Body temperature (sc) of NoStress and Stress rats in the cold. Rats were placed in a cold room 4 days after last stressor and sc body temperature was recorded. Data were analyzed at basal, 30 and 60 min time points in the cold room. A) Body temperature in the cold room. Body temperature of Stress rats at 60 min in the cold room was significantly lower than basal (*, p < 0.05) and NoStress rats at 60 min in the cold room (#, p < 0.05). The basal temperature between NoStress and Stress were significantly different (&, p < 0.001). NoStress group significantly elevated body temperature from basal in the cold room at 30 and 60 min ($, p < 0.001) B) Change in body temperature in the cold room compared to basal. Body temperature of Stress rats was significantly lower than NoStress rats at 30 and 60 min in the cold room (*, p < 0.001). NoStress rats significantly elevated body temperature at 30 and 60 min in the cold room (#, p < 0.01) (n = 23–24 per group).
