World map of tap water drinkable by all

Did you know that there are 187 countries in the world where tap water isn’t safe to drink for everyone? It may be drinkable, but not for everyone, as their body isn’t used to it.
Check the map and remember that, if you visit the countries in the blue area, you can drink with no risk; if you go to a country in the red area, it’s better to drink bottled water, or purify the tap water before drinking it, otherwise your body may react badly!

Drinking water is healthy, but be careful, not all waters can benefit our body!
