You should not drink honey water when you have a cough, because coughing is an upward movement of the lung gas. There are many causes of coughing, such as respiratory tract infections, acute tonsillitis, acute bronchitis, acute pneumonia, or allergic coughs that do not heal for a long time. The inflammation of the respiratory tract has a lot to do with the diet, especially eating sweet, high-calorie, high-protein foods, which can cause the lungs to produce phlegm and produce a cough. If you drink honey water during a cough, it can aggravate the cough and inflammation. Because honey water has a high sugar content, it is not good for coughing. In the case of children, it can also lead to impaired spleen and stomach function in children, causing indigestion and diarrhea. For people with a history of coughing, honey can be consumed during normal times, but it is best not to drink it during coughing.
