Why Use Non Toxic Period Underwear?

Non-toxic period underwear is an excellent choice for anyone looking for an eco-friendly, cost-effective, chemical-free, and convenient alternative to traditional disposable menstrual products. Plus, they are so comfortable with the coverage of any regular undie and are easy to clean up. And if you need more motivation to make the sustainable switch, then take these:

  • Protects Your Health: Traditional period products such as pads and tampons contain chemicals like PFAS, which can disrupt your hormonal balance and irritate your intimate area, potentially leading to long-term health complications. However, these risks can be eliminated through PFAS-free organic non-toxic period underwear that ensures you are not exposed to hazardous chemicals.
  • Better for the Environment: Disposable period products generate an enormous amount of waste that can take hundreds of years to decompose, resulting in a disastrous impact on the planet. On the other hand, eco-friendly period underwear can be reused multiple times, significantly reducing waste generation and plastic pollution.
  • Saves You Money: Single-use period products might feel affordable in the first go, but they are actually expensive if you add up the cost over time. Investing in high-quality, PFAS-free period underwear can save you money in the long run, as they are designed to last for years, eliminating the need for frequent menstrual care purchases.
  • Comfortable and Convenient: Non-toxic period underwear is designed to be both comfortable and convenient. They are available in a range of styles and absorbency levels to suit your specific needs. Plus, the soft, breathable and green materials used in their fabrication guarantee a snug feeling while you’re ‘Aunt Flo’ is visiting.
  • Supports Ethical and Sustainable Manufacturing: Choosing to purchase organic and non-toxic period underwear supports ethical and sustainable manufacturing practices. Many brands that produce these products prioritize fair labor standards and environmentally responsible manufacturing, verifying that your purchase has a positive impact beyond your personal use.

Commonly Found Chemicals in Traditional Period Products and Their Harmful Effects

  • PFAS: PFAS or per- and polyfluoroalkyl substances are chemicals often used to produce disposable menstrual products such as pads and tampons. Consisting of a large group of synthetics, PFAS was introduced to the industry somewhere in the 1940s. Since then, it has been widely used in consumer goods items because they make products waterproof. Also known as  “forever chemicals,” PFAS have been linked to hormonal disruption, menstrual irregularities, ovarian disorders, immune system dysfunction, low birth weight in babies (in-utero), and increased cancer risk.
  • Dioxins: Dioxins form when white pads (or tampons) are born. These chemicals are a by-product of the bleaching process of conventional menstrual products. They are known to be highly toxic and have been connected to cancer and reproductive health problems like endometriosis. However, the exposure to dioxins via tampons and diapers is less than diet and other emissions. 
  • Fragrances and Dyes: Fragrances and dyes are a regular part of single-use period products. But they can irritate sensitive areas of your body and may even cause allergic reactions. Phthalates are often used as fragrance fixatives or liner adhesives in menstrual pads. They can enter the body via the dermal (vulvar or vaginal) route and are well known for their ability to disrupt the endocrine system and inder neurological development. These chemicals also harm the environment, massively contributing to water pollution.
  • Chlorine: Chlorine is often used to produce traditional menstrual products, mainly bleach materials like cotton and wood pulp. This, again, is a chemical that is harmful to both the environment and human health.
  • Volatile Oxygen Compounds (VOCs): If you know benzene, you know VOCs. These are carbon-containing compounds that evaporate quickly. Hygiene products like wipes, washes, sprays, menstrual pads, and tampons have VOCs in varying amounts. Like phthalates, these chemicals are detected in fragrances, adhesives, moisture barriers, and absorbents. Some studies have correlated prolonged exposure to VOCs with respiratory problems and neurological disorders. In worst-case scenarios, they can even cause damage to the reproductive system and cancer.

Final Thoughts…

Switching to non toxic period underwear is a powerful step towards achieving a healthier and more sustainable menstrual cycle. By choosing organic and eco-friendly materials, you can avoid exposing your privates to fatal chemicals while also reducing your environmental impact. A win-win for all! So embrace your flow in the most mindful way, because menstruating women deserve nothing but the best. I promise, once you experience the comforts and convenience of organic non toxic period underwear, there’s no going back. Happy Periods!
