Refilling single-use plastic water bottles is bad for your health
the verdict
SUPPORTED
the evidence backs this
confidence 65/100
Multiple recent reviews and scientific studies indicate that single-use plastic water bottles shed micro- and nanoplastics into drinking water, which can lead to cellular uptake, oxidative stress, and potential long-term health risks upon ingestion, though some exposure assessments suggest the immediate toxicological risk is low.
