British researchers have pointed out that female breasts begin to age from the age of 35, when they start to lose tissue and fat, and their size and fullness decline as a result. Therefore, the earlier the prevention of female breast aging, the better.

　　Level 1 Measures: Choosing a well-fitting bra

　　In adulthood, breasts generally do not change much, but they may still change due to dietary structure and physical conditions (e.g. menstruation, pregnancy, etc.). You should always pay attention to the changes in your breasts and choose a well-fitting bra. Wearing tight underwear for more than 18 hours will also affect the detoxification function of the lymph nodes in the armpits, which is not good for your health.

　　Methods: Women should wear the right bra, the choice of fabric, size and design should be as follows.

　　1, fabric: should be selected to cotton or silk and other natural raw materials for the production of fabrics for the bra, chemical fibre synthetic materials, although the appearance of the bra quite cool, but long-term use will affect the health of the breast.

　　2, design: although many bras on the market have steel support, claiming to make the shape more upright, but not necessarily suitable for everyone.

　　3, size: the size of the bra must be consistent with the wearer's bust, too big to play a role in supporting the breasts, too small will make the breasts squeezed, but also affect their development. To choose the right size, the key is to find out the size of the lower bust and the difference between the upper and lower bust, which is to determine the basis of the bra size and cup model. Cup code for the difference between the upper and lower bust, the difference of about 10cm for A cup, the difference of about 12.5cm for B cup, the difference of about 15cm for C cup.

　　Secondary measures: develop good standing and sitting posture

　　Containing breasts is the most damaging to breasts, as it compresses the growth of breast tissue, encroaches on its living space, and easily leads to breast sagging.

　　The 3 wrong sitting postures that make breasts dying:

　　1, leaning on the table

　　Some girls in order to see the computer screen more clearly, like to lean forward on the desk, think so save energy. But this posture is just the right pressure to the chest, will squeeze the fat to both sides of the armpit; lose the content of the lower hemisphere, the results can be imagined.

　　2, leaning crookedly

　　Few people's posture is completely symmetrical, either leaning to the left or to the right. Slight imbalance is of course possible, but because we have to stay in front of the computer for a long time every day, a few hours in one direction to twist, will make the muscles to remember the posture, the spine is also pulled out of the side of the S-shape, resulting in a high and low shoulder, that the breasts naturally also have a high and low, visually caused by a side of the breasts sagging.

　　3, hunchback

　　What is the relationship between hunchback and sagging? The relationship is big. The hunchback's centre of gravity is forward, the upper body is nested, the chest is shrouded in this curve. Moreover, hunchback is often accompanied by round shoulders, shoulders forward slack, equal to the slack chest skin, more can not resist gravity.

　　Method: Maintain a proper sitting and standing posture at all times, and be sure to lift your chest and head.

　　Tertiary Measures: Chest Strengthening Exercise

　　Moderate exercise of the pectoral muscles, breast fat tissue through reasonable exercise part of the conversion into muscle, so that the breast line becomes more upright.

　　Methods: A simple chest exercise is to put your hands together, slowly lift them up, hold them for 10 seconds, and then slowly drop them down to your chest. So repeated 5 to 10 times, up and down movement, can make the breast muscle uplift.

　　Reminder: When exercising, you should wear a sports bra so that you can effectively protect your breasts from being strained during strenuous exercise.

　　Fourth-level measures: frequent massage

　　Through massage can soothe the tightness of the breasts, thus making the breasts more plump and effectively avoiding skin laxity.

　　Methods: Interact with the palms of both hands to hold the bottom of the breasts, gently lift up, and then hold the outside of the breasts to push inward, can avoid sagging breasts and flare.

　　Reminder: Apply some olive oil or natural moisturising lotion when massaging to make the massage smoother and maintain the breast skin at the same time.
