In fact, an article in National Geographic highlights that, although it’s difficult to specify how much plastic waste comes from menstrual products, in 2018 alone, 5.8 billion tampons were purchased in the United States. All ended up in landfills as plastic waste.

The importance of hygiene in a menstrual cup

Overal, the menstrual cup provides some great benefits:

  • It’s a discreet element,
  • It’s budget-friendly,
  • It is an environmentally sustainable method.

In fact, the Chilean Journal of Obstetrics and Gynecology defines it this way. These containers are designed with flexible material, such as silicone or medical rubber and hypoallergenic.

Although they don’t pose a risk of infection, as can happen with other intimate sanitary items linked to menstrual toxic shock syndrome (MTS), sterilizing and cleaning the cup is essential if you want it to be safe.

Research published in The Lancet supports the effectiveness of the product for controlling the flow of menstruation and reports a decrease in candidiasis in those who use it. However, some adverse reactions may be linked to improper use of the device or irregularities in cleaning it.

Sterilization of the menstrual cup

Sterilize the cup before inserting it for the first time in your body. Also do this after each menstrual period to remove blood residue.

The common method is to boil it for 3 to 10 minutes in a saucepan. The recommended temperature is 140 °C so any microorganisms die.

The pot must be deep enough so that the cup is completely submerged. Once the boiling is complete, turn off the burner and wait for the water to cool before removing the device. Don’t neglect this process, because if it evaporates, the silicone could burn or melt.

Another way to sterilize the product is with exclusive modern devices. They consist of portable, collapsible containers that you fill with water and into which you insert the cup to boil in the microwave. In this case, follow the manufacturer’s instructions.
