Cold Weather and The Common Cold -- Are They Connected?
December 16, 2015
By WeatherBug Senior Meteorologist, Julie Gaddy
Did you know there are many different types of viruses that cause the common cold? These viruses are present throughout the year, regardless of how cold it might be outside. Cold weather does not cause colds, however, there are a few weather-related variables that can lead to a higher number of colds occurring during the winter.
The cold virus spreads the same way any other virus does, usually requiring close contact with someone who is already infected with the virus. The cold virus can live for several hours on objects such as toys, doorknobs, telephones, and computer keyboards. The virus can also be transmitted through the air, particularly in crowded spaces with limited air flow such as airplanes or buses.
Dry nasal passages make them more prone to a virus. This can be due to allergies or low humidity. The winter season is usually the season with the driest air. Winter is also the time where people tend to spend more time indoors to avoid the cold, leading to more frequent close contact with others. Holiday travels can also increase a person’s exposure to airborne viruses.
Age is a factor that increases a person’s chance to contract the cold virus. Children typically have lower immunity than adults. This combined with being close to others while at school or day care creates a higher risk. Stress and fatigue can also lower a person’s immunity to the cold virus.
Moving to a warm weather location won’t eliminate your risk of getting a cold. Instead, employ basic preventive measures such as washing your hands frequently, cleaning your desk and countertops with antiseptic wipes, using a nasal spray to keep them moist, and staying out of close contact with those who are sick.
