An ounce of ground (that is bare feet on the ground) is worth a pound of Ibuprofen. As you can see it was a foggy day, and cold.
But because I know that having my bare feet on the earth is remarkably good for reducing inflammation in the body, this is what I did.
Yes, my feet got cold. But wet sand, especially wet with salt water puts me in direct contact with the earth and that means negative ions. Negative in this case is a good thing. Negative ions are beneficial to the body. Even 20 minutes, even on a cold day is far more effective than taking pills. I feel better, my immune system is boosted, my joints are much less creaky. Try it and see.
