Cough

Definition

A cough is a sudden, forceful expulsion of air from the lungs as a reflex action to clear the airway. It can be triggered by irritants, infections, or chronic pulmonary conditions.

5 Must Know Facts For Your Next Test

1. Chronic coughs can result from respiratory illnesses like COPD and asthma, which are significantly impacted by nutritional status.
2. Malnutrition can weaken the immune system, making it harder for the body to fight off infections that cause coughing.
3. Certain nutrients such as vitamin C and zinc play crucial roles in maintaining respiratory health and reducing the frequency of coughs.
4. Dehydration can thicken mucus, making coughs less productive and more uncomfortable.
5. High-fat and high-sugar diets may exacerbate inflammation in the airways, potentially leading to more frequent coughing episodes.
