Putting the miracle growth pills aside and other scams, what are some ways to grow taller after your growth plates have closed? I heard of people grow taller by stretching/aligning their spine due to their bad posture/scoliosis and I do have a slight hunchback due to slouching.
That's pretty much the only thing you can do other than keep straight posture. I wish I had 2-3 more inches on my height and my proportions would've looked nice. My biggest regret is not doing sports when I was 14 and I bet I could've grown to 5'10 to 5'11. Shit sucks that my parents didn't marry taller people.
If you aren't around 23 or something, maximize the quality of your nutrition as best you can. There is some modest evidence (height science, unfortunately, isn't particularly investigated) that certain kinds of stretching may help, but only during the period of height growth. Avoid foods that likely have estrogens left in them, potentially milk is one of these. Estrogen seals the growth caps faster, generally.
The stretches you want to do are like the hurdler stretch. This seems like mainly a hamstring stretch but also stretches the spine.
Aside from that, just my personal recommendation, but stretch the iliopsoas as well. It is anchored at one end to the lower spine. If it doesn't help you grow taller, it will at least be preventative of certain types of back pain, and will prevent the "stomach bump" that you can get from the muscle being tight and pulling the lower spine forward to an unhealthy position (this can also affect digestion negatively, as that area is where the intestines are).
Good luck OP
1% no malnutrition at any point in life
1% not being seriously sick as a child
so breaking bones or wearing plateaushoes
AND MOST IMPORTANT
a Correct Stance "gives" you a few inches and more charisma
Testosterone also helps seal it faster, that's why people who come in puberty later tend to be taller than those who hit puberty early. Of course, it varies from person to person, but that's the general consensus. I came in puberty late and my voice didn't stop cracking until I was around 16-17. I'm 6'3.
just a medical doctor and so a man of science
fighting against filthy lies
testosterone will initiate the growth at begin of puberty, together with some other hormones, but in a later phase it will end it => genetics
in general taller people tend to go trough puberty later than smaller people
