Putting our hands in soil and touching grass, trees or moss provides a wide range of health benefits, for our skin and wider immune system.
I take a long walk in my nearest park every day, almost religiously. There are plenty of different tree species to look at, an everchanging cast of fragrant flowers in spring, and enthusiastic birdsong fills the air. But the sensory experience usually stops there. However mucky my shoes get, I usually come home with clean hands.
