Talking in a nasal-like tone and feeling congested for weeks at time is no fun. Then again, neither is sneezing, coughing, or constantly burying your face in a tissue. The common cold is an inescapable part of being human, it seems, and while many advances have been made in modern medicine over the last two centuries, the elusive instant cure-all for it remains as mysterious as a supermassive black hole. While many remedies, exist, there is no one path to feeling better. However, a new study reveals an interesting fact about temperature and nose colds.
Cold Temps Can Influence... the Nose Cold?
One of the most common forms of the cold—the rhinovirus—has been the subject of previous studies conducted in various temperatures. However, earlier research only focused on how the virus reacted to colder body temperatures. This new study headed by author and Yale professor of immunobiology, Akiko Iwasaki, sought to further investigate the relationship between higher temperatures and the immune-response rate.
To investigate this relationship, Iwasaki extracted cells from subjects' airways. She then compared the immune-response of the cells exposed to the rhinovirus when the cells were incubated at 37oC (98.6oF) or the body's normal temperature. The same comparison was made with a lower body temperature of 33oC (91.4oF). Findings suggested that the innate immune-response to the rhinovirus was impaired at the lower body temperature when compared to the normal body temperature.
"In general, the lower the temperature, it seems the lower the innate immune response to viruses," noted Iwasaki. This gives weight to remedies like hot drinks and hot soup when you have a cold. Keeping your body temp warm is actually scientifically helpful to your immune system when fighting off a cold.
The Importance of the Immune Response
While you may not be able to avoid the common cold and other mildly annoying illnesses, you can do your part to strengthen your body's immune response. Raising your body temperature by staying warm, as shown in the study above, and even covering your extremities (especially the nose) can help your body respond better in fighting off the cold as explained by the body temperature studies above. Supplementing with certain vitamins and minerals like zinc, vitamin C, and Echinacea can also support the body's immune system. While everyone will experience the common cold at some point, it doesn't need to be a losing battle.
