The absolute quantity of moisture will tell us the real absolute quantity of moisture into the air, that is Dew Point an not RH. It means that the air is saturated and we will see dew on the grass. At DP of 21C the air is very humid. The comfortable limits is between C DP. Am I right? In this case presented we have to humidify, ventilate etc our house according to DP and not RH. Pohl, the body responds to Pohl, the body responds to relative humidity, not so much to absolute humidity.

But keeping these levels throughout the season requires a bit of juggling. The outside air naturally affects the humidity in your home whenever doors or windows are opened. A typical forced-air heating system will also contribute to the low humidity by replacing the interior air with drier outdoor air.
But humidity in the home when the outdoor temperature is freezing or below can lead to water and ice buildup on windows and, even worse, mold along the walls. A good rule to follow is that the lower the outside temperature, the lower your humidity should be. Most modern HVAC thermostats allow you to set the humidity level in your home, but a hygrometer which can be found at any home improvement store will also give an accurate measurement.
In order to get the best all-around results, indoor humidity levels should be adjusted according to the outside temperature. Here is a short tip-sheet for a home set at a comfortable 70 degrees:.

Boil water and cook using the stovetop. Leave lids off of pots and pans to release even more moisture. Set out a pan or vase of water. Leave open containers of water on top of radiators or near heating vents, and the water will slowly evaporate into the air. The warmth from your heating system will help speed this process along.
You can use decorative vases or vessels that add to the decor of the room, and even include citrus peels, vanilla or essential oils to provide a pleasant scent while you humidify the room.
