Period underwear is a reusable, comfortable, and environmentally friendly option for managing menstrual flow, and its uptake is rapidly increasing amongst today’s conscious and savvy consumers. Washing and maintenance require some getting used to initially. Still, once it becomes a routine, most people can manage without much hassle.

What to look for when buying period underwear?

Smita B Kalappa, an Obstetrician and Gynaecologist at Apollo Clinic, Bengaluru, shares key factors to choose the right period underwear.

1. Material

Period underwear is usually made of breathable fabrics like cotton or bamboo and features multiple layers with technology that locks fluid away from the skin, helping maintain dryness. They also have antimicrobial properties that prevent odour buildup and microbial growth. Women of all ages can use them without causing the skin irritation and rashes associated with sanitary napkins.

2. Size and absorbency

Period underwear comes in different sizes and absorbency levels. So, consumers need to buy 3-5 pairs to use on heavy-, medium-, or light-flow days, respectively. It can take a bit of trial and error to find the most comfortable fit.

3. Cost

The average cost of period underwear ranges from 200 to 900 per pair, depending on the brand and features. While the initial investment may seem high, these products can often be reused for up to 2 years with proper care. Buying 3-5 pairs can help manage different flow days, making it a cost-effective option in the long run compared to traditional disposable menstrual products.

4. Duration of use

One pair of period underwear can be safely used for 8-12 hours at a time, depending on your individual flow. This makes them an excellent choice for busy individuals such as students or working women, as well as for travel when bathroom breaks may be less frequent. However, it's essential to consider your individual flow levels. For lighter days, 12 hours may be perfectly comfortable. Still, on heavier flow days, you might want to plan for shorter durations and change more frequently to maintain comfort and prevent leakage. Additionally, these panties offer peace of mind during long periods away from home, providing reliable protection without the need for additional products.

5. Usage

They can be used for post-delivery bleeding and also in women who experience urinary leakage. As for washing and maintenance, it's vital to rinse the panties in cold water until the blood drains out. After that, you can either hand-wash them with a mild detergent or machine-wash them without fabric conditioner. Air-drying is recommended to preserve the fabric's integrity and ensure its longevity. Once you get used to this routine, caring for your period underwear becomes a quick and manageable task.

How long should you wear period underwear for?

When buying period underwear, it's important to consider how long you'll use it during your menstrual cycle. This affects both comfort and performance. Here are a few key reasons why:

  1. People have different levels of flow during their period. It's important to know how long period underwear can be worn, which is usually 8 to 12 hours. This helps you pick the right underwear for heavy, medium, or light days.
  2. If you have a busy schedule, like being at work or school for long periods, it’s important to choose underwear that can handle extended wear without leaking. This way, you can go through your day without worrying about leaks.
  3. Knowing how long you can use something helps you plan better. For example, if you know a pair lasts 10 hours, you can wear them on outings or during travel without worrying about frequent bathroom breaks.
  4. Wearing period underwear for the right amount of time based on your flow level will keep you comfortable and help prevent leaks or irritation. These issues can occur if you wear the underwear for too long on heavy-flow days.

Brands offering period underwear in India

The Indian market has many brands, both local and global, offering leak-proof period underwear in different absorbency levels. Popular choices include Pee Safe, which offers reusable underwear for light- to heavy-flow; Mahina by Nua, known for its cotton-rich, rash-free designs; and Azah, which offers high-absorbency styles tested to last up to 12 hours. Other well-known brands include Soqoh, which focuses on size-inclusive fits. HealthFab GoPadFree, which offers lab-certified reusable underwear, and Sironona, which uses FDA-approved antibacterial fabric.

Myths about period underwear

Period underwear is becoming more popular, but they also come with many myths and misunderstandings. The doctor separates myths from facts.

  • Period underwear is hygienic and easy to clean: It is clean as soon as it is washed and dried, and has a lower risk of infection. Dangerous conditions like toxic shock syndrome with tampon use are completely avoided.
  • Period underwear is bulky: It's just like regular underwear and comes in multiple sizes and designs.
  • Period underwear causes leakage and is only for light-flow days. As per the expert, period underwear provides good coverage and can absorb up to 50 mL of menstrual fluid at a time. They may be combined with tampons or menstrual cups during the initial adjustment period.
