How does reusing plastic water bottles affect the migration of chemicals into water?

Summary

Reusing plastic water bottles may cause them to shed more tiny plastic particles (microplastics) and other potentially harmful chemicals into your water over time, according to a review of existing research. While scientists don't yet have a complete picture of the health risks, this is a good reminder to wash reusable plastic bottles regularly or consider switching to glass or stainless steel if you use the same bottle repeatedly.

While specific evidence on reusing plastic water bottles and chemical migration is limited, available studies suggest reuse can increase the migration of microplastics and hazardous substances, potentially raising health concerns.
