It seems pretty much normal that most women are colder than men, but this is just bad. I am constantly shivering in my own house, while my husband is sweating. I wear sweat shirts and pants ALL the time! My teeth chatter at work... and I wear a jacket in the office! I have been told I need more iron... how can I get more iron in my system? Is there just an iron pill I can take, or certain foods I need to eat?
