Iron and cold sensitivity.

Iron and Cold Sensitivity

Women who often feel cold may be deficient in iron. Lack of sufficient iron, research has shown, blunts the body's response to cooling. Normally, when one is exposed to cold, the thyroid gland immediately starts to produce more than usual amounts of thyroid hormone, which performs as a stimulant and causes the tissues to produce more heat. Iron deficiency diminishes this thyroid response. However, this effect of iron deficiency upon the thyroid is correctable; the responsiveness of the gland and the body's response to cold return to normal just as soon as the deficiency has been corrected by giving some iron pills by mouth.

Since women lose iron with their monthly menstrual period, they tend more often than men to become iron deficient.

Furthermore, too many women consume less than the recommended daily allowance of iron (18 mg). Women who often feel chilly, therefore, might try taking some extra iron to see if it improves their intolerance of the cold. Before doing so, however, they should discuss this with their doctors.
