Feeling colder than usual

Coldness is a typical sign of iodine insufficiency. According to some research, over 80% of persons with low thyroid hormone levels may be more susceptible to cold temperatures than typical. Because iodine is required for the production of thyroid hormones, a lack of iodine might result in a drop in thyroid hormone levels.

Because thyroid hormones regulate the rate of your metabolism, low thyroid hormone levels can cause it to slow down. A slower metabolism produces less heat, making you feel cooler than normal. Thyroid hormones also assist to increase the activity of brown fat, a kind of fat that specializes in producing heat. This suggests that low thyroid hormone levels, which may be caused by iodine shortage, may inhibit brown fat from performing its function.
