Yes/no: Simply sleeping in a cold room won't burn any more calories but shivering will. However, you probably won't be able to sleep if you're shivering all night and you could get sick. Muscle mass won't be affected by sleep alone.
Dr. Robert Fietsam
Thoracic Surgery 35 years experience
Not much.: Your body is constantly burning calories, that is the BMR, basal metabolic rate. Does the BMR increase in a cold room? If you are shivering, then certainly. There is a significant muscle building during sleep, not muscle loss.
Dr. Ann Agnew
Specializes in Internal Medicine
Calories burned: You burn small amount of calories when you sleep. Less than when you exert yourself or are awake. Unless you are actively shivering you won't likely burn more calories in a cold room than in a regular room. You generally burn more calories in a warm environment. If you don't actively use your muscles you will lose muscle mass. Best way to burn calories and maintain muscle mass is exercise

Peristomal wound: When i see a patient who has difficulties with peristomal wound or pain, i generally try to ascertain cause. Usually, if there is no underlying pathology, the skin is irritated by the adhesive. Using a hydrocolloid dressing beneath the adhesive may reduce the difficulties.
