What would be a negative outcome of inadequate ventilation in occupied spaces?

Inadequate ventilation in occupied spaces can lead to various health issues for occupants, making it a significant concern in building design and maintenance. When there is insufficient airflow, harmful pollutants, allergens, and carbon dioxide levels can build up, creating an unhealthy environment. This can lead to symptoms such as headaches, dizziness, fatigue, respiratory issues, and other health problems. Proper ventilation helps to dilute these contaminants and brings in fresh air, which is essential for maintaining good indoor air quality. Therefore, the consequence of inadequate ventilation is primarily detrimental to the health of individuals in those spaces.
