The new study, from Yale University and published in the Proceedings of the National Academy of Sciences, has revealed the importance of keeping your nose warm to keep yourself healthy. That’s right, just as it’s important to wear a warm coat to protect your body, a hat for your head, and gloves to protect your hands, you may want to start keeping your nose warm under a scarf.
By examining the immune response in different temperatures, the researchers were able to discover that a colder nose increases the likelihood of developing a cold. Their findings were based on the activity of airway cells within mice. The rhinovirus – the cold virus – was examined in noses of mice at both body temperature of 37 degrees Celsius and again at a cooler temperature of 33 degrees Celsius.
