The peak of growth hormone secretion in terms of age, growth hormone will be secreted in large quantities in childhood and adolescence, and will decrease with age. According to relevant data, at the age of 60, the secretion of growth hormone is less than 1/4 at the age of 20.
Judging from the time of day, the time of human growth hormone secretion is11at night; 2 a.m. In addition, 9 p.m. and 6 a.m. the next day are also small peak hours.
Therefore, there is a scientific basis for the old man to say that more sleep can make him grow taller.
1. Sleep
As mentioned above, the peak of growth hormone secretion is at night, and the better sleep, the more conducive to growth hormone secretion. On the contrary, poor sleep, staying up late and getting up early will all affect children's growth.
Step 2 be energetic
Insufficient energy supply is also the main factor of the decrease of growth hormone secretion. Hypoglycemia, hunger and excessive exercise lead to insufficient energy supply in the body and affect the secretion of growth hormone. In the past, people didn't have enough to eat, didn't wear warm clothes and were overworked, so their height was also affected.
3. Amino acid level
Amino acids generally come from protein, and protein, also known as the foundation of life, has an impact on metabolism and development such as endocrine, bone and hormone secretion. Protein deficiency leads to amino acid deficiency, and the secretion of growth hormone will also be affected.
Simply supplementing calcium does not mean that you can grow taller. Many parents believe that children are not tall because of calcium deficiency, so in order to grow taller in the future, calcium should be supplemented from an early age. In this regard, Zhang Jing believes that height and calcium supplementation cannot be equated.
Although bone growth needs calcium, calcium is definitely not the main driving force for bone growth. The growth of bones depends on growth hormone, protein and nutrients obtained from food. Children who lack growth hormone will not grow taller even if they have enough calcium, while children who have insufficient total energy and protein intake will not grow taller if they only supplement calcium.
When supplementing calcium for children, Zhang Jing reminded that children over two years old should not advocate too much calcium supplementation, otherwise the bones will calcify prematurely, but they will not grow tall. Only children with low calcium should be properly supplemented with calcium unless calcium deficiency is found. In addition, parents need to pay attention to the fact that infants and young children should supplement calcium in moderation, not as much as possible. Infants and young children consume about 400 mg of calcium every day, while adolescent children are similar to adults and can consume 800 mg of calcium every day. If the intake of calcium greatly exceeds the above standard, it may cause constipation and even interfere with the absorption and utilization of other trace elements such as zinc, iron and magnesium.
In fact, parents must pay attention to the supplementation of other vitamins while supplementing calcium to their children. A reasonable diet is very important.
