“If you’re ill and deposit a nasty glitch in that glass and it doesn’t dry properly before “youre using” it again, there might be enough time for that bug to replicate enough to cause your illness again, ” said Aaron Margolin, PhD, a prof of microbiology at the University of New Hampshire.
The source of the water you’re sipping can also make a difference: Unlike tap water, bottled and well water don’t automatically come with added chlorine to help halt the growth of bacteria. And if it’s a shared cup, look out! All those bacteria, viruses, and intestinal parasites passing back and forth could entail stomach ulcers( politenes of Helicobacter pylori bacteria) or projectile vomiting and explosive diarrhea( politenes of norovirus ).
“The more people who use that same cup, “the worlds largest” the probability that one of those people carry bacteria that might attain you sick, ” Margolin advised.( Speaking of gross: Here are the 8 germiest public places you touch .) What will probably happen : A whole lotta nothing, especially if you’re the only one using the glass.
“It’s important to mention that pathogensthose organisms that construct you sickdon’t merely seem out of nowhere; they have to be introduced by someone or something, ” Margolin said.
The fact that it’s a glass , not a plastic beaker, entails it won’t degrade over day, making nooks and crannies where bacteria can build up. Plus, glass is more likely to completely dry, and drying, also known as desiccation, is an excellent way to halt the growth of bacteria, Margolin added. What’s more, if you’re filling up with tap water, most therapy plants use chlorine to zap dangerous contaminants that work both on the water and your saliva.( Still drinking soda ?

Bottom line : “If you restrict the usage of the cup to a single individual and you make sure that the water is clean, then you are not going to get sick if you use the same cup over and over, ” Margolin said.
