Ana Molina, dermatologist: "Why do you smell great in some shirts, but in others... you run away from yourself?"

It's not always the fault of sweat or deodorant. According to dermatologist Ana Molina , there's a scientific reason why some clothes seem to increase body odor while others don't: the fabric they're made of . The clothes we choose have a significant influence on how we smell throughout the day.

"The type of fabric you wear influences how you smell," says Molina, who has shared a practical ranking of materials to help you choose clothes that are not only comfortable but also kinder to your nose.

Wool takes the cake . According to the specialist, this material is the most effective at preventing unpleasant odors. "It has a natural antibacterial action , so it prevents the growth of odor-causing bacteria," she explains. It also regulates temperature very well , which also reduces sweating.

Linen comes in second, thanks to its high breathability . It's a cool, lightweight, and quick-drying fabric , ideal for hot days or for those who tend to sweat more.

Cotton is a popular and affordable fabric for everyday use. Although it's comfortable and quite absorbent , it has a weakness: it takes longer to dry , which can encourage bacterial growth if moisture builds up.

And what's the worst fabric for keeping odor at bay ? "Without a doubt, polyester ," says Ana Molina. Nylon is a close second. Both are synthetic fibers that don't allow the skin to breathe properly and trap sweat , creating the perfect environment for bacteria to multiply and generate unpleasant odors.

For those who can't avoid wearing synthetic fabrics, the dermatologist recommends washing these garments after each use and, if you want to go a step further, adding a textile disinfectant to the laundry. This small gesture can make all the difference .

So if you've ever noticed that you smell better in one T-shirt than another, it's no coincidence. As Ana Molina humorously reminds us, "It's not your imagination or the deodorant, it's your clothes." Choosing the right fabric can be the first step to feeling fresh all day long.
