As the winter chill rolls in, many of us are reminded that cold and flu season is upon us and scientists may have discovered why colder temps can lead to a rise in illnesses. A new study discovered that immune responses within the nose become more dormant when cold weather takes over. Researchers found that when the temperature drops by even 9 degrees Fahrenheit, half of the virus and bacteria-killing cells that live inside our nostrils die. The science also found that the warmer we keep our noses, the more cells fighting off bacteria and viruses survive—so covering your nose with cozy scarves or masking up can protect you from getting a cold.
