How can a 15 year old increase height?

Upon reaching the age of 15, the growth in height tends to slow down. However, parents should not worry excessively. Implementing natural methods to increase height at the age of 15 can help your child grow taller.

Does height continue to increase at age 15?

The development of bones is the crucial factor determining human height. Our bones are composed of minerals (mainly calcium) and bone cells. Within the body, these cells form bone tissue combined with calcium and various minerals to make bones stronger and longer.

The most significant height growth occurs during the puberty stage, typically between 9-13 years for girls and 9-14 years for boys. During this period, children experience rapid height development. Girls in puberty can gain an additional 8-10cm in height annually, while boys might grow at a rate of up to 15cm per year.

Moving beyond age 15, the rate of height growth tends to slow down. Nevertheless, there’s still a chance for children to grow an additional 2-5cm in height annually until they reach adulthood.

Several factors affect height at age 15, such as:

– Genetics

– Daily dietary habits

– Exercise routines

– Quality of sleep

– Onset of puberty

– Body weight

– Living environment…

Genetics is an unchangeable factor. However, we can influence other factors to improve height for your child as they reach the age of 15.

Natural Ways to Increase Height at Age 15

The average height for girls at age 15 is 159.7cm, while for boys, it’s 170cm. If your child hasn’t reached this mark, there’s no need for excessive worry. Actively applying the following methods can help improve your child’s height.

Drink plenty of water

Providing enough water to the body helps in faster digestion and absorption of essential nutrients required for bone development. Water also nurtures cartilage and maintains smooth joint function, flexibility, while aiding in body detoxification.

The water requirements for 15-year-olds are similar to those of adults, around 2 – 2.5 liters per day. It’s essential to distribute this amount throughout the day rather than only drinking when feeling thirsty. Avoid excessive water intake just before, during, or right after meals as it may affect digestion.

Apart from drinking plain water, mothers can offer their children the following beverages to enhance height growth at age 15:

– Fresh milk

– Soy milk

– Freshly squeezed orange juice

– Strawberry smoothies…

Encourage early and sufficient sleep

This is a safe way to increase height at age 15. To foster comprehensive height growth, cultivate a habit of early bedtime and ensure your child gets 8-9 hours of sleep per day.

Quality sleep is especially crucial for the height development of 15-year-olds. During deep sleep, the pituitary gland becomes active, producing more growth hormones that stimulate prolonged bone development.

To ensure deeper and better sleep, create a quiet, cool, and adequately dark sleeping environment for your child. Discourage TV or phone usage before bedtime. Encourage completing homework early to avoid staying up late, which can hinder height growth upon entering age 15.

Scientific nutrition regimen

Daily nutritional intake significantly influences physical, intellectual development, as well as height for 15-year-olds and other age groups. Besides ensuring adequate water intake, parents should focus on providing a balanced diet containing essential groups of nutrients like protein, carbohydrates, fats, vitamins, and minerals in their child’s daily meals.

The best height-boosting foods for age 15 include:

– Protein-rich foods: These contribute to cartilage, bone, and muscle formation. Abundant sources of protein for children come from foods like shrimp, milk and dairy products, crab, soybeans, meat…

– Healthy fats: Foods containing healthy fats such as oily fish, walnuts, almonds, vegetable oils, aid in efficient vitamin D synthesis in a child’s body, enhancing calcium absorption crucial for bone development.

– Starch-rich foods: For instance, sweet potatoes, wheat flour, turnips, oats, or rice. These not only provide ample energy to the body but also actively support height growth for 15-year-olds.

– Calcium-rich foods: Seafood, milk, cheese, yogurt, egg yolks, bone broth are excellent sources of calcium essential for a child’s height development. This mineral also helps prevent bone density issues and other skeletal problems.

– Vitamin D: Enhances calcium absorption in the body. Vitamin D can be found in foods such as mackerel, egg yolks, shellfish…

– Other minerals: Iron, magnesium, or manganese… can be supplemented through whole grains, red meat, fish, or dark leafy greens to enrich a child’s diet with these minerals.

Altering living environments

Living environments also exert certain influences on height growth at age 15. Children living in polluted environments, exposed to a lot of dust, or frequently subject to passive smoking might experience slower height development compared to those in cleaner environments. Hence, parents should consider changing residence if necessary to provide the best conditions for their child’s height and physical development.

Eliminate bad daily habits

Changing daily habits is also a natural way to increase height at age 15 that not all parents might be aware of. Some parents overly protect their children, confining them indoors instead of encouraging outdoor activities, which can slow a child’s height development.

Additionally, habits like sitting hunched while studying, lying down to watch TV, staying up late, etc., can hinder height development at age 15. Parents should advise their children to eliminate these habits early on to promote better height growth.


Regular exercise every day stimulates the growth of a child’s bones. Physical activity boosts nutrient metabolism, enhances blood circulation, and provides necessary nutrients for bone formation. Moreover, physical activities help children reduce stress and increase the production of growth hormones.

In addition to encouraging children to participate in height-boosting sports like swimming, badminton, soccer, basketball, cycling, you can guide them to practice the following exercises for optimal height development at age 15:

Pelvic bone tilts:

– Lie on your back on an exercise mat. Keep both feet flat on the floor, shoulder-width apart. Relax your arms, placing them straight down along your body with palms facing downwards.

– Use the strength in your legs and arms to push up, lifting your entire pelvic region until your hips, buttocks, and knees form a straight line.

– Maintain this position for 10 counts before lowering down.

– Rest for a few seconds and repeat the exercise another 20 times.

Cobra pose:

– Lie on your side, placing your palm directly under your shoulder. Keep both legs extended straight.

– Inhale deeply. Push your hand down against the floor and slowly lift your upper body until your arms are fully extended. Raise your head slightly backward.

– Hold for 10 seconds to stretch the back muscles.

– Exhale and lower your body down, relaxing.

– Repeat the exercise 20 more times.

Forward bend:

– Stand on the floor and raise both arms straight up.

– Slowly bend the upper body down until your fingertips touch your toes. Keep your knees straight.

– Maintain this position for 10-20 seconds before returning to the starting position.

– Children should perform this exercise about 15 times daily.


Another simple yet effective way to increase height at age 15 is sun exposure. Sunlight provides ample vitamin D for children, aiding in optimal calcium absorption from their daily diet. This is essential material for bone formation and height increase.

The ideal sunbathing time is before 9 AM and after 4 PM when UV ray intensity is low, ensuring safety for your child’s skin. Avoid prolonged exposure when sunlight is harsh, as it can increase the risk of skin cancer.

Use of supplements

Many parents seek height-boosting nutritional supplements for their children to enhance their physique. These supplements promote height growth by providing beneficial nutrients crucial for bone formation, aiding in quick bone development.

If considering this method, thoroughly research before purchasing any product for your child. Prioritize supplements with clear, reputable origins, certified safety, and tested effectiveness.

Maintain a healthy weight

Excess body weight can exert undue pressure on bone joints and affect mineralization and bone development. Therefore, to optimize height development at age 15, children need to control their body weight and strive for a healthy range.

For those overweight or obese, establishing a weight reduction plan involves:

– Reducing fats, sweets, and starches. Increasing fiber intake.

– Enhancing physical activities.

– Drinking plenty of water.

– Limiting snacking.

– Avoiding processed foods.

Avoid using height-inhibiting substances or drugs

For normal height development, 15-year-olds should avoid using substances or drugs that inhibit height growth, such as:

– Alcoholic beverages

– Steroids

– Nicotine in cigarette smoke

– Carbonated soft drinks

– Caffeine…

These are natural, safe, and easily applicable ways to increase height at age 15 for children. To facilitate height growth, children need to maintain a healthy lifestyle, adopt a balanced diet, engage in regular physical activity, and avoid randomly using height-increasing drugs without a doctor’s consent.


Can a 15-year-old still grow taller?

Yes, it’s possible for a 15-year-old to continue growing taller, although the rate of growth might slow down compared to earlier years. Growth plates in the bones might still be open at this age, allowing for further height increase. However, individual factors like genetics, nutrition, exercise, and overall health play significant roles in determining how much taller a 15-year-old might grow.

Does stretching make you taller at 15?

Stretching alone may not directly lead to an increase in height at 15. While regular stretching can improve flexibility and posture, it does not typically affect the length of the bones in a significant way that results in a noticeable increase in height. The primary factors influencing height growth at this age are genetic predisposition and the functioning of growth plates within the bones. Stretching, combined with a healthy lifestyle and proper nutrition, can contribute to overall physical well-being but might not solely influence height increase in teenagers.
