Why is spring a period of rapid growth?

▼ The fastest growing period in life: infancy and adolescence.

Infancy (0-3 years old): The height of newborns is generally about 50cm, and the height can grow to 75cm by 1 year old. The baby can grow 25cm in this year, and 10-12cm in the second year. , grows 6-7cm in the third year.

Puberty: Boys grow 9-10cm per year, and girls grow 8-9cm per year.

▼ The fastest growing season of the year: spring.

The WHO has statistics: the growth rate of children's height varies in spring, summer, autumn and winter. Spring (March-May) grows fastest, especially in May, and height growth is in autumn ( 2-2.5 times from September to November).

▼ The fastest time of day to grow: after 10pm.

The growth of a child is related to the amount of growth hormone secreted. The period when growth hormone secretion is at its strongest is the height growth period. There are two levels of growth hormone secretion in a day after 10 p.m. Individual "peak period" accounts for 20%-40% of the secretion throughout the day.

In addition to having a certain relationship with the innate inheritance from parents, a child's height is also related to acquired diet, exercise, sleep and other factors. Therefore, if you want your child to be taller, you need to do well in the following aspects:?

1. Diet

On the basis of a balanced diet, eat more rich and rich foods Foods with high-quality protein, trace elements and calcium. Adequate and balanced nutritional supplements are the guarantee for growing taller.

Foods rich in protein: milk and dairy products, beans and soy products, eggs, lean meat, etc.;

Foods rich in trace elements: vegetables, fruits, seafood products, whole grains, etc.;

Calcium-rich foods: milk and dairy products, dark green vegetables, sesame paste, shrimp, etc.

2. Exercise

Growth hormone can be secreted during exercise. Some studies have pointed out that the most growth hormone is secreted during exercise on an empty stomach, which can help children grow taller. Therefore, if you want your children to grow taller, you can exercise moderately before dinner for better results.

Bounce exercise: can stimulate the growth line between the thigh bone and calf bone and promote bone growth, such as skipping rope, jumping, etc.;

Stretching exercise: can promote the secretion of growth hormone, such as Horizontal bar pull-ups, aerobics, etc.

PS: Avoid overloading during exercise, which will damage the child's cartilage and muscles and is not conducive to growth and development.

3. Sleep

A large amount of growth hormone can be secreted during sleep, which helps children grow taller. Try to put your children to bed before 9 pm every day, and between 0-2 am in the morning. In a deep sleep state, more growth hormone is secreted, which is better for growing taller.
