Feeling Cold
Many people with an iodine deficiency tend to be more sensitive to low temperatures than others. Given iodine is important for the production of thyroid hormones, the condition would decrease the levels of this substance. Since thyroid hormones are responsible for controlling the metabolic rate, low levels would slow it down. As a result, the body produces less heat, making you feel colder than normal. In addition, thyroid hormones are necessary for the activity of fat, which generates heat. That’s why less heat may be produced when an iodine deficiency occurs. [9]
