Can you elaborate? Like is it somehow worse to buy a bottle of water and refill it periodically over the course of a year, than to let the original contents sit in my house for a year and then drink it? If so, I'm guessing the extra handling (squishing, crunching) is the main culprit? Or does leeching occur more readily when the contents are refreshed, as opposed to static contents that already reached equilibrium? Or is the pH (or other characteristics) of the original contents less likely to cause leeching than arbitrary contents?
I've heard that handling is the main issue with leeching and also shredding of micro/nano plastics into the water, heat and UV also degrade the plastic. It's worse the thinner the plastic bottle is.
I do drink a lot of bottled water, and while I don't reuse bottles I'm still considering how much just pouring the water from the bottles into a glass would help.
Not OP, but I'd imagine the extra handling is the concern here, as far as water bottles go. You do want to refresh water in water jugs routinely as 'preservatives' like chlorine dissipate.
The better wording of 'stop reusing bottled water bottles' to avoid plastics would be 'use glass or metal water bottles'.
