What about the dangers of alcohol, which are also hard to foresee?
Asthma exacerbations may arise as a result from drinking alcohol. Among alcoholic beverages, wine is found to be the most common culprit in triggering asthma. Sulphur dioxide or sulphites is the main preservative in red and white wine. They work by inhibiting the growth of yeast that causes spoilage. However, a number of asthma sufferers reported wheezing and asthma exacerbations after or while drinking wine. This is mainly due to the presence of sulphites and not the alcohol itself. If left untreated, the allergy could lead to anaphylaxis (Anaphylaxis is a life-threatening type of allergic reaction).
