Research shows that even freshly washed underwear can contain bacteria. Although it’s considered one of the most basic hygiene habits, the issue of wearing and maintaining underwear is often controversial – and for good reason. Many studies and advice on the Internet warn that even freshly washed clothes can contain germs, which causes many people to worry and ask: How long can we actually wear the same underwear before it needs to be replaced?
It is common knowledge that underwear should be changed daily to avoid unpleasant odors and possible health problems. However, despite regular washing, it is not possible to completely remove all microorganisms. According to a microbiological study by Dr. Charles Gerba, even washed laundry can contain very small amounts of fecal residue, and thus bacteria such as E. coli. However, experts emphasize that such amounts do not necessarily represent a health risk for healthy people.
The myth of six months
Claims that underwear should be thrown away after six months or at the latest after a year are not based on scientific facts. If you take care of it properly and you don’t have health problems, it can be worn for much longer.
Key signs that it’s time to replace are a persistent unpleasant odor or discoloration that doesn’t go away even after repeated washing. The issue of washing temperature is also important. Experts state that washing clothes at 30 degrees is completely sufficient for everyday hygiene. A certain amount of bacteria will always remain on clothing, regardless of the temperature, and new ones will still be transferred to it as soon as it comes into contact with the skin.
When should the temperature be increased?
Exceptions are situations when a person suffers from infectious diseases, such as fungal infections, the so-called athlete’s foot or norovirus. In these cases, it is recommended to wash underwear and other worn clothes separately, at 60 degrees, using stronger detergents. If the fabric does not tolerate high temperatures, the solution may be hygienic rinsing (disinfection for laundry), which effectively destroys viruses and molds.
