Drinking milk during a cough and cold is generally safe and does not increase mucus production or worsen symptoms. Scientific studies show that milk does not cause the body to produce more phlegm or mucus, although some people may feel that milk makes the mucus thicker and more noticeable, which can create a sensation of increased phlegm. Warm milk in small amounts may even soothe the throat. However, some factors to consider include avoiding flavored sweeteners or additives in milk, not drinking very cold milk straight from the fridge, and not drinking milk while lying down, as these might worsen symptoms. People with a cow's milk allergy or specific respiratory conditions should follow their healthcare provider's advice. In summary, milk itself is not harmful during a cough or cold and can be a good source of nutrients, but the way it is consumed can affect comfort during illness.
