Your home's humidity level should be maintained in air conditioned homes to prevent health issues that are associated with dry air. Humidity is the level of water vapor that is present in the air circulating inside the house. Different rooms may have different humidity levels. You can determine your room's humidity level through a device called a hygrometer, which can be purchased cheaply from many discount, hardware, and department stores. With the hygrometer, you will be able to identify which part of the house has poor humidity level.
The Right Humidity Level
Ideally, you should have a humidity level inside your home that ranges from 40 to 50 percent. However, anywhere from 30 to 60 percent would be acceptable.
Issues with Dry Air
If the humidity level inside your house is less than 30 percent, there are many health problems that may develop such as dry throats and noses which often leads to upper respiratory problems. There may also be skin irritations and dryness on people living in the house. Aside from people, things inside the house can also suffer from low humidity. Wood that is installed on various parts of the house will shrink down and the joints on furniture can come loose. There can also be cracks on drywall and plaster if the low humidity is excessive.
