Nasal stuffiness is another common reason for mouth breathing, because we
tend to breathe with our mouths open to compensate for not being able to
breathe through our noses. It is essential that you find out what is causing the
nasal stuffiness and treat it. Using Rhynil, which is safe for
long-term use, can reduce nasal congestion and catarrh.
You may also like to try steam inhalation. This traditional remedy is very worthwhile. Alternatively, if your nasal stuffiness persists you may find antihistamines can be very useful. Ask your GP or pharmacist for advice.
