Even after sinus surgery, I’ve always known that my sinus pressure and pain was partially due to in-home air quality. I’ve spent a lot of time researching air filters and cleaners, covers, animals, and plants. But I’ve never looked into the humidity levels. I only pay attention when winter comes and whatever I touch creates a loud and bright blue shock of static electricity. The dogs hate it when I try to pick them up. They make a run for it!
Looking at some of the research out there, it appears that having proper humidity levels inside the house not only helps relieve sinus pressure and headaches, but also helps prevent colds and influenza. Of course there are limits. Many sinus sufferers face problems with low humidity. That’s when influenza and colds begin proliferating inside. Having high humidity can breed mold and dust mites, which can aggravate and set off allergies.
Where I live, high humidity is never a problem. The problem is ever-changing levels outside during most of the year, and low humidity during the winter months at times.
Of course, it is an individual and family based decision, but most humidity levels should be set between 35-55%. I aim for 45% because of the severe allergies in my family (need to stay below 60%), and the sinus issues we all have (over 35%), as well as the fact that we have school-aged children.
75-80% humidity is the level in which dust mites thrive.
60% humidity is the level in which molds thrive.
Low humidity leads to an increase in the risk of influenza.
