“Healthy cleaning” isn’t just a sustainability preference. It’s a risk-reduction and performance strategy for buildings where people learn, work, heal, and live—especially because sensitive populations are common, and indoor environments influence cognition, absenteeism, and staff retention.
Why sensitivities are now a facilities priority
A meaningful share of the population reports adverse reactions to common fragranced products—exactly the kinds of products that often show up in washrooms, corridors, and “freshening” routines.
-
In a multi-country study, ~32% of adults reported health problems from exposure to fragranced consumer products.
-
In a U.S. survey study, ~30% of the general population reported irritation from scented products on others, with notable reported adverse effects from air fresheners and similar exposures.
Sensitivities also overlap with highly prevalent respiratory conditions:
-
8.6% of adults and 6.5% of children currently have asthma (2024).
So when a building relies on strong fragrances, high-VOC products, frequent sprays, or harsh disinfectants as “standard cleaning,” it’s not surprising that some occupants experience headaches, irritation, asthma flare-ups, or reduced tolerance—even when the products are used “as directed.”
The building-performance link: healthier indoor environments improve cognition and attendance
Cleaning choices affect indoor environmental quality in several ways:
-
VOCs and semi-volatile compounds from solvents, fragrances, and some disinfectants
-
Aerosolized droplets from trigger sprays and mists
-
Residual chemistry on surfaces that can re-volatilize
-
Occupant perception and comfort, which drives complaints and distraction
Why that matters: building conditions don’t just affect comfort—they affect measurable human performance.
-
Research from Harvard T.H. Chan School of Public Health found cognitive scores were substantially higher under “Green” and “Green+” indoor conditions, with VOCs and CO₂ independently associated with performance (in a controlled study design).
-
In schools, stronger ventilation has been associated with lower illness-related absences, reinforcing that indoor environmental quality connects directly to attendance.
The takeaway for facility leaders is simple:
If your building strategy includes productivity, learning outcomes, retention, and customer experience, then “what chemicals are in the air” is not a side issue. It’s core operations.
“Green” isn’t automatically safe: why procurement standards matter
Many organizations try to solve sensitivities by switching to “green” products. That can help—but only if you choose the right criteria.
Centers for Disease Control and Prevention has explicitly warned that some products marketed as “natural” or “green” can still contain ingredients that trigger asthma, and points schools to resources for selecting “asthma-safer” products and practices.
So rather than buying based on a label, a healthier cleaning program should be built on measurable constraints, such as:
-
Low/limited VOC content (and avoiding added fragrance when possible)
-
Ingredient hazard exclusions (e.g., sensitizers, persistent pollutants)
-
Avoiding unnecessary spraying/aerosolization
-
Right-sizing disinfection (targeted use where needed, not blanket “everything, all the time”)
The workforce angle: cleaning chemicals can harm the people doing the cleaning
If you’re responsible for ESG, duty of care, or contractor oversight, this point matters:
Occupational evidence has repeatedly linked certain cleaning and disinfecting exposures to respiratory harm.
-
A meta-analysis in occupational settings reported a clear increased risk of asthma among cleaners (quantified in the literature as elevated relative risk).
-
In healthcare settings, systematic review work has examined asthma and asthma-like symptoms among workers exposed to cleaning/disinfecting agents.
-
Large cohort research among nurses has associated disinfectant exposure with adverse respiratory outcomes, and identifies specific chemical classes of concern in the broader evidence base.
This is where “better hiring practices” becomes practical—not abstract.
Better hiring and contracting practices for cleaning services include:
-
Selecting vendors that train properly (dilution, dwell time, ventilation-aware use)
-
Reducing spray/aerosol practices where feasible
-
Providing safer product options and clear SOPs
-
Paying for stability (lower turnover = better adherence and fewer “chemical overuse” workarounds)
-
Tracking incidents and feedback from staff (not just occupants)
Healthier cleaning protects occupants and also reduces work-related risk for cleaning teams, which can affect absenteeism, turnover, claims, and service quality.
Practical accommodations: fragrance policies and communication reduce friction
Sensitivity isn’t only about products; it’s also about policy and expectation-setting.
The Job Accommodation Network notes that fragrance sensitivity can make it difficult for some employees to function, and discusses workplace practices such as fragrance-related accommodations and policy approaches.
Even a light-touch approach often helps, for example:
-
Posting signage for fragrance-free areas (meeting rooms, clinics, classrooms)
-
Asking staff to avoid strong scents on high-occupancy days/events
-
Eliminating fragrance-emitting “air freshener” devices
-
Switching to unscented soap where possible
These policies are inexpensive—and they reduce repeated complaints and “mystery symptoms” that otherwise become ongoing HR and facilities time sinks.
