Respiratory allergies, including allergic rhinitis and allergic asthma, occur when the immune system reacts to allergens in the air. Although the symptoms of respiratory allergies can vary from mild to severe but may worsen depending on the level of allergen exposure. The common triggers include pollen, dust mites, pet dander, and cockroach droppings. 

When exposed to these allergens, our immune system releases chemicals that cause symptoms such as sneezing, nasal congestion, coughing, wheezing, and shortness of breath. Which significantly impacts the quality of life and may lead to further complications if left unattended.
