What really matters is whether the sleep interruptions actually matter. Ideally, humans should sleep 4+4 or 3+3 depending on age, not 6,7 or 8.
So, if a person is just getting up to urinate and staying up for long enough for body functions to resume, one should not treat the sleep interruption. On the other hand, if one is waking up gasping for air several times, it is a problem.
There is no evidence that sleep interruptions make any difference. Some people thrive despite having a heavily segmented sleep, and other fare poorly on an uninterrupted 7 hours. We really understand very little, about sleep.
In terms of “gasping for air”? Yes, it is a problem. But the assumption (long-held) that CPAP is more than a band-aid is appearing shakier with each study that comes out. Apnea is potentially deadly. But what to do about it? That is the real question.
One thing that people should look at, seriously. Instead of the very invasive, and very serious, Stanford protocol surgery, a lot of people do very well with functional orthodontic work. But this whole “you have apnea, here is a cpap machine” is really very suspect.
