Can the Rain Make You Sick?

While being caught out in the rain may not directly make someone sick, it can increase the risk of being exposed to an illness. Cold, rainy conditions can cause body temperatures to drop, potentially low enough for hypothermia to set in. Hypothermia can weaken the body and strain the immune system. When it rains, it can elevate bacteria and viruses from the ground and into the air making easier to affect an individual.
