Antimicrobials, or anti-your-health?

Why you should rethink buying antimicrobial products

You know it's coming, the dreaded flu season. Maybe you've tried investing in an antimicrobial mattress, shower curtain or probably the most common, soap, to try and prevent those germs from making you and your family sick. They just seem so promising, with their claims of preventing 99.9% of all germs. But, are they actually keeping you safer? Based on new research, the Food and Drug Administration (FDA) released a statement on why antimicrobials might not be the best way to fight off germs. We'll break down everything for you.


What are antimicrobials?

First things first, antimicrobials are NOT the same thing as antibiotics. Antibiotics are medicines used when you are sick with a bacterial infection, and should definitely be taken fully if prescribed by your doctor, even if you start to feel better after the first couple of days. Antimicrobials, on the other hand, were originally designed by companies who thought that adding in an antimicrobial agent would boost the effectiveness of soaps. The most common ingredient in these antimicrobial products was triclosan (an antibacterial and antifungal agent) which has since been phased out in hand soaps due to FDA regulation (1). Triclosan was phased out over concerns that animal and cell studies show the chemical can impact hormone signaling and other biological processes (2).

Where can you be exposed?

Like we mentioned before, triclosan was first introduced in soaps. Since then, antimicrobials have spread to shower curtains, mattresses, apparel, toothpaste, paint, art supplies, and essentially anything that could have the ability to harbor more germs than usual. Manufactures have included antimicrobials into many of these products because of their tendency to act as a perfect environment for bacteria and mold when they come into contact with water (or sweat!). Even though triclosan has been phased out in hand soap (you can still find it in toothpaste!), it is still allowed in hospitals and food service industries. What is even more concerning for consumers is that companies are replacing triclosan with other antimicrobials that may potentially have the same toxic health effects, if not worse.

Are antimicrobials even effective?

Actually, not at all! In studies conducted, soaps containing triclosan and soaps without triclosan performed exactly the same and prevented the same amount of sickness (2). Even though they sound promising, no amount of antimicrobials will be able to prevent mold and other bacteria from growing on mattresses or shower curtains if they are not properly ventilated and washed. In addition to this, overusing antimicrobials can actually make it harder for doctors to treat you when you are truly sick. Antimicrobials are causing a rise in the number of superbugs, or bacteria that are resistant to antibiotics. Using antimicrobials when we don't need them makes these bugs resistant to antibiotics, so when we do need antibiotics to treat diseases, they don't work. Basically, by using too many products full of antimicrobials, we are helping the bacteria practice and get stronger at fighting against our best defenses. Sounds like a pretty awful deal for something that doesn't really work, right?!

What should I do then?

Our best advice is to stay away from antimicrobial-containing products, period. Since you can't really prevent antimicrobial exposure in hospitals and food service areas, removing it from your household is a good way to limit your contact. Lucky for us, products containing antimicrobials are usually labeled since companies use it as a selling point and make sure to brag about the fact that their product contains antimicrobials. So if you see one, just put it back on the shelf and buy one that is antimicrobial-free. For household items like mattresses, shower curtains, and clothes, making sure these items are in well ventilated areas and washing them when needed are great ways to make sure gross germs don't grow in the first place.

This little change will make a BIG impact. Staying away from antimicrobial products not only protects your health in the long run, it also ensures that antibiotics will work for you when an infection really hits.

Everyone has their favorite water bottle - a Camelbak with the chewy straw, or a new shiny S'well bottle, or the Hydroflask that keeps your drink icy for days. And, we know that reusable plastic water bottles have some perks- lightweight, see through, indestructible- but they also have one big drawback, the plastic. Plastics, even ones that are BPA free, are often made of chemicals that can seep into water and affect your health. So, that's where this big question comes into play. Do I have to (or should I) ditch my beloved Nalgene with all my stickers from travels throughout the years?

Our answer is - you don't have to pitch it, but it probably shouldn't be your primary bottle either. You can stop reading here and check our our roundup of a dozen glass and stainless steel reusable water bottles if that's enough info for you, or you can keep reading and well give you some tips and nuggets of info on why those tips will make a difference.

A Dozen Reusable Water Bottles

Our top picks for glass and stainless steel water bottles

If you've made it here, you probably already know that bottled water isn't great. Plastic in general can also be tough because of the ever popular BPA and it's sister chemicals. So, we collected 12 of our favorite plastic-free, reusable water bottles so you don't have to go hunting. Many of these brands make many types of bottle and cups. Feel free to poke around to find a size or shape that might work better for you, but keep in mind always go for glass or stainless steel. That assures that even if the plastic bottles are BPA free, you won't have to worry about BPA replacements. It's often tough to find bottles without plastic lids, but if the water isn't constantly touching the lid, a plastic lid usually isn't something to get too worried about.

If you have some old plastic reusable water bottles kicking around (who doesn't!) then check out our advice about how to use them safely.

Having Trouble Keeping a Healthy Weight?

Here's why chemicals might be keeping you from shedding those last few pounds

If you're eating healthy, getting lots of sleep, but just can't seem to hit a healthy weight, it might be something you've never thought about. Obesogens, a term coined in 2006 to refer to chemicals that cause us to gain and hold on to weight, and can influence weight loss. Now, we know that maintaining a healthy weight and lifestyle is influenced by what seems like a bajillion factors, and is a complicated issue with no easy solution. But, it looks like obesogens are a piece of the puzzle and definitely something you want to be aware about. Data shows that obesity is an increasing problem. Over one-third of both adults and children in the U.S. are obese or overweight (1, 5). Even for people who regularly work out or have superhuman strength to say no to desserts, obesogens are having an impact. Unfortunately, as obesogen research is in its early stages, we still don't know everything about these chemicals and how they affect weight gain, but as of now, here's what we do know.

Cleaning is important, you should definitely do it. While it can be a not very fun chore, unless you relate to Monica on a spiritual level, it really is something that should be done regularly. Besides germs, cleaning removes all the yucky (and potentially chemically laden) dust and dirt that can collect in your home over time. While it might seem like you should also disinfect your surfaces when you clean to kill any crazy germs that might be hanging out, it's not as necessary as you might think. And, using a strong, commercial disinfectant is definitely not needed or advised. Do you really want to use something all over your home that comes with a huge caution or warning sign on it?
