We don't suffocate in closed spaces because the air in the space contains oxygen that we need to breathe. As we breathe in oxygen, our bodies use it for cellular respiration and produce carbon dioxide as a waste product. In a closed space, the carbon dioxide levels can rise, but the space is not completely airtight, so there is still some exchange of air with the outside. Additionally, ventilation systems in buildings help to circulate fresh air and remove stale air, preventing suffocation. **
