You're right, big chested ladies!  You being under the weather longer than your smaller chested counter parts is not your imagination, is lasting longer than every body else.

Research is showing that women with larger breasts suffer much more with the common cold than others.  In fact, respiratory infections can last twice as long as those with smaller chests.

Here's what we know. According Unilad, who shared research published in the journal Archives of Sexual Behavior, women with F cups had colds, coughs and flus that lasted an average of 8.3 days compared to 3.8 days for women with AA cups.  Women with bigger chests had illnesses that lasted twice as long then women with smaller chests.

One theory as to why this is revolves around a hormone that is produced in fatty tissue, such as that in bigger breasts, that weakens the immune system making it harder for the body to recover from infections.

This could be another reason to stick to that New Years resolution to lose a little weight this year.  Maybe, that could help you not be 'down with the sickness' for so long in the future.
