Period Panties: Safe, Hygienic, Or Overhyped? Here's What The Expert Says (2025)

When we talk about menstrual products, there are sanitary pads, tampons, menstrual cups, and now, a relatively new product on the market: period panties. The latter two options are more eco-friendly and sustainable, especially considering that in India, more than 12 billion pads and panty liners are sent to landfills every year. Most of these products have a plastic lining that takes 400-500 years to decompose.

But are they truly safe and hygienic or just another overhyped product? We spoke to Dr Shelly Singh, Director, Obstetrics and Gynaecology, Fortis La Femme, GK II, New Delhi, who shared insights on period panties, their uses, benefits, and risk factors.

What Are Period Panties?

Period panties are absorbent products with multiple layers that absorb and wick away moisture, menstrual blood, sweat, vaginal discharge, and minor urine leaks. According to the New Jersey Department of Health, period underwear can be used for sports, swimming, and overnight protection. They can replace both internal and external products like pads or tampons.

Period panties are designed to be worn like regular panties and come in various sizes. “To prevent leakage, it's essential to choose the right fit; if they're too loose, blood may leak out, while a too-tight fit will be uncomfortable. The outermost layers are typically made from cotton, spandex, and bamboo,” said Dr Singh.

How Do Period Panties Work?

Period panties are designed to accommodate different types of flow. "For the initial few days of heavy flow, they have additional absorbent layers and lining, while for times of medium and minimal flow, they have fewer layers. Some types also feature an antimicrobial layer to prevent bacterial buildup and minimise odours. However, some period panties may not be able to eliminate the smell of menstrual blood," explained Dr Singh.

Period panties come in disposable and reusable options. Reusable ones can be used for six months to two years, whereas disposable ones must be discarded daily. Additionally, period panties can serve as a backup for tampons and menstrual cups on days when dealing with heavy flow.

Period Panties Vs Other Menstrual Products

Compared to sanitary pads, period panties are easier to use and may feel less bulky. "Some girls, especially teenagers, may find it difficult to use menstrual cups or may not feel comfortable with them. For these girls, period panties are a convenient alternative. Tampons, on the other hand, absorb blood internally, but they carry inherent risks of infection, including Toxic Shock Syndrome," said Dr Singh

Are Period Panties Hygienic?

If used correctly, the answer is yes, they can be sanitary. Follow these expert-recommended steps to ensure hygiene:

• Change them every 4-8 hours on days of heavy flow and at least once every 12 hours on days of light flow.
• Wash them properly, either by hand or in the washing machine, preferably separate from other clothes.
• Use a mild detergent and avoid fabric softeners.
• Air dry them and ensure no residue of soap or washing powder remains after a wash.

Are There Any Health Risks Of Period Panties?

"Some period panties contain PFAS (Per- and Polyfluoroalkyl Substances), also known as "forever chemicals." These substances are commonly used in furniture, cookware, and other products to make them resistant to oil, heat, water, and stains," explained Dr Singh. However, cumulative exposure to PFAS has been linked to various health concerns, including high cholesterol, elevated liver enzymes, and certain types of cancer. To minimise potential risks, choose period panties that are labelled as PFAS-free.

Bottomline

Dr Singh concluded, "Period panties are a viable option that can be used effectively. When used properly, they offer a sanitary, hygienic, and more environmentally friendly solution to help manage your menstrual flow."
