Morphology

biorhythm = rhythm (transparent) = bio + rhythm

The word is a straightforward combination of bio- 'life' and rhythm, so the meaning is directly recoverable.

Etymology

Biorhythm comes from bio- 'life' and rhythm 'regular beat', so it literally means the 'life beat'. Think of your sleep and body cycles as a steady beat inside you, which is why biorhythm means a natural biological cycle.
