Can I drink mineral water when I have a cold?
Generally speaking, people with a cold can drink mineral water, but it is important to choose processed mineral water. The specific explanation is as follows:

Mineral water typically refers to water that has undergone natural filtration and mineral enrichment. It contains abundant minerals and trace elements, and moderate consumption is beneficial to health. For individuals with a cold, if the symptoms are mild—such as slight nasal congestion and runny nose—it is acceptable to drink a moderate amount of room-temperature or slightly warm mineral water. This can help replenish fluids and minerals lost by the body, promote metabolism, and aid in recovery.
If the mineral water is not properly treated and contains bacteria, viruses, or other harmful substances, drinking it may have negative effects on the body and hinder recovery from illness.
During a cold, maintaining healthy eating habits and avoiding excessively greasy or spicy foods, such as fatty meat and chili peppers, can help speed up the recovery process. It is also recommended to rest adequately, maintain a regular routine, and ensure sufficient sleep.
