Dr. Zhao Xiaodong
Yellowing of underwear may be caused by several factors:
1. Sweat and body fluids: Daily activities and physiological secretions, such as sweat, urine, or discharge, may lead to yellowing if not cleaned promptly.
2. Bacterial growth: A moist environment promotes bacterial proliferation, especially in the genital area, which may result in the formation of slightly yellow bacterial stains.
3. Hormonal effects: Hormonal changes in women during menstruation or pregnancy may increase secretions, thereby affecting the color of underwear.
4. Improper washing: Excessive use of chlorine-based bleach or insufficient rinsing may leave residues that can cause yellowing of underwear.
5. Fabric fading: Certain materials, especially cotton, may naturally fade and appear yellow after repeated washing.
If underwear continues to yellow and is accompanied by symptoms such as odor or itching, prompt medical consultation is advised.
