Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

Forest Bathing

By Mark Sisson
142 Comments

No claw-footed tub in the woods here. No Calgon fantasies for the frazzled mind or romantic shower under a waterfall. (Sorry to disappoint.) Think more science, less whimsy, but definite Primal roots. Forest bathing, as it has been dubbed, is actually a studied medical practice. In Japan, the research is spawning a whole new dimension of patient treatment called “forest therapy.”

Forests, like other wild settings, engage our senses in more subtle but evolutionarily familiar ways than our typical modern environments. Sounds in nature are quieter but more subtly layered. Our sight is more expansive. Our sense of touch, finer. Our smell, more acute. Surrounded by nature, our perception reorients to its default setting. As we’ve highlighted in the past, an increasing amount of research shows just how “natural” time in nature is for our physiological and psychological well-being. Exposure to green space offers protective factors against depression and anxiety and can help alleviate the symptoms of ADD. Instinctively, we know this and have likely experienced it. When we step outside our commotion-filled, asphalt-coated environments and truly inhabit a wild space, we’re more relaxed, more at peace. The mind finds quiet and the soul, release.

Yet, the research behind forest bathing takes all this a dramatic step further. Time in a wild setting, studies indicate, unleashes a powerful cascade of hormonal and cellular responses. Salivary cortisol, for example, dropped on average 13.4% when subjects simply looked at a forest setting for 20 minutes. Pulse rate, blood pressure and sympathetic nerve activity decreased as well. Even more remarkable is the significant – and lasting – impact on so called “natural killer” cells, powerful lymphocytes known to fight off infection and attack cancer growth. A longer three day trip in the forest with daily walks resulted in a 50% rise in NK activity as well as an increase in the number of NK cells! The forest exposure, researchers found, also resulted in increased anti-cancer protein expression. Tests further indicated a rise in the levels of intracellular granulysin, perforin, and granzymes A/B and a decrease in urinary adrenaline. What’s perhaps most surprising is this: subjects who participated in this series of forest bathing trips showed immune NK benefits that lasted more than a month. This finding, the researchers suggest, indicates the protective benefit of a monthly trip to the forest environment. (Have any weekend plans?) Yet, additional studies suggest that part of this immune boost is attributable to phytoncides, wood’s essential oils. Score on for aromatherapy. It’s interesting food for thought.

As a result of these studies, government entities in Japan are partnering with the medical industry to hold free health checkups at park areas and to create designations for “official” forest therapy sites. Finally, more companies are opting to include forest therapy in health care plans.

What I love about this research is the big picture implication. Without disparaging other daily efforts, let me say this: however ardent our efforts are to improve diet and exercise, a healthy life is so much more than the sum of a few prescribed parts. (Missing the forest through the trees, you might say….) The ultimate message I take from forest therapy is this: far from a social or cultural indulgence, living with and within the wild feeds the body as well as the soul. Encountering nature each day (in whatever way we can) offers a means of genuine nourishment and actualization. The benefits, however dramatic or obscure, are undeniable. The more I learn, the more amazed I am at the intricate interplay between our physical functioning and environmental influences. Ultimately, we’re primal animals down to the genes. We live best when we live in congruence with that fact. For me, the Primal Blueprint is about honing in on that essential experience. I’ve not only been healthier but happier and more at peace since choosing this lifestyle. The evolutionary model – the Primal logic – is there to be relished.

On that note, everybody, have a great weekend. Get out and enjoy! Thanks for reading.

That’s so interesting. I’d like to follow that research as it gets studied more.

It makes sense. I use to spend hours out in nature when I was a kid, and one of my favourite activities now is mountain biking – always out in the wilderness.

Mark,

Once again a great post; you continue to produce thoughtful topics that everyone who visits this site appreciates.

Now, away from the sentametalism.

This is inherently true. I find that every time I am where I cannot see, hear, smell or taste “civilization” everything is better. Time seems to slow down and you instinctively relax. Once again, excellent post; everyone should go for a hike this weekend regardless of the weather.

Just like vit. D or sunshine isn’t quite supplementation, but rather restoration, so to is going camping or hiking. The wilderness is our default.

I agree wholeheartedly. The more we are learning about our environment and our own physiology, the more we are realizing how utterly dependent we are on this intricate, interconnected world. Emerson makes a good point: “When I go into the garden with a spade, and dig a bed, I feel such an exhilaration and health that I discover that I have been defrauding myself all this time in letting others do for me what I should have done with my own hands.” -Ralph Waldo Emerson We need to make it a point to get into our backyard wilderness as often… Read more »

This is too awesome. Ever since I went primal 3 months ago I have fallen in love with nature. I want to spend so much more time outside and just go out in the wild. I went camping for the 4th of July and it was the first time in over 10 years!!!!!!!!!! I found out my relatives are going backpacking for one week… just 3 months ago I had zero interest in this… I would LOVE to go do this today!! Because of this I am living a much more healthy and vibrant life! Thanks Mark for inspiring me… Read more »

My parents just bought some lake front property north of our home city. I can’t wait to head up there again! It was so peaceful. Definitely restorative. I’m going to forward this post on to them! Another nudge in the primal direction.

Beautiful post. I live in the heart of ski country, and in the summer time we try to get out into the forest a few days a week. In July we hunt for wild alpine strawberries and raspberries. In late August and September, when the rains begin to hit, we hunt for wild mushrooms: chanterelles, boletes, oysters. It’s such a pleasure to be outside.

@Jenny: I live in Colo ski country too! For me unfortunately, that means 2-4 jobs just to stay afloat. So as soon as I get home from work, I take my pup down along Vasquez Creek or the Fraser River & watch him explore.
Just a couple blocks walk from my house I’m alongside the river & I feel miles away. I can xc ski the same trail in the winter – I like evening skis the best 🙂

Hannah

Just being in the forest in Northern Arizona, I definitely felt time slow down and was able to completely relax each day. It was amazing!

What I’m wondering is if the same principle holds true of oceans/beaches. Can people who do not have access to forested areas close by, but who have beaches instead still reap these benefits? I’d rather be in the mountains in a forest myself, but I did always find the beach at sunrise a very calming and almost magical place to be.

Cassandra
Cassandra
6 years 2 months ago

Hannah- I’m not so sure that the beach holds the same special quality that we can get from the forest. I happen to live right on the bay in Florida panhandle and it just doesn’t compare. Even though I have access to a very secluded part of the water (on the military base) it just doesn’t compare. Yet, it could be that I’m just a forest person. Some people that thrive on the ocean might feel differently.
Maybe it is the seclusion of the forest?

Jen

Perhaps it depends on your circumstances too — I don’t have regular access to a beach and because of this, I imagine, when I do get to a beach it is a tremendously relaxing and meaningful experience for me. Just hearing it helps.

So perhaps you’ve already met your “beach dosage” by sheer proximity, and vice versa?

Cassandra
Cassandra
6 years 2 months ago

Probably! Since I’m a native Floridian I’ve had enough of the beach. I crave the woods, even the Florida woods. I loved living in North Carolina because the woods are so much more fragrant, as well as the streams are cooler/clearer. (and no alligators or moccasins)

The forest has always been my escape. I used to live in rural VA and my family’s property was half wooded with a creek. It was heaven on earth. I spent most of my time there running, jumping over logs, poking crawdads with a stick (probably not the nicest thing to do in hindsight, but hey I was a kid). My boyfriend and I just got back from Peaks of Otter in the Blue Ridge Mountains. Talk about great! No cell phones, radios, tvs…just forest covered mountains to hike in and lots of deer everywhere. It was beautiful!

That. Is. So. Cool. I’ve always noticed my stress levels dropping when I get out of the city and into the green. I assumed it was just my slightly antisocial personality. Who knew it was a universal phenomenon? There’s no substitute for getting out there, at least for a solitudinarian like me. But wild spaces could be a bigger part of city planning than they currently are . . . imagine walking to work, for example, via wooded pedestrian paths. One could design buildings to bring the outdoors in. (School would be a vastly improved experience). Heck, we could make… Read more »

Wow, that was a great and timely post. I’ve noticed that ever since going primal I crave getting in the woods. I now dream of living in a small cabin in the woods and hunt, fish and grow my own food. I think this would truly be a great environment to raise healthy children. When it comes right down to it, we don’t need very much in life: nature, fresh air, food from nature, sunshine and water. All of this is free. I think I’ll try to escape for a couple of days in nature very soon with very basic… Read more »

I just spent 4 days in the deep woods of Northern Wisconsin, so I know exactly what you mean by restorative. Time slows down when your hiking through the woods or canoeing down a little river.

I like the sounds (or lack of sounds) the best while walking in the woods.

That’s one of the things i love about living in New Hampshire–we’re mostly forest. There are even protected areas really close by where you can go for miles without coming across anything man-made. It’s great.

Yep, great post, just spent 9 days camping as I cycled from one end of the UK to the other, just wonderful. I run/walk through wooded trails almost every day and it always gives a sense of peace, the idea it could be used as a recognised therapy is very interesting, but so logical, as is everything about the Primal lifestyle.

Have a great weekend

Beautiful post, and I’ve found the more I get outside in nature, the happier, more relaxed and connected I feel.

I’m lucky to live in an area with some nicely wooded parks and I’ve got three furry running/walking buddies that encourage me to get out every day, at least once.

This concept is very popular in Norway (and I would guess in other Scandinavian countries), too, though I’ve not heard it described with the same term.

One of my Bergen, Norwegian nephews goes to a public elementary school (based on the Rudolph Steiner philosophies) that emphasizes spending time in nature as an integral part of early childhood education, regardless of the weather (there’s a Norwegian saying – there’s no such thing as bad weather, only bad clothes). They take the kids into the forest as much as possible for entire school days, even multiple-night overnight stays, too.

Ditto all the comments on the benefits of time in nature. One aspect I did not see discussed was the benefit of being grounded (literally, in the electrical sense) by spending time barefoot in contact with the earth (not insulated by shoes or buildings….). Our modern lifestyle represents a major departure from ancestral patterns where our bodies were in constant contact with the earth and exchanging electrical energy. I came across this recently (in a rather unexpected way as a link on the website of Jeff Spencer, DC, Lance Armstrong’s chiropractor), see the following for more info (I have no… Read more »

love the forest! luckily, i live on a property that backs (or fronts if you look at it from hwy sense) a national forest. and 80% of my property is forest anyways – 25 acres worth of a creek, and high mountain forest with pines, oak, and a lot of dreaded poison oak i seem to have had constantly for 8 months straight now 🙁

try rubbing the inside of a banana on the rashes. Keep a thick application of it on there through the day. It will help dry up the blisters and calm the itching. I had it so much as a kid I don’t have a reaction to it anymore!

Growing up, my dad and I would go hiking in the high sierras every summer. Just me and dad, disappearing into some of the most beautiful spaces on earth. That was about 30 years ago I suppose and I can still remember so much of it.

If only I could go back in time and do it all over again…

It’s really a bummer that we are so overpopulated that most of the time we can’t even get away from people when heading 4-5 hours deep into the woods. Someone else always has the same idea…. I could literally live in the woods, in a tent type shelter and never see another soul again…that would be heaven for me. BUT…my husband loves his bathtub, A/C, couch and TV so much he’d never go for it. Never understood how people LOVE living in cities with a gazillion other people, all that noise and stink…yuck.

Living in the cities maybe takes a certain type of person, but the variety and constant stimulation it offers can be very stimulating and life-affirming. It always was for me. Every day was a new start and posed the opportunity to do or be something new. There is something about the claustrophobia of a small town that probably helped lead Grok to that early grave.

Great post! I like to use stargazing as a natural retreat. I think Grok probably looked up at the stars for hours on end.
Before cities and towns began spraying their lights all over the night sky rendering all but the very brightest objects visible to city dwellers, the night sky was pretty cool.
If you have ever been somewhere far away from city lights, you know what I mean. I live in a big city suburb but still manage well with binoculars or a small telescope. It’s very relaxing.

We just bought a little place on 2.5 acres of wooded hillside. I started reading about Primal/Paleo lifestyle shortly after. Hmmm…I’m thinking there’s a connection.

There’s nothing like sitting on the porch early in the morning watching the deer. And since there is no TV, no internet, no phone – we rise with the sun and go to sleep at dark. Pure heaven.

Just one question: does a hot tub on the deck count as forest bathing? LOL

I grow numerous flowers and some vegetables which take up most of my yard time but my favorite place in our garden is a path through a wild, secluded part of our property with tall trees.

I do have to say though, when I am in a forested mountain, eventually I say…get me out of these trees! I need my open spaces and sky scapes too.

My bicycle club rides all over the Minneapolis area…not me…I always go down to a twenty-mile trail that is totally surrounded by farmland and woods…now I have a perfect excuse for being so terribly “antisocial”! After taking care of hundreds of passengers on my four and five-day trips, I just need the peace and quiet! Viva la forests!

Nature is the best place to be. I recently blogged about going to my parent’s house and the effect it had on me (we have a farm and lot of green fields and woods around our house).

I grew up in the middle-of-nowhere part of Minnesota (which is a middle-of-nowhere state as it is).

I wound up spending plenty of time in the woods. It was right outside my door and I did plenty of fishing and hunting as well.

There definitely is something therapeutic about being as far away from civilization as possible. There’s a lot going on out there that you wouldn’t realize until you start exploring!

You have summed it up. I just moved from a city in Florida, where I was starving for green, to the Pacific NW where there is a forest literally outside my door, and I walk through it every day. I also seek out other forests to walk through. I am so happy in the forest I think I will burst out of my skin. Ditto for the kiddos. They love it too! The sights, smells, and sounds are like heaven. Love it!

This is so true Mark. Great post. I might eat Primal and I try to exercise Primal but I remember in my younger years how being in a forest setting made me feel alive and healthy. Now I am forced to spend most of my time indoors with very little exposure to nature and my health has been declining rapidly (physically and emotionally) over the last 10 years. I often think about how I miss the trees and nature I was surrounded with in my youth.

This post really reminds me to get outdoors more and get into a nice serene forest. I used to love walking or riding my bike through a local forest when I was a kid. It was so calming. I don’t do it enough and I think getting out and into the forest will instantly bring back some wonderful childhood memories.

I moved from Brooklyn, NYC to a small alpine town and I hate it. I thought it would grow on me but it hasn’t. Nature might be natural but it doesn’t mean we all “naturally” love it. I come alive and thrive in an urban space. If reliable research says I should do go stagger around a forest regularly then maybe I’ll try a little harder to do it but I imagine my disdain for the practice might taint the healthful benefits.

Great post Mark..You should start reading the works of ET Seton and George Sears (AKA Nessmuk) if you have not already. I just spent almost a week camping (in a tent of course) on the ocean with my sons – It was the Grok Lifestyle all the way. Outdoor life IS the HEALTHIEST lifestyle.
