A human body has to get used to the changing water pressure as it descends to deep sea caverns. If you rise too quickly, the sudden change in pressure can damage the fragile human body.

This is why deep-sea fish die when you try to bring them up to the surface(excluding subnautica, because I like my oculi and spinefish aquarium)
