'Forest Bathing' Considered Healthful
Hugh Pickens writes "The NY Times reports that although allergies and the promise of air-conditioning tend to drive people indoors at this time of year, when people spend time in more natural surroundings — forests, parks, and other places with plenty of trees — they experience increased immune function. A study of 280 healthy people in Japan, where visiting nature parks for therapeutic effect has become a popular practice called 'Shinrin-yoku,' or 'forest bathing,' found that being among plants produced 'lower concentrations of cortisol, lower pulse rate, and lower blood pressure,' among other things. Another study in 2007 showed that men who took two-hour walks in a forest over two days had a 50-percent spike in levels of natural killer cells, and a third study found an increase in white blood cells that lasted for a week in women exposed to phytoncides in forest air."
Am I the only one that read the title as "'Forest Bathing' Considered Harmful"?
Increasing exposure to foreign elements leads to a stronger immune system? ASTOUNDING.
I think it is astounding. I just shows how little we understand about the immune system still.
People who get off their ass and go outside are healthier than those who don't.
I want to shoot the messenger!
I grew up on a farm, and the only people who had air conditioning were living in town. I didn't even know what allergies were; none of my friends or anyone in their family had them, until I started making friends with people who lived in town and had air conditioning and super clean houses. THEY had allergies.
Great outdoors good for you. News at 11. What would we do without science?
I assume this would be bad if you have an autoimmune disorder.
In Reverse? Trees helping keep us alive? They should be trying to kill us.
In the Midwest, our forests are just plain nasty... I would be surprised if the Japanese have anything close to ragweed. My family is originally from up north, so we are all allergic to this, but correlation does not blah blah blah
.I wonder if they have to worry about ticks, with all the fun stuff they carry, as well over there on that island. I'm thinking the plant life just might be different. I grew up playing in a greenbelt full of poison ivy and ragweed, along with scrub trees that put off that layer of pollen that will cover your car, so after RTA, I can't say which side of the coin I prefer I'm afraid.
I've actually been planning a backpacking/primitive camping trip with a buddy of mine for a while now, which was prompted in part by a random feeling of being tired of all the comforts we take for granted, as well as realizing how out of touch the majority of people are (myself included) with nature and the associated skills that come with it (the ones that many of our Dads may have taught us, and we've since forgotten). I'm glad to know that the trip will have these other benefits too.
Not really, I remember reading similar (but more generic) findings nearly 10 years ago - in general, more exposure to foreign things tends to lead to a stronger immune system. This follows pretty directly from that, I think.

Vitamin D is a very potent vitamin which the body only can produce in direct exposure of sunlight and is stored in the fat of the body.
It also exist in a small range of foods.
The problem is when you don't get any exposure of sunlight and you don't eat any food which contain vitamin D.
Vitamin D deficiency has been seen to result in a wide range of consequences such as Osteomalacia, Rickets, multiple sclerosis, rheumatoid arthritis, juvenile diabetes, Parkinson's, Alzheimer's disease, depression and low immune defence.

As you all know old people mostly cover up their body to not get cold, which in result leads to very little sun exposure.
I am not saying it is an universal cure, but I wonder if it can have a connection??
Scientific American recently did an article about the soil bacteria mycobacterium vaccae, which you're likely to be exposed to in a forest. Apparently it gives mice a temporary, but fairly large boost in maze solving ability. No clue if it applies to humans as well, but there's certainly no harm in getting out of the city every once in a while.
I used to get allergies (hay fever) all the time. I worked at a scout camp where we slept in canvas tents, so we were outside 100% of the time. The first year I worked there I benadryl-ed myself up all the time until I ran out, and the trading post ran out. I had to suffer with only facial tissues... but after a day they went away. And didn't come back for 2 weeks. 2 weeks later, I had allergies, but this time did not medicate. Then I went another 2 weeks... so I just learned to suffer a day and have 2 weeks of unmedicated joy.
Fast forward to 20 years later... I still have allergies, but I bought a convertible. I like the air. Even on these 100degree days, it is top down. My hay fever has virtually been eliminated.. I *might(* get something in the spring, but this past spring I made it through without any problems.
I think that in the absence of stimulus, the body cranks up the sensitivity to the point that it goes crazy. This seems to be confirmed by Helminthic therapy, where you purposely infect yourself with parasites (of a specific species with low risk) and these buggers help manage your immune response. But this helminthic therapy advocates say it treats "diseases of civilization" like asthma, which is never found in the undeveloped world.
So spending time outdoors seems to be a help to reconsult the environment that the body functions best in.

What this article really seems to be saying is that living in towns and cities is harmful and that hanging out in parks and forests temporarily alleviates the symptoms.
While going for a walk in the woods for its own sake is great, it's hard to convince the family and friends, sometimes, that what they really want to do is put down the remote and go for a long nature hike. This is where geocaching is so great; the kids think of it as "searching for treasure", and my friends have taken up the various challenges with excitement ("how are we going to cross the river?" "How are we going to get down from this ciff", etc. Whereas I could never convince them to go before, once there's a challenge, something to find, out there, they're all for it.
My personal satisfaction came from the fact that two of my friends were so angry about being left behind, or just struggling to keep up in general, that they both quit smoking.

Your unscientific anecdote is negated by my own equally unscientific anecdote:
I grew up in a small farming village, a tiny population in a state with one of the lowest levels of air pollution, with no air conditioning whatsoever. I had absolutely terrible allergies, up to and including asthma, eyes glued shut due to "sleep" (secretions), and the need for serious medicine that didn't really help much.
The best thing I ever did was move to a city, get air conditioning, and stay the fuck away from the grass, trees, and other foliage that made my life a living hell. I didn't get allergies from living in the city as you so erroneously imply, I got them from being exposed to pollen in the first place, and short of paving the planet, a large city with relatively little green space is in my experience an ideal environment for those who suffer from Hay Fever, pollution notwithstanding.

My great-grandmother grew up in a farming village. There was a group of people who would always get colds around harvest-time; they were widely suspected of being malingerers, but she realized much later that they just had seasonal allergies.
This article assumes of course, that one does not become subject to a bear attack.
Sometimes the light at the end of the tunnel is the headlight of an oncoming train.
The article by Li et al doesn't show that the forest has anything to do with the change in NK activity. They base their claim that NK activity increased after a forest walk by comparing NK activity to a baseline obtained from the same subjects on a normal working day. Why couldn't the difference have been due to the exercise itself? They should've had a control group of folks taking a city walk, and a third group using treadmills to exercise.

We've been camping for a week and my greased Yoda doll is still there.
Trolling is a art,
I've been going outside, cycling, walking & climbing trees since I was a whoosh in my daddies'... I have spent years of holidays in the German, Austrian and French Alps just enjoying nature and I still find time to code and create webbies (F**K the social media sites though, they reay s**k a**e). The benefits I get from the great outdoors are legion (apart from that snake that one time...) Is it at all possible that one day scientists could study themselves and their grants and come to a determination that they will write s**t for money and "state the bleedin' obvious"?

Eastern Europe - Outdoor Active Lifestyle
I grew up in a very polluted coal mining and burning part of eastern Europe and all of us kids spend their entire time outside, except for a few hours of sleeping, parents calling us to come in for dinner, which we would promptly eat and then leave again to play with friends, and the few hours a day that we would be required to be in school, but even then we would have two breaks and lunch which we would spend outside playing. Even during cold and rainy days we would be outside doing stuff with out friends, meeting up under various try spots that we knew outside. There was no air conditioning and I didn't see anyone suffering from any type of allergies or asthma that I remember but I do remember a few sickly kids that would spend their time indoors.
Our apartment complex in the big city was covered with busy roads and tons cars and commercial traffic, we even had an actual a coal burning plant which would create the hot water for the entire housing compound right in the middle of the apartment complex and we even occasionally venture next to it to play war around there among the dumped burned off toxic leftover coke byproduct of coal burning. However, at the same time our apartment complex was next to a huge park, a farm, and with tons of trees littering the paths between the apartment buildings and throughout the city between every single street. You could walk large parts of the city during light rain and hardly get any wet just by walking under the trees!
During each 2-month Summer vacation and 3-week or longer Winter vacation my mother would always arrange for me to go on the company sponsored camping and I would then spend weeks at a time away in the mountain and forest areas playing outdoors even more with kids and then go on hikes and outdoor tent camping events on top of being outside. We never did any indoor activities unless it was raining and even then we would find excuses to run outside and get soaking we just for fun. I spend more time getting dirty among nature as a kid then I care to remember.
United States - Sedentary Indoor Lifestyle
When I came to the United States later I found that most kids stayed in-doors most of the time and hardly went outside. Being an immigrant child I kept to my roots and hung out with my own kid friends spending our entire summers outside in the parks and going away on lake and camping trips on the weekends with family. The Summer and Winter camps here turned out to cost a lot more money and since they were not sponsored by my mother's work I couldn't afford to go. I tried to spend a much time as possible outside in the summer playing basketball and football with whatever friends were left in the city but since many of them went away I became sedentary and gained weight, then started spending a lot more time at the computer than I should have which in turn decreased my ability to go outside and enjoy myself.
Now that I move out to another part of the country where there is a lot more outdoor activities I am getting myself involved in outdoor type events so that I can get back to being in nature. Airsoft has become my newest outdoor hobby and I just love the idea of literally crawling through thick woods with a replica gun just to shoot at people and have fun outside while hugging and blending in with the nature. I came out filthy as a dog from that weekend excursion but I was hooked!
When I have kids I will guarantee that they spend their entire time outside doing activities and go away every Summer and Winter vacation to camps, no matter what I have to sacrifice for myself to afford the cost. I want my kids to be familiar with nature and be comfortable being in the woods like I was.
Yes, just like "winningest", "mostest" and "druther" - it reminds me of my childhood, when I was 4 or 5 years old.
Todd: I hope it proves as delicious as the farmers that grew them
Nobody mentions that this study's finding must also mean that spending time *away* from natural environments is remarkably *unhealthy*.
And I've known this all my life.
I hope this will make up for all the GOTOs I've been using.
I live in an area (Yellowstone National Park) that suffers from widespread Giardia parasites in the water. Drinking infected water can be a ticket to a few days of intestinal hell. I think infection only occurs by ingesting, but bathing in infected water does give you a lot of opportunities to ingest those nasty things.
All this article affirms is that reducing chronic stress makes people healthier.
Stress evolved to be an acute reaction to a specific stimuli. When your stress reaction becomes chronic your health suffers.
Ergo anything that reduces your stress response will improve your health.
I expect that people who had some type of forest phobia would not receive the same benefit.
"Another study in 2007 showed that men who took two-hour walks in a forest over two days had a 50-percent spike in levels of natural killer cells, and a third study found an increase in white blood cells that lasted for a week in women exposed to phytoncides in forest air."
Um, so these walks resulted in increases in 'natural killer cells', increase in white blood cells, and this is good?
I thought increases in white blood cell count would be a sign of an immune response. As in a reaction to a sensed infection or harmful object/etc. This is good?
Mind you, I always *do* feel better wieh I have a chance to walk in the woods. But I'm highly allergic to white pine pollen, and have been since before I was 5, and before I was exposed to air conditioning. It's genetic for me. Same with some other plants. But in the main, I'm not allergic to the woods, beyond breaking out in welts if I roll around in the meadow grass or kneel down in pine needles, or push my way through the brush and scratch my skin on any of dozens of species of leaves.
And I still love the woods, and go out any chance I get. In Arizona, in the high desert, this is not often.
Yeah, walks in the woods result in increased white blood cell counts. That must be good for you, it's all natural!
deleting the extra space after periods so i can stay relevant, yeah.
I just shows how little we understand about the immune system still.
We understand it sufficiently to know that gets better as it responds to potential threats. Consider vaccines, for example.
We also know that humans didn't evolve in air-conditioned rooms, but rather outdoors, in forests and savannas.
As a person named Forest, I agree completely. I imagine most people around me would agree.
There is a discipline called "medical anthropology" which studies the traditional medicine of various cultures and how it interacts with modern medicine. EVERY culture still more or less has its folk medicine: Examples include British interest in colonics (read about Kellog's push to eat grain in the morning), the French and their livers, Germans and their hearts, Indians and meditation, Chinese and acupuncture and so on. And scientists from each culture have conducted medical studies their favorite aspect of folk medicine. To me, most of these studies are inconclusive. Thatis, some benefits, little harm, and not the cure-all promoters were seeking.
After living a year in the jungle I returned to Anchorage, Alaska in October just as the ground was starting to freeze. I was feeling a little down and the feeling didn't go away as the snow came, the temps dropped and the daylight waned. In February I looked up sometime around midday and proclaimed "I miss dirt". I know I need to be out there. I feel so much better when I am in the field and afterwards as well. Of course I may be a geek, tech savvy or whatnot, but I am no city boy. I grew up in the redwoods, even lived in a teepee when I was a kid (my dad never owned a computer in his life) and I am more comfortable sitting in the bush then I am sitting at my computer. Life forced my hand so I am forced to do the tech work for my company, but I still get to do the field work too and I swear it gets me a little high (not just the work, the being outside), it lasts for weeks. Sometimes if there is no field work to be done I will drive south until I get to the ocean and find a place with no snow and go lay in the woods on the dirt. Just to be clear, I am no hippy-dippy freak.

History is not as simple as that. Humans have a very complex history of migration and evolution over the last 200,000 years or so.
The world does not neatly divide into "forest people" "mountain people" "ocean people" "desert people" "plains people" that are "evolved to live in that environment" etc. outside of neatly divided computer games.
Agreed that our ancestors lived outdoors more than us but they moved around a more complex set of environments than just forests. And 2000 years ago, you could find a fair number of urban Europeans who never lived outside of a town or city for their whole lives. Julius Caesar might be upset to hear you describing Rome as a forest....
How do you know it was unnecessary and he wasn't contracting the sentence "Likely the one is crawling up into your urethra or anus"? Now, I'm not sure why he'd be suggesting Neo would do such a thing, but it's possible that's what he meant.
This is nothing to do with increased exposure to foreign elements building up a stronger immune system. If you want that, the best place to get it is staying in your air conditioned office and sharing everyone else's germs. This is about time spent in a more natural environment promoting a healthy mental state, which in turn helps the body fight off illness and counters the effects of disease. What illnesses are you expecting to be exposed to in a forest that will boost your immune system? Illnesses that affect humans tend to be prevalent in areas more densely populated by humans, not in the middle of nowhere. It might, however, help reduce instances of allergies (pollen exposure, etc) - since I moved to the city I seem to suffer greater and longer bouts of hayfever each year, something I never once experienced as a child living in a semi-rural area.
You grew up as a NORMAL kid, as did I. This coccooned-child thing in the U.S. has only been around for the last 20-25 years, and I agree entirely, it is a bad thing. Kids need to go outside, get dirty, and learn to create their own entertainment, instead of having it thrust upon them.
And on that note, I recall research about how kids learn: seems learning isn't absorbed and processed during the "work" periods, but rather only during the "idle" periods, when kids are just being kids. So this "go outside, root in the mud, and generally do nothing useful" is not useless at all, but rather quite necessary to normal learning.
Likely just as true for adults, tho often ignored (maybe that explains why adults have a harder time learning than kids do??) I've found for myself that for every hour doing something Useful, I need an hour of decompression -- go outside and pull weeds, or watch ants, or do something equally "natural" and nominally useless.

This doesn't come as a surprise for us way up north in scandinavia. Regular, year-around, baths in forest lakes and the baltic sea are common treats here. Diving into cold water really takes the every-day-stress out of you. If you ever get the chance to do this, I suggest you take it. Enjoy!

"AFAIK exersize has never been shown to boost the immune system (someone please correct me if I'm wrong)."
You're sort of wrong. Moderate exercise boosts the immune system, go over 90 minutes and it's temporarily weakened. Maybe.
Never let a lack of data get in the way of a good rant.
not only that, but the social skills that come with interactions. I'm constantly amazed at how complex the "rules" get for their games. Considering they had to invent them, compromise, figure out "teams", police themselves, follow them and work out differences, it really does involve a lot of "work". Much better than turning out to be a pasty white, allergic social retard (sorry /.)

Here in Germany there is a new kind of kindergarten gaining momentum. It's called "Waldkindergarten" which literally means "forest kindergarten". They just put a small trailer or so somewhere into a forest which is used as a base station to store things, clothing etc. The actual kindergarten though is the forest. The children are outside all day long (with clothing according to the weather), playing and learning things. Almost all children immediately adopt to that. Rain, snow, cold, sun, whatever. Great idea and even much cheaper to put in service.
