      Uhm. Ackshally, your body can’t detect a lack of oxygen. In a box with no oxygen, you’d likely just peacefully doze off before you (maybe) die.

      What your body does detect is a build-up of carbon dioxide. So if you want to torture someone, prevent them from expelling CO2, or put them in a room full of it.

      Edit: for those downvoting, OP is basically describing a Sarco Pod

        I used to work at a hospital where we needed to make dry ice to send out specimens. The room the dry ice was made in was basically a closet. Hook the CO2 canister up to this little box thing, take the box apart and boom. Dry ice. More than once I noticed my heart beating fast and I couldn’t catch my breath while making the stuff.
