ELI5:Why is controlling your own breathing so uncomfortable?
gpt
because breathing is usually mediated by CO2 levels in the body- CO2 levels rise, and you instinctively breathe out. When you breathe manually, you are ignoring CO2 levels and just breathing when you think you should or need to take a breath, so your bodies CO2 levels are not regulated properly. This is uncomfortable because we don't like CO2.
