With the advent of puberty, young girls are more or less shy and overwhelmed. The gradually rising breast is a woman’s second sex symbol, which not only has the function of breastfeeding, but also is an important organ to show the charm of women. According to statistics, the incidence of breast cancer tops the list of malignant diseases in women, and the incidence of other breast diseases is 15%. Therefore, maintaining healthy breasts and avoiding the pain of disease is a goal that requires joint efforts. Correct understanding Correct understanding of breast development is a normal physiological phenomenon that every woman must go through. You should not feel shy, and you should not tighten your breasts too much because of shyness. Pay attention to your posture. Normally, you should walk with your head up and chest out, tighten your belly and buttocks, and not hunch your back with your chest out. Sitting posture should also be chest up and sitting, do not hunch over the chest. When sleeping, it is advisable to take the supine or side lying, not prone. The overall nutrition Do not pursue slimness and excessive dieting or partial dieting. The right amount of fat and protein-rich food can help increase the amount of fat in the breasts and keep them full and round. Appropriate exercise Adolescent girls are lively and active, at this time can be appropriate to do more such as chest expansion exercises, push-ups and chest aerobics to strengthen the exercise of the chest muscles, creating a beautiful chest curve. Massage the breasts properly in the morning and evening to improve the secretion of the pituitary gland through nerve reflexes and promote breast development. At present, breast enlargement and breast products are flooded with advertisements, and many adolescent girls are devoted to the cause of external and pharmaceutical breast beauty, and these products are largely hormone-containing. It is important to know that every woman’s breast has the ability to develop, grow and repair itself. Before the age of 45, it is best not to apply any topical hormones to avoid breaking the body’s original balance thus leading to body lesions, leading to lobular hyperplasia, breast enlargement, menstrual disorders, breast cancer and other diseases. Pay attention to protection During the process of breast development, sometimes there will be slight swelling and pain or itching, do not squeeze or scratch with your hands. Protect your breasts during labor or exercise to avoid injury from impact or extrusion. Wearing a suitable bra Do not wear a bra too early as it may affect the normal development of your breasts. They should be worn only after the breasts are fully developed, but the size and elasticity should be appropriate. Girls are generally 16 to 18 years old, the development of the chest and breasts is close to maturity; use a soft ruler to measure the upper bottom of the breast (after the nipple) and the lower bottom of the breast, the upper and lower distance is greater than 16 cm, you should wear a bra. If you are younger than 16 years old and the distance between the top and bottom of your breasts is greater than 16 cm, you should also wear a bra. If you are younger than 16 years old and the distance between the top and bottom is less than 16 cm, you should not wear a bra. This is because wearing a bra too early is not only detrimental to the breasts in the development stage, but also affects the secretion of milk in the future, but when a bra is not worn after full development, the breasts will sag due to lack of support, and this will happen regardless of the size of the breasts.
