How To Get Rid Of Covid Cough

Clearing your lungs after COVID-19

When you are discharged from hospital you may find that you are still coughing up phlegm or mucus. This is normal after a respiratory infection like COVID-19 (coronavirus). Do some exercises to clear the phlegm from your lungs. This will improve your lung condition.

Doing some exercises to expand your lungs will help your recovery by:

increasing the amount of air inside your lungs
improving the strength of your muscles that you use to breathe
helping to clear phlegm and mucus from your lungs
preventing collapse at the base of your lungs

Deep breathing technique

Deep breathing is a simple technique to expand your lungs and help clear your phlegm. You can do this many times during the day in any place or position. Make sure you are comfortable and your chest and shoulders are relaxed.

Sit or lie in a comfortable position.
Put one hand on your tummy just below your ribs and the other hand on your chest.
Take a deep breath through your nose, and let your tummy push your hand out. The hand on your tummy should move more than the hand on your chest.
Breathe out through pursed lips as if you were whistling. Feel the hand on your belly go in, and use it to push all the air out.
Do this breathing 3 to 5 times. Take your time with each breath.

help expand your lungs

help you have a stronger cough to clear your secretions

Wait for an hour after having food or drink before you perform these exercises. If you have any chest pain during the exercise, stop the exercise.

Breathe out fully.
Take a small breath in through your mouth, nose or both and hold.
On top of the air already in your lungs, take another small breath.
Repeat until you feel you cannot take in any more air and hold for 2 to 5 seconds.
Exhale the air out of your mouth. This will feel like a large breath out with a greater force.

Clearing phlegm from your lungs (postural drainage)

Your lungs have 5 lobes and phlegm can be in any of these.

Positioning exercises using gravity to help clear phlegm that has built up in your lobes.

How effective they are will depend on the thickness or stickiness of your phlegm. It may be harder to clear thick phlegm. These exercises may not work if your phlegm is very thick and sticky.

Wait for at least 1 hour after a large meal before starting these exercises. Stop this exercise if you have heartburn or feel sick during it.

Lie on your back with your head flat and your knees bent.
Place pillows under your hips and knees so that your hips are higher than the level of your chest.
