Its not uncommon to have above 90% relative humidity readings. I find it uncomfortable once the humidity is over 70%, but I'm really not a 'good' test subject as I have lived in Florida all my life and have gotten use to high humidities. I can tell you one thing with certainity, the insects love the high readings! 60% is a threshold in the summer.
âMany patients with COPD have a component of asthma and some of those patients prefer warm, dry climates while others prefer more humid environments,â he says.In general, minimal humidity levels are best for COPD patientsâabout 40 percent humidity is ideal.This is also true of indoor humidity levels, which can be difficult to maintain during the winter months, especially in colder climates where heating systems are running constantly.inally, if youâve been diagnosed with COPD and you live in a region of the country with high humidity levels, consider moving to a dryer environment. While doing so may not fully abate your COPD symptoms, it could help you avoid flare-ups.
