Is there such a thing as a man cold?
In the medical literature I dug up this article, published in 2007, that explores gender differences in the incidence of respiratory tract infections. Data were extracted from 84 relevant studies.
Men seem to develop more respiratory tract infections than females, except sinusitis, ear infections and possibly tonsillitis. The course of these infections may be more severe in men than women.
Why? Not sure, but it may have to do with anatomic differences, the impact of sex hormones on regulation of the immune system, lifestyle and behavioral issues.
Regardless, there is no need for us to overreact (as some are prone to do). A cold is generally still a cold.
