The phenomenon of increasing height by 3-5 cm through stretching.

 
  Hi, I had an appointment last week to learn about my posture problems, and I also asked the doctor some additional questions when I went. I'm  writing here to get your opinion as well. While radiological data showed that a friend's growth plates had closed, actual hospital height measurements revealed a permanent height gain of 2.6 to 3 cm (he knows there is a difference in the morning and evening measurements).
When I asked him how he did it, he said he based his work on increasing the water retention capacity of the intervertebral discs. When I asked him how he did it, he said he went swimming regularly twice a week and used height-increasing exercises from a Turkish physiotherapist's YouTube channel. (If you want, I can give you the video; you can try watching it with English subtitles.)

 He said that by doing this regularly for 55 days, he achieved a net gain of 2.6cm, but if he stopped swimming and these exercises, he would return to his old height, meaning he didn't increase his height but unlocked his potential. I think 3cm is a pretty good gain; after all, most people on this forum are considering 7cm femur lengthening, so who could say no to a painless 3cm height? As for why I told the doctor in the first on place at the beginning of this article.
when I told him this story, he said it was possible. But if it's possible, why isn't it mentioned more often? I can't understand that.

 Has anyone tried this when it's certain that the growth plates are closed? I'm curious to hear your opinions (is there anyone who has seen results after a minimum of 2 months, not just 10-15 days?)  As far as I remember, my height is normally 166 cm, but I clearly feel like I reached 169 cm when I went swimming. Maybe I can try to maintain that 169 cm height through exercise for the rest of my life; it's worth it.  Has anyone tried them?

Yes, I agree with what you said, correcting posture, maybe people with typical curves such as hyperlodrosis gains 1 or 1.5m cm, but it doesn't come above, but in this case I mentioned, he didn't spend any effort   to correct the posture, my friend, he only got this gain by using pilates ball and swimming, this elongation was obtained entirely from the joints in the spine, and yes, continuity is required, we agree that he will probably lose the height he gained if he leaves 2 weeks, he gets it now, he said swimming 2 times a week because he got the lengthening he wants, and he said that he yawns 20 minutes in the morning 3 days a week, (he did 10 minutes in the morning and evening for the first 2 months) I think this can be done at least to give 60 minutes a week instead of to thinking about our neurosis

I feel like I should add swimming to my exercise routine. Right now, I'm studying for the university entrance exam in Türkiye, so I don't think I can dedicate the time. I'll try it this summer and share the results here.
