Q: Both parents are tall. How can children be short?
A: Not necessarily, children are likely to be tall, but not absolutely. Otherwise, according to this [high] theory, there should be many [towering giants] from the day when human beings existed until now.
Q: Both parents are short. Is the child not tall?
A: Not necessarily. Pan Changjiang does not have a 1.62 meter daughter.
Q: Parents have [the cutest height difference]. Who is the height of the child?
A: With… Random.
Parents jointly decide about 70% of their children’s height.
Dragon begets dragon, phoenix begets phoenix, and mouse’s son can make holes.
Heredity does have a great influence on height, and there are many genes related to the height of offspring. However, mothers said they did not want to carry the pot for the time being.
According to some current studies, parents have the same genetic influence on their children’s height.
Therefore, there are various online prediction formulas to calculate the height of children according to the height of parents, such as:
Boy Height (cm) = (Father Height + Mother Height + 13)/2
Girl’s Height (cm) = (Father’s Height + Mother’s Height-13)/2
Boy’s height (cm) = (father’s height + mother’s height) × 1.08/2
Girl’s Height (cm) = (Father’s Height + 0.923 × Mother’s Height)/2
These formulas are obtained after statistical research and processing in different regions and different populations.
Therefore, not everyone can fully meet these height prediction formulas.
Moreover, these formulas ignore the influence of factors other than heredity on children’s height and are only suitable for making a very rough prediction.
If you want to grow taller, but you don’t have what’s genetic advantages, then diet, sleep, exercise and psychology are the acquired factors that need to focus on struggle.
Height, 7 days doomed, 3 points by hard work.
Key One: Diet
The cleverest housewife cannot cook a meal without rice.
When it comes to nutrition related to growth, calcium is probably the first thing that comes to mind, because there has always been a saying that “one cup of milk a day makes a nation taller”.
Milk is indeed a good calcium supplement food. Calcium deficiency will also affect growth, but this does not mean that calcium supplement can help grow taller.
Excessive calcium intake may also increase metabolic burden and affect appetite. Under the condition of ensuring calcium intake, attention should also be paid to the balance of other nutrients to avoid nutrition [partial discipline].
It is not only [skinny] that malnutrition is called, but also obesity. They are all easy to affect growth and development.
In short, don’t be too fat or too thin, eat less desserts, drinks and snacks, especially don’t eat all kinds of health products and supplements at sixes and sevens.
Some supplements and health care products may contain ingredients to promote development, which may make children look faster in the short term, but it is likely to lead to early development and epiphysis closure.
This is tantamount to encouraging the growth of seedlings, resulting in a height lower than that of other children, or even a height that had potential to reach.
Key 2: Sleep
The influence of sleep on height is mainly through growth hormone.
The secretion of growth hormone during the day is very small, most of which is secreted after falling asleep. Generally, it reaches a peak about 1 ~ 2 hours after falling asleep, and the secretion is about 3 times that during the day.
Lack of sleep will affect the secretion of growth hormone.
Generally speaking, newborns need to sleep for 14-20 hours a day, 12-14 hours for 1-3 years old and 11-12 hours for 4-6 years old.
The document issued by China’s Ministry of Education clearly stipulates that primary school students need to sleep 10 hours a day, junior high school students 9 hours and senior high school students 8 hours.
Key 3: Sports
Life lies in sports, and it is natural to grow taller without sports.
Reasonable exercise can stimulate the secretion of growth hormone, promote the formation and development of bones, increase the length of bones, increase appetite and improve sleep, thus maximizing the genetic potential.
The World Health Organization believes that children and adolescents aged 5 to 17 should accumulate one hour of moderate to high-intensity physical activity every day, at least three times a week, and recommends aerobic exercises such as fast walking, jogging, rope skipping and swimming.
Exercises like this can stimulate bones for a long time, continuously and rhythmically to help grow up.
What, too busy studying to exercise? Believe me, studying for 45 minutes or getting up for 1 hour and exercising for 10 minutes can easily meet the above requirements.
Key 4: Psychology
Some studies have also found that emotional or psychological disorders can also affect height.
If you grow up in an environment that lacks the warmth of your family and do not receive sufficient care, then your height is usually shorter than that of children of the same age, which is called “emotional interruption short stature” abroad.
However, once these negative psychological factors are relieved, most children can return to normal growth speed.
Can you grow taller as an adult?
There are two key periods for height growth. Losing at the starting line often affects the final height.
The infant period of [one day at a time] is the first critical period for growing taller.
This stage of growth is extremely rapid and is the fastest period in one’s life: the growth can reach 25 cm in the first year after birth, 10 ~ 12 cm in the second year, and about 8 cm on average in the third year. In these three years, it can increase by 45 cm.
It is equally important to seize puberty as a [sprint before the finish line].
Usually, girls start at the age of 10-12 and boys start at the age of 12-14. The height will suddenly increase during puberty. The annual growth rate can reach 7-8 cm per year, and the speed can reach 10-12 cm.
This sudden increase can last for about 1-3 years, and the growth rate will gradually slow down after girls are 13 years old and boys are 15 years old.
As for whether you can still grow taller as an adult… isn’t there a saying that [23, jump up and jump up]?
The generation that put forward this statement did have the possibility of malnutrition due to material shortage, but it is relatively small for the children who have no worries about food and drink now, so don’t miss life because of this statement.
