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.
Too dry and your skin or nasal passages may feel dry; too moist and it may feel clammy indoors. Besides comfort levels, the humidity level is a concern because extremely damp conditions may cause mold or mildew, which can lead to or exacerbate health concerns.deal summer and winter indoor humidity vary; in the winter, ideal humidity is in the 25 to 40 percent range; in the summer, less than 60 percent humidity is ideal. In the winter, air in the home may feel dry, especially if the humidity outdoors is low.
