Or, the soul king could have gone to sleep at night, and woke up in the morning.

Theres not really anything to suggest he woke up BECAUSE of Juhabach, and considering that the Royal Guard went down to Sereitei to bring Ichigo up there as the Soul King wanted to see him, I think you can safely assume he hasn't been hibernating.
