Why are sanitary napkins prone to moisture and mold, and how should they be stored?
The primary function of sanitary napkins is to absorb menstrual blood. Most materials used in their production also exhibit good water absorption properties, making them prone to moisture absorption from the air. If left in a humid environment prone to bacterial growth for an extended period after opening, they may become damp, moldy, or even attract insects. Therefore, they should be stored in a dry and clean environment. It is recommended to use them within 2 to 3 months after opening to ensure safety.
What precautions should be taken regarding the replacement frequency of sanitary napkins?
The frequency of sanitary pad replacement depends on multiple factors, including menstrual flow volume, usage time (daytime or nighttime), and activities such as meetings or outdoor engagements. For daytime use, it is generally recommended to change the pad every 2–3 hours to maintain vulvar hygiene during menstruation. If heavy menstrual bleeding occurs and the pad becomes saturated shortly after use, immediate replacement is necessary to prevent clothing contamination. Additionally, menstrual blood serves as an ideal bacterial culture medium; prolonged pad retention may lead to bacterial proliferation, compromising vulvar hygiene. For nighttime use, nightwear-style sanitary pads or women's hygiene pants can be selected for continuous application. However, if excessive bleeding causes pad saturation, prompt replacement remains essential.
