What does “irse a la cama” mean in Spanish?

A doctor is giving advice about dinner timing, and he keeps lining it up with bedtime: “Si usted se va a la cama a las 9...” — “If you go to bed at 9...” Notice he says irse a la cama, not just “to sleep.” It means the moment you head off and lie down for the night — a common, everyday phrase for your nightly routine.

In the clip: “Si usted se va a la cama a las 9 de la noche, la última comida podría ser entre las 6 y las 7 de la noche.” — “If you go to bed at 9 at night, your last meal could be between 6 and 7.” More examples: “Me voy a la cama, estoy cansado” (I’m going to bed, I’m tired); “¿A qué hora te vas a la cama?” (What time do you go to bed?); “Los niños se van a la cama a las ocho” (The kids go to bed at eight). The verb changes with the person: me voy, te vas, se va, nos vamos. It points to going to bed, not necessarily falling asleep right away.
