| The primary rule to remember when dealing with humidity in confined spaces, is that humidity and temperature are negatively correlated (opposite). For example, the lower the temperature the higher the humidity. In the winter, if the humidity is too low, cool off the room, and humidity will rise. If a room has high humidity, increasing the room temperature will lower the humidity. Obviously turning up the temperature in a room in the summer can be unpleasant, and only partially effective. |
| Warm air can hold more moisture than cool air, so as the temperature rises, the humidty will drop. |  |
| Cool air can hold less moisture than warm air, so as the temperature drops, the humidty will rise. |  |
