The only way to really know if cold immersion works for you is to get a tub, fill it with ice, or invest in a dedicated setup like the insulated tubs with chillers from our friends at Ice Barrel. Personally, I use the Ice Barrel 500 with a chiller every day, it makes spending 4-5 minutes in 43-degree water much more manageable. That said, as a former NFL player who used to play in Green Bay, WI, in short sleeves during January games in sleet and snow, my tolerance for cold might be a little different.
