It is advised not to drink milk tea after catching a cold. Milk tea actually contains only a small amount of milk; it is mostly made up of various additives, colorants, and other concoctions. Consuming large amounts of these additives, colorants, and other chemical substances can be harmful to the human body. Especially during a cold, when gastrointestinal function is weak and the throat mucosa is congested, drinking milk tea can potentially worsen the swelling of the throat mucosa, causing more pronounced throat symptoms, leading to reduced gastrointestinal function and triggering acute gastric diseases. Therefore, it is recommended not to drink milk tea during a cold, and to generally reduce the intake of milk tea.
