Chronic intermittent exposure to cold (+4°C, 8 hours/day, 4 weeks) promoted an increase in the weight of brown fat, spleen, kidneys and heart, stomach ulcers and an alteration of cortisol and corticosterone levels were did observed. Short-term intermittent exposure to cold (+4°C, 1.5 hours/day, 4 weeks) did not affect the weight of brown fat, but promoted an increases in the weight of body, spleen, kidneys and heart, stomach ulcers were not found, cortisol and corticosterone levels was not changed.
