To help shift the mucus, drink plenty of warm drinks avoiding milk products because this encourages the formation of mucus.
Also do steam inhalations. Take care not to get scalded. Get a bowl and pour in boiling water from the kettle, add a little bit of Vick or olbas oil. Bend your head over the bowl and cover your had and bowl with a towel.
Breathe in through your nose and exhale through the mouth.
Do this for 10 minutes.
If you can, do this 4 times a day with a duration of 10 minutes each time.
You can buy tablets that will dry up the mucus, but these are not suitable for people who suffer from high blood pressure.
A nasal spray can also be used short term to unblock the passages.
