Blocked nose in summer: possible triggers and relief

Sneezing, an itchy nose and watery eyes fit allergic rhinitis; symptoms after cleaning or in dusty rooms may involve house dust mite allergy. Air conditioning can dry the nasal lining, while sudden heat or strong smells may cause non-allergic swelling. Fever, cough or sore throat can accompany a common cold. Facial pressure or reduced smell deserves attention because sinusitis can also occur in warm weather.

Keep indoor air comfortable rather than very cold, clean filters as recommended and avoid directing a fan at your face. Limit smoke and strong scents, rinse after outdoor exposure if pollen is a trigger, and use saline spray for dryness or mucus. A pharmacist can explain whether allergy medication fits your symptoms and other medicines.

Book a review when blockage lasts, returns each summer, affects sleep, or is mainly on one side. Prompt assessment is sensible for fever with worsening pain, facial swelling, repeated nosebleeds or a reduced sense of smell. Get urgent help for difficult breathing, eye swelling, confusion or a severe headache.

Does the timing suggest an allergy or an irritant? Should I change my indoor-air routine? Which treatment is suitable if symptoms return each summer?
