Get Dirty to Get Joy- Bacteria in Soil Acts as Antidepressant

Get Dirty to Get Joy- Bacteria in Soil Acts as Antidepressant
A bacteria found in soil called Mycobacterium has been found to effect the same neurons as Prozac, offering people a natural lift in mood. This is just one more great reason to get out in the garden and grow your own foods. Not a green thumb? Just spending time in areas with rich soil will allow you to breath in these great benefits. – Intelligentactile

Imagine: You’re feeling so depressed that you visit your doctor and request a prescription for a mood elevator. Instead of writing you a prescription for Prozac or a similar antidepressant, she advises you to get dirty. While you consider changing doctors, she describes how getting dirty changes your brain chemistry. The microbes in dirt, she says, tweak the same neurons that are stimulated by Prozac. Your options, she explains, are an expensive drug plus its possible side effects, or gardening, yard work, or a romp in the park. Your doctor, it turns out, hasn’t gone round the bend. She is actually up-to-date on the latest scientific findings about how the natural environment affects our brain function.

The dirt-and-Prozac connection surfaced a couple of years ago from Dr. Chris Lowry and his colleagues at the University of Bristol and University College London. They exposed lung cancer patients to a common, inoffensive microbe called Mycobacterium vaccae, found in soil. The patients unexpectedly reported increases in their quality of life, including a brighter mood. The researchers wondered if this effect was caused by stimulation of neurons in the patients’ brains that produce serotonin, a feel-good chemical.

Taking the next step, they broke up M. vaccae into fragments with sound waves and injected them into the windpipes of anesthetized mice. When compared to controls, the mice exposed to M. vaccae had more activity in serotonin-producing neurons and higher levels of serotonin in several areas of the brain. “[The bacteria] had the exact same effect as antidepressant drugs,” Dr. Lowry said. The scientists said that one might derive dirt’s benefit directly by rooting around in a vegetable garden, or by eating lettuce or carrots picked from that garden. Popular media ran with the findings. ”Is Dirt the New Prozac?” asked Discover magazine.

The dirt-and-Prozac connection fits with a recent idea in medicine called the “hygiene hypothesis.” According to this concept, exposure early in life to the bacteria, fungi, and viruses found in common, everyday dirt is necessary to stimulate our immune system. When children are exposed to the stew of microbes in dirt, their immune systems become stronger. The immune system also learns to ignore substances like pollen or the dandruff of pets, which can trigger asthma and allergies. Researchers have shown, for example, that kids who grow up in dirty environments such as farms have a lower incidence of infections, asthma, allergies, and eczema later in life, compared to kids raised in urban environments in which parents try to keep them squeaky clean.

For a century and a half we have waged merciless war on filth through public health measures such as public sanitation systems and water purification programs. These developments have been enormously successful. The increase in lifespan in modern societies is due largely to the reduction of death rates from diseases such as typhoid and cholera, which in nineteenth-century America were called “filth diseases.”

We have to wonder, however, if we have gone too far in our obsession with hygiene. Throughout our evolutionary history our ancestors lived in intimate contact with dirt, and its influence, we now see, was not all bad. We evolved in the outdoors, and we are beginning to glimpse the price we are paying for shutting ourselves off from nature.

Don’t worry. Nobody is suggesting that we never bathe or clean our bathrooms. Neither is it necessary to inject M. vaccae into our windpipe. If we merely go for a walk in the woods, grub around in our vegetable garden, or weed our flowerbeds, we get a dose of the good bugs simply by inhaling.

“Nature deficiency disorder” has been proposed as a term for the problems we create when we build a wall between the natural world and ourselves. I am highly susceptible to this malady. When I spend too much time indoors, I become increasingly moody and morose. There’s only one cure: take a hike, go camping, or root around in my veggie garden. These activities are more than a hobby; they have become an essential part of my life and an important element in my personal health plan.

What about kids? Not so long ago, play and getting dirty were pretty much the same thing — frolicking in a sand box, making mud pies, romping in parks. Now many parents are horrified by dirty play. Keeping kids spotless and unsoiled, however, may be setting them up for trouble later on, because without exposure to nature’s medley of microbes our kids can grow up with confused, weak immune systems. Can we rethink the prohibition on dirty play for the sake of our children’s health?

Antidepressant medication can sometimes be a treatment of choice. It can work wonders, and in some instances can be life-saving. But if your doctor advises you to get dirty instead of taking a pill to perk up your mood, don’t look at her strangely. Pride yourself on having a physician who is on the cutting edge.

Think of it this way: Have you ever seen an unhappy earthworm?

Skills Showcase: How to Brain Tan Buckskins

  • Have you ever wondered “how did the natives make such beautiful and soft leather without all the chemicals?”  We will attempt to explain the process so you can try it at home.  We are assuming that you already posses the animals skin.

1. Fleshing- with a rib bone, leg bone or hardwood stick that has been carved and burnished, push all the flesh off of the hide. you need a smooth beam (log).  You can either lean it against a tree pinning the hide with the beam or lay it across the log pinning it with your body.

2. Dehair– this can be done on or off the rack.

  • Off the rack –  Soak the hide in a stream till the hair starts to slip on the neck then use the same technique as fleshing.
    • On the rack- Poke holes every 4 inches around the edge of the hide.  Make sure the holes are 1/2 inch in from the edge running parallel to the edge about 1/2 in length.  Stretch the hide tight enough using string through the holes and pulling the hide evenly so that is can dry out on the rack without any wrinkles.
    • once dry use a bone or stone scraper to remove the hair.  which leads into the next step

3.  Scrape or remove the grain – when the hair is gone you will see a peppery look to the hide.  This is hair follicles embedded in the epidermis (outer) layer of the skin.  This layer must be removed.

Scrape carefully till the dermis layer is exposed.  The skill will become fluffy like suede.  It is best to work in small sections or blocks 4 to 6 inches square.

On your first hide you will probably scrape so lightly that this will take hours or scrape so hard that you poke holes through it.  Either way, don’t give up, it’s all part of the learning process.  you can always tan another hide, right.

Be careful along the belly and inner thigh areas.  They tend to be the thinnest and easiest to bust through.

4. Membrane- once the dermis layer is reached turn the hide over and scrape the flesh side till it is fluffy as well.  This side doesn’t take as much scraping.  In both steps 3 and 4 work the center of the hide first and then do the edges.  I like to keep a two-inch buffer around holes and the edges, then come back and scrape those areas last.

5. Brain- take the animal brain(if you have it) and smash it up in warm water. about 1/2 gallon to 1 gallon is all you need.  If you don’t have any brains you can substitute with egg yolks (not the whites).  DON’T USE HOT WATER.

Soak your hide in the solution either by taking the hide off the rack and placing it in a container with the solution or use  something to apply the solution saturating the hide while it is racked.

6. Softening- once the hide is saturated and let sit overnight without drying out, you can begin to soften the hide.  the fibers in the dermis layer must be kept moving until the hide is completely dry.  Do this by re racking the hide ( if not still on the rack) and using a stick with a rounded smooth end.

Take the smooth end of the stick and push on the hide while sliding the stick across the surface of the hide.  When the hide is no longer cool to the touch then it should be dry.   You can soften off the rack as well but it doesn’t turn out as flat and smooth as one softened on a rack.

You should have a milky white soft and fluffy skin in your hands.  be careful not to get it wet or it will turn back into rawhide.

7. Smoking- First make the hides into a bag by either sewing or gluing the edges together,  Leave an opening about 6 inches around  in the neck area.  While sewing  or gluing the bag together, have a hardwood fire lit and burning.

Dig a hole about 6 -8 inches across and 1 foot deep.  Hang the hide bag upside down over the hole. Connect a skirt made of cloth or other hides to the neck.

Add hot coals only, no burning sticks to the hole.  Break up the punky wood and cover the coals

Stake or use rocks to hold the skirt down around the hole to funnel smoke into the bag.  Make sure that the punky wood does not flame up.  Add punky wood as needed to keep a heavy smoke generated.

Once the outside of the bags starts to change color (about 1 hour) turn the hide inside out and repeat. The longer you smoke the hide on each side the darker the color will be.  2 hours on each side turns out a nice dark color.

Once the second side is complete you can wash the hide and let it dry and you will have a beautiful piece of buckskin.  This process can be completed in just a couple of days.

We hope this post was helpful.  If you are a beginner seeking hands-on experience in hide tanning or other skills, please check out our Adult Workshops

Wilderness Skills Showcase – Shelter (Debris Huts)

Learning how to build a shelter is one of the most engaging skills for instructors and students alike. Few other skills under the “primitives” umbrella get you as much bang for your buck. The skill of constructing (and/or finding) a safe, dry, warm place to retreat should be a top priority for everyone, ranging from those who are very focused on emergency survival scenarios where the idea is to live through the immediate future and get back to civilization (protection from the elements is generally one of the first issues you want address) to those who are interested in longer-term wilderness living situations.

Volumes could be written about different styles of shelter, materials, etc. One of the most basic and frequently taught methods is a simple debris hut, which is essentially a framework of branches that can be covered and filled with layers of debris that shingle (on the outside) and insulate (on the inside). There are dozens of ways to tweak and customize this type of shelter, and it’s the type of shelter we teach most often. So for kids, what are some of the benefits to learning how to build shelter?

For one thing, it’s a skill that allows a wide range of ages and skill levels to tap into their powers of creativity and imagination. There’s a reason almost all kids love to build forts, and they’re all the better for doing it outside in the fresh air and sunshine instead of indoors where their poor little developing brains are bathing in the ambient noise of television commercials and the harmful compounds off-gassing from paints, carpet, and couch cushions. Building a shelter requires cognitive skills like visualizing, executing plans, problem-solving, and overcoming setbacks. Debris huts are relatively free-form, too. The sky is the limit in terms of finding new ways to fit the pieces together, find new ways to utilize the materials you actually have at hand in different situations, or add features like a lowered entryway that will keep your warm body heat trapped in the inner chamber, a fence of sticks at the base of your walls to trap slumping layers of leaves, or a lean-to/heat shield outside to protect a fire if you have one. The building blocks for shelter are accessible to almost everyone, with little skill or modification necessary. Sticks, leaves, and bark are laying everywhere at your feet, just waiting for kids to imagine and create things out of them, and shelter really helps people of all ages re-establish a creative connection to their environment.

Building shelter can also be a real ice-breaker for students who aren’t as comfortable in natural settings. Some kids are even squeamish about simply sitting in leaf litter or on the ground when they first find themselves in the great outdoors. Next thing you know, they’re having a blast working in teams to rake up giant piles of leaves (and jump into them), gather sticks and branches, and peel up dead bark in sheets. The trick is to take what would normally be a chore, and transform it into play. It can be a social activity where everyone collaborates, building up each other’s strengths and compensating for their weaknesses. Making a shelter really helps people get over any hang-ups and break down any barriers they see between themselves and the natural world, because before too long you’re covered with nature in the form of “dirt” and leaf duff, and, lo and behold, it’s fun. According to the hygeine hypothesis, getting all this crud on you is actually beneficial to your health and immune function, and missing out of the experience of slathering yourself in benign and beneficial symbionts (bacteria and other) can be detrimental.

At the end of the day, few things can make you feel as “at home” in nature as…well, making a home in nature. It bolsters confidence, beefs up critical thinking skills, makes people more aware of the utility and presence of natural materials around them, makes them more effective and clever at using those natural materials, gives people a sense of agency and capability in their environment, and can bring them together for a darn good time.

Are Those Mangos? No, its a Paw Paw!

pawpawPaw paw trees produce the largest native fruit in North America, and as you can see in the photo below they look sort of like small green mangoes. During this time of year the fruits are ripening, and the kids in our Homeschool Naturalist programs are loving them! In addition, paw paw trees bless us with bark that makes effective cordage and wood that is most useful in friction fire kits. Identification of edible and useful plants is one of many skills your kids could be learning with us here at Ancestral Knowledge! The next Homeschool Naturalist Program starts Oct. 31st, and sessions run for 6 weeks.

Summer Camp Fun!!! WOOT!!!

Well it’s that time of the year we have all been waiting for!  That’s right it’s time for our summer overnight camps! We are having a blast with a great group of kids.  So far they have learned how to gather the proper sized firewood, build the proper structure, ignite it using only one match, and how to use the fire to cook their food.  The campers have also learned how to safely and properly use a knife, carved their very own rabbit stick, and learned how to move silently through the forest. Today they will start making friction fire kits (bow drill) and learning how to make basic stone tools.   Afterwards we are going fishing and camping out under the stars along the Shenandoah River where they will use fire as a tool to burn and scrape wood to make eating utensils.  Oh yeah, We can’t forget the scout log (pictured above).  Well that’s a secret but I am sure your kids will tell you all about it when the return home stronger, more confident, and full of stories of adventure!

Travel Without Time or Destination!

So many people talk about wanting to connect with nature, achieving oneness, or grounding themselves. There are so many programs and organizations advertising nature connection (we sure have them). I don’t want to be the bearer of bad news, but in my opinion no program or workshop can make that happen, it’s too personal of a journey.  However, I do believe that workshops and programs can lead you to the trail head, point you in a direction, or give you the vehicle to get you there, but there is a catch!  It definitely isn’t as easy as a click of a mouse and it won’t happen overnight!  I can say, learning wilderness skills and increasing my awareness have been part of the best years of my life! When I experienced the feeling of oneness and connection for the first time it was only for a moment!  And it wasn’t in a program or class, it was with a group of friends practicing what we learned from a program we all had attended.  Once you experience it, what then?  You want more, you need more, you want it to last longer, but how?  In my experience I have found that I feel one with the earth, myself, and connected to those around me when I am regularly working on skills and projects from the days of our ancestors. Whether it’s bow making, animal tracking, or studying wild plants, these skills form a direct connection to the earth, our ancestors, and our deeper selves. Another way to achieve this is by venturing out without time or a destination.These traditions are some of the keys that open the doorways to the past, present, future & inner peace! Take the journey, leave the watch and phone behind. Learn to travel without time or destination and most importantly enjoy yourself!

At Ancestral Knowledge we are dedicated to helping people find their passions!  If you would like to get started on the personal journey of a lifetime let me know how we can help you get started. 
Thanks for reading!

Future Primitives- Teen Skills and Leadership Training is under way!

We are so excited to have full enrollment in our Future Primitives program!  We are having a great time hanging out and working on our projects.  We have had three meetings and we have already accomplished so much!

So far everyone has made their own personal bow drill kits and we even had a PFF! (Personal First Fire)  Everyone has established a sit spot and began their nature journals, making entries about the weather and the animal activities they have experienced while visiting them.  We have erected a sundial to track the earths movements to increase our directional awareness.  We have lit several fires during our emergency fire drills, one participant came prepared with a steak to learn how to cook on an open fire.  let’s not forget about the GAMES!  You never grow to old to play games, but now they involve sticks and stones, bows and arrows, and the occasional blindfold!

 

Animal Tracking Workshop

bev1bev2On April 18th Ancestral Knowledge hosted its first animal tracking workshop. The workshops was taught along t the Paint Branch Creek in College Park MD. This area is rich with animal diversity and hosts one of the finest sand bars in the area. I spent over 16 hours a week for over 2 years tracking and observing animals and animal behavior in this location, in essence this is were I became a tracker. It was a beautiful day reaching 70 degrees with a light wind from the south. We spent 6 hours tracking 4 different animals. Finding each print and identifying its species. The first trail we followed was a treat, having only seen clear tracks of this animal on 2 occasions in 2 years and never having seen a full clear front track. Today we had the gift of seeing several trails and trail conditions. The first two pictures are of this animals trail and I will leave it to you to try and figure out who it was we were following. As the day progressed the tracking became more and more difficult. The suns angle was changing and they were put on more and more difficult trails to follow. The third trail was along a run where fox traveled back and forth frequently. The trackers had to figure out which trail was connected to the original track I set them on. Track aging was crucial but not impossible to determine which tracks were from the night before and the ones laid that morning. deer1The fox was doing its typical 2 x trot. After a short break to mend our tracker headaches we moved into the wooded area along the creek to look for some good deer tracks to follow. Tracking in leaf litter is a bit more challenging then on sand as you can imagine. After a short walk I found two great trails to follow. These trails taught the trackers a great deal about becoming the animal and seeing through their eyes. One trail was a meandering slow walk as it ate along the way. The other trail was of a cautious deer as it approached a bike path. The trackers quickly learned to expand their awareness to their surroundings to notice the different plants the deer nibbled on and the sight lines that the other deer paused for to check if anyone was coming along the bike trail before crossing. All in all it was a great day and I look forward to sharing the wonders of tracking in the future.
