Cold Weather Will Not Give You A Cold.  You've been out and got caught in the rain. Shivering and soaked, you feel cold right down to your bones. You've plunged into a hot bath as soon as you got home and didn't feel warm till the next day. Somehow you just feel like you're actually getting ill while it's happening -- but you are wrong.
Both cold and flu are caused by infections, usually by people sneezing or touching their nose with their hands and transferring germs to an object that you then touch (a door handle, for example, or a newspaper). The most common way a cold is transferred is by a handshake. People would argue that when you're cold, your immune system is less effective at fighting these germs and, thus, you are more likely to catch a cold. But again, this is false. Tests have shown that you are just as likely to pick up a cold in the balmy heat of the tropics as you are in Alaska.
