Can Kids Get High After Adolescence? What factors does it depend on?

Perhaps most of us wonder if a child, or even an adult, can grow up after puberty.

We know that boys and girls are different in the way and time they grow up. However, in both adolescence and almost adulthood, they will get the height they need for the rest of their lives.

Many claim that height is not just a matter of inheritance, and that in some ways we can intervene and increase it.

How is this done? How can we increase the height of our adolescent child? Is nutrition just enough? How can we intervene?

Studies show that differences in height are around 60-80% due to genetic predisposition (heredity) and 20-40% due to environmental factors such as nutrition. In many countries, the average height has increased over the last century. If it were solely because of heredity, then that would not have happened.

For most, height will not increase after puberty

Even with a healthy diet, most people will not increase after 18 to 20 years. The graph below shows the growth rate from birth to the age of 20 years.

Why do we stop growing up?

The reason why your height stops growing is your bones, especially growth plates. Growth plates, or epiphyseal plates, are areas of specialized cartilage near the tip of your long bones. Increases in height are mainly due to the elongation of your long bones, as the growth plates are still active, or "open".

Near the end of adolescence, hormonal changes cause hardening or "closure" of growth levels and cessation of bone elongation. Growth plates "close" around the age of 16 in women and somewhere between 14-19 in men. That's why girls get taller, while boys get older.

There are no stretching exercises or techniques that can make you taller

A common myth about height is that certain exercises or stretching techniques can make you tall. Many people argue that activities such as hanging freely on a bar, climbing, and swimming can increase your height. Unfortunately, there is no scientific evidence to support these claims.

Indeed, your height varies slightly during the day due to the compression and decompression of cartilage disks in your spine. By compressing your disks, some of these activities could temporarily increase your height to a very small degree. However, this is not a real height change, as any such change is only temporary and reverses rapidly.

Exercise (including weight lifting) will probably not affect your height

Many worries that exercise, and especially weight lifting, can be detrimental to their height. Some of these concerns specifically concern children and adolescents whose developmental plaques have not been closed.

The cartilage of growth plates is weaker than the mature bone formed during adulthood and can be more easily damaged. However, most studies show that weight training is safe and beneficial at all ages, provided it is properly supervised. Also, studies have shown that weight training before adulthood does not reduce growth.
Most physicians and sports experts also agree that weight lifting does not need to be avoided in children and adolescents. One study asked 500 sports medicine experts whether weight lifting should be avoided until a person's growth plates are closed. 85% of experts said that we do not need to avoid lifting weights, and only 10% said otherwise.

In adults, growth plates are closed and become stronger than they were in childhood. Because of this, the risk of damage to the growth plate is not a serious problem.

Indeed, lifting weights can lead to slight compression of the spinal discs in adults. However, this is reversible and also happens during daily activities.

A Healthy Lifestyle Before Ending Adolescence Can Help You Get To Your Maximum Possible Height

Although you may not be able to substantially change your height as an adult, there are things you can do to reach your maximum height (based on genetic predisposition) in your teens.

All in all, you want to be sure that you are eating enough and that you are not deficient in vitamins or minerals. Although many children eat too much (or too much…), the quality of their diet is often poor.
Calcium and Vitamin D

Because of this, many in modern society are deficient in important nutrients such as vitamin D and calcium. These nutrients are very important for bone growth and general health. Diet calcium alters hormone production in a way that benefits your bones. Vitamin D can also improve bone health.

A great way to combat nutrient deficiencies and promote optimal bone growth is to increase your intake of fruits and vegetables.


Consuming several proteins is also essential for bone health, although some speculate that high protein intake can damage bones. However, a large meta-analysis of individual studies has found that higher protein intake is not harmful to your bones. In fact, it has proven beneficial for the bone density of the spine.

One way to increase your protein intake is to try to consume at least 20 grams of protein per meal. Good sources of protein are eggs, poultry, lean meats, and dairy products. Soybeans and legumes are also good sources.

Not in the cigarette

Other lifestyle choices, such as smoking, could also affect your height during development.

However, it is important to remember that while various lifestyle factors during childhood can affect height, a person's ultimate height is still largely due to his genetic predisposition.
