Today I consulted on a 4 year old log home with very high humidity. Here is some background.

If the outside air temperature in winter is 0°F and the relative humidity is 75 percent, that same air inside your 70°F home will have a four percent relative humidity. That’s dry! The Sahara Desert has an average relative humidity of 25 percent.

Michael,
So the human body is comfortable with a humidly of between 20 & 60 percent,
The complaint is High Humidity in a tight Home (Logs read 13% doesn't sound like it's building up to cause any moisture damage.)
Solution to a home owner complaint is to ventilate the conditioned space.
