Think Toxic Shock Syndrome is a thing of the past? Learn about the new risks associated with modern period products like cups and discs, and how to stay safe in 2025.
Protecting Your Flow: Toxic Shock Syndrome in 2025 and the New Risks of Modern Period Products
For many of us, the first time we heard about Toxic Shock Syndrome (TSS) was through a hushed, terrifying story from our mothers or a tiny, fine-print warning inside a box of super-absorbent tampons. We were taught that as long as we didn’t leave a tampon in for a whole day, we were “safe.”
Fast forward to 2025. The period aisle has been revolutionized. We have organic cotton tampons, medical-grade silicone cups, menstrual discs, and high-tech absorbent underwear. These products have given us freedom, saved us money, and helped us protect the planet.
But with these modern innovations comes a dangerous misconception: the idea that sustainable products are “TSS-free.”
Today, we need to have a heart-to-heart about the reality of TSS in the modern age. It is rare, yes, but it is still real. Understanding how the risks have shifted with 2025’s most popular products isn’t about fear—it’s about empowerment. It’s about knowing your body so well that you can enjoy your freedom without compromising your safety.
What Exactly is Toxic Shock Syndrome (TSS)?
Before we look at the new risks, let’s quickly refresh on what we’re dealing with. TSS is a rare but life-threatening complication caused by toxins produced by certain types of bacteria, most commonly Staphylococcus aureus (staph).
While staph bacteria live harmlessly on the skin or in the nose of many people, problems arise when they overgrow in the vaginal canal and release toxins into the bloodstream. This can trigger a massive inflammatory response, leading to a sudden drop in blood pressure and potential organ failure.
In the 1980s, the culprit was often high-absorbency synthetic tampons. Today, the culprits are more varied, and the risks often come down to how we handle our modern “reusables.”
The 2025 Risks: Why Modern Products Aren’t Risk-Free
The “Green Revolution” in period care brought a sense of security that isn’t entirely backed by science. Let’s break down the specific risks associated with today’s top products.
1. Menstrual Cups and the “Seal” Myth
Many women switched to menstrual cups under the impression that because they collect blood rather than absorb it, the risk of TSS is zero.
The Reality: Research, including a notable study published in Applied and Environmental Microbiology, found that the air introduced into the vagina when inserting a cup can actually encourage the growth of Staph aureus. Furthermore, if the cup is not cleaned meticulously, the bacteria can form a “biofilm” on the silicone surface that is very hard to wash away.
The Risk: Leaving a cup in for the “maximum” 12 hours (especially if it wasn’t boiled between cycles) can create a perfect, oxygen-rich breeding ground for bacteria.
2. Menstrual Discs and Deep Placement
Discs have become the “it” product of 2025 because they allow for mess-free period sex and can be worn for up to 12 hours.
The Risk: Because discs sit higher up in the vaginal vault, near the cervix, they can sometimes be more difficult to remove. Prolonged “fishing” for a disc with unwashed hands can introduce new bacteria into an environment that is already holding blood at body temperature—the ideal incubator.
3. Organic Tampons: The “Natural” Security Blanket
There is a common belief that “organic” means “safe from TSS.”
The Reality: The risk of Toxic Shock Syndrome is not necessarily about the chemicals in the cotton; it is about the absorbency and the duration of use. An organic tampon left in for 10 hours carries a similar risk to a conventional one. The bacteria don’t care if the cotton is pesticide-free; they only care about the oxygen and the stagnant blood.
4. Period Underwear and Moisture Retention
High-tech period underwear is a miracle for many, but 2025 has seen an increase in “heavy-duty” styles meant to be worn for 24 hours.
The Risk: While TSS is usually associated with internal products, prolonged contact with blood against the vulva can cause skin breakdown and irritation, potentially allowing bacteria to enter the body through micro-tears, especially if the underwear is not changed frequently enough or washed in high-heat cycles to kill bacteria.
The Symptom Checklist: Know the “Flu” That Isn’t a Flu
TSS moves fast. Because the symptoms often feel like a sudden case of the flu, many women dismiss them until they are in a crisis. If you are on your period (or have just finished it) and experience these, seek emergency care immediately:
A Sudden High Fever: A temperature of 102°F (38.9°C) or higher that comes on out of nowhere.
The “Sunburn” Rash: A flat, red rash that appears on your palms or the soles of your feet.
Low Blood Pressure: Feeling dizzy, lightheaded, or fainting when you stand up.
Vomiting or Diarrhea: Sudden and severe gastrointestinal upset.Muscle Aches: Intense, widespread body aches that feel much worse than typical period cramping.
Confusion: Feeling disoriented or “foggy” very quickly.
How to Stay Safe: 2025 Best Practices for Modern Period Care
We are not telling you to throw away your cup or your organic tampons! We are simply updating the “User Manual” for the modern age.
1. The “Golden Rule” of Reusables: Boil, Don’t Just Rinse
Rinsing your cup or disc with soap and water during your cycle is fine, but it is not enough between cycles. You must boil your silicone products in water for at least 5–10 minutes before your period starts and after it ends to break down any bacterial biofilm.
2. Shorten the Window
While many products advertise “12-hour protection,” experts increasingly recommend a 6-to-8-hour limit for internal products, especially if you have a history of infections or a sensitive microbiome. Giving your body a “break” (using a pad or period underwear overnight) can significantly lower the risk.
3. Hand Hygiene is Non-negotiable
In our busy lives, we often rush the insertion and removal process. However, your hands are the primary vehicle for Staph aureus. Scrub your hands like a surgeon before you go anywhere near your internal products.
4. Size Down Your Absorbency
If you are using tampons, always use the lowest absorbency necessary for your flow. If you can pull a tampon out after 4 hours and it is still partially dry, you are using an absorbency that is too high, which can cause micro-scratches in the vaginal wall and increase the risk of TSS.
5. Don’t “Prep” for Your Period
Never insert a cup or tampon in anticipation of your period starting. The vaginal environment needs its natural moisture and balance; inserting a dry product into a dry vagina causes irritation that makes it easier for toxins to enter the bloodstream.
The Emotional Mental Load of “Getting it Right”
As women, we already carry so much. We worry about leaking, we worry about the environment, we worry about our health. It can feel like just one more thing to have to be “perfect” at cleaning your menstrual cup or timing your tampons.
I want to remind you: Your safety is worth the extra five minutes. If you feel overwhelmed by the maintenance of a cup, it is okay to use pads. If you forget to boil your disc, it is okay to use a tampon for a day. Being “sustainable” should never come at the cost of your peace of mind or your physical safety.
A Message to Your Healthcare Provider
If you ever feel “off” during your period and you bring it up to a doctor, be specific. Tell them: “I am on my period, I use a menstrual cup (or tampons), and I am feeling these symptoms. I am concerned about Toxic Shock Syndrome.” In 2025, you are your own best advocate. Doctors are human, and they can miss things, but when you speak the language of your own symptoms, you help them help you.
Reclaiming Your Flow
The modern period is about choice. We have more options than ever before to manage our cycles with dignity and ease. By staying informed about the shifting risks of Toxic Shock Syndrome, you are ensuring that your period remains a powerful part of your life, rather than a dangerous one.
Keep flowing, keep choosing what works for you, and most importantly, keep listening to your body. It always knows the way.
