I seem to have this either after a while when in a classroom or office, or even just when having to do admin at home.
After about 30 minutes, I start barely breathing and then after a while I start getting headaches and it becomes more difficult to concentrate.
I very often push through because I don’t really know what to do when I’m in a situation where I still have to stay for hours. like a class.
Any good ways to help with this?


I notice it when talking to somebody (or typing words). I tend to hold my breath while doing so.
