So Cold Weather Really Does Make You Sick

I guess mom was right. Bundle up and put on that scarf, Yale researchers announced this month results of a research study which showed that lowering the temperature of respiratory cells by as much as five degrees makes them dramatically more likely to be infected by Rhinovirus, the most common cause of the common cold. Apparently the innate defenses of the cells to infection with these types of virus is impaired by cooler temperature. It also explains why these viruses do not cause lower repiratory tract infections, as the lungs are within the chest cavity and at core body temperature and possibly why the body has developed fever as a response to these infections.
