Zespół chorego budynku
Patofizjologia i mechanizm

Zespół chorego budynku (SBS) to zespół niespecyficznych objawów, takich jak podrażnienie oczu, nosa, gardła, zmęczenie psychiczne, bóle głowy, nudności, zawroty głowy i podrażnienie skóry, które pojawiają się u osób przebywających w określonych budynkach i ustępują po ich opuszczeniu. Patogeneza SBS jest wieloczynnikowa i obejmuje ekspozycję na lotne związki organiczne (VOC) pochodzące z materiałów budowlanych, mebli, środków czystości, zanieczyszczenia biologiczne (bakterie, pleśnie, wirusy) rozwijające się w warunkach nadmiernej wilgotności, nieodpowiednią wentylację (np. wentylacja na poziomie 5 cfm/osobę jest niewystarczająca), promieniowanie elektromagnetyczne oraz czynniki psychologiczne, takie jak stres zawodowy. WHO szacuje, że 30% nowych lub remontowanych budynków może mieć IAQ wystarczająco złą, by wywołać objawy SBS. Objawy częściej występują u kobiet i pracowników biurowych, zwłaszcza w budynkach z klimatyzacją i słabą wentylacją, przy temperaturach ≥23°C. Wysokie stężenia CO2 negatywnie wpływają na funkcje poznawcze i wydajność pracy.

Zespół chorego budynku (Sick Building Syndrome) – wprowadzenie

Zespół chorego budynku (ang. Sick Building Syndrome, SBS) to termin używany do opisania sytuacji, w której osoby przebywające w budynku doświadczają ostrych problemów zdrowotnych lub dyskomfortu, które wydają się być bezpośrednio powiązane z czasem spędzonym w danym budynku, podczas gdy nie można zidentyfikować konkretnej choroby ani przyczyny12. Dolegliwości mogą być zlokalizowane w konkretnym pomieszczeniu lub strefie albo występować w całym budynku. Charakterystyczną cechą SBS jest to, że większość osób dotkniętych tym zespołem odczuwa ulgę wkrótce po opuszczeniu budynku, choć efekty neurotoksyczne mogą się utrzymywać dłużej34.

SBS redukuje efektywność pracy i zwiększa absencję56. Światowa Organizacja Zdrowia (WHO) oszacowała w 1989 roku, że 30% wszystkich nowych lub remontowanych budynków może mieć problemy z jakością powietrza wewnętrznego (IAQ) wystarczające do wywołania objawów SBS78.

Epidemiologia zespołu chorego budynku

Objawy SBS częściej występują u osób pracujących na stanowiskach biurowych niż u osób na stanowiskach kierowniczych, prawdopodobnie dlatego, że osoby na stanowiskach kierowniczych mają lepsze warunki pracy910. Dolegliwości częściej występują u kobiet niż u mężczyzn, co może wynikać z faktu, że więcej kobiet pracuje na stanowiskach sekretarskich, są one bardziej świadome swojego zdrowia lub mniejsza dawka zanieczyszczeń jest potrzebna do wywołania objawów1112.

Badania wykazały, że objawy częściej występują w budynkach z klimatyzacją niż w budynkach z wentylacją naturalną oraz częściej w budynkach sektora publicznego niż w budynkach sektora prywatnego1314. Według Światowej Organizacji Zdrowia (WHO), SBS definiuje się jako: „zbiór niespecyficznych objawów, w tym podrażnienie oczu, nosa i gardła, zmęczenie psychiczne, bóle głowy, nudności, zawroty głowy i podrażnienie skóry, które wydają się być związane z przebywaniem w określonych miejscach pracy”15.

Patogeneza zespołu chorego budynku

Patogeneza zespołu chorego budynku jest złożona i wieloczynnikowa. Badacze wskazują, że w różnych budynkach może występować odmienna kombinacja przyczyn16. Wzorzec występowania objawów, tj. w ciągu dnia pracy i tygodnia, wyklucza możliwość, by problem był związany z infekcją17. Badania wskazują na istnienie kilku głównych mechanizmów patogenetycznych SBS.

Czynniki chemiczne jako przyczyna SBS

Jednym z głównych mechanizmów patogenetycznych SBS jest ekspozycja na zanieczyszczenia chemiczne w powietrzu wewnętrznym. Do najważniejszych należą lotne związki organiczne (VOC), które mogą uwalniać się z materiałów budowlanych, mebli, wykładzin, klejów, środków czyszczących i innych źródeł1819.

Źródła VOC można podzielić na:

  • Źródła zewnętrzne: zanieczyszczenia z spalin pojazdów, wentylacji kanalizacyjnej, wyciągów budynkowych (łazienki i kuchnie) mogą przedostawać się do budynku przez niewłaściwie umiejscowione wloty powietrza, okna i inne otwory. Produkty spalania mogą przedostawać się do budynku z pobliskiego garażu. Radon, formaldehyd, azbest, kurz i farba ołowiowa mogą przedostawać się przez niewłaściwie umiejscowione wloty powietrza i inne otwory20.
  • Źródła wewnętrzne: najczęstszym zanieczyszczeniem powietrza wewnętrznego są lotne związki organiczne (VOC). Główne źródła VOC to kleje, tapicerka, wykładziny, kopiarki, produkty z drewna, pestycydy, środki czyszczące itp. Dym tytoniowy, respirabilne cząstki stałe, produkty spalania z pieca, kominka i nieodpowietrzanego grzejnika również zwiększają zanieczyszczenie chemiczne. Syntetyczne zapachy w produktach do pielęgnacji osobistej lub w produktach do czyszczenia i konserwacji również przyczyniają się do zanieczyszczenia2122.

Określone VOC, uważane za toksyczne zanieczyszczenia chemiczne dla ludzi, są używane jako kleje w wielu powszechnych produktach budowlanych23. Badania wykazały, że niektóre VOC mogą powodować przewlekłe i ostre skutki zdrowotne w wysokich stężeniach, a niektóre są znanymi czynnikami rakotwórczymi24.

Czynniki biologiczne w patogenezie SBS

Zanieczyszczenia biologiczne stanowią kolejny istotny mechanizm patogenetyczny SBS. Obejmują one pyłki, bakterie, wirusy, grzyby, pleśnie itp. Te zanieczyszczenia mogą rozmnażać się w zastojach wody, które zgromadziły się w nawilżaczach, rurach odpływowych i kanałach, lub tam, gdzie woda zebrała się na płytkach sufitowych, izolacjach, dywanach i tapicerce25. Odchody owadów i ptaków mogą również być źródłem zanieczyszczenia biologicznego26.

Zanieczyszczenia biologiczne często wynikają z nadmiernej wilgoci lub wysokiej wilgotności. Warunki te tworzą idealne środowisko do rozwoju i rozmnażania się organizmów żywych, takich jak bakterie i pleśń27. Zanieczyszczenia biologiczne powodują gorączkę, dreszcze, kaszel, ucisk w klatce piersiowej, bóle mięśni i reakcje alergiczne28.

W biurach o dużej gęstości zaludnienia choroby przenoszone drogą powietrzną mogą szybko rozprzestrzeniać się z jednego pracownika na drugiego. Systemy klimatyzacyjne mogą recyrkulować patogeny i rozprzestrzeniać je po całym budynku, np. chorobę legionistów wywołaną przez bakterie legionella29.

Nieodpowiednia wentylacja jako czynnik patogenetyczny

Nieodpowiednia wentylacja jest jednym z najczęściej wymienianych powodów występowania SBS30. W 1970 roku, w wyniku kryzysu naftowego, projektanci budynków zaczęli budować bardziej szczelne konstrukcje, z mniejszą wentylacją powietrzem zewnętrznym, w celu poprawy efektywności energetycznej3132. Wentylacja została zmniejszona do 5 cfm/osobę (stóp sześciennych na minutę na osobę), co okazało się niewystarczające do utrzymania zdrowia i komfortu mieszkańców budynku33.

Wadliwe systemy ogrzewania, wentylacji i klimatyzacji (HVAC) również zwiększają zanieczyszczenie powietrza wewnętrznego34. Nieodpowiednia wentylacja budynku prowadzi do kumulacji zanieczyszczeń wewnętrznych35. W badaniu przeprowadzonym przez Narodowy Instytut Bezpieczeństwa i Zdrowia Zawodowego (NIOSH) analizującym 446 budynków o złej jakości powietrza stwierdzono, że 52% problemów wynikało z nieodpowiedniej wentylacji36.

Zespół chorego budynku jest bardziej powszechny w budynkach z klimatyzacją niż w budynkach z wentylacją naturalną3738. Badania wykazały, że istnieje dość silny dowód na korelację między temperaturami wynoszącymi 23°C i wyższymi a występowaniem objawów3940.

Promieniowanie elektromagnetyczne

Urządzenia takie jak kuchenki mikrofalowe, telewizory i komputery emitują promieniowanie elektromagnetyczne, które jonizuje powietrze4142. Rozległe okablowanie bez właściwego uziemienia również tworzy silne pola magnetyczne, które zostały powiązane z rakiem4344.

Czynniki psychologiczne w patogenezie SBS

Nadmierny stres związany z pracą lub niezadowolenie, złe relacje międzyludzkie i słaba komunikacja często są związane z SBS4546. Stres zawodowy i niezadowolenie są prawdopodobnie ważniejszymi przyczynami objawów niż czynniki fizyczne i chemiczne w środowisku wewnętrznym47.

Występowanie objawów wydaje się być najwyższe wśród pracowników biurowych, wykonujących bardziej rutynową pracę, niż wśród pracowników profesjonalnych48. Postrzeganie przez pracowników presji związanej z pracą, konfliktów zadaniowych i stresorów niezwiązanych z pracą, takich jak wymagania małżeńskie lub rodzicielskie, może wyraźnie prowadzić do subiektywnego doświadczania „silniejszego” podrażnienia w wyniku zachowania chorobowego49.

Inne czynniki przyczyniające się do SBS

Słabe i nieodpowiednie oświetlenie z brakiem światła słonecznego, zła akustyka, słaba ergonomia i wilgotność mogą również przyczyniać się do SBS5051. Te elementy mogą działać w połączeniu i mogą uzupełniać inne dolegliwości, takie jak nieodpowiednia temperatura, wilgotność lub oświetlenie52.

Molekularne i fizjologiczne mechanizmy SBS

Badania nad mechanizmami molekularnymi i fizjologicznymi SBS są nadal w toku, ale zidentyfikowano już kilka potencjalnych mechanizmów i obiektywnych miar wyjaśniających i badających objawy w obrębie poszczególnych układów narządów53.

Mechanizmy alergiczne i drażniące

W przypadku objawów ocznych zaproponowano zarówno mechanizmy alergiczne, jak i drażniące54. Podobnie w przypadku objawów nosowych sugeruje się udział mechanizmów zarówno alergicznych, jak i drażniących55.

Badania sugerują, że SBS może być rodzajem zaburzenia alergicznego, a interleukina-4 (IL-4) odgrywa rolę w rozwoju zaburzeń alergicznych w zmianach ocznych związanych z SBS56. W jednym z badań wykazano, że ciężkość kliniczna SBS korelowała znacząco z odsetkiem komórek T produkujących IL-4 w spojówce, podczas gdy odsetek komórek T spojówkowych produkujących interferon gamma (IFN-γ) nie korelował z oceną kliniczną57.

Wpływ na funkcje poznawcze

Testy neuropsychologiczne wykazały zmniejszoną wydajność w standardowych testach, zarówno w funkcji kontrolowanej ekspozycji, jak i w funkcji obecności objawów58. Wysokie poziomy CO2 w pomieszczeniach wpływają na wydajność poznawczą i zostały powiązane z objawami SBS59. Jeśli stężenie CO2 w biurach jest zbyt wysokie, wydajność pracy pracowników znacznie spada60.

Stres oksydacyjny

Badania terenowe wykorzystujące metody fizjologiczne i pomiary stresu oksydacyjnego mogą prowadzić do lepszego zrozumienia przyczyny SBS61. Nowe badania dostarczyły dodatkowych dowodów na znaczenie reaktywnej chemii i właściwości zapalnych cząstek wewnętrznych dla SBS62.

Diagnostyka zespołu chorego budynku

Diagnostyka SBS jest wyzwaniem, ponieważ objawy są niespecyficzne i mogą przypominać inne problemy zdrowotne63. Nie ma specyficznego testu medycznego, który pozwoliłby zdiagnozować zespół chorego budynku64. Lekarze zwykle leczą objawy indywidualnie, ale prawdziwa identyfikacja „chorego budynku” jest subiektywna65.

Charakterystycznymi wskazówkami sugerującymi SBS są:

  • Zwiększona absencja wśród mieszkańców budynku66
  • Duża liczba mieszkańców skarżących się na niejasne, ale podobne objawy67
  • Wspólna historia ustąpienia objawów, gdy ludzie nie przebywają w budynku6869

Aby objawy mogły pochodzić z zespołu chorego budynku, powinny ustępować wkrótce po opuszczeniu budynku i występować u wielu osób w budynku70. Przy ocenie budynku pod kątem możliwego zespołu chorego budynku najlepiej rozpocząć od obchodu, aby ocenić mieszkańców na dotkniętym obszarze, stan systemu ogrzewania, wentylacji i klimatyzacji (HVAC) oraz zidentyfikować źródła zanieczyszczeń i skażenia71.

Analiza próbek powietrza w celu określenia jakości powietrza wydaje się być logicznym sposobem oceny skarg związanych z „chorym budynkiem”, ale rzadko dostarcza użytecznych informacji7273. Zdecydowana większość lekarzy, niezależnie od tego, czy zgadzają się czy nie, że zespół chorego budynku istnieje jako jednostka medyczna, zgadza się w jednym głównym punkcie: nie ma testów, które mogłyby wiarygodnie zdiagnozować rzekomy zespół chorego budynku74.

Najnowsze badania naukowe nad SBS

Współczesne badania nad zespołem chorego budynku koncentrują się na lepszym zrozumieniu jego mechanizmów patogenetycznych oraz na opracowaniu skutecznych strategii prewencji i łagodzenia objawów75.

Badania wykazały, że zespół chorego budynku może być związany z zanieczyszczeniem pleśnią lub mykotoksynami wewnątrz budynku. Jednak przypisywanie zespołu chorego budynku pleśni jest kontrowersyjne i poparte niewielkimi dowodami76.

Badania nad związkiem między jakością powietrza wewnętrznego a SBS wskazują, że niskie wskaźniki wentylacji są związane z wyższym ryzykiem wystąpienia objawów SBS77. Fisk i wsp. wykazali istotny związek między niskim wskaźnikiem wentylacji a SBS, ponieważ zwiększenie wentylacji naturalnej może kontrolować wilgotność i usuwać zanieczyszczenia wewnętrzne, co jest skuteczną strategią łagodzenia objawów SBS78.

Badania epidemiologiczne również dostarczają cennych informacji na temat czynników ryzyka SBS. W jednym z badań przeprowadzonych w Mogadiszu w Somalii stwierdzono, że mieszkańcy budynków bez funkcjonalnych okien byli prawie czterokrotnie bardziej narażeni na ryzyko rozwoju zespołu chorego budynku (SBS) w porównaniu do mieszkańców budynków z funkcjonalnymi oknami79. Ponadto budynki znajdujące się w bliskiej odległości od zewnętrznych źródeł zanieczyszczeń miały sześciokrotnie wyższe prawdopodobieństwo wystąpienia SBS80.

Badania nad wpływem pandemii COVID-19 na SBS wykazały, że zmiany, jakie COVID-19 wniósł do naszego życia, miały zarówno pozytywny, jak i negatywny wpływ na występowanie zespołu chorego budynku81. W trakcie pandemii COVID-19, która rozpoczęła się w 2020 roku, odkryto, że małe aerozole powietrzne zawierające zakaźne cząsteczki koronawirusa SARS-CoV-2 są głównym sposobem przenoszenia śmiertelnej choroby COVID-1982. Ze względu na swój mały rozmiar, zakaźne aerozole mogą pozostawać w powietrzu przez godziny, zwiększając ryzyko infekcji drogą powietrzną, szczególnie w budynkach ze słabą wentylacją lub niskim wskaźnikiem wymiany powietrza83.

Podsumowanie mechanizmów patogenetycznych SBS

Zespół chorego budynku to złożony problem, który obejmuje interakcję wielu czynników. Główne mechanizmy patogenetyczne obejmują:

  • Zanieczyszczenia chemiczne, w tym lotne związki organiczne (VOC) emitowane z materiałów budowlanych, mebli, wykładzin i środków czyszczących8485
  • Zanieczyszczenia biologiczne, takie jak bakterie, pleśnie, pyłki i wirusy, które mogą rozwijać się w wilgotnych warunkach8687
  • Nieodpowiednia wentylacja, która prowadzi do kumulacji zanieczyszczeń wewnętrznych8889
  • Promieniowanie elektromagnetyczne z urządzeń elektronicznych9091
  • Czynniki psychologiczne, takie jak stres związany z pracą i niezadowolenie9293
  • Czynniki fizyczne, takie jak temperatura, wilgotność, oświetlenie i akustyka9495

Wszystkie te czynniki mogą działać synergistycznie, powodując lub nasilając objawy SBS. Zrozumienie tych mechanizmów jest kluczowe dla opracowania skutecznych strategii zapobiegania i łagodzenia zespołu chorego budynku96.

  • #7 Sick building syndrome (SBS) | Britannica
    https://www.britannica.com/science/sick-building-syndrome
    sick building syndrome (SBS), term applied to a situation in which some or all the people occupying a building (usually working or living in it) experience non-specific health effects such as headache; dizziness; nausea; irritated eyes, nose, or throat; dry cough; or skin irritation. […] These effects may be localized to a part of the building or be present throughout and are usually assumed to be caused by poor indoor air quality (IAQ). […] SBS was first identified in the 1970s, and a 1984 report by the World Health Organization suggested that up to 30% of new and remodeled buildings may have problems with IAQ sufficient to cause health symptoms. Inadequate building ventilation is the most common cause; the appearance of SBS in the mid-1970s has often been attributed to decreased ventilation standards for commercial buildings to increase energy efficiency, following the Arab oil embargo of 1973. Chemical contaminants are also potential contributors to SBS; these include volatile organic compounds emitted by carpeting, upholstery, cleaning agents, and other sources and combustion products including particulate matter and carbon monoxide produced from heating devices such as fireplaces and stoves. Biological contaminants such as molds, pollen, viruses, bacteria, and animal droppings may also contribute to SBS.

    It is difficult to prevent a syndrome if its cause(s), diagnostic tests, treatments, and existence are not clear to a large segment of doctors. However, people may be able to prevent some of their nonspecific symptoms by working with their doctors to treat symptoms. […] The EPA cites World Health Organization (WHO) statistics that indicate as many as 30% of all buildings worldwide that are new or refurbished have air-quality problems. In contrast to sick building syndrome, these problems are identifiable, and most can be remedied by such methods as using HEPA filters to reduce or eliminate most airborne particles, avoiding building air intakes located near sources of vehicle exhaust fumes or other irritants, and avoiding fungal and bacterial contamination of air conditioning or other air circulating methods.

    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. […] Attempts have been made to connect sick building syndrome to various causes, such as contaminants produced by outgassing of some building materials, volatile organic compounds (VOC), improper exhaust ventilation of ozone, light industrial chemicals used within, and insufficient fresh-air intake or air filtration. […] Sick building syndrome has also been attributed to heating, ventilation, and air conditioning (HVAC) systems, an attribution about which there are inconsistent findings. […] Certain VOCs, considered toxic chemical contaminants to humans, are used as adhesives in many common building construction products.

    Sick building syndrome is a condition that occurs when a number of a building’s occupants have a constellation of nonspecific symptoms without a specific identifiable cause, including nausea; irritation of the eyes, nose and throat; mental fatigue; headaches; skin irritation; and dizziness. […] These symptoms should be temporally related to being in the building, resolve when the person is not in the building, and be found in a number of individuals within the building. […] There are many theories as to what causes sick building syndrome. Commonly cited causes are inadequate ventilation, chemical contaminants from indoor sources, and chemical contaminants from outdoor sources. […] Inadequate ventilation is one the most often cited reasons. […] Common chemical contaminants inside the building are found in paint, adhesives, carpeting, cleaning agents, and upholstered furniture. These chemicals can emit volatile organic compounds (VOCs).

    The following are some of the factors that might be primarily responsible for SBS: […] 1. Chemical contaminants […] 1.1. From outdoor sources: Contaminants from outside like pollutants from motor vehicle exhaust, plumbing vents and building exhausts (bathrooms and kitchens) can enter the building through poorly located air intake vents, windows and other openings. Combustion byproducts can enter a building from a nearby garage. Radon, formaldehyde, asbestos, dust and lead paint can enter through poorly located air intake vents and other openings. […] 1.2. From indoor sources: The most common contaminant of indoor air includes the volatile organic compounds (VOC). The main sources of VOC are adhesives, upholstery, carpeting, copy machines, manufactured wood products, pesticides, cleaning agents, etc. Environmental tobacco smoke, respirable particulate matter, combustion byproducts from stove, fireplace and unvented space heater also increase the chemical contamination. Synthetic fragrances in personal care products or in cleaning and maintenance products also contribute to the contamination.

    The term sick building syndrome (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified. […] Inadequate ventilation, which may also occur if heating, ventilating, and air conditioning (HVAC) systems do not effectively distribute air to people in the building, is thought to be an important factor in SBS. […] Research shows that some VOCs can cause chronic and acute health effects at high concentrations, and some are known carcinogens. […] Physical symptoms related to biological contamination include cough, chest tightness, fever, chills, muscle aches, and allergic responses such as mucous membrane irritation and upper respiratory congestion.

    When building occupants are becoming ill from their environment but the exact cause is unknown, its called Sick Building Syndrome. […] Airborne contaminants are usually at the root of Sick Building Syndrome, although the specific cause of the problem may not initially be known. […] Biological contaminants are often the result of excessive moisture or high humidity. These conditions produce an ideal breeding ground for the growth and reproduction of living organisms like bacteria and mold. […] During the COVID-19 pandemic that began in 2020, tiny airborne aerosols containing infectious SARS-CoV-2 coronavirus particles were found to be the primary mode of transmission for the deadly COVID-19 disease. […] Due to their small size, infectious aerosols can stay airborne for hours, increasing the risk of airborne infection especially in buildings with poor ventilation or low air exchange rates.

    During the first energy crisis in the 1970s, builders and building owners took steps to reduce energy consumption in office buildings. Measures included increased insulation, building wraps, weatherstripping doors, and using insulated double- and triple-pane windows, among others. In many cases, buildings were erected or renovated to include windows that couldn’t open, to minimize loss of heated or cooled air. The result: Some modern buildings feel as if they are airtight. […] Many paints, carpet fibers, furniture, and even wallboard off-gas noxious fumes, sometimes for years after installation. These products may emit formaldehyde, acetic acid, or volatile organic compounds (VOCs) and other chemicals. Modern office equipment such as copiers and electrostatic air cleaners add to the problem by adding ozone to the mix. Mold or mildew from damp conditions also create air quality problems. Manufacturing processes and material-handling equipment may add hydrocarbons or smog, and many chemical cleaning agents give off harmful vapors. The result is a chemical stew in the air that makes people ill with sick building syndrome.

    These elements may act in combination, and may supplement other complaints such as inadequate temperature, humidity, or lighting. […] The best approach is to investigate the entire building. […] The initial walkthrough should allow the investigator to develop some possible explanations for the complaint. […] Although air sampling for contaminants might seem to be the logical response to occupant complaints, it seldom provides information about possible causes. […] Solutions to sick building syndrome usually include combinations of the following: […] Pollutant source removal or modification is an effective approach to resolving an IAQ problem when sources are known, and control is feasible. […] Increasing ventilation rates and air distribution often can be a cost-effective means of reducing indoor pollutant levels.

    Sick building syndrome (SBS) is a term used to describe office worker discomfort and medical symptoms that are related to building characteristics, to pollutant exposures and to work organization, and that are mediated through personal risk factors. […] SBS should be simultaneously viewed from and informed by three disparate perspectives. For health professionals, the view is from the perspective of medicine and the health sciences as they define symptoms related to indoor work and their associated pathophysiological mechanisms. The second perspective is that of engineering, including design, commissioning, operations, maintenance and exposure assessment for specific pollutants. The third perspective includes the organizational, social and psychological aspects of work. […] A number of potential mechanisms and objective measures to explain and examine symptoms within specific organ systems have been identified. None of these has a high predictive value for the presence of disease, and they are therefore not suitable for clinical diagnostic use. They are useful in field research and epidemiological investigations. For many of these it is unclear whether they should be regarded as mechanisms, as markers of effect, or as measures of susceptibility.

[…] Inadequate ventilation is a significant contributor to SBS as it compromises indoor air quality, according to the County of Los Angeles Public Health Department. […] Individuals affected by SBS typically experience a range of nonspecific symptoms, according to an article by Dr. Edward Horvath, director of occupational health in the department of general internal medicine at the Cleveland Clinic in Ohio. […] Diagnosing SBS can be challenging, because its symptoms are specific to a particular space and often resemble those of other health issues. […] The primary approach is to avoid or eliminate the root causes, which can alleviate symptoms.

[…] The symptoms of SBS are commonly seen in people with clerical jobs than in people with managerial jobs because professionals or managers have better working conditions. The symptoms are more common in females than in males probably because more females are in secretarial jobs, they are more aware of their health or a lesser dose of pollutants is required to manifest the effects. The symptoms are more common in air-conditioned buildings than in naturally ventilated buildings and are more common in a public sector building than in a private sector building.

    Microwaves, TVs, and computers create electromagnetic radiation that ionizes the air. In addition, extensive wiring that is not correctly grounded also generates strong magnetic fields, which have been linked to cancer. […] SBS is frequently related to excessive work stress or discontent, poor interpersonal interactions, and poor communication. […] Because professionals or managers often have better work conditions, symptoms of SBS are more common in individuals with clerical positions than in those with management positions. […] The symptoms are more prevalent in buildings with air conditioning than in buildings with natural ventilation. Additionally, they are more prevalent in public sector buildings than private ones. […] The symptoms of sick building syndrome usually improve as you leave the dangerous building in question. Persistent symptoms improve if you’ve either eliminated your exposure or addressed risks within the building. Clean air is essential, and with long-term exposure to poor indoor air, the chance of lung disorders such as asthma can increase.

    Noise can contribute to SBS, but in differing ways. […] Lighting has the potential to affect health and comfort. […] Hygrothermal factors include temperature, humidity and air movement, all of which have an effect on the comfort of building occupants. […] Job stress and dissatisfaction are probably more important causes of symptoms than physical and chemical factors in the indoor environment. […] The prevalence of symptoms appears to be highest among clerical staff, with their more routine work, than among professional staff. […] One reason for the lack of an accurate cause or cure for SBS is that the majority of investigations into SBS only look at part of the problem. […] There is evidence that, although SBS does not cause serious damage to health, it does result in potentially problematic consequences.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC2796751/
    The sick building syndrome (SBS) is used to describe a situation in which the occupants of a building experience acute health- or comfort-related effects that seem to be linked directly to the time spent in the building. No specific illness or cause can be identified. The complainants may be localized in a particular room or zone or may be widespread throughout the building. […] The cause of the symptoms is not known. It reduces work efficiency and increases absenteeism. Most of the complainants report relief soon after leaving the building, although lingering effects of neurotoxins can occur. […] The following are some of the factors that might be primarily responsible for SBS: Chemical contaminants, Biological contaminants, Inadequate ventilation, Electromagnetic radiation, Psychological factors, Poor and inappropriate lighting with absence of sunlight, bad acoustics, poor ergonomics and humidity may also contribute to SBS.

    Purpose of review: The aim is to describe recent insight into risk factors for symptoms included in the sick building syndrome (SBS) and to give an insight into preventive work to reduce SBS. […] Recent findings: New studies have added evidence for the role of personality traits and psychosocial work environment, reactive chemistry and the inflammatory properties of indoor particles for SBS. Field studies using physiological methods and measurements of oxidative stress can lead to better understanding of the cause of SBS. […] Summary: SBS is related to both personal and environmental risk factors. In the office environment, SBS may have important economical implications. More focus is needed on the indoor environment in schools and day care centres, hospitals and nursing homes for elderly. Improvements of the home environment may be the most cost-effective way to reduce the burden of indoor exposure. The link between indoor and outdoor air pollution should not be neglected, and the role of energy saving and climate changes will be an important future issue.
