– Why is it bad to use my water bottle for multiple days without washing it?

Question

I either drink it all or I dump it and put fresh water in. What are the risks if I don’t wash it? It’s just me drinking out of it. I’m talking days and days like why ever wash it if it’s just me?

Edit: Clarified the amount of time without washing

There is bacteria in your saliva and it could hang out in your water and reproduce. Also your bottle might get residue stuck on the inside.

There’s not much risk if you wash your water bottle every 3 days. Or 7 days, tbh. But simply not ever washing it could potentially eventually get you sick.
