Hi CarolineR. Coughing for me, being a COPD sufferer, means expelling mucus from my lungs and respiratory system. What works for me is using pursed lip breathing to calm myself down and gain control of the cough. Then I use the huff coughing technique to expel the mucus. It works every time. I also use my Acapella device to help loosen the mucus in my lungs. Staying hydrated also helps a great deal. If you are not familiar with the breathing techniques, look them up on YouTube and you will see demonstrations of the techniques. I also take Mucinex daily to help keep the mucus moving out of my respiratory system. If your cough is non-productive and is more of a dry cough, then maybe contact your medical team for help. Hope this helped. Take care and God Bless!
