It is common to experience cold and nasal blockage after exposure to air conditioning, which can dry your nasal passages and trigger mild allergic reactions.

🩺 What You Can Do Now

• Use a saline nasal spray or rinse to help clear nasal blockage and moisturize your nasal passages.
• Stay hydrated by drinking warm fluids like herbal teas or warm water with lemon and honey.
• Rest and avoid further exposure to cold, dry air.
• Over-the-counter antihistamines like cetirizine may help reduce nasal allergy symptoms, but only take them if advised by a doctor.

⚠️ When to See a Doctor

• If symptoms worsen or persist beyond 7–10 days.
• If you develop high fever, severe headache, or facial pain.
• If you experience difficulty breathing or swelling.
