We aren't quite finished with the edit on this one but thought you guys might appreciate an early release with a few extra background noises and 10% extra waffle.

If you notice anything terrible about the audio it would be very helpful to let us know so we can fix prior to release on the main feed.

Otherwise, here are some relevant links that are mentioned on the episode:

Okay, finally got a chance to get some work duhh...D'OOOOH! DAMN YOU Decoding the Gurus!!! :-D

Come on guy’s anecdotal evidence. That’s his argument. Can’t control for the olfactory context of the woods you walked . Why science it anyway? Touch grass and don’t sell me a pill 🙂🤣

Here's the ideal protocol for listening to a podcast: i) Download the podcast. MP3 mode is preferable as studies show more devices are MP3 compatible by around 40-50%. ii) Take four, maybe six deep breaths. iii) Press play. This is a vital step. Unless you press play it's likely the device won't play the MP3 at all. iv) As you listen remember to take regular breaks by pressing pause or taking the ear buds out of your ears to navigate traffic or reply to casual conversation. v) Rate the episode 5 stars. Unless you rate it 5 stars studies show that podcasters are likely to quit just before your next episode. vi) Repeat any views or opinions that made you feel good with the phrase 'science has shown' and mix the word 'protocol' in randomly.

So this Jack fellow sounds good and all but is he going to do a highly specific Norn Irish accent for 50-70% of the time?? And Matt are you going to go on and make him say six hundred and sixty six? Otherwise I don't know if we can trust him...

Re: Huberman - I've just finished listening to the episode and I think it's pretty inexcusable to have science communicators describe meta-analyses as reliable information if those meta-analyses actually identify that the research studied is low quality / has a high risk of bias. Yes Matt our own ABC does this too, and I've noticed this issue pop up in the Guardian from time to time - but I reckon this means they should *all* hang their heads in shame rather than Huberman getting off the hook. Idk if journos are too busy to fact check or what's going on but it's disappointing as it's an obvious way for misinformation and half-truths to gain popular currency.

Hmmm. I want sushi! But I do think Matt is right about there being something special about nature. I live in an appartment complex which is all about embracing biophollic design. Which means the buildings are literally draped in climbing plants and we have roof gardens and podium gardens and every appartment has a good sized balcony or courtyard with inbuilt garden boxes. And people will pay quite a bit more to live somewhere like this, compared to a standard appartment. That seems like some sort of argument for people getting a kick out of having more nature around them. I feel happier when I am surrounded by 🪴 🌿 🪴

Wait a sec, how much closer to a “sushi shop in the forest” do you want than fishing with your wife and kids in the Japanese wilderness? Chris was already living the Huberman-Kavanagh synergy dream without even knowing it!

Paul Sees

No defence of huberman, but on an epistemic level, why do we necessarily need to determine or even nominate a mechanism to acknowledge an effect and then to integrate that knowledge into our actions? Eg I don't need to understand gravity or nominate a mechanism for stuff falling to benefit from being careful around cliffs?

Ben Childs

I was surprised it wasn't mentioned, but to what extent are all of these theories regarding the benefits of nature just measuring quality of life and income level? It seems it would be easy in a low quality study to mistake the positive benefits of negative ions from living near running water, with the much more likely explanation that living in these areas usually requires a higher level of wealth.

Thanks for the podcast recommendations. I’ll check out the Kiwi one.

Thanks for this decoding Matt and Chris. Despite my despair in the way Andrew Huberman does not call out his buddies for their complete bullshit, I have and still remain an avid Huberman Lab listener. Being an Alcohol and Other Drug educator in schools, I find his episodes on substances and addiction really useful. I also like that he will have guests on who will be quite blunt to Huberman when he he is not on point. The 6 part series with Andy Galpin comes to mind. Additionally, I was also impressed with the way he did not indulge Chris Williamson's sexist narrative when he was on his podcast. However, I appeciate the way you guys put a spotlight on the way Huberman will gloss over or ignore important scientific process so as not to offend any of his audience or friends. Great job boys.

Only part way through so far, but the effect of UV light on circadian rhythm of most metazoans (animals) is well established, decent review in the corresponding Nobel Prize page for outlining the full human genetic pathway here: https://www.nobelprize.org/prizes/medicine/2017/advanced-information/ . Huberman doesn't mention this though. Doesn't fit the nature narrative per se, just a chemical reaction due to sunlight. It is just fine to get that sunlight in an urban environment. UV light also is necessary in mammals for processing Vitamin D. We can't actually ingest the final form, we store a precursor in our skin and the UV light converts it to usable Vitamin D. So again UV light is necessary for healthy mammals. It is a relatively small amount, half an hour or so a day for fairer-skinned people, 45mins to an hour for darker-skinned. Again nothing to do with nature per se, but instead just a chemical reaction. Not how Huberman frames it.

Adam Session

Finished and to add on to the discussion at the end: one of the main problems of the studies Huberman cites is the lack of controls for variable isolation. With it being shown that your average person does not get enough exercise or sunlight, really these studies need to have populations that get into nature as well as those that do exercise indoors, or just walk around an urban environment for proper experimental design in order to see if any increased health benefits are due to exercise and/or UV light exposure. Similarly, you can add groups that focus only on increasing relaxation/social time to consider those factors as well. That can be prohibitively expensive, but that is not a knock on the scientific process so much as the current control of academia.

Linda Sears

Perhaps I am a simpleton, but isn't one reason that humans like to be near running water is because millions of years of evolution has made it such that we and other animals associate running water with a good place to get a drink? Is it the sound that lets us know hydration is close by? The sight of it? The smell? The feel? It seems that focusing just on ions misses the whole experience. I understand they want to isolate a variable, like the ions, and test it to make the scientific process rigorous, but maybe it is better to just admit that not one aspect of running water is beneficial to our moods? (Big caveat here, I am on the humanities sides of thing, so I'm out of my depth). My biggest beef with Huberman is the focus on "performance," which translates as optimization lingo and the need for supplements and other bio-hacks to perform up to some standard that usually means getting a competitive edge by being highly productive (sort of like having your baby listen to Mozart to help it get into a better college). If I am only going into nature to make me more productive/competitive, I don't think I would feel so relaxed about it. I also agree that our view of nature would be negative if we were digging irrigation canals while being surrounded by thousands of biting insects and potential encounters with snakes. Still, I find natural environments to be beneficial for my mental health. Artificial environments that use nature as a guide are more pleasing to me than ones that do not. A noisy bar for me is overstimulating and causes anxiety.

1:28:34 // Chris // “[Jordan Peterson] starts crying when he talks about being at a dive bar and hearing some band play a bad cover.” 🤣🤣☠️

Fraser

Jack if you're in here I volunteer to be the Scottish co-host 🫡

Artemis Green

Ok Jack is a delight. He's like Matt but drier and kiwi flavoured. Crossover episode please.

Jennydiver

I think Chris was kind of losing it on the artificial environments, time for a sushi break. 😂

Chris Wishy

If anyone ever accuses you two of always agreeing with each other, you can now point them to your sushi vs the natural world debate 😂 great stuff as always 🙏

STEPHEN CARLTON

Good episode. Talking of grounding have you guys ever listened to Dave Asprey. I think he would be a good candidate for a decoding.
