Read the whole comment, I think that's addressed. The sleep cycle is a regular maintenance routine. The whole body functions more efficiently with proper sleep. Sleep as a bodily function is not intended to repair serious injury. Otherwise, when people became injured they would fall asleep, except we don't fall asleep when injured. We become hyper vigilant and produce adrenaline. So certainly there's correlation, but the broader picture 'makes sense' and is not counterintuitive
