I've read that athletes and MMA fighters use Epsom Salt baths w/ Wintergreen alcohol to drop water weight and soothe sore muscles/joints.. They claim its supposed to remove extra-cellular water and spare the important intra-cellular water..I'm curious if this is actually accurate.. IMO the body would sense the lack of ECF and therefore release Intra-muscular fluid to maintain homeostasis/balance between the cell membrane. On the other hand, it's possible that if one sufficiently hydrates in enough time, that it would negate this from happening.. I know these baths have their muscle relaxing effects, but I think it would be canceled out by intramuscular dehydration if indeed that's what happens...
