The PFAS Problem in Period Underwear

The PFAS Problem in Period Underwear: How to Protect Your Health with Femi.Eko®

We know why you chose period underwear: you wanted to avoid the plastic in traditional pads, save money, and do something good for the planet. But what happens when you find out that even “sustainable” alternatives may hide invisible risks?

A recent 2025 study has raised a global alarm: many popular brands of period underwear contain PFAS, also known as “forever chemicals.” At Femi.Eko®, we believe your protection should never be a compromise between comfort and chemical safety.

What are PFAS and why should you care?
PFAS (per- and polyfluoroalkyl substances) are a group of over 4,000 synthetic chemicals used to make materials resistant to water and stains. While this may sound useful in menstrual products, the potential cost to your health is significant.

Why are they concerning in intimate areas?
The skin in the intimate area is thinner and more permeable than other parts of the body, which may allow chemicals to be absorbed more easily. PFAS exposure has been associated with:

Hormonal disruption and endocrine effects
Chronic irritation and inflammation of sensitive skin
Fertility concerns and potential immune system effects

The “Cheap Waterproofing” Trap
Many brands use PFAS because it is a low-cost solution for leak protection. Some also add silver chloride as an antibacterial agent. While this may sound beneficial, it can disrupt the natural vaginal microbiome and lead to irritation or imbalance.

Femi.Eko® Tip: Don’t rely on “eco” claims alone. Always check whether the brand provides clear certifications and transparency about the absence of harmful chemicals.

The Femi.Eko® Solution: Innovation Without Compromise

At Femi.Eko®, we chose the more responsible path: investing in safer, natural materials.

1. Patent-Pending Blend: Hemp + Organic Cotton
At the core of our products is an innovative absorbent layer.

Why hemp?
Naturally antibacterial, without the need for silver or biocides
Higher absorbency than standard cotton
Breathable, helping reduce irritation and odor

2. Safe Waterproofing (PFAS-Free)
To prevent leaks, we use technical protective layers (PU) applied mechanically, not chemically treated with PFAS. This ensures effective protection while maintaining product safety.

3. OEKO-TEX® Standard 100 Certification
You don’t have to take our word for it. Our products are certified according to OEKO-TEX® Standard 100, meaning they are tested against harmful substances and meet strict safety criteria.

Why Choose Femi.Eko® Today?

Natural comfort: no “plastic” feeling, only skin-friendly materials
True sustainability: responsibly sourced materials designed for long-term use
Certified safety: transparency and quality at every level

The PFAS issue is real, but the solution is simple. By choosing clean, certified products, you invest in your long-term health and a better future. Switch to protection without compromise.

FAQ

How can I tell if my current period underwear contains PFAS?
If the brand does not clearly state certifications like OEKO-TEX® or “PFAS-free,” and relies on undocumented synthetic “stay-dry” technologies, there may be a risk.

Are natural materials as effective?
Yes. The combination of hemp and organic cotton in Femi.Eko® products is designed to handle even heavier flows with efficient absorption.

Hvordan svømmer man under menstruation uden tampon: Den ultimative guide

Hvordan svømmer man under menstruation uden tampon: Den ultimative guide

Hvordan svømmer man under menstruation uden tampon: Den ultimative guide For mange kvinder og teenagere betyder det ofte automatisk, at de undgår poolen eller stranden, når menstruationen kommer. Stressen, angsten og ubehaget ved at bære tampon eller et traditionelt bind under aktiviteter i vand er reel og almindelig. Hvis du nogensinde har spurgt dig selv, hvordan man svømmer under menstruation uden tampon, eller om der findes en moderne og sikker løsning, som gør det muligt for dig at nyde vandet uden bekymringer, så er denne guide til dig. Sammen ser vi nærmere på, hvordan Femi.Eko® menstruationsbadetøj fungerer, hvad der gør det anderledes, og hvordan det helt kan forandre din oplevelse på menstruationsdage. Følelsen på varme dage og frygten for menstruation Forestil dig dette: en perfekt sommerdag, en poolfest eller en ferie ved havet, og så kommer menstruationen præcis på det tidspunkt. Følelsen af frustration og uro kan være overvældende. Du svømmer i skolen, vil gerne have det sjovt med vennerne og slappe af i vandet, men du er bange for lækage, ubehag eller for at skulle bruge en tampon, som ikke altid er behagelig eller særligt skånsom mod din hud. For teenagere kan denne situation blive en kilde til stressende dage, især under idræt eller svømmeundervisning. Spørgsmålene og følelserne er mange: “Kan jeg gå i vandet uden at bekymre mig?”, “Hvad nu hvis tamponen ikke holder?”, “Er det hygiejnisk at være i vandet med et bind?”, “Hvordan kan jeg føle mig komfortabel og beskyttet?” Disse bekymringer er naturlige og helt forståelige. Heldigvis har teknologien udviklet sig, og brands som Femi.Eko® har skabt innovative løsninger, der imødekommer netop disse behov. Hvorfor vælge at svømme under menstruation uden tampon? Lad os først se på, hvorfor det kan være et rigtig godt valg at svømme under menstruation uden tampon: • Mere komfort: En tampon kan give ubehag eller en følelse af udtørring i skeden, især hvis du er i vandet i længere tid. • Sikkerhed: Der er en risiko for toksisk shock syndrom (TSS) forbundet med brug af tamponer, især hvis de bæres for længe. • Frihed: Du behøver ikke være afhængig af at skifte tampon hver få timer, især når du ikke nemt har adgang til et toilet. • Bæredygtighed: Genanvendelige eller innovative løsninger reducerer affaldet fra klassiske bind og tamponer. • Hygiejne: Menstruationsbadetøj er særligt udviklet til at sikre en frisk og ren følelse, også i vand. Hvordan fungerer Femi.Eko® menstruationsbadetøj? Femi.Eko® menstruationsbadetøj er en europæisk innovation, som kombinerer avanceret teknologi med moderne design for at gøre svømning under menstruation til en sikker, behagelig og bekymringsfri oplevelse. Lad os se nærmere på, hvordan det fungerer. Det absorberende inderlag Den vigtigste del af badetøjet er det indvendige lag, som er lavet af superabsorberende, OEKO-TEX-certificerede materialer, der kan holde på betydelige mængder menstruationsvæske. Denne teknologi gør det muligt hurtigt at absorbere menstruationsblodet, så der ikke er risiko for lækage eller synlige pletter udenpå. De anvendte materialer er bløde mod huden, åndbare og giver ikke en ubehagelig følelse af fugt mod huden. Derudover er de behandlet antimikrobielt for at modvirke udvikling af bakterier og uønsket lugt, så du får optimal hygiejne hele dagen. Vandafvisende yderlag (DWR) For at forhindre vand fra poolen eller havet i at trænge ind i det absorberende lag er badetøjet udstyret med et vandafvisende yderlag med DWR-behandling (Durable Water Repellent). Dette lag afviser vand, så menstruationsblodet absorberes, mens vandet fra poolen eller havet ikke trænger ind. Det betyder, at du ikke vil opleve en våd eller tung fornemmelse, som skyldes opsuget vand, og badetøjet vil ikke svulme op eller blive ubehageligt, sådan som nogle kvinder frygter. Yderlaget beskytter samtidig det absorberende materiale og forlænger badetøjets levetid. Ergonomisk design og materialer i premiumkvalitet Badetøjets design er ikke kun udviklet med fokus på funktion, men også på komfort og stil. Den moderne pasform former sig efter kroppen og giver bevægelsesfrihed samt støtte, hvor det er nødvendigt. Materialerne i premiumkvalitet føles behagelige mod huden, og vedligeholdelsen er nem, da det kan vaskes i maskine uden risiko for at beskadige materialerne. Myter og almindelige bekymringer om menstruationsbadetøj 1. “Badetøjet vil svulme op som en ble i vandet” Dette er en af de mest almindelige bekymringer. Det er vigtigt at vide, at det absorberende lag kun holder på menstruationsblodet, ikke vandet fra poolen eller havet. Takket være det vandafvisende yderlag trænger vandet ikke ind, og derfor vil badetøjet ikke svulme op eller blive ubehageligt i vandet. 2. “Er det hygiejnisk at være i vandet med menstruationsblod?” Ja. Femi.Eko® badetøj er udviklet specifikt til at håndtere menstruationsvæske på en hygiejnisk måde. De antimikrobielle og absorberende materialer holder området tørt og beskyttet og hjælper med at forhindre bakterievækst. Derudover fortyndes menstruationsblod straks i vand og skaber ikke hygiejniske problemer. 3. “Kan jeg kun bruge badetøjet på dage med let flow?” Ikke nødvendigvis. Femi.Eko® menstruationsbadetøj kan også bruges på dage med moderat eller endda kraftig menstruation, afhængigt af den valgte model og hvor ofte du ønsker at skifte eller skylle badetøjet. Menstruationsbadetøj til teenagere: en stor forandring For teenagere er menstruationsbadetøj en ægte game changer. Mange unge undgår svømmeundervisning på menstruationsdage på grund af flovhed eller frygt for lækage. Med Femi.Eko® kan de deltage i svømmetimer uden stress og uden at skulle bruge tamponer eller bind, som kan være ubehagelige eller endda forbudt på nogle skoler. Badetøjet giver fuld tryghed og komfort, så de kan fokusere på det, der virkelig betyder noget: at have det sjovt og lære. Fordele ved at bruge Femi.Eko® menstruationsbadetøj • Komfort og frihed: Uden følelsen af udtørring eller irritation kan du svømme og bevæge dig frit. • Sikker beskyttelse: Den effektive absorption forebygger lækage og holder huden tør. • Garanteret hygiejne: De antimikrobielle materialer og den særlige behandling holder miljøet rent. • Bæredygtighed: Produktet kan genbruges og reducerer affaldet fra engangsbind. • Fuld diskretion: Det moderne design og den gennemtænkte pasform efterlader ingen mærker og føles ikke som et traditionelt menstruationsprodukt. • Holdbarhed: Materialer i europæisk kvalitet sikrer langvarig brug. Ofte stillede spørgsmål (FAQ) Kan jeg gå i poolen med menstruationsbadetøj på dage med kraftig menstruation? Ja, Femi.Eko® menstruationsbadetøj er udviklet til også at kunne håndtere kraftig menstruation. Takket være det absorberende inderlag og det vandafvisende yderlag holdes blodet effektivt inde, mens vandet fra poolen ikke trænger ind i badetøjet. Ved meget kraftig menstruation anbefales det dog at have et ekstra badetøj med til omklædning, især hvis du skal være i vandet i flere timer. Hvordan vedligeholder man Femi.Eko® menstruationsbadetøj? Badetøjet kan nemt vaskes i hånden eller i vaskemaskine på et skåneprogram med et mildt vaskemiddel uden blegemiddel. Det anbefales at undgå direkte sollys ved tørring og ikke bruge tørretumbler, så materialernes egenskaber bevares bedst muligt. Hvor ofte skal badetøjet skiftes i løbet af dagen? Det afhænger af menstruationens styrke og af modellen. Ved moderat flow kan det typisk bruges i flere timer. Ved kraftigere menstruation kan det være nødvendigt at skifte det efter nogle timer for maksimal komfort. Er badetøjet også egnet til andre sportsaktiviteter? Ja, takket være det ergonomiske design og de elastiske og åndbare materialer er badetøjet også velegnet til andre sportsaktiviteter, ikke kun svømning. At svømme under menstruation uden tampon er ikke længere en drøm, men en reel mulighed takket være teknologien bag Femi.Eko® menstruationsbadetøj. Dette revolutionerende produkt giver dig friheden til at nyde vandet uden ubehag, frygt for lækage eller bekymringer om hygiejne. Uanset om du er teenager, studerende eller en aktiv kvinde, er Femi.Eko® badetøj en pålidelig støtte på de mere krævende dage. Begræns ikke længere dine aktiviteter under menstruation. Udforsk Swimwear-kollektionen fra Femi.Eko® og vælg den model, der passer bedst til dig. Nyd denne sommer i poolen eller ved havet med selvtillid og komfort.

The Morning-After Pill: Your Guide to Emergency Contraception and Safety

The Morning-After Pill: Your Guide to Emergency Contraception and Safety Life doesn't always go as planned. A condom might break, a birth control pill might be forgotten, or contraception might be overlooked in the moment. In such situations, the morning-after pill (emergency contraception) serves as an important safety net. There are many myths about morning-after pills – from fears of infertility to misunderstandings that it's a form of abortion. Here you'll find the cold facts and practical guidance on how to best care for your body when an accident happens. What is a morning-after pill and how does it work? A morning-after pill is a hormonal treatment designed to prevent pregnancy after unprotected intercourse. It's important to understand that the pill is not an abortion pill; it cannot terminate a pregnancy that has already occurred. How it works: The pill primarily works by delaying your ovulation. Since sperm can survive up to five days inside a woman's body, emergency contraception aims to "shift" ovulation so that the sperm die before the egg is even released. If ovulation has already occurred, the pill usually has no effect. Morning-after pill: When should it be taken? Time is the most crucial factor when it comes to emergency contraception. The sooner you take the pill, the higher its effectiveness. In Denmark, there are generally two types: Levonorgestrel (e.g., Plan B): Should preferably be taken within 24 hours, but is effective for up to 72 hours (3 days). Ulipristal acetate (e.g., ellaOne): Is more effective and can be taken up to 120 hours (5 days) after intercourse. Even if you have 3-5 days, you should always visit a pharmacy as soon as possible. Remember that the morning-after pill is a backup solution and should not replace regular contraception, as it is less reliable than, for example, birth control pills or IUDs. How many times can you take a morning-after pill? There is no fixed medical limit to how many times in one's life emergency contraception can be taken, and it does not lead to infertility. However, it is not recommended to use it as a regular form of contraception for several reasons: Hormonal burden: It contains a high dose of hormones, which can cause side effects such as nausea and headaches. Cycle disturbances: Your next period may be delayed or irregular. Cost and safety: Regular contraception is both cheaper and much safer. Care for your body after emergency contraception After taking a morning-after pill, your body may feel a bit different for a period. You may experience spotting or tender breasts. At Femi.Eko, we know that these unexpected bleedings can cause uncertainty. Our  period underwear is ideal for the days after emergency contraception, as they provide discrete and comfortable protection against unexpected spotting while your cycle returns to its natural rhythm. It's also important to take a pregnancy test approximately 3 weeks after taking the pill to be absolutely sure that it worked as intended. Myths vs. Facts Myth: Morning-after pills cause sterility. Fact: No, fertility returns to normal immediately in the next cycle. Myth: It's the same as an abortion. Fact: No, the pill prevents fertilization. If the egg is implanted, the pill does no harm.

Through Femi.Eko, Narcisa works to remove shame around contraception and cycles, so that every woman can make informed choices for her own body.

Nymfomani: Myter, historie og moderne forståelse af libido

Nymphomania: Myths, History, and Modern Understanding of Libido

Nymphomania: Myths, History, and Modern Understanding of Libido Few words in sexuality are fraught with as many prejudices as "nymphomania". Throughout history, the term has been used for everything from a medical diagnosis to a social stigma placed on women's sexuality. Today, we no longer use the word in medical science, but it is still very much alive in everyday language – often with a misunderstood meaning. To understand nymphomania, we need to look at how society previously tried to control women's desires, and how today we instead talk about healthy libido and compulsive sexual behavior. What did nymphomania originally mean? The word comes from Greek and is composed of nymphē (young woman) and mania (passion or loss of control). In the 18th and 19th centuries, nymphomania was considered a serious illness. At that time, medical science was characterized by strict morality, and any woman who displayed a strong sexual desire or initiated sex was often diagnosed as "sick". Today, we know that these diagnoses were based on cultural prejudices rather than science. There is no single "normal" level of sexual desire, and the variation between people is enormous. Why don't doctors use the word anymore? Modern medicine and psychiatry (including the DSM-5 and ICD-11 manuals) have abandoned the concept of nymphomania for several reasons: It is gender-discriminatory: The word was only used for women. Men with high desire rarely received the same pathologizing label. Lack of objectivity: There is no method of measurement for when desire is "too much". Libido is affected by everything from hormones and stress to relationships. Focus on well-being: Today, the diagnosis Compulsive Sexual Behaviour Disorder is used instead. Here, the focus is not on how often one has sex, but on whether the behavior causes distress, destroys relationships, or is used as an escape mechanism from anxiety and stress. High Libido vs. Compulsive Behavior It is important to emphasize: A high sexual desire is not an illness. Some people naturally have a very high libido throughout their lives, while others experience periods of increased desire. This is a natural part of human diversity. The problem only arises if desire turns into compulsion. This can be recognized by: Losing control over one's impulses. Sex becoming a way to alleviate stress or sadness, rather than a source of pleasure. The behavior having negative consequences for one's work or private life. The Role of Hormones and Your Cycle At Femi.Eko, we know that women's desire is closely linked to their biology. Estrogen and testosterone play a key role in your libido, and many women experience a significant increase in desire around ovulation. It is completely natural to feel your body more intensely during certain periods. Owning your own desire and understanding your cycle is a strength – not an illness. Our mission is to create a sense of security around all aspects of the feminine body, so you can feel confident in your sexuality, no matter where your libido stands on the scale. When to Seek Help? If your sexual impulses feel like a burden, or if they affect your emotional well-being, it may be a good idea to talk to a sexologist or psychologist. The goal of professional help is never to suppress your desire, but to help you find a balance where sexuality is a positive part of your life.

Through knowledge and innovative products, Narcisa supports women in understanding their hormones, their desires, and their right to define their own health on their own terms.
