A, bathing with soap is harmful to breast health? If you repeatedly use soap and other cleaning items every night, it is easy to alkalize the local skin of the breast, and the local skin of the breast to re-cover the protective layer, and to restore its acidified environment, it will take some time. Modern medicine believes that there are sebaceous glands and sweat glands on the breast, and the oil on the surface of the breast skin is secreted by the sebaceous glands under the areola. During pregnancy, the secretion of sebaceous glands increases, the sweat glands on the areola also hypertrophy, the nipples become soft, and the increase in secretions of sweat and sebaceous glands also make the skin surface acidification, resulting in softening of the stratum corneum. At this point, if you always use soap-type cleaning items, from the nipple and areola to wash away these secretions, the women’s breast health is not good. The experts pointed out that the frequent use of soap-based cleaning products, through the mechanical and chemical effects of washing away the skin surface of the keratinized layer of cells, promoting cell division and proliferation. If you constantly remove these keratinized layer of cells, it will damage the protective layer of the skin surface, so that the epidermal layer swelling, this swelling is caused by excessive local dryness, bonding and cell shedding of the breast. If you repeatedly use soap and other cleaning items every night, it is easy to alkalize the local skin of the breast, and the local skin of the breast to re-cover the protective layer, and to restore its acidified environment, it will take some time. Soap in the constant alkalization of the skin surface at the same time, but also to promote the proliferation of alkaline flora on the skin, more so that the local acidification of the breast becomes difficult. In addition, washing with soap also washes away the substance that protects the local skin lubrication of the breast – oil. Therefore, in order to fully maintain the local hygiene of the breast, it is best to choose warm water to wash. Second, underwear is not appropriate to affect breast development? Do not wear unsuitable bras, or simply do not wear bras. Choose the right bra is necessary to protect the breasts, do not take it lightly. To choose the right type of bra, you should do the following 3 things: ① Wearing a bra should not be depressing, that is, the bra should not be too small, you should choose a model that can cover all the outer edges of your breasts. ②The straps of the bra should not be too loose or too tight, and the material should be an elastic band that can be loosened a little. ③The distance between the protruding parts of the bra is moderate, not too far or too close. In addition, the material used for the production of bras is preferably pure cotton, not chemical fiber fabrics. Some young girls often do not wear bras, think that the breasts have not grown, so there is no need to wear bras. In fact, if you think wrong, if you don’t wear a bra for a long time, not only are your breasts prone to sagging, but they are also susceptible to external damage. As long as the bra is worn appropriately, it will not affect the development of the breast, beneficial and harmless. Three, long-term side sleep breast asymmetry?

But Director Sun pointed out that this phenomenon need not be overly concerned, with the correction of bad habits, or after repeated effective benign stimulation, the breast will gradually symmetrical. Fourth, the water temperature in the shower is too high or too low to cause breast laxity? The microvessels around the breasts are densely packed, and the stimulation of overheated or too cold bath water is extremely unfavorable, and if you choose to take a sitz bath or a tub bath, you should not soak in too hot or too cold bath water for a long time. Otherwise, it will make the soft tissue of the breast relaxed, but also cause dry skin. Five, excessive dieting to breast dysplasia?

Most of the internal tissue of the breast is fat. The content of fat in the breast increases so that the breast can be developed properly. Some young women, the pursuit of slim, reckless dieting, even every day to vegetarian dishes, the result makes the breast development is not sound, dry and invisible, then other conservation measures will not help. Six, pattern underwear easy to cause skin allergies? The lace, openwork patterns and other lingerie embellishments will undoubtedly make women “shine”, however, too much lace or nylon material can easily cause skin allergies, shedding tiny threads and even into the nipple protrusion, causing lactation disorders or the formation of mastitis.
