Many people notice light patches or discoloration in clothing after laundry, and it often raises questions about the cause. While some assume it’s due to detergents or washing machines, the real reason is usually natural. Health experts explain that this so-called “bleaching” effect is caused by the body’s natural acidity.
Certain areas of the body maintain a delicate balance that helps keep the skin and overall health in check. This acidity, while essential for health, can sometimes affect clothing fabric over time. “When natural acidity is stronger, it can strip dye from clothing, leaving lighter patches,” experts note. This process is normal and generally indicates that the body’s natural balance is healthy.
Not everyone will notice this effect, and that’s also normal. “Some people naturally produce less acidic fluids, which is completely fine,” experts say. Fabric type, color, and dye can also influence how noticeable the bleaching is. While light discoloration is harmless, it’s important to monitor any significant changes in the body’s natural processes.
Health authorities recommend seeking advice if you notice unusual odors, textures, or other changes, as these could indicate a potential issue. In short, unexpected lightening of clothing is usually a normal occurrence. It serves as a reminder that everyday natural processes can sometimes leave visible marks, and there is generally no cause for concern.
