Even a slight chill increases the speed at which rhinoviruses, which cause the common cold, multiply in lab mice, said the study published on Monday by Yale University scientists. Cold temperatures also trigger immune-system changes that let the viruses replicate virtually unchecked.
Scientists have suspected for more than half a century that rhinoviruses thrive in a slight chill. A 1960 study found that they multiply more quickly at 33 degrees Celsius (91.4 Fahrenheit) than at body temperature (37C, or 98.6F.). —> Read More Here
