    I look forward to seeing a lifehacking hyper-optimizer streamline this to a polished daily workflow...

    "I have a bucket of mud, in which I stick my hands for 15 minutes every morning.

    Every weekend, I inoculate at a 1:5:5 ratio with biologically active stream dirt (after petri-dishing to check for activity), and a mix of poor-quality soil cover, and some compost; I finish by adding a 10-10-10 balanced fertilizer.

    Recently, I've been seeing if there are any additional benefits to smearing all over my arms; I'm conducting a 3 month/3 month comparison experiment, with a washout period in-between...

      There's something very sad about all these people spending so much energy on crazy intensive n of 1 experiments.

      If we could only get them to collaborate, we could get some real knowledge out of it!

      I made the mistake of looking at /r/sauna on Reddit once or twice recently, and there was a lot of people doing very similar things.

      "I take my preworkout, do my exercise, then I sit for 12 minutes at 90 degrees in sauna, before three minutes in the cold plunge-pool at 8 degrees, before going to sauna again for 19 minutes and I finish with a seven minute warm shower".

      Just the thought of looking at a watch in a sauna, and timing things minute by minute sounded exhausting.

      I assume going to sauna takes an hour, it might be I leave it on for a couple of hours, but beyond that the minutes inside/outside are a mystery and I like it like that. Same story with being outdoors in a cabin/cottage. I might dig up some plants, or move the hammock around, but whether I get (literally) dirty is just down to whatever random things I've done that day!

        Do you mean you literally sit in the sauna for hour?
        • piva00 1 hour ago
          I don't think anyone is capable to sit in a 90-100C sauna for a whole hour without breaks, otherwise with breaks I surely have been in a sauna for more than an hour.

          Just this summer I was at a cottage by Vänern (the largest lake in Sweden), the sauna was built right at the lake with a pier setup for jumping into it, we had a party going late into the night where you constantly moved from the sauna into the lake, out of the lake, have chats, a beer, into the sauna again, rinse and repeat for some 8-10 hours. I have no idea exactly how long I was in the sauna but it was definitely more than a couple of hours in the whole affair :)

            If you ever basta in winter, try bringing ice into the sauna. Smearing yourself with ice while in the heat is really nice :)

            Yes, I definitely do agree with that. I too love what you're describing - we have some of that in Poland too :)

            However, I was not sure if we're talking about it - or some American version I know only from various memes - where people are coming in with phones and in shoes.

          I understand that as the general act of getting up, starting the sauna, going for your clothes change, resting a couple times, going to the kitchen for water, shower, switch off, kitchen again, whatever... you've filled an hour of your time.

          • KptMarchewa 2 minutes ago
            That interpretation does make sense. Just heating the sauna can take even longer.

      There’s a startup opportunity: a body cream with concentrates of beneficial microorganisms.

        I thought sun exposure was bad. Or is it good again? Was it good all along?

        Do I need to wear sunscreen in front of my desk too now? Will the body cream include it?

        Too many questions. I'm going outside.

    Curious what people's thoughts here are on grounding as another benefit. Article talks about benefits of bacteria on the skin, but I'd say the other and maybe bigger benefit is discharge of electrical energy in our bodies to the ground. Which, can sounds weird depending. Some papers on the subject[0] talking about similar results as this article, almost implying that it's not the microbes, but grounding making the difference.

    I also got a $30 "grounding mat" that you plug into the ground part of electrical socket, and I dunno, it feels amazing to have skin touching it. I put it in bed and literally slept the best I have in years in the last two night, by far. Comments online generally are snake oil, but many others are first person accounts saying that for whatever reason, the grounding mat worked for them. (I have theories that the people who it does nothing for are those who already have an outlet. Like a dog where you're in nature and on walks, and also a dog can do the discharge for you). Other comments online are stories of how when the mat is plugged to ground, their cats love sitting on it, but if unplugged, the mats are ignored. That seems like some study that would be interesting at animal shelter, seeing if animals can tell and prefer.

    But anyway, wondering what others opinions on this topic are.

    Not just your hands.

    Walking barefoot, over all manner of surfaces, feels good, increases your connection to your surroundings, and slows you down.

    I've done it lots, both in the countryside and in the city. You have to watch out for spiky plants and fox shit in the country, and in the city you soon learn which surface textures require more care :-)

    > Those using the microbially-diverse soil saw an increase in the diversity of bacteria on their skin, and on the number of anti-inflammatory cytokines in their blood – while the other group didn't.

    That's really remarkable.

      Yeah, getting the immune system to tone down the responses is probably the best one can do for oneself health.

      Our body didn't get the memo that for the last 200 years water and food are clean now and bacteria is fought with antibiotics.

      Getting the immune system to not freak out at everything it detects via just touching grass is the best news I've read today.

    The mechanism is somewhat dubious imho - why would dirt selectively have beneficial bacteria that other environments don’t? I could come up with some just-so stories about how more “virulent” (haha) bacteria are the only ones to conquer our more sterile world but it’s just a plausible tale.

    I do subscribe to it myself but not out of evidence. It’s just vibes. Built my daughter a little dirt box with grass and edible herbs so when she would muck around at five to six months she could do it in there on the balcony of our San Francisco apartment and she enjoyed destroying the plants so at the worst she got some fun out of it.

      Ecosystems have niches for aggressive behavior against participants that reduce diversity. It's why you find higher concentrations of Lyme disease in new housing developments than you do in the deep woods: it's the activation of a defense mechanism (in this case it has to do with there being a higher proportion of competent hosts for the pathogen: mice, but in general evolution has myriad ways if implementing this pattern).

      If it's just you and one species of bacteria, you're closer to a circumstance that would call for the activation of such behavior than if diversity is high.

      So it's not that the bacteria are intrinsically good or bad, but that the different circumstances call for calm or aggressive behavior, and all your friends going missing cues aggressiveness in species who have evolved to fill that niche in the past.

    • dav_Oz 24 minutes ago
      To keep it simple:

      For one it's just competition. If you have regular contact to a diverse set of microorganisms chances are higher that they will keep each other populations in check. The dose makes the poison applies here too in some narrow sense.

      Additionally (or even mainly) our immune system always on guard (me/not me) gets to play around with the obvious stuff and not be overwhelmed or be "bored" but constantly trained/tamed. We have evolved to have constant contact to a diverse set of microorganisms which modulate our immune system e.g. through toll-like receptors.

      As an extreme case some people develop some natural immunity to the tetanus toxin through regular exposure to a extreme variety of microorganisms, obviously this isn't reliable nor a gamble remotely worth the risk.

    I heard the most ridiculous thing the other day:

    That GenZ and Gen Alpha have started doing this thing they call “private podcasting”. Where they invite a friend over and discuss topics like one of those podcasts where dudes just talk about stuff…but they don’t record it or post it anywhere.

    I was stunned. Is this generation really so socially starved by the attention parasites that human beings are starting to reinvent “hanging out” or “just having a conversation”.

    It’s so ridiculous I just refuse to believe this is how they actually think and this has to be some kind of rage bait. I pray that it’s rage bait because if it isn’t we failed our children badly.

    All that to say that I get similar vibes from the “grtting your hands dirty is actually good for you” thing. It just screams that entire generations of people have been stunted by helicopter parenting that this just seems like novel information. It seems we’ve completely abdicated our duty as parents and dumped our responsibility to educate our children onto profit seeking media companies. And that terrifies me.

        When you get older you've seen a lot of people who do things like that and are serious about it. Of course we haven't seen the podcast angle exactly but plenty of other things and it's common enough to make you cynical and so then you would fall for such jokes. assuming it is really joke which isn't clear

    • DangitBobby 22 minutes ago
      There's absolutely no reason to assume that getting your hands dirty would be "good for you". Playing outside and getting dirty is fun and is arguably great for enrichment and character building, but I think it would come as a surprise to just about anyone that it has health benefits.

      When I say "come as a surprise" I mean they would be unable to articulate the exact mechanisms behind the health benefits before being told what they are or that they exist. Liking a thing and presuming it must have health benefits aren't the same.

      If you're getting colds that often (and you're not immuno-compromised) then it might be worth getting checked out.

      I was getting sick constantly, and it turned out I had chronic sinusitis, and surgery made it much much better.

          If you have tonsilitis / tonsil stones, that means you have a biofilm there and it’s a very common place for that to happen.

          Regular mouthwash and even antibiotics won’t get rid of it, but a solution of vinegar, lemon juice and salt will.

        (To its credit, the Guardian makes place for long form articles that go more in-depth on known knowns and known unknowns.)

      Kids benefit from being kids and rolling around in the grass.

      In which cities are people favouring local parks over toilets?

      Parasites can actually help with allergies. I am loosely aware of various attempts at treating allergies using parasites.

      One of the approaches taken (under medical supervision) for kids with bad nut allergies is to gradually expose them to more of the allergen. Being able to survive a peanut or two without anaphylaxis is life-changing.

      This is like the dumbest take ever, do you think people go and take a shit on the park in big European cities?

      I live in Berlin and compared to most other European cities it’s a shit hole, but one thing I can tell you is the cleanliness and green nature of the public parks. Most of the time people actually care about the public parks (with exception of few)

      However, one thing to worry about is the tick bites or any other insect bites, but that’s part of the nature

          By your spelling of the word "germofoob" I get the impression that you're Dutch, am I correct? In that case I suspect that the "dozens of animals" you see "shitting on the same spot" are dogs in a small green area in a Dutch village or town. That is indeed not the spot to let your children play, fortunately the Netherlands does have plenty of "real nature" (or at least as real as anything can be in a man-made country) where they can play without being subjected to canine playdough.
