If your team regularly experiences headaches, fatigue, eye irritation, or a vague but persistent sense of feeling unwell at work – and those symptoms ease when they leave the building – you may be dealing with sick building syndrome.
It sounds like corporate folklore. It isn’t.
Sick building syndrome (SBS) is a recognised condition, documented by the World Health Organisation, in which occupants of a building experience acute health effects linked directly to time spent inside it. No single cause is identified. But the contributing factors are well understood – and most of them are manageable.
The air you’re breathing
Poor indoor air quality is the most common culprit. Modern office buildings are often tightly sealed for energy efficiency, which means inadequate ventilation and a buildup of pollutants including volatile organic compounds (VOCs) from furniture, carpets, cleaning products, and equipment. Carbon dioxide levels in poorly ventilated offices can reach concentrations that measurably impair concentration and cognitive performance – without anyone realising why.
Mould and moisture
Mould growth – often hidden inside walls, under flooring, or within HVAC systems – releases spores and mycotoxins that contribute to respiratory symptoms, fatigue, and immune disruption. It thrives wherever moisture accumulates undetected. A building can look pristine and still have a significant mould problem within its infrastructure.
Chemical load from cleaning products
Counterintuitively, some conventional cleaning products contribute to the problem they’re meant to solve. Harsh chemical formulations release VOCs that linger in poorly ventilated spaces, irritating airways and contributing to the overall toxic load of the indoor environment. Professional cleaning operations increasingly use low-VOC, environmentally considered formulations – not just for sustainability, but for occupant health.
Dust, allergens, and what lives in your carpet
Carpeted offices trap dust mites, pet dander brought in on clothing, pollen, and particulate matter. Without regular deep cleaning, these accumulate to levels that trigger respiratory symptoms – particularly in people with existing allergies or sensitivities. The same applies to upholstered furniture and soft furnishings.
Temperature and humidity imbalance
Environments that are too dry, too humid, or inconsistently temperature-controlled create both discomfort and conditions that favour microbial growth. Humidity below 30% dries out mucous membranes, reducing the body’s natural defences against airborne pathogens. Above 60%, mould and dust mites proliferate.
The productivity cost nobody is calculating
A 2015 Harvard study found that cognitive performance scores were 61% higher in well-ventilated offices with low pollutant levels compared to conventional office environments. Absenteeism linked to poor indoor air quality costs businesses significantly – but because the cause is invisible, it rarely gets addressed directly.
What good facility hygiene actually addresses
A professional cleaning and hygiene programme does more than remove visible dirt. Properly executed, it reduces airborne particulate matter, manages moisture, controls microbial growth on surfaces, and uses products that don’t compound the chemical environment. Combined with HVAC maintenance and considered ventilation, it forms the backbone of a healthy indoor environment.
Your building should be an asset to your team’s performance – not a liability. If the space people work in is quietly undermining their health and output, the cost is real, even if it never appears on a single line of your accounts.
Red Alert Service Solutions provides professional cleaning and hygiene services designed around how buildings are occupied and used – because the healthiest environments don’t happen by accident.
