We should first mention the importance of consulting with your general practitioner for a proper diagnosis of your symptoms as the health problems associated with an allergy to biological pollutants are a lot like those of numerous other ailments. However, your doctor may find it helpful to know your answer to the following questions:
Have you recently had your humidifiers or air conditioning units cleaned and changed the filters, or has it been some time?
Is there a problem in your home with pests like cockroaches, rodents, or other insects?
Have you recently had any energy conservation work done in the home such as insulating, weatherstripping, or the installation of storm windows, etc.? Did you begin to experience your current health issues before the work was done? Have you just moved to a new home and, if so, did your symptoms only start after the move?
Are there high levels of humidity indoors? Can you smell moldy or musty odors that would be a sign of water intrusion? Have you noticed that water often gathers on hard surfaces?
If you are suffering from tiredness, headaches, stuffy nose, fever, dry throat, and trouble breathing, etc., would you say these symptoms tend to disappear when you spend time out of doors?
If the answer is yes to any or all of these questions, then bio pollutants may be affecting you, so this is a good thing to discuss with your GP.
