Present two possibilities for why a person might feel unusually cold indoors.
1. Anemia: One reason a person might feel unusually cold indoors could be anemia, a condition characterized by a decreased number of red blood cells or a lack of healthy ones. Insufficient blood flow could result in the body being unable to retain heat. 2. Hypothyroidism: Another possible reason is hypothyroidism, where the thyroid gland does not produce enough thyroid hormones to regulate the body's metabolism. A low metabolic rate could lead to reduced heat generation, causing the person to feel cold even in an indoor environment.
