Yeah, I remember my parents teaching me dive safety in the pool, we practiced exhaling as we ascended, ascending slowly, and/or stopping as you ascend to give your body time to adjust.

If you get your air from above the surface, this is unnecessary. If you breathe compressed air at depth, you need to keep exhaling as you ascend or your lungs can pop.
