Do you believe that swimming in the rain can lead you to catch a cold? If your answer is no, you are correct!
You will have higher chance catching a cold if you stand in the rain for a sufficient amount of time because your body temperature will be lowered below normal. And, when your temperature drops below normal, it becomes easier for viruses and bacteria to attack. Since you go swimming when you are hot, your body temperature is not as likely to drop below normal, so you are less likely to become ill.
