When it comes to underwear, there are certain things you should definitely steer clear of. Are you primarily buying your underwear based on looks? If so, you should also consider these crucial factors to avoid putting your health at risk.

1. Cotton Underwear

Cotton panties might not be the most aesthetically pleasing choice, but they are the healthiest. Compared to synthetic fabrics, cotton is breathable. Synthetic materials struggle to absorb moisture properly, increasing the risk of bacterial infections. If you do opt for synthetic underwear, make sure there's at least a cotton insert in the crotch area.

2. String Thongs

String thongs, those barely-there pieces that leave no visible lines, are perfect for tight-fitting pants like yoga pants. However, string thongs have their downsides that should not be underestimated. The thin strip of fabric can easily shift in the intimate area, potentially transporting intestinal bacteria into the urethra. This can lead to inflammation and yeast infections. Experts recommend choosing cotton string thongs and wearing them for short durations only.

3. Bedtime Underwear

Please, don't! That doesn't mean you have to sleep naked, but you should avoid wearing tight underwear at night, especially if you're prone to infections and inflammation in the intimate area. Moisture collecting in the intimate area overnight due to sweating can promote the growth of yeast bacteria. Therefore, it's better to go without underwear under your pajama pants or nightgown to allow your vagina to get enough fresh air.

4. Skipping Underwear During the Day

The "commando" motto applies only to nighttime. During the day, you should always wear underwear to protect your vagina from friction and dirt. For example, going commando in jeans can irritate and chafe the intimate area due to fabric fibers and dyes if you don't change your underwear daily.

5. Wrong Sizing

Underwear that digs into or sags in the crotch is simply uncomfortable and annoying. Therefore, when purchasing underwear, be sure to pay attention to getting the right fit. Too-tight panties can chafe the skin and limit airflow to the vagina, while overly large underpants can facilitate the transport of bacteria. Both scenarios have unpleasant consequences for your intimate area.

6. Colored Underwear

In addition to plain black and white underwear, it's great to have some colorful options in your drawer. However, experts caution that the dyes in colored underwear can irritate the sensitive skin around the vagina. When buying, opt for high-quality and slightly more expensive (cotton) models. If it has lace, make sure it's only on the edges of the underwear and not in direct contact with the vagina.

7. After Exercise

After finishing your workout, it's important to change your underwear immediately. While there's usually no risk of internal infection, the outer area can become irritated. Itchy rashes can result, which can be avoided by switching to fresh and dry underwear after exercise.

8. Using the Dryer for Underwear

If you want to prolong the lifespan of your underwear, consider hand washing it or at least avoid using the dryer. Heat can destroy elasticity and make the elastic bands in the fabric porous. This causes underwear to lose its shape quickly. So, allow your underpants (and bras) to air dry on a line.

9. The Wrong Detergent

Because the intimate area is more sensitive than, for example, your arms, you should use a special hypoallergenic detergent for your underwear. These detergents are free from additives and fragrances, offering better protection for your vagina.

10. Shapewear

So-called "fat-reducing" underwear can flawlessly conceal minor curves under tight clothing, making it the perfect solution for a night out. However, you shouldn't wear this special underwear every day. "Squishing" the skin and organs can lead to a range of serious problems, such as incontinence or, in the worst-case scenario, organ failure.
