Since no one has posted it, here’s the article [1] (at least the preprint version)
Two things I noted:
1) While there was an association with increased brain size, no correlation was found with cognitive function
2) This study was done with Mendelian Randomization, where they find a gene that affects how much people nap, without affecting other things that could change the results. I don’t know that much about MR, but maybe someone else could weigh in on how fallible it is in a case like this (how can we know that a gene that affects napping, which is initiated by the brain, doesn’t affect the brain in other ways).

- moffkalast 3y ago> Overall, we observed evidence of an association between genetically-instrumented daytime napping and larger total brain volume, but no evidence of an association between habitual daytime napping and hippocampal volume, reaction time or visual memory. Yeah, this is big brain time. Does this mean that if you take too many naps your brain will eventually inflate so much it'll start pressing onto the skull and give you headaches, or just that people with larger brain volume seem to have more of a tendency to nap?
- e12e 3y agoThanks for that! > While there was an association with increased brain size, no correlation was found with cognitive function. Somehow "Daytime naps cause swelling of brain, no tangible benefits" doesn't sound the same...
