Carry your own steel water bottles.
đ« You shouldn't drink bottled water.
New researsh shows the health risks are chronic and vastly underestimated.
A study has revealed that drinking bottled water daily may expose people to tens of thousands of microscopic plastic particles annuallyâposing potentially serious long-term health risks.
Concordia University PhD researcher Sarah Sajedi analyzed over 140 scientific papers and found that those who regularly drink bottled water ingest about 90,000 more microplastic and nanoplastic particles each year than those who drink primarily from the tap.
These tiny plastic fragments, shed from single-use bottles during manufacturing, transport, and storage, are invisible to the naked eye but may pass through the bodyâs natural barriers and enter the bloodstream and organs.
Once inside the body, these particles can cause chronic inflammation, hormone disruption, reproductive problems, and even contribute to neurological damage and cancer, though many long-term impacts remain poorly understood due to a lack of standardized testing. Sajedi calls for increased public education on the chronic risks of bottled water, emphasizing that it should be reserved for emergencies, not daily use. While global regulations are reducing plastic bags and straws, water bottles remain largely unregulated despite their direct link to plastic ingestion. âThe issue is not acute toxicityâit is chronic toxicity,â Sajedi warns.
