A method of maintaining advantageously stabilized homeostatic parameters through normothermic maintenance in particular in the peri-surgical environment is described. In particular, the method of advantageously applying insulative garments over a small but disproportionately effective percentage of the BSA in order to counter environmentally and surgically induced hypothermia. Further described is a method of maintaining normothermia using a disposable or re-usable, un-tethered, anatomically formed or substantially tube formed garment or plurality of garments preferentially configured to enclose the extremities and in particular the areas of the mammalian body which are the most effective loci of heat transfer. The method, whereby the positive heating attributes of the system may be augmented through the use of additional insulative garments, which garments may be disposed about the patients body to achieve greatest benefit to both patient and surgical field.
