the claim

Polyphasic sleep improves memory.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Polyphasic sleep improves memory?

Partly. One military report indicates working memory benefited from naps, and a 2019 adolescent study found daytime naps aid memory consolidation, but a forum answer speculates polyphasic cycles may lower working memory. No item directly tests whether polyphasic sleep improves memory.
