Remember all those articles you used to see in social media about how dryer sheets could kill you? The theory sounded reasonable. Unlike detergent, the chemicals linger in your clothes after washing and the heat from the dryer makes them seep into your skin and inhale them as you breathe. The chemicals listed in these articles have all been linked to respiratory issues, cancers, and all the other awful things we are afraid of.
Except, a lot of the chemicals these articles cite aren't even present in fabric softener or dryer sheets.
Dryer and detergent sheets are subject to the same rigorous standards as household cleaners, but studies are constantly ongoing into safety concerns around the chemicals we interact with. The most common source of information that scare articles cite is a study in 2010 by Dr. Anne Steinemann, but the articles fail to differentiate between dryer sheets specifically and other products featured in the same study. Also, the study was often conducted by collecting self-reported statistics, which are notoriously difficult to verify. But in the end, most of the chemicals cited as a danger aren't actually in most dryer sheets.
It's a natural thing to be concerned about the things that we are exposed to. Our health is important to all of us and there are a lot of chemicals in the products we keep in our homes that we don't necessarily understand. But it's also important to remember that a lot of bad science out there capitalizes on those fears for profit. If you prefer to switch to a more natural alternative for your laundry needs that's totally fine, but always be careful about what you read on the internet.
Including this, obviously.
