....well, you know), respiratory rate, and more. It creates a comprehensive explanation after each night of sleep that provides you with your "readiness score" - a metric of how well rested you are and how much you recovered during sleep. It has completely changed the way I approach sleep hygiene and I can't go a day without it.
Creating healthy sleep hygiene isn't just important for overall health, it's imperative. If you get a work out in too late in the day, eat a late meal, or go for that extra glass of vino, your body feels it. Ōura will help you see it, so that you can improve your overall sleep quality. That way, when you do get in a late run or dinner, you'll recover faster.
