[Vocabulary] "Rest facilities"

[TheAsker]

Hi!

Reading Anne Tyler's 'Vinegar girl' I failed to understand term "rest facilities" in the given context:

"...Their mother—a frail, muted, pink- and-gold blonde with Bunny’s same asterisk eyes—had spent the first fourteen years of Kate’s life checking in and out of various “rest facilities,” as they were called. Then all at once, Bunny was born..."
Is it a euphemism for kind of a brothel? But the mother has a husband, and Bunny was born from him. So my guess sound rediculous.

Thank you for any comments and suggestions!

My guess is they were psychiatric facilities.

Commonly referred to as 'asylums' in the past, although I think the term may have fallen out of favor somewhat today.
