Polyester is a synthetic fabric that is often used in athletic wear due to its durability and moisture-wicking properties. While it has some advantages for exercise, it also has some potential major drawbacks.

One of the main concerns with wearing polyester for exercise is that it does not allow for adequate ventilation. When worn during physical activity, polyester can trap heat and moisture against the skin, which can lead to skin irritation, rashes, and fungal infections. This can be especially problematic for people with sensitive skin or those who are prone to skin irritation.

Plus when working up a sweat during your workout, your open pores on your skin (your largest organ) can absorb some of the harmful chemicals from clothing treatments during production. It’s crucial to wash all of your clothing on purchase.

Additionally, some studies have suggested that polyester can release harmful chemicals, such as microplastics, when washed. These microplastics can end up in the water supply and harm aquatic life.

It’s important to note that not all polyester fabrics are created equal, and some may be treated with additional chemicals to make them more breathable and reduce the risk of skin irritation. It’s also worth considering alternative fabrics, such as natural fibers like cotton or bamboo, which tend to be more breathable and less likely to cause skin irritation.

So while polyester can be useful for certain types of exercise, it’s important to consider the potential drawbacks and choose the right type of fabric for your needs.
