Can I Wear Period Underwear for 24 Hours?

Wearing period underwear for 24 hours straight is generally NOT recommended, mainly for hygiene and comfort reasons:

  • Absorbency Limits: Most period underwear is designed to hold a few tampons’ worth of flow (usually 2-3 regular tampons). After full absorption, the fabric stays wet, which can cause discomfort and leakage.

  • Hygiene: Wearing them too long increases the risk of bacterial growth and odor, which might lead to infections or irritation.

  • Flow Depends: If you have a very light flow or are wearing multiple layers of period protection (e.g., period panties + tampon/pad), it might be okay for extended wear, but usually changing every 8-12 hours is safer.

Best Practice: Change period underwear every 8-12 hours to keep fresh, dry, and healthy.

How to Wash M&S Period Pants (Marks & Spencer Period Underwear)

M&S period pants are made with special absorbent fabrics that require gentle care. Here’s how to wash them to keep them effective and long-lasting:

Washing Instructions:

  1. Rinse Immediately: Rinse your pants in cold water right after use to prevent stains from setting.

  2. Machine Wash:

    • Turn pants inside out.

    • Use a gentle or delicate cycle.

    • Wash at 30 degrees Celsius (cold water).

    • Use a mild detergent without bleach or fabric softener.

  3. Avoid Bleach & Fabric Softeners: These damage the waterproof and absorbent layers.

  4. Do Not Iron or Dry Clean.

  5. Dry Naturally: Air dry flat or hang to dry in shade; avoid tumble drying or direct sunlight to prevent fabric damage.

Extra Tips:

  • For stubborn stains, soak in cold water with a mild detergent or oxygen-based stain remover before washing.

  • Avoid hot water to preserve the integrity of the waterproof layer.
