Milk can make you feel uncomfortable but it’s not causing your body produce more phlegm, which is the thick viscous substance secreted by the mucous when someone is suffering from a cold. Drinking milk, however, can make it a bit thicker and as a result can be irritating. Some doctors actually recommend eating dairy products, including ice cream, because they are comforting on sore throats.
