Effects of Winter’s Chill
Dr. Bruno’s Original Post: WINTER'S HERE! WELCOME POLIO FEET?
Polio survivors have blood flow to the skin of the legs and feet that's too good, causing hot body-core blood to dump its heat, makes leg blood vessels contract and legs and feet get cold and purple. Polio survivors' skin temperature is 20° LOWER than the outside temperature, so 65° acts like 45° at the surface of polio survivors' skin.
There are several articles on polio feet and keeping legs warm in the Encyclopedia of Polio and PPS. Look in the Index under the topic “Temperature”.
