The killer of teenage girls in tight underwear

　　The heart, lungs and large blood vessels are compressed during chest binding, which affects the normal development of the body's internal organs.

　　Chest binding can affect respiratory function. Under normal circumstances, the coordination of chest breathing and abdominal breathing can ensure normal gas exchange in the human body. However, chest binding affects chest breathing, making the chest unable to fully expand, lung tissue unable to fully stretch, and the amount of inhaled air reduced, thus affecting the supply of oxygen throughout the body.

　　Corsets compress the breasts and impede blood circulation, causing blood stasis in the lower part of the breasts, causing pain, breast swelling and discomfort, and even causing nipple retraction and breast dysplasia, affecting bodybuilding and making it difficult to breastfeed in the future.

　　Therefore, we need to repeatedly publicize the dangers of breast binding. Girls should be encouraged to tell their mothers about breast development so that they can receive necessary health care guidance in time.
