The temperature has dropped and it’s been down there for a while, so the big question is, does temperature change cause you to catch a cold? Most likely your mother told you it can, but medical studies say there is no effect. Basically, colds are caused by viruses, and the spread of viruses, particularly, the rhino virus. There is one theory that cold weather can suppress your immune system and make you more susceptible to problems, but this is under heavy study. In cold months, when the air is very dry to start with, people turn on their heating systems. That dry air can cause allergic symptoms to be made worse.
