Underwear may contain little fabric, but its function is crucial; wearing the wrong type can easily lead to illness. The most basic question about underwear is how often to change it.
What are the dangers of not changing your underwear for a long time?
Underwear is the covering for both male and female genitalia, and it also rubs against them. Not changing underwear regularly can easily affect the health of the genitals; for example, women may develop vaginitis, and men may experience scrotal itching.
Don't think these are just minor annoyances. The media once reported a case of a 23-year-old woman who only changed her underwear once a month, felt unwell, and was eventually diagnosed with precancerous lesions of the vulva. Yes, neglecting hygiene in the genital area and wearing improper underwear can actually induce cancer!
How often should you change your underwear?
How often should you change your underwear? Actually, this question has two meanings. First, how often should you wash your underwear?
For both men and women, underwear is closely connected to the genitals. Ideally, one should change underwear every time they go to the toilet to prevent bacteria and other dirt from taking hold. However, this is somewhat impractical in real life; you can't exactly carry several pairs of underwear in your bag to work, can you?
Therefore, it is generally recommended to change and wash underwear once a day, for both men and women. It's important to emphasize that after washing, underwear should ideally be disinfected and dried in the sun!

The second meaning of "how often should you change your underwear" is how long you should wear your underwear before throwing it away and replacing it with a new one: three months? six months? a year?
Actually, it depends on the condition of the underwear. Generally speaking, if the most important part of the underwear has turned yellow, or if the underwear has lost its original elasticity and become deformed, you can throw it away without hesitation!
From purchase to disposal, men's underwear may last for several months, while women's underwear may only last for one period. Therefore, there is no need to be fixated on the specific time frame, but rather on the condition of the underwear itself.
Which type of underwear is better?
Throwing away old underwear means buying new underwear. Do you know what kind of underwear is good for your health?
When buying underwear, the first thing to consider is the material. Cotton is the best choice for underwear, as it's gentler on the skin and offers better breathability and sweat absorption.
Secondly, underwear should fit snugly. Too tight may put too much pressure on reproductive organs, while too loose will not provide adequate protection.
In addition, it's best to avoid underwear that is too brightly colored. While bright colors might add some spice to certain occasions, many of these colors are produced using dyes, and even if they don't fade, they could still pose some health risks.
Some people are also concerned about how many boxers to buy. This mainly depends on personal preference and comfort. However, from a health perspective, it is more recommended that men buy boxer briefs with four corners. This can provide the greatest support for the reproductive organs and prevent discomfort when walking or exercising.
