How do saline nasal sprays assist with upper respiratory issues?

• A. They reduce swelling in the throat
• B. They moisturize nasal passages
• C. They numb the nasal membranes
• D. They increase mucus viscosity

Answer: (B)

Saline nasal sprays primarily hydrate the nasal passages, keeping the nasal lining moist and comfortable. When the mucosa is well-hydrated, the nasal cells’ cilia can move mucus and debris more effectively, aiding drainage and clearing irritants, allergens, and congestion. This moisturizing effect also helps relieve dryness and crusting that often accompany upper respiratory issues. They don’t numb tissues or target throat swelling, and they tend to thin mucus rather than make it thicker, which supports easier expectoration and airflow.
