Researchers looked back at medical records to see if hyperbaric oxygen therapy (HBOT) might affect sleep quality. They studied 395 patients who had already completed 60 HBOT sessions for different reasons: 180 for healthy aging, 92 for long COVID, and 123 for PTSD. All patients had their sleep quality measured using a standard questionnaire before and after their treatment course.
The main finding was that sleep quality scores improved significantly in all three groups of patients after completing the HBOT sessions. The improvement was statistically strong, but the study did not report exactly how much better sleep became for the average person. The research did not mention any specific safety concerns or side effects related to the therapy in this group.
It is important to be careful with these results for two main reasons. First, this was a retrospective study, meaning researchers looked at past records rather than planning the study in advance. Second, there was no control group of similar patients who did not receive HBOT for comparison. Without a control group, we cannot know if the sleep improvement was truly due to the therapy or other factors.
Readers should understand this study shows an interesting link between HBOT and better sleep reports in these specific patient groups. The findings suggest this connection deserves further study in more carefully designed research. This single study does not prove HBOT is an effective sleep treatment, and people should not start this therapy solely for sleep problems based on this evidence.
