Ever wondered why your glass of water tastes funny when you leave it out overnight?

Well we now have an answer!

According to D News there’s a reason for the strange taste when water’s left out overnight – and it will probably make you think twice about drinking from that cup!

Being exposed to air, the water absorbs some CO2 which triggers a process that lowers the PH of water, eventually changing the taste.

However, while there’s nothing to worry about from this process, there is another reason why you should consider covering up your glass.

While you’re sound asleep the water in the glass is exposed to “other nastiness” from around your home.

Basically we’re talking dust and bacteria – all of which is settling into your once fresh drink.


Yep, we know.

Anyone else thinking it’s time to invest in a good water bottle?
