RE: Low temp, high humidity?

Can someone please explain the correlation between low temperatures inside a residential home and high humidity. I was told to lower the temperature inside the higher humidity, Which seems to be true. But I don’t know how to explain that to homeowners. Example today tstat set for 64, temp inside 66 humidity inside 92%.

Relative humidity is relative to the amount of moisture the air can hold. When the temperature is lower the amount of moisture it can hold is lower. The actual grains of moisture didn’t change, the air is just closer to dewpoint (100% RH).
