Investigates claims that reusing plastic water bottles is dangerous
Reusing Plastic Water Bottles Drinking from a plastic water bottle is an easy way to get the water your body needs.
Reusing a plastic water bottle is even more convenient. But is using a plastic water bottle in this way safe?
This article investigates claims that reusing plastic water bottles is dangerous.
There are a few alleged problems with the practice, each of which will be dealt with in order.
First is the idea that over time bacteria (and possibly fungus) will proliferate to a dangerous degree in a plastic water bottle.
It is true that each drink out of a water bottle will inevitably transfer some bacteria to the bottle.
Also, that bacteria can flourish inside of water bottles — but does this pose a serious risk?
The theory is true — as far as it goes.
However, there’s no reason that bacteria should be allowed the time to duplicate.
Simply wash out your water bottle with soap (and dry it, too, since moist environments are ideal breeding grounds for bacteria).
After every use and the chances of bacteria growth will be minor.
Just think of your plastic water bottle as an ordinary dish. Would you reuse a cup or plate without cleaning it?
Of course not — so treat plastic water bottles the same way.
The second supposed risk of reusing plastic water bottles is that over time harmful, toxic chemicals will bleed out of the plastic into the water.
Scary as this sounds, there is no good evidence that such a migration from the plastic to water is possible.
Although one study claimed to show that a certain carcinogen was escaping from plastic bottles, this study was not subject to peer review and did not fulfill basic scientific rigor.
Numerous other, more thorough studies have since debunked the claim, and the FDA has ruled that the substance alleged to pose a threat can be safely brought into contact with food.
A related theory claims that if frozen, plastic water bottles will secrete a toxin called dioxin.
Again, there is no evidence to suggest this is true
. Firstly, dioxins can only be released at extremely high temperatures (over 700º) — and, more importantly, the toxin isn’t present in water bottles anyway.
In any case, the FDA has officially determined that any chemicals that might be released from water bottles at elevated temperatures are done so within the range of safety.
The final spurious claim against plastic water bottles is that leaving them sitting in the sun can be harmful.
The theory is that exposing the plastic to the sun can trigger the release of dangerous chemicals, chiefly a chemical compound called bisphenol A, or BPA.
It is true that the sun can make plastic water bottles leech BPA, and it is true that BPA is dangerous.
However, since the compound is only released in small amounts, it poses no big threat.
Based on hundreds of studies, the FDA has declared that there is no risk of harmful levels of BPA.,
Seeping out of plastic.
So are there any good reasons to avoid reusing water bottles? As it turns out, there are — though they do not involve a risk to health in any way.
Plastic is damaging to the environment
- Producing plastic water bottles requires depleting large amounts of limited, non-renewable fossil fuels.
- That is why millions of barrels of oil are used every year to help make plastic bottles.
- Usually, the majority of bottles are not recycled, even though the technology to do so exists.
If you care about the environment, it’s obvious that you should eschew plastic water bottles.
However, note that such concerns mean reusing the same bottle is actually better than constantly buying new ones.
Of course, it’s better still to not use disposable water bottles at all. Plastic water bottles intended for throw away are inherently wasteful. Using a permanent water bottle made out of glass, plastic, or metal is better.
Whether or not you choose to switch away from disposable plastic water bottles. You should rest assured that reusing those water bottles poses no danger to your health.
The allegations raised against plastic water bottles are all hokum.
As they are based on either unscientific, disproven theories, or research that is now discredited.
