Therefore, summer vacation is also a good time for teenagers to grow taller. Smart parents can only seize the good opportunity to grow up in summer and let their children's height "leap" in the summer vacation if they achieve "three good things and one foot" the day after tomorrow.
Summer vacation is hot, with long days and short nights. In addition, although there are make-up classes in the summer vacation, the children's academic pressure is still not as great as when they went to school. It is easy for children to break the previous routine and form the habit of "don't want to sleep at night and don't think about it in the morning". Children's irregular sleep will cause disorder of hormone secretion in the body and affect their growth.
Research shows that:
Children who sleep more than 10 hours a day are significantly taller than children who sleep less than 9 hours a day.
Because the hormone that can stimulate the human body to grow taller is mainly growth hormone, and the most exuberant time of growth hormone secretion is from 20: 00 to 7: 00 at night, which is five times that of daytime secretion in deep sleep at night. Therefore, during the summer vacation, we should do the following:
? Get enough sleep. Go to bed early and get up early every day, and ensure more than 8 hours of sleep every day.
? Keep calm before going to bed. When the brain is excited, it will inhibit the secretion of growth hormone. Therefore, watching TV or playing games should end 2 hours before going to bed, and don't take an overheated or too cold bath before going to bed.
? Eat less sweets before going to bed. Don't eat supper before going to bed, especially sweets will raise blood sugar level and inhibit growth hormone secretion.
? Drink less water and drinks before going to bed. In order to avoid frequent urination at night and interfere with normal deep sleep.
During the summer vacation, children's work and rest may be disrupted, three meals a day may be irregular, and many children's snacks are also unrestrained. In the past holidays, children not only didn't grow taller, but gained a lot.
Therefore, eating well, eating more, eating correctly and eating in a balanced way are the keys to help in summer. Nutrition is the basis of ensuring height. The quantity and quality of diet will affect the growth of children. Scientific and reasonable nutrition can make children grow 2-3cm tall every year. Therefore, we should pay attention to the following points in height and nutrition in summer.
? Calcium. Calcium is a heavyweight element that constitutes bones. According to research, within half a year, the height of primary school students who drink milk is 0.72 cm higher than those who don't drink milk. Vitamin D contributes to the absorption and utilization of calcium, so we should also pay attention to the intake of vitamin D.
? Protein. Protein is the most needed nutrition for growth. Fish, shrimp, meat, milk and beans are rich in protein.
? Vitamins A, B, C and D can promote the synthesis of protein in vivo. Therefore, if you want to grow taller, summer is a season rich in fruits and vegetables, so you must pay attention to eating more fruits and vegetables.
? Stay away from supplements. Most supplements contain different levels of hormone components, which can lead to obesity and early development. Premature development will promote the premature closure of the epiphyseal line and affect the height of the body.
According to a 9-year follow-up study of 7 16 9- 18-year-old children by foreign child psychologists, it is pointed out that girls who feel nervous are 5.08cm shorter than girls who feel happy, but women who are not tall 157cm are more than twice as likely. The probability of being higher than 162cm will be reduced by 5 times.
Therefore, everyday children should listen to more cheerful songs, watch more positive TV, movies and books, always remember to read Eggplant, learn to talk when encountering troubles, and keep an optimistic attitude.
Sunny summer is also one of the most effective ways for children to do outdoor sports to help them grow taller. This is because the main reason for human growth is the growth of epiphyseal cartilage at both ends of long bones. Appropriate increase in exercise can promote blood circulation, stimulate epiphyseal cartilage through mechanical friction, and make epiphyseal chondrocytes proliferate. At the same time, it can increase the secretion of growth hormone in the body and make bones develop faster. However, exercise can promote the body.
According to statistics:
Teenagers who often take part in physical exercise can be about 4 cm taller than those who don't.
The main sports to promote physical development are:
Bouncing movement
Such as skipping rope, high jump, running and other sports, stimulate the rapid proliferation of long bone cartilage plates in limbs;
Stretching exercise
Horizontal bar pull-ups, aerobics, etc. It helps to stretch the long bones of the spine and limbs;
Full-body exercise
Such as basketball, volleyball and swimming. It is beneficial to the secretion of growth hormone and increase appetite;
