Did you test this hypothesis at the time with a CO2 monitor? Lack of sleep causes headaches, too.

It appears to me that your judgement is based on prejudice against teenage behaviour rather than evidence.

This is exactly why I object to the statement "in reality it was from co2 ppm" without evidence from a CO2 monitor.
A co2 monitor confirmed my suspicion. The problem with co2 monitors, is that it's really impractical to pull one out to check. I'm actually in the process of building one myself that instead sends descrete notifications to my phone if the co2 ppm gets too high.
I later confirmed it, by carrying a co2 monitor with me and noticing every time I get that type of headache, it's because the co2 was too high.
The device I'm building will be attacked to my backpack and connected to my phone via bluetooth so it can push notifications descretely, allowing me to get out of a place where the co2 levels will give me a headache, without the social cost of taking out a co2 monitor everywhere you go.
