One of the first things my Oura ring helped me figure out when I got it 4 years ago, was that if I eat a meal in the 4 hours before bedtime it interferes with my sleep. The effect was dramatic enough that Jackie and I switched to eating just two meals a day: breakfast an hour or two after we get up, and then our main meal of the day around 2:00 PM. Since that change, I’ve slept much better.

Sometimes though… life intervenes. Yesterday was one of those days. My local Esperanto group had its annual Zamenfest, and I brought pizza and cookies to the meeting, and ate a lot of both. (In fact, I not only ate several of the ginger sparkles I bought, I also ate some green star-shaped sugar cookies and some peanut butter cookies brought by other members of the group. It was a real cookie fest, as well as a Zamenfest.)

Unsurprisingly, I saw a repeat of the various issues that showed up 4 years ago, as can be seeing from looking at my Readiness metrics from my Oura ring:

The “Recovery index” basically means that my heart rate remained elevated until shortly before I woke up. That’s on top of the fact that it only got down to 53, which is rather high for me. My body temperature was 1.1℉ above baseline, which is probably just that my body was very active digesting food, rather than being a fever due to an infection or something.

A single day of this is no problem. Today I’ll eat on my usual schedule, and I expect I’ll sleep very well tonight. But I thought it was an interesting example of the sort of thing that the Oura ring is good at alerting the user to.

I didn’t get a picture of yesterday’s cookies, but here’s some from a prior year’s batch:
