Recycling codes to look out for
These codes indicate what type of plastic was used to make the bottle. So before choosing one, take a moment to check the label.
The lower the number, the lower the health risk.
Avoid bottles marked with the numbers 3, 7, or 10, as they typically indicate the presence of bisphenol A (BPA).
On the other hand, bottles with the numbers 1, 2, 4, or 5 are considered safer, as they’re free from expanded polystyrene, phthalates, and BPA.
Recommendations
- Avoid drinking water from a bottle that’s been left in a hot car for more than 3 days, especially if it’s been exposed to sunlight.
- Don’t reuse the same plastic bottle more than 3 times, even if you’ve washed it thoroughly.
- The safest and most reliable option is to use glass bottles, which you can refill with any kind of liquid.
Another useful tip: Never freeze plastic bottles.
Freezing them could cause the plastic to release carcinogenic dioxins into the water. This was confirmed by researchers from the Johns Hopkins Bloomberg School of Public Health.
By making smarter choices about the containers we use, we can reduce health risks without giving up convenience.
