Scientists have discovered that mycobacteria found in soil can improve brain functions while improving mood. Mycobacterium vaccea found in soil increases the serotonin produced in the brain (also known as the “happiness chemical”). Therefore, being able to get this natural serotonin from the soil will give you a sense of well-being and lift your spirits. These “friendly bugs” also improve the immune system, and many scientists believe that our modern society would benefit from working with the land, as this could prevent cases of asthma, allergies and other diseases.
Science has confirmed that even looking at flowers or other organic products or picking herbs stimulates the release of dopamine in the brain.
