If your team is constantly dealing with headaches, allergies, or unexplained fatigue at work, it might not just be bad luck. Your office itself could be making people sick. Sick Building Syndrome (SBS) happens when indoor environments cause persistent health issues, often due to poor air quality, mold, and ventilation problems. The good news? You can fix it. Here’s what exactly to look for and how to make your workspace healthier.
Unexplained Health Issues That Disappear After Work
Ever notice how some symptoms—headaches, dizziness, itchy eyes—show up at the office but seem to vanish once you leave? That’s one of the biggest warning signs of SBS. If multiple employees are experiencing the same thing, your building’s air quality, ventilation, or cleanliness could be the culprit.
Poor Ventilation and Stale Air
When an office feels stuffy or has lingering odors, it’s often a sign of bad air circulation. Modern buildings are designed to be energy-efficient, which sometimes means they’re sealed so tightly that fresh air doesn’t flow in. Without the proper ventilation, pollutants get trapped inside, leading to long-term health issues for the people who spend extended time there.
Dust, Mold, and Hidden Allergens
Just because an office looks clean doesn’t mean it is. Dust collects in vents, mold lurks in damp areas, and allergens hide in carpets and office furniture. Mold, in particular, is a major problem—it thrives in humid conditions and releases spores that can trigger allergies and respiratory issues. If employees frequently complain about coughing, sneezing, or watery eyes, your office may need more than just a quick dusting.
Office Furniture and Equipment Could Be Polluting the Air
New office furniture, carpets, and even printers can release harmful chemicals called volatile organic compounds (VOCs). These invisible fumes can cause headaches, dizziness, and long-term health effects. If your office recently got new furniture or underwent renovations, indoor air pollution might be higher than you think.
Dirty HVAC Systems Spreading Contaminants
Your heating and cooling system should be keeping the office comfortable, but if the filters aren’t changed regularly or the ducts are full of dust, it could be doing more harm than good. Is there a musty smell present when the AC turns on? That’s a big red flag. Regular HVAC maintenance can prevent dust, mold, and bacteria from circulating through the air.

Fluorescent Lighting and Mental Fatigue
Bad lighting doesn’t technically cause SBS, but it sure doesn’t help. Harsh fluorescent lights and flickering bulbs contribute to headaches, eye strain, and general fatigue. Poor lighting combined with bad air quality makes for a draining workspace rather than one that supports productivity.
Infrequent or Inadequate Office Cleaning
A surface-level wipe-down isn’t enough. High-touch areas like keyboards, desks, and shared spaces accumulate bacteria fast. If cleaning is inconsistent or only focuses on the obvious spots, germs and allergens will continue to spread. Deep cleaning carpets, air ducts, and communal areas can go a long way in keeping employees healthy.
How to Fix and Prevent Sick Building Syndrome
The good news? SBS isn’t permanent. With a few key changes, you can make a big difference in your office environment. Improving ventilation, upgrading air filters, choosing low-VOC office materials, and scheduling professional deep cleanings can all help reduce symptoms and improve overall air quality.
