Impact
When nasal tissue swells during a cold (or allergic reaction), the airflow through the nose becomes restricted. This congestion narrows your airway, forcing the air you breathe to travel faster and further dehydrate the tissue. This may force you to breathe through your mouth – and this can lead to snoring.
Reducing your risk of allergies is a simple way to help prevent the obstruction of nasal passages. Try to control dust and bed mites by using an anti-allergen bedsheet and improving your bedroom cleaning regime.
Encourage your pets to stay off living room furniture and beds as this can aggravate pet allergies. If you suffer from hayfever, try to wash your clothes regularly and keep your windows closed to reduce the possibility of bringing allergens into the home.
If you frequently suffer from nasal congestion because of a cold or flu, try to eat a healthy, balanced diet and drink plenty of fluids to boost your immune system.
