Water is good for us. Our bodies are made up of mostly water. Pink bags of water if you watched Enterprise. 60% water -I believe!
I drink mostly water. I find it helps with many of my problems. It reduces fluid in my ears, it helps with inflammation and soothes my thirst.
When I took a boot camp exercise class, my body ached everywhere and I could barely walk, so I took a bath. Oh the relief I got from soaking in the tub was tremendous!
So now when I overdo, which is easy, because I am out of shape. Also, with the fibromyalgia and osteoarthritis I get sore easily... so baths help restore me.
The next time your muscles ache, instead of reaching for pain killers or a rub, try a bath, a pool, the ocean, a hot tub... It may help you. I know it helps me.
