colder weather really is not the cause of colds. the cause is the transmission of human cold viruses (and there are about 200 different kinds) that you get from other people. during colder weather people have their windows closed and people tend to stay in more crowded conditions like work or classrooms where cold viruses easily spread via the air or by contaminated hands and surfaces. hygiene is your key. wash your hands often and keep your fingers away from the nose and eyes. the two most common portals of entry for cold viruses. if you stay away from people. the source of colds. that would be helpful by certainly not socially desirable. while a flu shot only protects against influenza not colds it will help improve your immune system and maybe. just maybe you will get less colds. the average adult gets 2-3 colds per year not matter what they do to try and prevent them.
