Cold weather causes colds and flu.
Although colds and flu are more common in the winter months, this has less to do with the weather than with confinement indoors. Viruses spread much more quickly in dry, heated, indoor areas where air doesn't circulate well, and direct contact with germs is far more likely. Plus, central heating systems dry out mucus membranes, which are the body's natural defense against viruses. Kissing spreads colds and flu. According to Inlander, colds are much more likely to be spread by hand contact than by oral contact.
