1, easy to be invaded by bacteria.
Underwear is generally cotton, and women have to change it every day. Long-term cleaning of underwear will lead to material deformation, unable to care for the health of private parts, and will reduce the barrier function of underwear.
2, hip deformation
Underwear not only protects the health of private parts, but also plays a role in preventing hip deformation. On the one hand, the reason for hip deformation is gravity; On the other hand, with the increase of age, the passage of collagen will accelerate, and gradually the buttocks will not be as stiff as before, and underwear will play a certain role in shaping. Cotton underwear, with daily cleaning, gradually lost its original elasticity, and it is not as good as new underwear in caring for hip shape.
3, affect the health of private parts
A pair of underwear carries 0. 1 g of feces, plus human excrement, which is sometimes difficult to clean and will accumulate over time. For health reasons, it is recommended to change it every three months. Underwear also has a shelf life. Under normal circumstances, it should be replaced every two to three months, not more than half a year.
Personally, I think women still ignore the replacement of underwear. Many women only change their underwear once every six months or even once a year, thinking that they can still wear it anyway. We should pay attention to our health, after all, health is above everything else.
