This YouTube interview (Nov 6, 2024) features Dr. Robert Whitfield discussing how digestion affects sleep and how wearables can track recovery. Key claims: late eating impairs the ability to fall and stay asleep (affecting hormone secretion, growth hormone, and glymphatic function). He compares wearables, stating Whoop is the most accurate he's used, Ultra Human ring measures HRV about 3 milliseconds different from Whoop, and Oura allows Bluetooth/off (airplane mode) to collect data with less EMF exposure. He gives HRV examples: his (age 55) typically 30–50, a low example of 18, and well-conditioned athletes may have HRV in the 100–200 range.

About 3 milliseconds different for HRV.
Typically between 30 and 50.

These are all just like basic things. And people who have problems with digestion are never going to sleep well. So if you eat late, there's no chance you're going to sleep. It's not going to happen. If you can stay asleep, all the fancy things that help you recover will happen. All of your hormones will get secreted, your growth hormone will get secreted. You'll get this thing that it's like a lymphatic massage for your brain, your glymphatic system will actually work. And then when you wake up, you'll feel like you rested now. They'll be like, all right, Dr. Wordsley, you say all this stuff so you can actually back it up. And there's several wearables. I wear whoop strap. I have an ultra human ring. I've worn oura rings. I like ultra human and whoop because they're super accurate.
More than aura.
Yeah. So a whoop is really the most accurate that I've had ever. And the ultra human ring is about 3 milliseconds different than my whoop for HRV. So for everybody listening, your heart rate variability just helps you establish how you're recovering. So in my patients that I had with the other day, come in and say, Dr. Whitfield, my HRV is 18. That's terrible.
What should it be at?
So, you know, I'm 55. Mine will sit between 30 to 50, which is not great. Someone who's a well conditioned athlete, who's young. It'll be 100, 200, because they're so fit. Like, we could all be 18 again. That'd be great. Wearables can help. You know, how long you were in deep sleep, how many sleep cycles you got?
So here's my question. What I like about oura ring is that you can turn the bluetooth off so you can wear it all day on airplane mode. It's still collecting data. And then, you know, at the end of the day, you can just like turn your bluetooth on for a second, get your data, see how you did or see how you slept over the night. And, you know, without EMF exposure. The other rings that you just mentioned, are you able to turn the bluetooth off on those?
No.
Okay. So to me, I would recommend aura.
More to my audience than those, just for bae listening. I get EMFs up the backside. I have two phones all the time and I have an ring on and a whoop strap. And Lord knows, yeah, I get, you know.
