There’s definitely something to this. I was recently setting an alarm for 2am because at some point during the night, I’m going to need to pee anyway and I’d prefer to get up for that with four hours left to sleep instead of two - waking up at 4am and having to get up to pee means I won’t be able to get back to sleep but waking up at 2am before I really have to go means I don’t have that alarm anxiety and will not have a problem making it the rest of the night.
