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.

And nope, it's not about staying hydrated (okay, one of them is) or putting on a face mask, although both of those might make you feel better when you arrive, too.

Non-Toxic Candle Roundup

They smell even better than they look! Plus no harmful chemicals

Trying to set the perfect mood for Valentine's Day? We've got you covered! Our candle roundup is a great guide to finding the perfect candle. Most candles contain paraffin wax, which is made from petroleum and use fragrance oil. And fragrance can contain a ton of harmful chemicals. Our candles only use natural wax like soy or beeswax, and only contain essential oils! Plus they all smell amazing!



a) Aira Soy Candles
b) Lulu Candles Natura 100% Organic Soy Vegan Wax Candle
c) Big Dipper Beeswax Aromatherapy candle
d) Milk + Honey essential oil candle
e) Pure Plant Home glass candle
f) Edens Garden essential oil candles

Wondering why you need a non-toxic candle? Candles release compounds known as volatile organic compounds whether they are lit or not (1). VOCs can have both short and long term adverse health effects and there are consistently higher concentrations of VOCs indoors than outdoors. The majority of the VOCs released from candles is because they doesn't burn cleanly, which releases acetaldehyde, formaldehyde, acrolein, phenol, benzene, and toluene, many of which are carcinogenic (3). Phenols (one of the words in that list if you jumped to the end of the sentence when you started seeing a bunch of scary words) are the fragrance chemicals that make candles smell like brown sugar, wild mango, and clean laundry. It makes sense that it would take some pretty weird chemicals to bottle up the smell of a tropical island in a single candle, right?

It's definitely healthier and safer to go with candles scented with essential oils to avoid some of these nasty VOCs. A few of the other VOCs released can cause changes to our DNA (and in some cases, bad changes!). Of all of the VOCs released, formaldehyde and acrolein are the other two biggest worries because they are released in the highest concentrations. Formaldehyde itself can cause cancer (4) while acrolein, which is used to make weapons in high concentrations, can kill you if you breathe in too much of it - Yikes (5). I don't know about you, but those are some things I definitely don't want to invite to my relaxing spa night!

Candles are also traditionally and most commonly made of paraffin, which is obtained from petroleum or shale. We recommend candles made from beeswax or soy because they come from natural sources. Some candles wicks may contain lead, so always make sure to look for a "lead-free" wick made from cotton.
