Chronic psychosocial stress may cause asthma exacerbations

Stress activates the hypothalamic-pituitary-adrenal axis. Release of endogenous glucocorticoids may play a role in airway homeostasis.

Chronic psychosocial stress evokes asthma exacerbations.

Animal studies suggest that social stress induces corticosteroid insensitivity. Such mechanisms amplify airway inflammation in response to infections, allergen, or irritant exposure.
