The first growth peak occurs from birth to around one year old.
The second growth peak is during puberty when height increases rapidly. The fastest period of height growth is during early puberty, with the peak height velocity around 14 years old. Generally, females stop growing in height between 19-23 years old, while males stop growing between 23-26 years old.
Weight - During puberty, both boys and girls experience rapid weight gain, with an average increase of 5-6 kilograms per year. The shape, height, and individual differences in body weight are influenced by various factors. It is not important to focus on being tall or thin, but rather on growing in a healthy way. Uniqueness is beauty!
The beauty of masculinity and femininity - The appearance of secondary sexual characteristics during puberty makes boys more handsome, becoming men, and girls more graceful and beautiful, thanks to the secretion of sex hormones by the gonads.
Secondary sexual characteristics refer to the external manifestations of sexual development. Apart from the reproductive organs being different for males and females, there are significant differences in physique, body posture, appearance, voice, and more between boys and girls.
Now, let's learn about the characteristics of female secondary sexual characteristics and the signs of sexual maturity. In females, the secretion of estrogen during puberty promotes the development of secondary sexual characteristics. Its characteristics include:
Approximately 3-4 years before the onset of menstruation, girls' breasts begin to develop. At this time, there may be a tender lump around the nipple, and even a slight touch can cause pain, which often causes anxiety and fear in girls. However, this change is a necessary part of breast development, and once the breasts are fully developed, the pain will subside. Around the age of 15, the breasts are mostly fully formed, and it is time to start wearing bras. It is important to choose bras made of soft cotton fabric that fits properly and to wear them regularly, washing and changing them frequently.
Another characteristic of female secondary sexual characteristics is the protrusion of the hips and the widening of the pelvis. Additionally, the skin becomes smooth, soft, and delicate, and the body takes on a fuller shape, displaying the beauty and gracefulness of femininity.
