How long should you wear underwear before throwing it away? Revealing the 'maximum lifespan' of underwear.

Most sophisticated women tend to spend a lot of money investing in luxury clothing, cosmetics, and skincare products, often overlooking the fact that their most intimate wear, "underwear," is actually the most worthy investment. The condition of our intimate clothing is closely related to our health, and it's not enough to think that changing and washing them regularly will ensure cleanliness and hygiene. In fact, old underwear can be dirtier than you imagine, increasing the risk of contracting gynecological diseases. Do you know that there is an optimal period of use for underwear?


Although you may wash your underwear thoroughly, it's still important to periodically replace them.

Underwear often comes into contact with our intimate areas and daily secretions and excretions. Regardless of whether it is hand-washed or machine-washed and washed thoroughly, after prolonged use, underwear will have trace amounts of feces and large amounts of bacteria attached and parasitic.

How dirty can underwear really be?

A study suggests that within a year of normal washing and replacement, there are 10,000 bacteria attached and parasitic to underwear. Additionally, a dirty pair of underwear on average carries 0.1 grams of feces, which may contain 10 million viruses. This is quite scary! Wearing underwear for more than a year can increase the chances of getting gynecological and skin diseases. Furthermore, using underwear for a long time and washing it frequently can damage the fiber of the underwear, making the material dry, hard, and less elastic, and even yellowing. This will also make the breathability and moisture absorption of the underwear worse. Underwear also have an expiration date!

After long-term use, underwear is susceptible to bacterial growth, which can cause repeated infections in private areas. For the sake of cleanliness and health, it is recommended to replace them regularly. So, how often should you change your underwear? Here are some suggested guidelines for the lifespan of different types of underwear:

-Regular everyday underwear: Replace after 40 washes
-Occasional wear underwear (worn once a week): Replace after 6 months
-Menstrual cycle underwear: Replace after 15 uses
-Sports-specific underwear: Replace after 20 uses

Apart from regularly changing your underwear, how can you choose the right underwear?

In terms of material, pure cotton is a soft, skin-friendly and moisture-absorbing material, which is considered the healthiest material due to its low irritation and allergenic properties.

In terms of function, underwear with effective antibacterial properties can help inhibit the growth of yeast, E. coli, and Staphylococcus aureus, reducing the risk of infections in intimate areas.

Size-wise, it is important to choose the right size to avoid tight-fitting underwear that can cause discomfort and excessive friction in the intimate area.

For style, it is recommended to choose triangle or flat-footed styles and avoid wearing T-back or thong styles as they tend to move around and can spread bacteria from the anus to the intimate area, increasing the risk of bacterial infections.
