Air pollution, specifically particulate matter (PM), exacerbates rhinitis. Nutritional supplements show potential for prevention and management, though more research is needed to confirm their efficacy in reducing inflammation.
Area of Science:
- Environmental Health
- Immunology
- Nutrition Science
Background:
- Air pollution, especially particulate matter (PM), is a global health concern linked to respiratory issues.
- Rhinitis is a common condition exacerbated by environmental factors like air pollution.
Purpose of the Study:
- To review the association between air pollution and rhinitis.
- To explore the role of nutritional supplements in mitigating PM-induced inflammation and rhinitis.
Main Methods:
- Comprehensive literature search of PubMed and Scopus databases.
- Inclusion of studies investigating air pollution, rhinitis, and nutritional interventions up to 2024.
Main Results:
- PM exposure is linked to increased rhinitis prevalence and severity via inflammatory pathways.
- Limited evidence currently supports specific supplements (kefir peptides, lactoferrin, vitamin D, PUFAs, probiotics) in managing PM-induced rhinitis.
Conclusions:
- Nutritional interventions may offer a complementary strategy for preventing and managing air pollution-associated rhinitis.
- Further research is required to validate the efficacy of nutritional supplements in modulating immune responses against PM-induced inflammation.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
