The processes

1.Drink water first thing when you wake up from sleep in the morning time

Reason why you should drink water,it help flush down dust ,small particles,and chemicals in the stomach to the urinary bladder

2.Get a mentholated Rub 

Do this after taking bath, Apply alot of mentholated Rub on your head, little in your nose holes, and also apply on your chest, 

Reason it will make you sweat out all the water in your body

With all of this I believe you will never have cough or catarrh through out the cold season.
