Yes Namjoon. Proper ventilation decreases the level of Carbon Dioxide in an enclosed space. High CO2 level causes tiredness, sleepiness, and like what you said, down mood. And another, it decreases airborne contaminants and prevent illnesses. For occupational settings, we have the Department Order 224-21, for the guidelines in securing and maintaining proper ventilation in the workplace.
