The danger of wearing a bra for a long time:
The US Cancer Research Center's survey on the relationship between wearing bras and breast cancer shows that wearing a bra that tightens the chest for a long time is not conducive to breast health. Because the breast is bound by the bra for a long time, the blood flow is not smooth, and part of the lymph in the breast cannot flow normally. Over time, the normal cells of the breast will become cancerous. The survey found that the wear rate of breast cancer can reach 75% when worn for more than 12 hours! Women who wear underwear for a short period of time are 21 times more likely to develop breast cancer. Women who don’t take off their underwear at night are more than 100 times more likely!
Therefore, we can wear it without having to wear it at all times.
