Will orchid blooms come back?

Could you please elaborate on the likelihood of orchid blooms returning? Is it a question of seasonality, or do the blooms depend on specific environmental conditions? Are there any steps a gardener can take to encourage the return of orchid blooms, such as adjusting the light, temperature, or soil moisture? Additionally, is there a typical lifespan for orchid blooms, and how can one tell if an orchid is healthy enough to bloom again in the future?
