Dirt is mainly good for you – especially for children

January 21, 2012 Gut Flora/Bacteria, Resources 1 Comment

Dirt is mainly good for us. Here is a helpful post that explains this. First a Snip:

Bacteria has a bad reputation, as though any and all of it will hurt you. Parents keep immaculate houses in attempt to eliminate the “threat” of bacteria, removing shoes indoors, washing hands with anti-bacterial soap, moping with disinfectants, cleaning the counters with bleach. All of this is not only unnecessary for health but harmful to the immune system. It’s surprising just how many benefits there are to getting (and staying) dirty.

1. Mycobacterium vaccae improves mood
There are all sorts of beneficial bacteria living in the dirt but one that has been well researched is called Mycobacterium vaccae (M. vaccae). This bacteria has been shown toallay depression.

It is not entirely clear why but researchers have found that contact with the bacteria releases cytokines which activate the nerves in our bodies to relay signals to the brain and release serotonin into the prefontal cortex – the part of the brain involved in mood regulation (exercise has been shown to have similar effects).

2. Mycobacterium vaccae is linked to higher IQ
This same release of serotonin that occurs when playing in M. vaccae laced dirt, has also been shown to improve cognitive function. The serotonin that is released whilst playing in the dirt temporarily boosts the IQ so that learning is facilitated.

3. Staphylococci heals wounds
Staphylococci often gets a bad rap but it has it’s benefits as well. Staphylococci can prevent inflammation. After an injury if staphylococci is present on the skin, the redness and swelling which often accompanies cuts and scrapes can be prevented. Forget the ointment, just use a good smearing of dirt before you bandage up!

4. Soil microbes boost the immune system
Playing in the dirt introduces the immune system to bacteria which it can then store in memory. The memory of the immune system is profound and protects a growing body from getting sick later in life. A strong immune system also provides resistance to allergies.

5. Clay improves digestion
Dr. Weston A. Price noted in his book Nutrition and Physical Degeneration (one of my favorite books on earth by the way) that clay was “the treatment used by several primitive races forpreventing and correcting serious disturbances in the digestive tract. This consisted in the use of clay or aluminum silicate which modern science has learned has the important quality of being able to adsorb and thus collect toxic substance and other products…” He also noted a common thread running through all of the primitive cultures he studied was that they carried clay in their backpacks. 

Clay isn’t found in every dirt mound but it always seems that kids are magnets to it. It lays deeper in the soil and is fun to play with.

What is the Missing Human Manual All About?

Do you want to age well? Most of us do. If you are my age, 60, this is more important a question that if you are 30. But most of us would not wish to have heart disease, cancer, dementia when we get old.

Most of us think it is normal that we will get ill like this.

But science today tells us that this is not "Normal". Our evolutionary past designed us to be active and fit until we drop dead. Why? Because raising human children takes so long. Mature adults had to do most of the hard work enable us to invest up to 25 years in our kids.

We are designed by our evolution to reach a plateau of fitness in mid life. So why do most of us not live like this?

We don't because, we have strayed away from the best way of living that fits our evolution best. Our culture has got too far ahead of our biology. We eat foods that make us ill. We have lost our social identity and power and that makes us ill. And we have lost touch with the circadian rhythms of the Natural World, and that has made us ill too.

We have lost our fit with our true nature.

This site will be a Manual. It will show you what the best fit is. It will show you the science behind this. It will share with you some methods for getting your fit back with your true human nature.

So welcome to the "Missing Human Manual" . I hope that we can help you and I hope that you can help others as a result.
