The scientific reason behind your bad smelling activewear and easy DIY solutions

Why does your activewear stink and what can you do about it?

Life

Do you ever take your laundry out of the dryer and realize that your activewear still smells bad? Sometimes it feels like no amount of laundry detergent or scented fabric softener will get rid of that funky smell that lingers in all of your workout clothes. The reason this happens isn't because your washing machine isn't strong enough to get rid of the sweat from your run or all the burpees you did, but it's actually the fabric. Most workout clothes are made from synthetic fabrics or cotton, two materials that are great for working out in, but really bad at getting clean. Luckily there are a few ways to get rid of that smell that doesn't involve lots of harmful chemicals. So instead of throwing those smelly clothes away, check out some of our easy non-toxic cleaning methods and DIY solutions!

Why do workout clothes trap smell?

Most people think that the reason their workout clothes stink is because there is sweat trapped in them, but that is only partially true. Sweat by itself actually has no smell at all, but when it comes into contact with the bacteria on your skin, the sweat gets broken down and releases the typical body odor smell (1). So that means there isn't excess sweat trapped in your clothes, it's bacteria, along with dead skin cells and natural particles that are all contributing to the bad smell (2).

There is also a difference in how natural and synthetic workout clothes are affected by this bacteria. Natural fibers like cotton are more affected by sweat and bacteria compared to synthetic fibers because the bacteria that becomes trapped within the fabric can actually start to break down and degrade your clothes. The fibers of cotton are made completely of cellulose, a natural component of plants, and the bacteria can consume this substance and break down the clothes. Cotton is really good at absorbing sweat, so that means there is bacteria deep inside the cotton fibers and the bacteria can quickly multiply due to their massive food source i.e. your clothes. So not only will the bacteria in your sweat make your natural workout clothes smell bad, it will also degrade them over time until they fall apart (2).

Synthetic fabrics, on the other hand, are man-made fibers that are derived from petroleum products. Think plastic threads. Fabrics like spandex, polyester, and nylon are all made of synthetic materials and they are often marketed as sweat wicking or having a cooling effect. These types of fabrics collect bacteria in the space between the fibers, but does not absorb the sweat or bacteria in the fibers. These small spaces where the bacteria are trapped are really hard to access with standard cleaning products making the smell linger (2).

What makes it worse?

To get rid of the smell a lot of people use more detergent or heavily scented fabric softeners, but this only temporarily covers up the smell. These products coat the fibers and fill up the space between them, creating more and more build up the more you wash the clothes. Having build up on your clothes can trap the bacteria and every time you work out more bacteria will start to grow on your clothes.

Traditional detergents were made for traditional fibers like cotton, so when trying to get spandex or polyester fabrics clean, these detergents often aren't strong enough to penetrate deep into the synthetic fabric. Also sometimes your washing machine might be too big or too full and isn't able to clean the clothes effectively. The good news is that there are some non-toxic products and DIY methods that will really deep clean your clothes and make them smell brand new!

What can you do?

First things first, before you get into the products and DIY solutions, try some of these simple ways to avoid having stinky workout clothes in the first place. Sometimes all it takes is changing the temperature or washing your clothes a little sooner. But if none of these work, check out the special products and DIY solutions that are sure to get your clothes squeaky clean!

  1. Don't overfill your washing machine.
  2. Don't use extra laundry detergent.
  3. Stay away from fabric softener.
  4. Wash clothes as soon as possible after working out, don't let them sit wet.
  5. Always wash workout clothes in cold water.
  6. Use a powdered detergent to prevent buildup.

8 Non-Toxic Hand Soaps

Wash your hands with our top picks

Washing your hands is the most important thing you can do to protect yourself from any viruses and other sicknesses that are going around. It's also an important way to remove toxic chemicals like flame retardants that might be on your hands so that you don't accidentally ingest them when you snack or eat a meal. We would take washing hands with ANY soap over not washing your hands, but it might be nice to have some non-toxic hand soaps at home since you use them multiple times a day. Hands soaps can have harmful and unnecessary preservatives or unnecessary ingredients like synthetic fragrances or other things that irritate your skin. We also love bar soaps, but it's nice to have liquid hand soaps around, especially if you have kids. We researched and read reviews of a whole bunch of non-toxic hand soaps so that you can be sure that you are getting your hands clean without any unnecessary chemicals. They come in a variety of amazing smells or you can go fragrance free too! Pick some up today!

Also, just a quick reminder that proper hand washing involves getting into every nook and cranny of your hands, including between your fingers and around your thumbs! It should take at least 20 seconds if you're doing it right.

Some specifically say they are for baby, others have versions for baby along with the original and both are safe, so choose what you like, and know they really are all safe for any age. You don't necessarily need a baby specific detergent. Choose what you think works best for you. And, while you're at it, check out our roundup of fabric softeners and dryer sheets.

Flame retardants. These chemicals are in a ton of consumer products, but they’re not so good for your health. Flame retardant chemicals can easily move from a product onto our skin. ⁣ A recent scientific study has shown that increased household cleaning 🧹or hand washing 🧼(or both! ) can reduce your exposure to flame retardants by half. Removing dust and washing hands before eating are key in reducing the amount of chemicals you’re exposed to. A new reason for spring cleaning! ⁣ .⁣ .⁣ .⁣ .⁣ ⁣ ⁣
But even if it’s #oneofthosedays and no one has left the house, kids should definitely wash their hands before eating. Chemicals like flame retardants and lead can be found in household dust. Kids that crawl/play on the floor and eat with their hands can have more dust exposure than adults. To make hand washing more fun for little ones, try using one of our recommended hand soaps or wash while singing a silly song- as long as you sing for at least 20 seconds!
