Cold and damp is bad, no matter what you may have heard recently about it making no difference. The common cold virus reproduces itself more efficiently in the cooler temperatures found inside the nose than at core body temperature, confirming the popular-yet-recently-contested notion that people are more likely to catch a cold in cool, damp conditions. Scientifically it is known that the rhinovirus, the most frequent cause of the common cold, replicates more readily in the slightly cooler environment of the nasal cavity than in the warmer lungs but, the focus of prior studies has been on how body temperature influenced the virus as opposed to the immune system, said study senior author and Yale professor of immunobiology Akiko Iwasaki. read more
