Understanding the Causes of Odor in Period Underwear

Natural Menstrual Odor

It’s important to recognize that a slight odor during menstruation is normal. Menstrual blood contains a mix of blood, vaginal fluid, and tissue, which can produce a natural scent. According to Healthline, this combination is typically not a cause for concern unless there are significant changes in smell or consistency.

Bacterial Growth

Odor can become intense due to bacterial growth in the underwear. When menstrual blood remains in contact with fabric for extended periods, bacteria can thrive, leading to unpleasant smells. Proper hygiene practices are essential to prevent this.

Material Composition

The type of material used in period underwear can also influence odor retention. Synthetic fabrics may trap moisture and odors more than natural fibers. Brands like Saalt and Cheeky Wipes emphasize using breathable materials to combat this issue.

Tips for Preventing Odor

1. Choose the Right Product

Selecting the right period underwear based on your flow and activity level is crucial. For heavy flow days, opt for products with higher absorbency and odor control features, such as those from SuperBottoms or Hello Period.

2. Maintain Good Hygiene

Regular changing of period underwear is vital. Depending on your flow, aim to change every 4-8 hours. This practice helps minimize bacteria growth and odor.

3. Wash Properly

Follow the manufacturer’s washing instructions. Most period underwear should be washed in cold water to prevent damage and odor retention. Avoid fabric softeners, as they can leave residue that affects absorbency.

4. Air Dry

Air drying is recommended as it helps maintain the integrity of the fabric and prevents the growth of bacteria. Avoid using a dryer, as heat can damage absorbent materials.

5. Use Antimicrobial Products

Consider period underwear that features antimicrobial properties. Brands like Lumedeodorant offer products designed to combat odor effectively.
