I remember when my family treasure was just 3 months old, hugging out to play and meeting acquaintances, everyone loved to tease, take a look, talk. Among them, the most talked about is that this child will definitely be a tall man in the future, and I asked where do you know that you can grow tall? Several people say it looks at the length of the calf.
Whether it is true or not, it is true that many people take the length of these 4 parts of the child's body to judge the future height, and see how many things your baby occupies?
Finger length
The people around them are generally taller, and we take a closer look at their fingers, while the shorter fingers are relatively short. This is because the body parts of the person develop in a certain proportion, and the finger bones of tall people will be correspondingly longer.
Therefore, if the baby's fingers are longer than those of babies of the same age, it is easy to be considered to be the bigger one in the future.
Arm length
Look at the basketball players in the NBA, big long arms, big tall men. When people develop, all parts of the body are also developing, so many people find that when children have longer arms from a young age, they will not be too short in the future.
In addition, the arm is technically called the arm, the baby's arm includes the ulna and humerus, if their growth potential and speed are faster, the height growth will also be synchronized, because the length of the human arms is basically the same as the height.
Therefore, the slender arm indicates that the child's bones are relatively long, and the height is naturally high.
Calf length
Everyone's height is composed of three parts of the human body, namely the head, spine, and lower limbs. The possibility of head elevation is unlikely, and the long growth cycle of the spine is not an important factor in "elevation". Therefore, the key to rapid elevation is in the lower limbs.
A Turkish survey showed that the longer the tibia (calf bone), the taller the person.
Before the child's calf bone line is closed, it is often supplemented by nutrition and exercise, and the probability of growing up is naturally higher. Under normal circumstances, as long as the barefoot length can be measured more accurately, the approximate height of a person can be inferred. If the child's calves are slender, this indicates that his lower limb bones are well developed.
If parents find that their baby's waist is full of legs, then the child is also likely to be tall in the future, after all, people's height and leg length are closely related.
The legs are long and short
Relevant studies have found that the human foot is a relatively rapid part of the body's development, and it is also the earliest part of the development stop. Therefore, the length of a child's feet has a certain degree of correlation with height.
Height and foot length have a rough calculation formula: adult height = 13 years old foot length (cm) x 7±3 cm.
So if mothers find that their babies' feet grow faster, especially if they change shoes more frequently, it will definitely be higher in the future.
Look at the hip plate closed
The above four parts are all estimated to be high or low in the future. But from the perspective of bone development, the key to determining whether a child can grow taller depends on whether the epiphyseal plate is closed.
Hip plate
The epiphyseal plate, also known as the growth plate, is located between the epiphysis and the end of the epiphysis and is a thin plate of wavy cartilage tissue. It is composed of transparent cartilage.
As the bones mature, the epiphyseal plate also stops growing and gradually closes. Once a child's epiphyseal plate is closed, it is completely impossible to grow tall.
A key factor that affects your child's height
Genetic inheritance
"A woman is short and short", which is a commonly heard saying, shows how much genetics affect a child's height.
According to the existing research results, 60% to 80% of the differences in height are genetically determined, while the remaining 20% to 40% are due to acquired factors, including nutrition, environment, exercise and so on.
How to calculate your child's genetic height:
Boy height = (father height + mother height + 13) / 2±5 cm
Height of girls = (height of father + height of mother -13) / 2±5 cm
There are two key periods for children to grow taller, one is the infant period, and the other is the puberty period.
Among them, infants and young children grow faster, generally in the first year after birth can grow up to more than 20 centimeters, the second year can grow 10-12cm tall, the third year can be about 5cm long.
Adolescents grow fastest between the ages of 12 and 15 and between the ages of 10 and 13. Because of this stage, the child's body secretes more growth hormone and the bone tissue grows faster.
Scientific elevation: sleep, nutrition, exercise and posture
Genetic height is affected by genes and is not controlled by human factors, but acquired factors are completely controlled by parents, so scientific elevation should pay attention to ways and methods.
The basis of growing tall is adequate sleep
Sleep has a greater impact on height, because growth hormone is often secreted at night, and if the child is not sleep-deprived, it will affect the secretion of growth hormone, which will affect the child's height development.
According to relevant research and analysis, the two periods with the most secretion of growth hormone are 22:00-1:00 and 5:00-7:00.
Therefore, parents are best to let their children prepare to fall asleep around 9 pm, so as to ensure that they can reach a deep sleep at 10 pm and that growth hormone can be released to a peak.
At the same time, the child should wake up early as much as possible before 6:30, so as not to miss the second small orgasm of the body's growth hormone secretion.
How long should my child sleep?
The National Sleep Foundation has published a standard table of sleep duration:
In the documents issued by the Ministry of Education of the mainland, it is also clearly stipulated that primary school students need to sleep 10 hours a day, junior high school students 9 hours, and high school students 8 hours a day. Of course, this is only a standard, and there are fewer people who believe that they can meet this standard.
Nowadays, children's schoolwork pressure is high, and it is really difficult to sleep to 10 hours at night, so try to take a lunch break as much as possible to make up the sleep time standard.
Ensure balanced nutrition so that children can be steadily elevated
Children who can eat grow faster, so in order for children to grow taller, comprehensive and balanced nutrition is particularly important. This includes proteins, fats, carbohydrates, and vitamins.
Core nutrients for height: calcium and vitamin D
Calcium is an important part of bones, and calcium deficiency can affect bone development and affect height. Vitamin D is an important nutrient for metabolizing calcium, and without enough vitamin D, more calcium supplementation is in vain.
Calcium supplementation: milk, eggs, tofu, nuts, etc.
Vitamin D supplementation: sunbathing, deep-sea fish, etc.
Protein: Animal and plant proteins need to be balanced
Iron supplementation and zinc supplementation: to ensure the growth rate of children, iron supplementation can eat more egg yolks, kelp, seaweed, pork liver and so on. Zinc supplementation can eat more squid, eggs, lean meat and so on.
Moderate exercise can stimulate bone growth
Sports medicine studies have shown that exercise can greatly promote the secretion of growth hormone, so that the child's height potential is fully stimulated, and the growth is higher.
Three sports that favor growing tall:
Jumping sports: long jump, high jump, basketball, etc
Full-body exercises: gymnastics, swimming, skipping rope, etc
Stretching exercises: The most common is chest expansion
Exercise that is not conducive to growing tall:
Weight-bearing exercises: weightlifting, dumbbells, etc.
Correct the poor posture, the child can be taller than 3cm
Your child's height consists of three parts, natural growth + stable stretching of bone gaps + posture correction. Now many children hunch over at a very young age, full of old age, not only affect the image, but also appear very short.
Therefore, while parents give their children calcium supplements, exercise, and sleep supplements, they should not forget to help their children correct their posture.
Avoid your child from looking down at the phone for a long time and showing a posture of head forward.
Avoid children writing homework for a long time, pay attention to the combination of work and leisure, and ensure that they sit correctly when writing.
Correct the child's usual hunchback and tell the child to hold his head high.
Children with O-leg and X-leg go to the pediatric hospital early and are corrected by medical means.
