Is there a low volume of oxygen since people in the room consumed it? Or is the air just warmer from all the people?
I hope everyone understands the “breathed out” phrase. I am not native speaker and tried for 10m to find the appropriate English word but wasn’t able to. I mean the kind of situation when you come to the room of people and the air is just bad and you say “Wow the air in here is so bad, I will open the window.”

The average human puts out as much heat as a 100 watt iredecsent light bulb, and unless the room is well ventilated, the air quality will suffer.
I think you’re talking about it being “stuffy”?
Hot and full of carbon dioxide, literally the air has been breathed out. They say it makes people tired after being in a long meeting with no ventilation. I know I’ve almost fallen asleep myself in these
A part of what you feel is the higher carbon dioxide( CO2) level that we breathe out.
Humans cant detect low oxygen levels directly. If the oxygen level drops and carbon dioxide there are some signed to detect it. But even in a test where you know the oxygen level will drop but not exactly when a human sitting still has a huge problem detecting the change and it can result in levels where you fall unconscious without noting it.
There was a test in a TV program “Astronauts: Do You Have What It Takes” episode 4 but I can’t find it watchable on the internet legally. The clip is at [https://www.bbc.co.uk/programmes/p05cgp35](https://www.bbc.co.uk/programmes/p05cgp35) but do not play for me I suspect because of geographical restitution. Many of them failed to detect low oxygen levels and the test was stopped when it reached dangerously low levels.
You can notice low oxygen levels in a simpler way if you tried to do physical activity because you can do a lot less of it and get out of breath quickly. If you travel to a high altitude location it is quite obvious, there you get a low oxygen level but can still get the CO2 out from your body like normal.
Humans can detect CO2 levels in our blood. If you feel you need to breathe is because of high CO2 levels in the blood, not low oxygen
In an enclosed space the CO2 levels will be a problem for humans before lower oxygen level.
But there are other factors too like the temperature of the air and even the smells from the human body. If you enter a room like that from the outside you will notice the smell.
