Our bodies (the upper airway) normally warm and humidifies the air we breath in to 100% relative humidity at 98.6f.
The air movement of CPAP has a cooling effect which wreaks havoc with this conditioning system. This interferes with the defense system that normally protects our respiratory system.
It also creates irritation and inflammation that causes or contributes to mouth breathing.
The use of a heated humidifier "preconditions" the inhaled air so we can better cope with CPAP.
So the answer is yes, it is supposed to heat the air, and that results in increased humidity. The end result is a dual role.
Try turning on the humidifier for 5 minutes or so before you go to bed, and you will see a difference.
