>>19273260>it has an effect on the fat cells- it does its called Cold Thermogenesis and works this way; The cold immersion shock triggers release of epinephrine which acts as an alpha adrenergic receptor blocker antagonist which thus allows access to stored fatty acids in fat cells. The cold effect over time reducing core temp increases metabolic function in order to preserve normal body temp so you can use that now accessible stored fat as fuel to maintain body temp while you remain immersed as that is draining away your heat. works best in a larger body of water as in an ice bath the ice eventually melts and the water temp will fail to keep you in the higher metabolic state
I have been doing this by swimming in the Atlantic off New England for years and sleep naked with just a sheet often all year .
