After 60 HBOT sessions, adults pursuing healthy ageing reported better sleep.
Among 180 adults in a healthy-ageing programme, average sleep-quality scores improved from 7.1 to 6.5. Lower scores mean better sleep. This was a modest improvement, with fewer reported sleep disturbances and less daytime difficulty related to sleep. [1]
For someone interested in more restful nights, the useful question is how sleep feels and how it affects the following day.

Two adult studies assessed sleep quality and time to fall asleep.
Doenyas-Barak et al. reviewed records from people who completed 60 sessions. The healthy-ageing subgroup was aged 50 and above and lived independently. Sessions used 100% oxygen at 2 ATA for 90 minutes, with air breaks, five days a week. Participants completed a sleep questionnaire before and after the course. [1]
Uezato et al. assessed 15 adults receiving HBOT for jaw-bone infection, radiation injury, or spinal narrowing. They measured sleep before treatment and within five sessions; nine people were checked again after 20 sessions. A wrist monitor recorded time to fall asleep. Neither study had a group that skipped HBOT. [2]
The healthy-ageing group reported fewer sleep disturbances and better daytime functioning.
The healthy-ageing group reported fewer sleep disturbances and better daytime functioning. Sleep duration, efficiency, and medication use did not improve significantly. The findings are self-reported changes associated with the course, rather than a controlled test of its effect. [1]
In Uezato’s smaller patient study, wrist-monitored time to fall asleep decreased from 10.1 minutes to 6.2 minutes within five sessions. Sleep-quality scores improved, and daytime sleepiness was lower after 20 sessions. Relief from pain may have contributed to the later changes. [2]
These measures address different parts of rest: settling into sleep, experiencing fewer interruptions, and managing the next day. They help explain why adult sleep research is relevant to an HBOT wellness routine.
Better rest is about the night and the day that follows.
Adult studies link HBOT with improvements in reported sleep quality, while the smaller patient study also recorded faster sleep onset. That gives people interested in rest a concrete reason to explore the research.
