Period care has evolved. Many people now prefer products that feel gentle on the body, safer for the skin and kinder to the planet. A period panty fits into that shift. You wear it like regular underwear, and it absorbs your flow without crinkly plastic backing or sticky adhesives that inevitably stick to you.
Yet it brings new questions. How often should you change it? Can you sleep in it? How long can you keep period underwear on without irritation? These are practical concerns, and knowing everything about period panties can help make the experience better. Let’s dive into a few common queries to ensure you pick the right period panty for you, plan your day, and trust your body rather than second-guess it.
How Does Period Underwear Actually Work?
Period care becomes trustworthy when you know its details - how it works, it’s components etc. Mahina’s reusable period underwear is engineered with a three-layer gusset that stays thin, breathable and reliably protective across real flow patterns:
- Top layer: A soft, breathable surface that wicks moisture away quickly, keeping your skin dry through long hours or overnight wear.
- Middle layer: The absorbent core that draws fluid in and holds it securely, so nothing sits on the surface or feels damp.
- Bottom layer: A breathable, leak-proof TPU barrier that prevents spotting or stains.
With the basics in place, it becomes easier to understand how often to change your reusable period underwear during a full day.
How Often Should You Change Your Period Panty?
How long you can keep period underwear on depends on two things: your flow and the absorbency level you choose. Mahina’s period panty is designed for up to 12 hours of wear. The idea is not to change frequently; it is to opt for a pair that is designed to match your flow. If your flow tends to surge at specific times, such as early morning or late evening, choose Mahina’s period panty in the absorbency level that aligns with that pattern. Here’s a breakdown of our three absorbency levels built to tackle every phase of your cycle:
- Medium Absorbency: Holds up to 25 ml. Great for regular flow. If you change 3 pads in 12 hours, or fill up 1 menstrual cup in that time, this is for you.
- Heavy Absorbency: Holds up to 40 ml. Built for heavier days. If you go through 4 pads or 2 menstrual cups in 12 hours, go for this.
- Super Heavy Absorbency: Holds up to 50 ml. Maximum protection. If you use over 5 pads or 2.5 menstrual cups in 12 hours, opt for this absorbency level.
One of Mahina’s period panties gives you up to 12 hours of wear. Since most menstruators will want to change a minimum of twice a day, morning and night, you’ll need around 5 to 7 pairs if your period lasts 5 days. This rotation covers your cycle comfortably, so you don't have to stress about laundry. But if you’re able to wash, dry, and rotate your pairs every day or every other day, you can easily manage with 3 to 4 pairs. Once you establish a pattern, your set of reusable period panties becomes predictable and easy to rotate.
“But is it hygienic to wear a period panty for 12 hours?”
Yes! You can also feel completely assured about hygiene, because Mahina’s period underwear is tested at every step of the way. Every skin-touching layer is checked in NABL-accredited labs to meet strict EU and US safety standards, ensuring there are no harmful chemicals or restricted substances. It’s even tested for safety after months of real-world use. The results show microbial levels stay well below the 1000 cfu/gm benchmark, showing minimal bacterial or yeast growth. With the right wash care, each pair stays hygienic, gentle, and safe to wear through every phase of your cycle.
The Right Way To Wash Period Underwear
Caring for Mahina period underwear is simpler than most people expect. Here are a few steps to ensure your period panties stay clean and hygienic throughout their lifespan:
- Rinse soon after use: Use cool water and gently press the gusset until the water runs clear.
- Optional short soak: Ten to twenty minutes in cool water helps loosen any remaining blood. You can do this before or after the rinse.
- Wash gently: Hand wash with mild detergent or machine wash on a gentle cycle. Avoid bleach and softeners.
- Air dry fully: Clip at the waistband and let it dry completely. Do not wring, tumble dry or iron.
- Avoid common mistakes: No hot water, no wringing, no harsh chemicals and no storing before the panty is completely dry.
This routine keeps each reusable period panty effective through 100 washes and maintains hygiene without any special effort.
