Because my blog emails go out at 6AM every morning, many people think that I am up at 4AM every day typing away at my computer and drinking coffee. I do not get up this early. In fact, I’m naturally more of a night person. But since our world is heavily biased against night people, I do what I can to conform.

Perhaps because of this, I am very interested in sleep optimization. I have a Fitbit that I occasionally use, but I seem to go through phases with it. I think part of the problem is that the data I get from it doesn’t feel like enough.

This week I was intrigued to learn about something called the ŌURA ring. Yes, it’s another sleep and activity tracker. But it does some unique things. And because it’s a ring, it’s in constant contact with your finger’s arteries. So presumably the data is better.

The ring’s output appears to be centered around something called “readiness”, which the company refers to as “an optimal physical and mental state that can be achieved by acquiring the ultimate balance between sleep and activity.” 

To give a more concrete example, the ring tracks something known as heart rate variability (HRV). Fitbit and Apple devices don’t do this, but supposedly it’s quite a telling datapoint. Professional sports teams are starting to track this so they know how “ready” the players are.

I’m not yet sure I’m ready to invest in the ring (they start at USD$299), but I am definitely intrigued.
