8 Common Mistakes You May be Making with Your Underwear Without Realizing It

28 January, 2019
As well as choosing items made of breathable fabrics, it's essential to change your underwear every day and even twice a day if you go to the gym to avoid infections.

Underwear is one of the most important items of clothing. We could even consider it a second skin.

The problem is that sometimes we let ourselves be led by different fashions and we end up making mistakes that affect our well-being.

In this article, we’ll take a look at 8 common mistakes you may be making that can affect your health.

1. Don’t wear tight underwear

If you tend to wear very tight underwear, then you’ll know that it can cause infections or irritation. This is because bacteria grows and thrives in warm environments. The tighter your undergarments, the more likely of bacteria growth.

For men, is it harmful to testicular health and can even reduce fertility.

Choose loose underwear. If you like, you can wear tight underwear on occasions, but don’t let it become a habit.

2. Avoid thongs

Thongs are not a great choice either if you want to stay healthy.

Due to the inevitable rubbing that the string tends to cause, the vagina and anus end up coming into contact because of the string of the back part of the thong.

 Therefore, this part of the fabric of the thong can lead to the transmission of bacteria between the anus and the vagina. All this can lead to vaginal infections.

3. Wear underwear made of breathable fabrics

Underwear should always be made of breathable fabrics so that it is as comfortable as possible.

Avoid underwear made of silk or lycra. While they may seem much sexier, you must remember that these fabrics are not breathable and the skin of the genitals needs to breathe.


The best thing is to choose undergarments made out of cotton, which will help you to avoid infections. As with tight underwear, you can leave the silk and lace for special occasions.

4. Not changing it every day

Underwear must always be changed every day. If you sweat, you should change even more often. Sweaty or dirty underwear stops protecting your intimate parts from bacteria, so you need to bear this in mind.

Also, if you’ve already put on a fresh change of underwear and you go to the gym, it is advisable to change afterward. Again, this is to prevent the bacteria growth and to stop infections.

5. Be careful what products you use to wash your underwear

Some chemical products that are sold for washing underwear can be irritants, so you should be careful about using them and go for other options.

This way, you’ll avoid skin problems like irritation and infections.

Don’t be deceived by a fresh floral aroma and pay attention to the chemicals they contain. These can damage the sensitive skin of your genital region.


The best option is to use natural white soap or unperformed detergent.

6. For those who don’t wear underwear…

If you’re one of those people that don’t wear underwear, you should at least bear in mind a series of hygiene precautions that should never be overlooked.


You’ll have to apply all the above-mentioned recommendations to the clothes you wear that come into contact with your intimate zone.

Pay special attention to the seams to avoid them rubbing against your skin and causing irritations.

7. Sleeping in underwear

Do you sleep in underwear? Perhaps you should reconsider it.

According to a study carried out in 2012, the excess of heat in the intimate zone can damage the quality of sperm for men and can cause bacteria growth for women.

Don’t forget to let the genitals breathe and transpire as they need to during these hours of rest.

8. Your underwear is not your pocket

Have you ever used your bra to carry money or a piece of paper? This is harmful to your health because of the number of bacteria that can be found on bills.


Don’t use your undergarments as a place to store your personal items. Whether it be your phone or your money, do yourself a favor and keep any extra bacteria at bay.

In conclusion

The best thing is to keep your underwear and undergarments clean and dry and that you choose breathable fabrics. 

It’s healthier to always wear underwear, and if you want a break from it at any time, make it at night.

Remember that these recommendations are especially important when exercising. During exercise, the skin comes into more contact with the dampness and bacteria and this is when an infection can start.
