Understanding Period Underwear

Period underwear is designed to absorb menstrual flow while keeping the wearer dry and comfortable. According to Dr. Jessica Shim from CNN, these products come equipped with multiple layers of absorbent materials like cotton, nylon, or polyester, which help wick moisture away and combat odors. The eco-friendly nature of these products has contributed to their growing popularity, as highlighted by environmental studies noting that conventional menstrual products are often laden with plastic and can take hundreds of years to decompose.

How Often Should You Change Period Underwear?

The frequency of changing your period underwear primarily depends on your flow and the absorbency level of the underwear. Generally, here are some guidelines:

• Light Flow Days: You can wear light absorbency underwear for up to 12 hours, but it’s advisable to change them if they feel damp or uncomfortable.
• Moderate Flow Days: For moderate absorbency, change every 6-8 hours based on comfort and absorbency.
• Heavy Flow Days: Heavy absorbency underwear should be changed every 4-6 hours to ensure maximum protection and comfort.
• Overnight Use: Overnight underwear can typically be worn for up to 10-12 hours, but it’s best to choose a style specifically designed for overnight use for optimal protection.

Signs It’s Time to Replace Your Period Underwear

Period underwear can last anywhere from 6 to 12 months, depending on the level of care and the frequency of use. Here are some signs to look for that indicate it’s time to replace them:

• Worn Elasticity: If the fabric starts to lose its shape or elasticity, it’s time for a new pair.
• Reduced Absorbency: If you find that your period underwear isn’t absorbing as well as it used to, it may be time to replace them.
• Visible Wear and Tear: Look for holes, frays, or any other physical damages that could compromise their effectiveness.
• Persistent Odor: If odor persists even after washing, it’s a sign that the fabric may be breaking down.

Care Tips for Period Underwear

To maximize the lifespan of your period underwear, proper care is essential. Here are some recommended practices:

• Washing: Always machine wash your period underwear in cold water to preserve the fabric and absorbent layers. Avoid bleach and fabric softeners as they can degrade the materials.
• Drying: Air drying is recommended to maintain elasticity. If you must use a dryer, opt for a low heat setting.
• Storage: Store your underwear in a cool, dry place to prevent bacteria growth.
