Why Does Red Wine Make My Sinuses Worse?
Red wine contains a high level of histamines, which are naturally occurring compounds in grapes. Histamines are responsible for triggering an inflammatory response in the body, which can cause the blood vessels to dilate and produce mucus. This is why some people experience sinus congestion or headaches after drinking red wine. Additionally, some people may also be sensitive to the sulfites, which are added to wine to preserve it, and can cause similar sinus symptoms.
