Can enhancing immunity prevent coughing caused by eating spicy food?
Enhancing immunity can help prevent coughing caused by eating spicy food to some extent, but it cannot provide complete prevention.

Boosting immunity means the body is better able to resist external pathogens and adverse stimuli, including irritants present in food. Eating more fresh fruits, vegetables, and high-protein foods—rich in vitamins, minerals, and antioxidants—can help strengthen immunity. Regular physical exercise, such as jogging, swimming, or hiking, can enhance bodily functions and improve immunity. Sufficient sleep also aids in body recovery and boosts immune function.
For individuals with specific health conditions such as asthma or gastroesophageal reflux disease (GERD), eating spicy foods may trigger coughing even if the immune system is functioning normally. This is because compounds in chili peppers can irritate the throat and airways, causing an inflammatory response, independent of immune system strength. Excessive consumption of spicy foods can directly irritate the throat and respiratory tract physically, leading to coughing; therefore, moderate consumption is recommended.
While enhancing immunity, it is also important to maintain good lifestyle and dietary habits, avoiding excessive fatigue and harmful irritants.
