Something went wrong. Wait a moment and try again.

If you work in an air-conditioned building with poor ventilation, it can raise your risk of “sick building syndrome.” Symptoms include headaches, dry cough, dizziness and nausea, trouble concentrating, fatigue, and sensitivity to odors. Forced indoor air may also slightly raise your risk of COVID-19. But the CDC says the risk is small. Lower it even more with regular filter changes, opening windows, and covering coughs and sneezes.
