Hello John! Thank you for using feature #AskSudrex. If you ever get wet in the rain; change your clothes as soon as you reach home. By doing this, the body temperature will return to normal. Wipe your head with a towel. If your head is wet for a long time, you may catch a cold or cough. Have a cup of hot tea; it will help your body regulate the temperature. You can treat your symptoms with Sudrex Cold & Cough.
