Condition
Hyperpnoea-Induced Bronchoconstriction (HIB)
Hyperpnoea-induced bronchoconstriction, also called exercise-induced bronchoconstriction, is a temporary narrowing of the airways during or after hard exercise, when fast, heavy breathing dries and cools the airway lining. People often look at vitamin C, omega-3 fats and caffeine for it, but little research on them has been reviewed here so far. Ideas about how they might help, such as calming airway inflammation, remain largely theoretical for now.
