Blocked nose in morning: what it may mean

Symptoms that ease after you leave the bedroom can point towards dust, dust mites, mould, bedding or another airborne trigger. Sneezing and an itchy nose favour allergic rhinitis. Facial pressure, reduced smell or thick discharge can occur with sinusitis. A blocked nose with sore throat, cough or fever may be part of a common cold.

Air the room, wash bedding regularly, reduce dust build-up and avoid smoke or strong fragrances. Saline nasal spray or a gentle saline rinse may loosen mucus; use safe water and clean equipment for rinsing. Drink fluids and consider whether a fan or air conditioner is drying the room. A pharmacist or clinician can advise whether allergy medication is suitable.

Arrange a medical review if blockage persists, repeatedly disturbs sleep, stays mainly on one side, or comes with recurrent nosebleeds, facial swelling, worsening pain, high fever or a reduced sense of smell. Seek urgent help for trouble breathing, swelling around an eye, confusion or severe headache.

Could bedroom allergens be contributing? Would an examination or allergy assessment help? Which spray is appropriate for my symptoms, and how should I use it safely?
