The carbon signature of movies

Did you know that the CO2 concentration inside movie theaters could vary significantly based on the type of movie being screened?

I’m not kidding.

If you think about it a bit, you will admit that this should not be surprising.

Many movie theaters will seat more than 300 people for a screening – that’s a lot of people sitting inside a closed room for two hours or more.

If it is a dull and boring movie that makes you yawn, most audience are going to have pretty normal breathing, and if the movie had put some of them to sleep, their breathing is going to be a bit lower than normal. All said, the amount of CO2 inside the theater is unlikely to be super high for a dull movie.

What if the movie in front is a blood curdling thriller that keeps you at the edge of your seats and makes your heart beat like mad? The audience are going to be breathing heavily – and you can bet that no one will be asleep. Under these conditions, the CO2 levels are likely to be quite high.

Quite interesting, isn’t it? Read more the research done on this from .
