The dirt cure
What I have learned is that ultimately, it all begins with dirt. Dirt means exposure to microbes, eating fresh food from healthy soil, and spending time in nature…If you feel wonderful when you’re gardening or hiking, it may be in part because Mycobacterium vaccae, a soil microbe that enters your body through your nasal tract or small cuts in your skin, boosts serotonin to levels similar to those from antidepressant medications, such as Prozac.
