According to ChatGPT, email apnea is:
A term used to describe the act of holding one’s breath while reading or responding to an email, typically due to anxiety or stress. It can also refer to the habit of checking emails frequently, interrupting natural breathing patterns.
I’ve never noticed it while emailing, but I’ve been paying attention to my breathing while texting, and I’m pretty certain that texting apnea is a thing. Especially when I’m noticing I’m making lots of mistakes, if I stop, look, and listen for a second, I notice I’m holding my breathe.
