Cold water therapy has shown to reduce inflammation in the body. There has been studies if it will help slow progression in ALS. Nothing official but I've seen people with ALS try it and if you can tolerate the ice cold water it has helped with slowing there progression. It doesn't apply to everyone but worth trying in early stages.
My wife Jennifer and a group of women do cold water therapy everyday up in northern Wisconsin. Bur!
