Research indicates that although cold weather doesn’t cause colds, it facilitates the spread of respiratory viruses like influenza and COVID-19, increasing infection rates.
Many viruses remain infectious longer in cold temperatures, and with people spending more indoor time, germs spread more easily during winter months.
Cold weather affects the influenza virus’s outer membrane, making it more solid and rubbery, which enhances its transmission from one person to another.
COVID-19 does not follow the typical seasonal pattern of cold-weather respiratory viruses, as infection rates have risen even during summer months.
