I use ice boots after harder training sessions in the hot summers here in AZ. My horse is 100% sound and healthy, but I think it's important to cool the tendons and ligaments after hard exercise. In the winter, when it's mild here, I usually just cold hose, but in the hot summers I don't even feel like our hose water gets cold enough to cool my horse's legs after work!
If you're curious about info and not just sort of polling people (can't tell from your post), this page has a few good articles on cold and heat therapy, but not on magnetic therapy. cold and heat therapy
Thanks! The link is useful. I follow a routine similar to yours. I guess I'm confused about magnets. My understanding is that they increase bloodflow, yet i've been reading articles about people using them to decrease inflammation, which seems contradictory. Am i confused. If what I said is true, when would I want that as opposed to the benefits of cold therapy.
