Morphology

beauty + sleep

The meaning is directly compositional: combining 'beauty' (appearance) with 'sleep' naturally yields the idea of sleep that affects one's looks, so a B1 learner who knows both words can infer it refers to sleep believed to improve appearance. This is a common collocation with cross-linguistic parallels and does not require learning an arbitrary or highly metaphorical sense.

Etymology

Beauty sleep comes from the simple idea that a good night's sleep helps your beauty. People noticed they looked fresher after rest, so beauty sleep means sleep that 'improves your appearance'.
