What is Sick House Syndrome?

Sick House Syndrome (SHS), also known as Sick Building Syndrome (SBS) in non-residential contexts, refers to a collection of acute health symptoms reported by occupants of buildings, particularly homes, that improve or disappear when they leave the indoor environment. Common complaints include headaches, fatigue, eye irritation, nasal congestion, throat discomfort, skin dryness, dizziness, and difficulty concentrating. These non-specific symptoms arise from poor indoor environmental quality (IEQ), encompassing factors like inadequate ventilation, chemical pollutants, biological contaminants, and physical stressors such as temperature extremes or noise.

In regions like the UAE, where extreme heat drives constant air conditioning use, SHS poses unique challenges. Sealed buildings to maintain cool interiors often trap pollutants, while rapid urbanization introduces construction dust and volatile organic compounds (VOCs) from new paints, furniture, and carpets. Cultural practices, such as burning incense, further contribute to indoor air burdens.

The Rise of SHS Concerns in Dubai's Rapidly Urbanizing Landscape

Dubai's skyline, dotted with over 20,000 high-rises, exemplifies modern architecture tailored for a hot-arid climate. However, this comes at a cost: heavy reliance on central HVAC systems reduces natural ventilation, fostering stagnant air laden with dust from desert sands and construction sites. Expatriates, comprising 88% of the population, bring diverse sensitivities, amplifying vulnerability. Recent reports highlight spikes in respiratory issues linked to indoor pollutants, underscoring the need for localized research.

Global studies estimate SBS prevalence at 20-30% in offices, but residential data in GCC countries lags. Dubai's context—high occupancy density, new builds off-gassing VOCs, and mold risks from occasional leaks—amplifies potential impacts on productivity and healthcare costs.

BUiD's Pioneering Cross-Sectional Study: A First for Dubai

The British University in Dubai (BUiD), a leading institution in engineering and IT, has delivered the first large-scale investigation into SHS in UAE homes. Titled "Sick house syndrome in Dubai: A cross sectional analysis of residential and demographic risk factors," the paper by BUiD alumna Dr. Muna Ali and Professor Bassam Abu-Hijleh was published in the prestigious Building and Environment journal in May 2026.

This collaboration highlights BUiD's commitment to addressing real-world challenges in the built environment, blending academic rigor with regional relevance. As UAE universities like BUiD advance sustainable design research, such studies position them as key players in national health and urban planning initiatives.

Methodology: Robust Data from 543 Dubai Households

Employing a cross-sectional survey design, researchers distributed a validated questionnaire—adapted from the MM040 (Örebro) and EPA tools—to 543 households across Dubai's diverse sectors. This ensured representation from villas, apartments, and varying socio-economic groups. Principal Component Analysis (PCA) clustered symptoms into two patterns, explaining 56% variance, while Multiple Linear Regression (MLR) pinpointed predictors. Field measurements from prior BUiD work complemented findings, validating self-reported data against PM2.5, TVOC, and CO2 levels.

Alarmingly High Prevalence: 48% of Dubai Homes Affected

The study revealed a staggering 48% SHS prevalence, with symptoms frequent enough to impair daily life. Mucosal and respiratory issues dominated Cluster 1 (eye/nose/throat/chest), while Cluster 2 encompassed fatigue, ergonomic strains, neurological effects, and skin problems. This exceeds global averages, likely due to Dubai's pollutant cocktail: desert dust infiltrating AC filters, VOCs from rapid renovations, and humidity spikes promoting mold.

For context, an earlier BUiD thesis by Muna Ibrahim Ali (2019) reported 30% weekly symptoms improving outdoors, signaling persistence or worsening trends amid ongoing construction booms.

Demographic Vulnerabilities: Who is Most at Risk?

MLR identified personal health histories as strong predictors: migraine (OR significant), dust allergy, asthma, eczema, and female gender elevated risks. Arab/MENA nationals faced higher odds, possibly from genetic predispositions or cultural exposures like incense. Age and occupation showed subtler links, with younger adults in high-density sectors reporting more ergonomic/neurological symptoms. These insights call for targeted public health campaigns in diverse UAE communities.

• Dust allergy: Doubles symptom likelihood due to pervasive sand ingress.
• Asthma/eczema: Exacerbated by poor filtration and VOCs.
• Females: Potentially higher sensitivity or reporting bias.

Residential and Building Culprits: From Leaks to Layouts

Building factors proved pivotal: water leakage (mold promoter), new furniture/carpets (VOC off-gassing), residence in Sector 1 (older infrastructure?), attached closed kitchens (cooking fumes), and central HVAC (recirculating pollutants). Surprisingly, split ACs were less risky than centrals, emphasizing maintenance. Visit the full study for detailed odds ratios: ResearchGate paper.

Contextualizing Findings: UAE's Indoor Air Quality Crisis

Dubai Municipality mandates IAQ standards, yet enforcement gaps persist. PM2.5 often exceeds WHO limits in homes, per BUiD field data, driven by AC filters clogged with desert dust. Cultural incense burning adds PM and VOCs. Expat-heavy demographics heighten allergy reports. Comparative GCC studies echo these, with offices showing 58% SBS.BUiD 2019 thesis PDF

Healthcare costs from SHS could run millions annually, impacting workforce productivity in Dubai's service economy.

Policy and Public Health Implications for UAE

The BUiD study urges IEQ regulations: mandatory low-VOC materials, HVAC maintenance protocols, and ventilation upgrades. Dubai's Green Building Regulations could integrate SHS metrics. Public awareness via campaigns targeting high-risk groups—e.g., allergy sufferers in Sector 1—is vital. For UAE universities, this underscores interdisciplinary research in engineering-health nexus.

Practical Solutions: Mitigating SHS in Dubai Homes

Homeowners can act: regular AC filter changes (monthly in dusty seasons), HEPA purifiers, low-VOC furnishings, exhaust fans in kitchens/bathrooms. Avoid incense indoors; opt for natural ventilation during cooler evenings. Professional IAQ audits, promoted by BUiD experts, detect leaks early.

• Upgrade to energy-efficient AC with fresh air intake.
• Humidity control below 60% to curb mold.
• Plants like snake plant for natural filtration.
