Chronic symptoms with seemingly no underlying cause can be a sign of SBS. Some of the common symptoms include irritation of the eyes, nose, or throat, dry cough, itchy skin, fatigue, reduced memory or concentration, brain fog, headache, dizziness, nausea, and sensitivity to taste.

Unfortunately, many medical professionals don’t necessarily consider environmental exposures, so these chronic symptoms can be tricky to assign a root cause. Symptoms can also vary widely from person to person. Various factors play a role, including the types of contaminants present, the volume of contamination, genetics, and immune system health.

If several individuals within a household or office are experiencing chronic symptoms, even if they’re not identical, this can point to sick building syndrome. The key is to not normalize or ignore these symptoms.
