It is recommended to drink bottled water when traveling abroad to avoid the risks of contamination by pathogens present in tap water, which can cause gastrointestinal infections.
In some countries, tap water is not always treated or purified properly. This means it may contain harmful microorganisms (viruses, bacteria, parasites) that can cause digestive issues or other unpleasant health problems. These germs can come from poorly maintained water systems or inadequate sanitation. Even clear and transparent, water can hide invisible dangers, like the infamous traveler's diarrhea, which can quickly turn a vacation into a real nightmare. To avoid these risks, it is better to opt for bottled water when traveling!
Each country defines its own criteria for judging whether tap water is potable or not, and this variation implies that what is safe to drink in one country can become risky in another. In Europe and North America, standards are generally strict, with frequent and precise checks to detect any contamination. However, in some developing countries, checks are less frequent and tolerance thresholds for certain contaminants, such as bacteria or chemicals, may be higher or less consistently enforced. As a result, even if the water is officially potable according to local standards, it may contain elements that trigger unexpected intestinal issues in travelers.
If you consume contaminated water, you expose yourself to many unpleasant diseases like traveler's diarrhea, cholera, or typhoid. Drinking sealed bottled water greatly reduces this risk, as it is treated and tested. It helps avoid bacteria, viruses, and parasites lurking in tap water. It's a simple and highly effective way to avoid ruining your vacation in bed or in the bathroom.
Buying bottled water abroad is generally very simple, as it can be found almost everywhere: supermarkets, hotels, shops, or street kiosks. Moreover, it is quite inexpensive and often saves you the hassle of looking for a reliable source of drinking water. Having a bottle on hand helps avoid unnecessary stress when you're thirsty in the middle of a walk. In terms of practicality, bottled water is ideal: it comes in resealable bottles, is lightweight, and portable, making it a safe and convenient solution for staying hydrated without taking unnecessary risks.
International health authorities, such as the WHO, as well as national ones (Ministry of Foreign Affairs, public health agencies), clearly advise travelers to favor bottled water with a seal rather than tap water. This advice is especially relevant if you are traveling to regions where sanitary conditions are questionable. Even brushing your teeth with bottled water is often recommended in certain countries. These guidelines aim to simply limit any risk of intestinal infections or traveler's diarrhea, which are very common among tourists who drink local water without caution.
Adding a few drops of fresh lemon juice to drinking water is not enough to make it safe if it is contaminated. Contrary to popular belief, lemon does not kill enough bacteria or viruses present in the water.
Bottled sparkling water is often a safer option than still water in certain countries, as its carbon dioxide creates a slightly acidic environment that is less conducive to the growth of bacteria.
In case of an emergency without access to bottled water, boiling water for at least one minute (three minutes at high altitude) effectively eliminates most potentially harmful bacteria, viruses, and parasites.
Today, there are portable filtration bottles specifically designed for travelers, capable of filtering up to 99.9% of bacteria, viruses, and parasites present in tap water.
Among the most common illnesses are traveler's diarrhea, cholera, dysentery, typhoid, and hepatitis A. These diseases typically result from water contaminated by pathogens (bacteria, viruses, or parasites).
It is recommended to consult the official recommendations issued by the health or tourism authorities of your country of origin before your departure. In case of doubt, always opt for bottled water that is sealed and unopened, or water that has been boiled for at least one minute.
This largely depends on the chosen destination. In regions known for health risks related to water, it is advisable to prefer the use of bottled or treated water, even for brushing teeth, in order to avoid any risk of accidentally ingesting contaminated water.
Yes, it is strongly recommended to always check that the cap of the water bottle is intact and sealed before consuming its contents. This check helps prevent the risk of using reused bottles filled with non-potable water.
Sure! Here’s the translation: "Yes, but it is recommended to carefully check that the filtration system used effectively removes bacteria, viruses, and parasites. Some portable filters certified specifically for travelers can be a reliable practical alternative to bottled water."
