However, there can be lingering effects of various neurotoxins, which may not clear up when the occupant leaves the building. In most cases, SBS symptoms will be relieved soon after the occupants leave the particular room or zone. The key to discovery is the increased incidence of illnesses in general with onset or exacerbation within a fairly close time frame – usually within a period of weeks. Several sick occupants may report individual symptoms which do not appear to be connected.

The WHO has classified the reported symptoms into broad categories, including: mucous membrane irritation (eye, nose, and throat irritation), neurotoxic effects (headaches, fatigue, and irritability), asthma and asthma-like symptoms (chest tightness and wheezing), skin dryness and irritation, gastrointestinal complaints and more. A study in 2017 correlated several inflammatory diseases of the respiration tract with objective evidence of damp-caused damage in homes. Įxtrinsic allergic alveolitis has been associated with the presence of fungi and bacteria in the moist air of residential houses and commercial offices. Exposure to poor lighting conditions has led to general malaise. Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat neurotoxic or general health problems skin irritation nonspecific hypersensitivity reactions infectious diseases and odor and taste sensations. Human exposure to aerosols has been documented to give rise to a variety of adverse health effects.
Signs and symptoms An air quality monitor However, there have been inconsistent findings on whether air conditioning systems result in SBS or not.
Sick building syndrome has also been attributed to heating, ventilation, and air conditioning (HVAC) systems. Īttempts have been made to connect sick building syndrome to various causes, such as contaminants produced by outgassing of some types of building materials, volatile organic compounds (VOC), improper exhaust ventilation of ozone (byproduct of some office machinery), light industrial chemicals used within, or lack of adequate fresh-air intake/ air filtration (see minimum efficiency reporting value). SBS is also used interchangeably with " building-related symptoms", which orients the name of the condition around patients' symptoms rather than a "sick" building. Certain symptoms tend to increase in severity with the time people spend in the building often improving over time or even disappearing when people are away from the building. SBS has also been used to describe staff concerns in post-war buildings with misplanned building aerodynamics, defects in the construction materials or assembly process and-or inadequate maintenance. The outbreaks may or may not be a direct result of inadequate cleaning or inappropriate cleaning methods. A cloud of construction dust released during building rehabilitation, Treasure Garden, Tai Po, Hong Kong. The World Health Organization created a 484-page tome on indoor air quality back in 1984 when SBS was attributed only to non-organic causes, and suggested that the book might form a basis for legislation or litigation. In fact the 1989 Oxford English Dictionary defines SBS in that way.
The main identifying observation is an increased incidence of complaints of symptoms such as headache, eye, nose, and throat irritation, fatigue, dizziness, and nausea. Sick building syndrome ( SBS) is a condition in which people develop symptoms of illness or become infected with chronic disease from the building in which they work or reside.
