Hyperbaric Oxygen has been investigated as a tool to improve sleep quality in those with insomnia. In a study, researchers found that when they administer oxygen, the subjects' brains switch out of active sleep, and remain in a deactivated, slow-wave state the entire time.

These results indicate that HBO2 therapy is beneficial to improve sleep and is safe for children with CP; however, further studies are necessary to explore the mechanisms of HBO2 on sleep.
