Water bottles
Many health experts recommend keeping a bottle of water at our desk every time because this way we will stay hydrated for a long time. But if you drink directly with your mouth without using a glass then you are spreading some bacteria that will multiply in that humid area.
Some studies from the University of Calgary have shown the fact that unwashed water bottles are infected by fecal bacteria and other mold microorganisms. These microbes are introduced by our mouth and once they got there, continue to multiply. It seems that more than 60% of these microbes can lead to severe infections, such as E. coli.
So, all you have to do is to use a glass when you drink water or if you want to take advantage of water bottles, then you should wash it daily – as you normally do with glasses. You should wash them with liquid soap and hot water.
