Does Stretching Make You Taller?

No, stretching doesn't make you taller. It can't lengthen your bones or reach the growth plates that decide your height, so your real height stays the same. What stretching can do is loosen tight muscles and improve your posture, which helps you stand at your full height, and any extra length you notice right after stretching or hanging is temporary.

Why stretching can't make your bones longer

You get taller in one place: the growth plates, which are layers of cartilage near the ends of your long bones, like the thigh and shin. During childhood and puberty they keep producing new bone, and then they harden and fuse. Cleveland Clinic notes that girls usually reach their maximum height by about 14 or 15, and boys by about 16 to 18.

How much those plates produce is mostly genetic. According to the NIH's MedlinePlus Genetics, around 80% of the difference in height between people comes from inherited DNA variations. Once the plates have fused, even growth hormone can't add height, as Cleveland Clinic points out.

Stretching works on muscles, tendons and the soft tissue around your joints. That's why you feel looser afterward. Bones don't lengthen when you pull on them, so a stretch can't add a millimeter of bone, no matter how often you do it. To check where you are, see how to tell if your growth plates are closed.

Can stretching make you look taller?

Yes, a bit, and this is where the myth comes from. A sports medicine doctor at Cleveland Clinic explains that relaxing tight muscles and improving posture can help you look taller. Hunched shoulders, a forward head and an exaggerated curve in the upper back all take away from your standing height.

Orthopedic surgeons call slouch-related rounding of the upper back postural kyphosis. It's common in teens and usually straightens when you stand up tall. Exercises that strengthen your back and core and stretch tight hamstrings are part of the usual treatment.

Why you're taller in the morning

Between each pair of vertebrae in your spine sits a cushion called a disc, which contains a lot of fluid. When you're upright, your body weight slowly squeezes some fluid out, and your spine settles a little. When you lie down to sleep, the pressure comes off and the discs recover.

The difference is measurable. In a 2011 study, researchers measured young adults 24 times over 24 hours. Their height changed by about 0.7 inch (1.8 cm) from highest to lowest, and the biggest drop happened in the first hour after getting up.

This is why people swear a stretching session or a night of sleep made them taller. The change is real, but it's the same one everyone gets every day, and it fades by evening. For a fair comparison, always measure yourself at the same time of day, ideally in the morning. More on sleep and height in does sleep make you taller?

Does hanging make you taller?

Hanging from a pull-up bar, or lying on an inversion table, takes the load off your spine for a few minutes. You might measure a hair taller right after. But as soon as you're upright again, gravity starts compressing your spine.

NASA offers a striking example. Astronauts on long missions grow up to 3% taller because there's no gravity pressing on their spine, and they return to their normal height once they're back on Earth. If months of weightlessness don't make the change permanent, a few minutes of hanging won't either. Hanging is still a useful grip and shoulder exercise, as long as you don't expect inches from it.

Does yoga make you taller?

There's no good evidence that yoga increases height. Like stretching, it can improve flexibility, core strength, balance and body awareness, which help you hold yourself up straighter. Poses like a tall mountain pose are useful posture practice. They just don't change bone length.

Stretching and height: myth vs. reality

If you're still growing, the habits that support growth are sleep, food, activity and good health. Our guide on how to grow taller lays them out, and can you grow after 18? covers what's realistic later on.

When to see a doctor

Stretching won't fix a growth problem, so talk to a doctor if:

• You've grown less than about 2 inches (5 cm) in a year before your growth spurt, or you're dropping across lines on your growth chart.
• There are no signs of puberty by about 14 for boys or 13 for girls.
• You're far shorter than your parents' heights would suggest.
• Your upper back stays rounded even when you stand tall or lie flat, you see a hump, or one shoulder or hip sits higher than the other.
• You have back pain that doesn't go away, or numbness, tingling or weakness in your legs.

The takeaway

Bottom line: Stretching doesn't make you taller, but it helps you stand at your full height. Keep the routine for posture and flexibility, and put your growth effort into sleep, food and activity.

Measure yourself at the same time each morning, watch the trend over months rather than days, and you'll get an honest picture of whether you're still growing.
