Gardeners have long known that a few hours spent digging in the dirt can improve their moods. The sun, the focus on natural life, productive work; all of these things make us feel better about ourselves.
But a recent study shows that microorganisms in the soil have the ability to improve our brain chemistry, acting as an antidepressant. One more reason we should let our kids and ourselves play in the dirt. Perhaps our super sanitary way of living is harming our mental health.
So, get out the seed catalogs and start planning the garden. A little dirt therapy is in order this Spring.
