Well where you live matters as to you may be in location (like me) that has very high humidity with hot temps, allergens (trees, flowers, pollen, smoke, pollution).
I live in eastern North Carolina and the humidity and high temps have already limited me. I also have COPD emphysema and Asthma...I call it the Double Whammy !
Living with both COPD and asthma together is known as asthma-COPD overlap syndrome, and it can lead to more severe and complicated symptoms than either condition alone — including worsening breathlessness. So what you're experiencing isn't unusual, but it absolutely deserves attention.
Worsening breathing over time can be Show Full Answer
From what I understand, COPD is worsened by lung infections. I suppose that air complications such as smoke and humidity may make breathing more difficult but it shouldn’t affect the progress of the disease.
I’m open to correction if I’m wrong.
My breathing issue changes throughout the day that medication makes a huge difference. When I see a gradual change in my ability to breathe it is usually because I have not kept my body hydrated which causes thick mucus in my lungs that is hard to cough up. I bought unflavored electrolyte powder from Amazon that i use to help with hydration (talk to your doctor). I try to have coughing session two times a day to help clear my lungs.
Environmental issues like season changes usually keep me indoors.
If my breathing gets too labored the anxiety kicks in adding another level to the game. Not fun at all!!
