What happens if you stop breathing for 1 minute?

That changes the concentration of free hydrogen ions, which makes these cells more excitable, leading to abnormal functions. For most people, it's safe to hold your breath for a minute or two. Doing so for too much longer can decrease oxygen flow to the brain, causing fainting, seizures and brain damage.
