Yes, growing 5 cm after 17 is possible but depends on your growth plates; if they're still open (common in males until 19, females often by 16), you might, but growth slows significantly, so a healthy lifestyle (sleep, diet, exercise) supports any remaining potential, though dramatic growth isn't guaranteed as most stop by 18-20. A doctor can confirm if growth plates are closed with a bone-age X-ray.
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.
Height almost never increases after the age of 18:
The reason why height stops increasing is because the bones, specifically the growth plates in the bones, stop being active. The growth plates, also known as epiphyseal plates, are specialized areas of cartilage near the ends of long bones.
Some adolescents will grow at a slow steady rate over a two year period while others will experience spurts of rapid growth where bones can grow 2-5cm over one to two months. Girls can grow up to 8cm in a year between the ages of 11 and 14 years, and boys tend to grow up to 10cm a year between 13 and 16 years of age.
However, once the growth plates in the bones close, a person will generally not grow any taller. Most people assigned female at birth reach their full adult height by age 14 to 16. Most people assigned male at birth reach their full height by age 16 to 18. It is very unusual for a person to grow after age 18.
Twin and family-based analyses estimate that between 30 and 90% of human height variation is determined by genetic factors, with most estimates towards the upper end of that range (Preece 1996; Silventoinen et al. 2000; Silventoinen et al.
Stunted height growth is primarily caused by severe malnutrition (especially protein, vitamins, minerals) and chronic illness during childhood, but also by hormonal issues (growth hormone deficiency, thyroid problems), genetic conditions, extreme stress/neglect, and certain medications like long-term corticosteroids, all impacting the bone growth plates. While genetics set your potential height, these environmental and health factors prevent you from reaching it, especially if they occur during the critical first 1000 days (conception to age 2).
Running is one type of exercise that can support height growth. When you run, your body produces growth hormones that help with height development. Also, running in the morning sunlight allows your body to generate natural vitamin D, which improves calcium absorption, strengthening bones and supporting bone growth.
No, 5'8” is about average for men.
So, at 5'8”, you're taller than about 90% of women and about 45% of men. In other words, you're like most guys. You're not short.
The upper age limit for starting GH therapy is generally determined by the status of the growth plates (epiphyses) in the bones. Once these plates close—typically around age 14 in girls and 16 in boys—further height increase is not possible.
It's important to maintain a healthy lifestyle by engaging in regular exercise, eating a balanced diet, and getting sufficient rest. Height and Percentiles: Based on CDC data, the average height for 17-year-old boys is around 5 feet 9 inches (175 centimeters).
When Do Growth Plates Close? Growth plates usually close near the end of puberty. For girls, this usually is when they're 13–15; for boys, it's when they're 15–17.
“Males can keep growing as long as their growth plates haven't closed, which usually happens by age 18,” explains pediatrician Joshua Coleman, MD. “But in rare cases, guys can grow a little more into their early 20s.”
Adult height is influenced by genetics, nutrition, and habits, with the human growth hormone released during sleep playing a crucial role in development. While quality sleep is vital for health, no direct link between sleep quality and adult height has been established.
So pregnant teens are growing in knee height but shrinking in stature as a result of weight gain and lordosis, suggesting that limited or no maternal growth occurs.
At age 17, your son is about to start the last stage of their adolescence, that phase between childhood and adulthood. But they are still growing -- literally. Males keep getting taller into their early 20s.
Conclusion. The 24-week jumping exercise intervention can effectively improve the height of short-stature children.
Scientists estimate that about 80 percent of an individual's height is determined by the DNA sequence variations they have inherited, but which genes these changes are in and what they do to affect height are only partially understood.
There is no evidence that caffeine consumption can directly stunt growth. “Caffeine does not meaningfully impact how tall a child gets,” according to pediatric endocrinologist Roy Kim. While coffee can have an appetite suppressant effect, a tie between that and hindered growth has never been proven.
The best predictor of a child's height is their parents' height or, more specifically, the mid-parental height. The mid-parental height is calculated by adding the mother's and father's height, adding 13 cm (5 inches) for boys or subtracting 13 cm (5 inches) for girls, and then finally dividing by 2.
Genetics is the main contributor to height, but nutrition can play a small role. Some research indicates that certain foods can boost height, especially when an infant or child is malnourished and dealing with growth stunting. Some key nutrients that benefit height include protein, zinc, and vitamin D.
The answer is no, not directly. Exercise cannot change your genetic height potential or physically lengthen your bones. However, it plays a significant role in supporting overall growth and development, especially during the formative years.
