Can colds result from low temperatures or being outside in the rain?

Getting a cold: "colds" are usually caused by viruses, typically spread by inhaling droplets when someone coughs or sneezes, or by touching contaminated surfaces. While you cannot get a cold only by being out in cold or rainy weather, if someone develops hypothermia due to excessive cold exposure with lowering of core temperature, it might affect their immune system making them more susceptible to infections.
