From:  Targeting redox imbalance in pediatric asthma: environmental control, antioxidant strategies, and nutraceutical interventions

 Environmental control strategies aimed at reducing oxidative stress in asthma.

StrategyMain actionsRationale/Expected benefit
Reduction of air pollutant exposureMonitor daily air quality indices; limit outdoor activity on high-pollution days; use indoor HEPA filtration.Decreases inhaled particulate and gaseous oxidants that trigger airway inflammation and oxidative stress.
Elimination
of tobacco smoke
Maintain smoke-free homes, cars, and childcare environments.Removes a potent source of oxidative and inflammatory airway injury; improves overall lung function.
Indoor allergen controlControl humidity < 50%; use mite-proof encasings; remove mold and pet dander; avoid high-VOC cleaners.Reduces allergen-driven inflammation and secondary ROS production.
Ventilation and indoor air quality optimizationEnsure adequate ventilation; avoid biomass fuels, incense, and scented products.Prevents accumulation of indoor oxidants and volatile compounds.
Dietary
and lifestyle support
Promote antioxidant-rich diets (fruits, vegetables, nuts, olive oil) and regular physical activity.Enhances endogenous antioxidant defenses and reduces systemic oxidative stress.
Public health and urban interventionsSupport policies for cleaner transport, reduced industrial emissions, and green spaces around schools.Lowers long-term population exposure to environmental oxidants and benefits community respiratory health.

ROS: reactive oxygen species; VOC: volatile organic compounds.
