Hidden Environmental Triggers of Cough in Your Surroundings
Environmental · Cough Triggers
From a protective cough to an unexplained problem
Cough is a protective reaction (reflex) of the airways but can become a disease when this reflex is dysregulated. At times when the known causes of cough have been excluded, a group of patients with unexplained cough remains.
What could be the reason for this?
Do you know what triggers dry cough?
A distinct form of chronic cough has been identified in some people, where the cough reflex (reaction) becomes unusually sensitive. Cough is often triggered by everyday environmental allergens such as strong smells, cold air, smoke, chemicals, and scents in these patients.
More than 60% of patients with chronic cough report that coughing could be induced by environmental allergens.
Chemical sensitivity cough shows symptoms from the eyes, nose, and lungs, as well as headaches and fatigue.
Given below are the factors that can be the possible causes of cough and how it presents.
- The type of trigger
- How strong it is
- How long you are exposed to it
- Your individual health (age and existing medical conditions)
