Millions of people in France buy plastic water bottles. Some of them, rather than buying them constantly, then use them to fill them with tap water. They see it as an eco-responsible practice.
In a way, it is, in fact, more environmentally friendly than using each bottle only once. But from a health point of view, it’s a habit that we advise you to stop immediately. Indeed, it presents obvious risks, which numerous studies highlight.
The dangers of plastic water bottles
Plastic water bottle reuse involves refilling and reusing bottles originally designed for single use. However, Plastic bottles are among the most polluting waste. Indeed, they contribute significantly to ocean pollution.
So, to cleanse their conscience somewhat, some consumers use them more than once. But, without knowing it, they take health risks. The culprit is: polyethylene terephthalate. This is the plastic present in these bottles, which deteriorates as soon as the bottle is opened.

Drinking a bottle of water opened after this time is dangerous for your health, according to this doctor
Although bottling is subject to strict standards in France and Europe, daily use by the consumer exposes the water bottle to various contaminantsespecially those coming from saliva. With each reuse, bacteria can proliferate due to repeated handling, which can potentially endanger the health of users.
Avoid Reusing Water Bottles
During an intervention on RTL, doctor Jimmy Mohamed recalls why it is important to throw away a plastic water bottle after 24 hours. It tells us that plastic degrades quickly once exposed to air.
To support his remarks, he cites studies which show that the longer a bottle is opened, the more plastic microparticles are found in the liquid it contains. This also applies to carbonated drinks, where carbon dioxide escapes after opening, leading to a loss of fizz and flavor.
So forget this behavior that you consider responsible from an ecological point of view. Plastic water bottles are intended to be used only once. They should not be refilled, with water or otherwise.
The dangers of cleaning with hot water
Additionally, we strongly advise against cleaning these plastic water bottles with hot water. This practice, far from being without risk, could release toxic substances such as bisphenol A and phthalates. However, the latter have disruptive effects on the hormonal system.

Having a bottle of water in your vehicle represents a real unsuspected danger
More generally, purchasing plastic water bottles in a country where running water is available is not necessary. And even less when we know the risk. So, we advise you to turn to healthier options.
To do this, choose reusable bottles made from more durable and safe materials, such as glass, stainless steel or aluminum. Che options are both practical, durable and environmentally friendly. In addition, they do not present as serious risks to your health.
