Allergies & Rhinitis

Allergic rhinitis (from dust mites, pollen, mould, pet dander, cockroach droppings) is the most common cause. Non-allergic rhinitis from irritants, weather changes, or hormones is also common. Rarer: nasal polyps, deviated septum, chronic sinusitis. If symptoms persist most days for weeks, an ENT specialist or allergist can distinguish and guide treatment beyond over-the-counter antihistamines.

If symptoms are frequent, affecting sleep or quality of life, and unclear triggers — yes. Skin prick tests or specific IgE blood tests identify actual triggers. Random 'panel' tests without symptom correlation are often not useful. Testing is most helpful when it changes what you do (allergen avoidance strategy, targeted treatment, or immunotherapy consideration).

First line: nasal steroid sprays (fluticasone, budesonide) daily — often more effective than tablets. Add oral antihistamines for breakthrough symptoms. Avoiding triggers where possible (dust-proof pillow covers, keeping pets out of bedrooms, high-efficiency air purifier, wearing a mask outdoors during pollen season). For persistent severe symptoms, immunotherapy (allergy shots or drops) can gradually reduce sensitivity.

Cold: sudden onset with fever possible, thick coloured nasal discharge later, sore throat, resolves in 7-10 days. Allergic rhinitis: gradual, no fever, clear watery nasal discharge, itchy eyes/nose/throat, sneezing spells, can last weeks or seasons, often recurrent. Allergies are also often triggered by specific exposures (going outside, dust in the house, pet contact).

For dust mite, mould, pet dander, and outdoor pollution particles entering indoors: yes, HEPA-filter purifiers help — measurably so for larger units suited to room size. Not a substitute for allergen avoidance (dust-proof bedding, regular cleaning). Runs continuously in the room where you sleep for meaningful benefit. Cheap small units in large rooms don't do much.
