Welcome back to another episode of the Hano health podcast. I got another special one for you, and I don't mean to bombard you with all things, Ben Greenfield, but this is two weeks in a row that we wanted to release some content from Ben Greenfield.

Now it's not actually an interview with Ben Greenfield. It's actually me on Ben Greenfield's podcast. So if you're a follower of Ben Greenfield, you might have heard this one, but if not, you'll get the special opportunity to hear me being interviewed by Ben Greenfield on his podcast about all things HRV and Hanu.

Now this was a really special occasion for me as a podcaster, as a friend of Ben's. And the reason it was so special is because obviously we wanted to show Ben and his audience the world of Hanu. But one thing that I loved about this podcast that you will find really interesting is because Ben from the very beginning of the podcast has the Hanu strap on, he's got his app open and we walk through a lot of the features within the application. So he asked me questions on what he's seeing, why his data is doing what it's doing, etc. And I was able to provide an in-depth explanation of what's going with the app and device in real time.

We walk through many of the different features, like the resonance frequency assessment that you get to do making sure that you're tracking things like bolt score, doing all of these beautiful practices.

We talk about this idea of snapshot, which is like a testing feature morning readiness reading feature. All of the goodies are in there. So Ben and I unpack it all in this podcast so that I hope that you really enjoy this one because it was a blast for me to do and to be able to share with Ben's audience.

And I'm very grateful that Ben said to go ahead and share it with the Hanu audience as well. So if you've already listened to the podcast, yes, it's the one that I did withBen recently. But if you haven't listened to it, here's your opportunity to do it and to support Hanu while you do it by listening on our podcast, couple other ways that you can help support the podcast.

Then you can write to us: podcast@hanuhealth.com and we will send you a Hanu Health goody pack full of amazing Hanu and oxygen advantage gear. I hope that you really enjoy this podcast episode that I did with the one and only Ben Greenfield on his podcast. He's wearing this thing, telling you about what he sees and you will be able to experience this yourself soon.

-Resonance breathing and box breathing contrasted…41:45

• Physiological sighs – Andrew Huberman
