What do I do with my daughter when.....?

What do I do with my 14-year old daughter when she constantly argues with me about wearing a hat outside in cold weather, going out the door with wet hair, not wearing a scarf, and taking vitamins or eating breakfast, THEN gets sick and wants to stay home from school? Is there any truth to keeping your head and neck covered when it's cold outside will prevent you from getting sick? I gave her the option....you can stay home if you stay in your bed all day (there's no tv or computer in her
