Sick Building Syndrome (SIN)

A variety of symptoms of discomfort and illness experienced by occupants in certain office buildings (including headaches; ear, nose and throat irritations; coughs; nausea; mental fatigue; and general lethargy) linked to indoor air quality. The sick building syndrome has been associated mainly with airtight buildings that have fixed windows, airconditioning or forced ventilation systems, low levels of relative humidity, and a build-up of indoor air pollutants.
