Reasons why children cannot grow taller

Human height growth is affected by different factors, including genetics, nutrition, exercise, sleep, and living environment. Among these factors, genetics only determines a part of human height growth. This means if parents pay proper attention to nutritional supplementation for their children, encourage them to exercise and care for their sleep right from a young age, children can completely possess an outstanding height in the future. However, some habits below might be the culprit of non-growable among children.

Lack of frequent exercising

Exercise is not only good for health but also has a significant impact on growth hormone production. Specifically, when exercising, the organs in the body work better and the nutritional absorption is also more effective, thereby supporting height growth better. However, not everyone has a habit of exercising and that is one of the reasons why they cannot grow taller.

Parents should encourage children to frequently exercise and play sports that are good for height growth, such as basketball, volleyball, football, swimming, pull-ups, jogging, etc.

Less exposure to sunlight

The body needs vitamin D so for calcium can reach the bones. Meanwhile, the most abundant and safe source of vitamin D is the sunlight. According to Science Daily, being less exposed to sunlight also contributes to causing osteoporosis. In particular, if vitamin D is deficient, it will adversely affect the body's calcium absorption, which in turn will lead to stagnant height growth. Therefore, children should be exposed to sunlight for about 15 - 30 minutes per day in the early morning before 8:00 AM.

Staying up late

The growth hormone is secreted most at night from 11:00 PM to 1:00 AM while children are in deep sleep. Therefore, staying up too late will cause the growth hormone level to decline, which significantly affects height growth. You should make sure that your children go to bed before 10:00 PM and sleep 8 hours per day.


Kidney diseases and endocrine diseases, such as hyperthyroidism or impairment of the gonads, are diseases that can affect the bones and make them less healthy due to lack of calcium. Furthermore, diseases also affect the absorption of essential nutrients for the bones, thereby affecting height growth.

High-fat foods consumption

High-fat foods not only cause children to be more prone to obesity and cardiovascular diseases but also reduce levels of vitamins and minerals necessary for height growth. Therefore, instead of feeding children lots of high-fat foods, parents can supplement children with protein-rich foods and calcium-rich foods, such as meat, fish, eggs, milk, mushrooms, and beans to provide energy to children and help them grow taller.

Carbonated soft drinks

Studies have shown that carbonated soft drinks contain a lot of sugar and artificial sweeteners, so drinking too much carbonated soft drinks will affect bone health and bone growth. In particular, bubbles in carbonated soft drinks also cause a reduction in calcium absorption. That's why about 60% of people who often drink carbonated soft drinks will have poor bone growth and joint growth [1].

Researchers believe that carbonated soft drinks not only reduce the body's calcium absorption but also lose the minimum amount of calcium needed for the body due to their phosphoric acid level. Therefore, to supplement the body with essential vitamins to help the height grow, children should drink plenty of water or fruit juices instead of carbonated soft drinks.

High-sugar foods

High-sugar food can increase the risk of obesity and increase the number of bad nutrients in the body, which reduces the absorption of calcium and vitamin D. Therefore, parents should not let children frequently eat high-sugar foods but should feed them plenty of green vegetables and fruits to supplement them with necessary nutrients to grow taller.

Low birth weight

Low birth weight is a critical factor that can significantly influence a child's growth trajectory. Babies born with low birth weight, typically defined as weighing less than 5.5 pounds (2.500 grams) at birth, may face various growth challenges as they develop. This lower weight at birth can be due to a range of factors, including premature birth or maternal health issues during pregnancy.


When a child's immune system is engaged in combatting infections, it shifts its focus from routine growth processes to prioritize defense mechanisms. This heightened immune activity demands additional energy and nutrients to sustain the fight against pathogens, often leading to reduced resources available for regular growth and development.

The impact of infections extends beyond simply diverting energy; these illnesses can also disrupt appetite, leading to decreased food intake and weight loss, which can further hinder growth. Additionally, fever, a common symptom of many infections, can accelerate metabolic rates, increasing the body's demand for energy and nutrients.

Bone disorders

Rickets, commonly associated with vitamin D deficiency, illustrates how vital proper nutrition is for bone health. Vitamin D, calcium, and phosphate are pivotal in maintaining the strength and integrity of bones. A deficiency in any of these essential nutrients can disrupt the bone mineralization process, leading to weakened bones that are more susceptible to deformities and fractures.

Beyond rickets, scoliosis is another bone disorder that can affect growth. Scoliosis is characterized by an abnormal curvature of the spine. While it primarily impacts the spine's alignment rather than bone length, severe cases can lead to postural changes that may affect a child's height perception.

Inadequate caloric intake

Inadequate caloric intake is a fundamental factor that can significantly impede a child's growth, especially during periods of rapid growth, such as infancy, childhood, and adolescence. Calories are the energy currency that fuels all physiological processes in the body, including tissue growth and development. When a child consistently consumes fewer calories than their body requires to support growth, it can lead to several growth-related issues.

Emotional factors

Emotional factors, particularly chronic emotional stress or trauma, can exert a surprising influence on a child's growth trajectory by triggering complex hormonal responses within the body. When a child experiences ongoing stress, whether it's due to family issues, bullying, academic pressures, or other emotional challenges, the body can respond by releasing stress hormones like cortisol and adrenaline. These hormones can disrupt the normal functioning of the endocrine system, which regulates growth.


Understanding the factors that can hinder a child's growth is crucial for parents and caregivers. Poor nutrition, chronic illnesses, hormonal imbalances, lack of sleep, limited physical activity, and exposure to certain environmental toxins can all contribute to stunted growth. Recognizing and addressing these factors early can help optimize a child's growth potential and overall health. It's important to consult with healthcare professionals if growth concerns arise to identify and address any underlying issues.
