Why is air in a sunny park different than air in a office cubicle with harsh bright lights when it is both air? Is it a placebo or a real thing?
In: Planetary Science
The lighting has nothing to do with the air. Indoor air passes through mechanical processors to push it, cool it, warm it, dehumidify, or humidify, depending on needs. Outdoor air is a product of the surrounding environment – pollution, forests, mountains, weather, the sea, a lake, etc. Downtown city air is probably the dirtiest air there is and it smells of auto exhaust, food preparation (oil and smoke), sewers, garbage, while a park outside the city will have the freshest air (provided it’s not beside a garbage dump).
