Why Choose to Make the Switch to Organic Period Underwear?

Have you ever wondered what disposable sanitary pads are made of? Menstruation may not be a frequently discussed topic, but everyone must know what they use during their period.

Pads are in close contact with your body, particularly the sensitive skin around your vaginal area, for around five days each month.

This skin is highly permeable, meaning substances that come into contact with it can be absorbed into your bloodstream and distributed throughout your body.

Unfortunately, disposable sanitary pads contain materials you wouldn't want near your vagina. These materials can cause unwanted side effects and negatively impact your health.

Some individuals experience heavier periods and intensified cramps, while long-term exposure may lead to severe illnesses like cancer.


Sanitary pads aren't naturally pure white. Their fibers undergo chlorine bleaching to achieve a clean and sterile appearance. This process generates dioxin, a highly toxic pollutant. Although dioxin levels in sanitary pads may seem low and harmless, they can accumulate in the body's fat stores over time and remain there for up to 20 years.

Exposure to dioxin has been linked to pelvic inflammatory disease, hormone dysfunction, endometriosis, and various forms of cancer.

Synthetic Materials

In addition to cotton, rayon (a synthetic fiber derived from wood pulp) is used in sanitary pads. While rayon is more affordable than cotton and enhances the pad's absorption capacity, it also contains dioxin from the bleaching process.


Conventionally grown cotton is heavily treated with pesticides and herbicides. These chemicals can linger on the cotton long after harvesting. Exposure to these chemicals may lead to infertility, hormonal disruption, thyroid malfunction, diabetes, endometriosis, and depression.


Many sanitary pads are advertised as 'leakproof' and feature an impermeable plastic layer at the bottom that prevents liquid or air from passing through. This plastic layer traps moisture and heat, creating an environment conducive to yeast and bacteria growth. It can also cause irritation, chafing, and soreness for sensitive individuals.


Scented sanitary pads with odor neutralizers and artificial fragrances contain undisclosed chemicals that can be absorbed into the bloodstream and cause side effects. Additionally, these fragrances can irritate the skin, leading to allergies and reactions.

My experience using organic period underwear

I used a menstrual cup for a while but needed a change. I wasn't keen on returning to disposable products or using cloth pads, mainly due to their appearance. Although I had heard of period underwear, I was skeptical about its functionality.

Despite my initial skepticism, I decided to try them and bought three pairs. Surprisingly, they worked exceptionally well, and I haven't used any other menstrual products since.

If you're considering making the switch to period underwear, here are a few things I learned in the beginning:

  1. The Importance of the Post-Wear Rinse

During my first experience with period underwear, I did not rinse them immediately after use due to an inconvenient situation. After a more intense pre-soak and a quick run through the washing machine, I saved the pad. I learned that rinsing them promptly after use is crucial for maintaining their absorbency and hygiene.

  1. Getting Comfortable with Your Fluids

Although I had used a menstrual cup before and was familiar with period blood, rinsing the underwear initially felt strange. However, over time, I became more comfortable hand-washing the underwear and rinsing them in the sink. It's just a part of the process!

  1. They're Just Regular Underwear

One of my main concerns was that period underwear would feel bulky or diaper-like. However, when they arrived, they looked and felt like regular underwear. I found them comfortable to wear with any outfit, and they didn't feel intrusive or restrictive.

The most surprising aspect of using period underwear was their convenience during my period. The thought of just putting on a pair of cute undies and carrying on with my day seemed too good to be true.

My initial cynicism was soon replaced with a genuine appreciation for this innovative and practical menstrual solution.

How many pairs do you need?

The number of pairs of period underwear you need depends on your flow, period length, and laundering habits. However, as a general guideline, consider the following factors:

  • Your flow: If you have a heavier flow, you may need to change your period underwear more frequently throughout the day, requiring more pairs. For lighter flows, you can wear one pair for an entire day.
  • Length of your period: The duration of your period will also impact how many pairs you need. If your period lasts for five days, you may need more pairs than someone whose period lasts for three days.
  • Laundry frequency: If you can wash your period underwear regularly, you may not need as many pairs. However, if you do laundry less frequently, you'll want to have more pairs on hand to last until your next laundry day.

On average, having 5-7 pairs of period underwear is a good starting point. This should cover a typical period length and provide you with options for daily wear.

If you plan to use period underwear exclusively during your period, you may want to have more pairs, especially if your flow is heavier or your period lasts longer. Ultimately, finding the right balance between having enough pairs for your needs and managing laundry frequency is essential.

Are they safe?

In the 2010s, Thinx made a splash by introducing reusable period underwear, capturing mainstream attention. A few years later, it was discovered that the highly absorbent material appeared to contain significant levels of PFAS (per- and polyfluoroalkyl substances).

A study found that some period underwear contains high levels of PFAS on its outer and inner absorbent layers. Also known as “forever chemicals,” PFAS are a group of long-lasting chemicals used to make products resistant to heat, oil, stains, and water.

You can often find them on furniture, plastic food covering, and nonstick cookware. They’re concerning because experts found that PFAS don’t break down easily in the environment. They can seep into your body and build up inside you.

Given the highly absorbent nature of the vulvar skin, choosing natural period underwear that ensures both comfort and safety from harmful substances is essential.

Today, the market offers a variety of natural and environmentally friendly alternatives that prioritize responsible sourcing, diverse sizing, and ethical manufacturing.

Before you buy period underwear, check with the maker or product labels to see if they mention “PFAS-free.” Avoid those that say “PFOA-free,” as this means it’s free of some PFAS chemicals, but not all.

Whether you use them as standalone protection or as additional leak support, explore our top picks for PFAS-free period underwear that will keep you feeling secure, comfortable, and eco-friendly throughout your cycle. Remember to research and select brands that avoid harmful chemicals and prioritize safe materials.

Can you wear period undies all day?

Period underwear can be worn all day, depending on your flow and absorbency level. Most period underwear brands suggest changing when you start feeling wet, indicating that the underwear has reached its maximum absorption capacity.

Remember that the absorbency you require may change as your period progresses. You might need maximum absorbency on the first day and lighter protection during the last few days.

Trying period underwear for the first time at home is a good idea, as it allows you to feel more comfortable, gauge your feelings, and switch back to your previous method if desired.

If you prefer extra protection, such as during heavy overnight bleeding, wearing a reusable pad with your period underwear is perfectly fine. Ultimately, the goal is to do what makes you comfortable and confident.

How to wash your panties?

To wash period underwear, follow these steps: 1) Rinse them in cold water immediately after use to remove excess blood, 2) Hand-wash or machine wash them on a gentle cycle using mild detergent, and 3) Hang them to dry.

How Do We Choose These Brands?

When evaluating organic period underwear brands, it's essential to consider the following factors to make an informed choice:

  1. Fabric composition and certifications:

Ensure the fabric used in the products is environmentally friendly, such as recycled materials, natural fibers, or certified organic textiles. Look for certifications like OEKO-TEX, GOTS, OCS, and Fair Trade, and materials such as TENCEL™ Lyocell, hemp, organic cotton, wool, or linen.

These sustainable certifications and materials help you avoid greenwashing and ensure that the products are organic or sustainable.

  1. Ethical sourcing and labor practices:

Investigate the brand's sourcing and manufacturing processes, including where the fabrics come from and the working conditions of the people involved. Prioritize brands that pay fair wages and maintain safe working environments, adhering to labor and human rights laws.

  1. Corporate responsibility and sustainability initiatives:

Consider the company's commitment to environmental and social responsibility. Brands dedicated to making a positive impact often give back to their communities, support local economies, and take steps to minimize their environmental footprint.

Look for initiatives such as carbon offset programs, biodegradable or recyclable packaging, and programs to reuse or repurpose pre-loved products.

A final word on Organic Period Panties

Switching to organic period underwear brands can significantly impact your health, the environment, and the communities involved in the production process.

By choosing products made from eco-friendly, certified materials and supporting brands with ethical sourcing and corporate responsibility, you contribute to a more sustainable and equitable future.
