Anything containing ephedra is a bad idea while on stand , you' ll have to get rid of all the urine produced in your efforts to stay hydrated . This translates to lots more odor that will alert the deer . Carb loading , along with layered clothing and insulated boots , is still the best remedy for cold days in the woods . Protecting yourself from the cooling effect of the wind will also go a long way toward improving your comfort level . Protect your feet and head from losing heat at all times , you lose most of your body heat from these parts . A brisk 20 minute bout of circuit training before you prepare for the hunt , combined with carb loading , will not only raise your metabolic rate but help you lose weight as well . Don' t forget to descent yourself before starting out to your stand . Remember , there is no chemical substitute for common sense measures . A fit hunter is a better hunter , and a warmer one .
