Around 60 to 80 percent of a person's height is determined by the genes. The remaining 20 to 40 percent is due to environmental factors like lifestyle and nutrition. It is said to be almost impossible to grow height after the age of 18.
During the adolescent period, several hormonal changes take place within the human body. It indeed is good news that an individual During grows 2 to 6 inches taller even after turning 18. Scientists have discovered that the human body is capable to further grow and develop.
Increasing your height after 18 is not possible, even through nutrition and exercise, because the growth plates stop growing. The growth plates (epiphyseal plates) are present at the end of long bones.
In both sexes, height growth continues until the growth plates close toward the end of puberty. Growth plates usually close at 15–16 years old in girls and at 17–18 years old in boys. However, this period can rarely continue until a person is 19–20 years old.
However, once the growth plates in the bones close, a person will generally not grow any taller. Most females reach their full adult height aged 14–16 years. Most males reach their full height by the age of 16–18 years. It is very unusual for a person to grow after the age of 18 years.
In adulthood, when growth is complete, it is still possible to grow a few centimeters. Optimizing your health, adopting healthy lifestyle habits, equipping yourself to work in a good posture or even practicing daily stretching are some of the best practices to adopt.
As mentioned in one of the articles one good way to see if you still have growth potential is to X-ray a wrist- the test is called a Pediatric Bone Age. It will show if your growth plates are still open. A doctor can also request lab tests- checking for hormones- such as thyroid, growth hormone and sex hormones.
The findings show that regeneration of a growth plate occurs when a part of it is injured in such a manner that a bone bridge is not formed between the epiphysis and the metaphysis. Regeneration of a plate is much faster in relation to the growth in length of the bone in the rabbit than in the pig.
On an x-ray, growth plates look like dark lines at the ends of the bones. At the end of growth, when the cartilage completely hardens into bone, the dark line will no longer be visible on an x-ray. At that point growth plates are considered closed.
Stretching And Exercise. Exercise is extremely crucial to gain good height as growth is stimulated when the body is being exercised and stretched. Exercising stimulates the secretion of the growth hormone (4). These exercises will also improve your posture and help you grow at least an inch of height.
It is possible, but the average person is gonna grow an inch (2.5cm) to 2 inches (5cm) from age 16–21: 8cm is possible and more than 10% of males do grow that height from age 16, but well…. not everyone is in the 10%.
They add length and width to the bone. As kids grow, the growth plates harden into solid bone. A growth plate that has completely hardened into solid bone is a closed growth plate. After a growth plate closes, the bones are no longer growing.
Changes in Boys
They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Kids tend to get taller at a pretty steady pace, growing about 2.5 inches (6 to 7 centimeters) each year. When it comes to weight, kids gain about 4–7 lbs. (2–3 kg) per year until puberty starts.
Taking good care of yourself — eating well, exercising regularly, and getting plenty of rest — is the best way to stay healthy and help your body reach its natural potential. There's no magic pill for increasing height. In fact, your genes are the major determinant of how tall you'll be.
Age is obviously a primary criterion in determining if it is possible to grow 10 cm or more. Growth is generally considered to be completed around the age of twenty, at which time the growth plates close. Then it is no longer possible to grow naturally.
Some boys will reach their full adult before age 17, while others may continue growing until age 20 or 21. They'll grow around 3 inches per year during puberty, which typically occurs between ages 9 and 14 for boys.
Well, in fact, you can grow 2 to 6 inches even after the age of 18 or after puberty. Many people think that growing taller after puberty is impossible; however, it can be done with some determination and using the right approaches.
A major growth spurt happens at the time of puberty, usually between 8 to 13 years of age in girls and 10 to 15 years in boys. Puberty lasts about 2 to 5 years.
Overall, there is no evidence that suggests stretching can lead to lasting increases to your height. Your height is mainly determined by your genes and bone structure. And environmental factors like diet and health may also have an effect.
