Staying hydrated is a must—but have you ever wondered if the water stored in your plastic bottle is still safe to drink?

As convenient as reusable bottles are, concerns about plastic degradation and potential chemical leaching have become increasingly common, especially when bottles are left in hot environments or reused over long periods.
Most plastic bottles are made from materials like polyethylene terephthalate (PET) or polycarbonate, which are generally considered food-safe under normal use. However, when exposed to heat, UV light, or long-term wear, some plastics can release trace amounts of chemicals such as bisphenol A (BPA) or microplastics into the water. These substances may affect taste and could pose health concerns over time.

Even BPA-free bottles are not immune. Research shows that certain alternative compounds used in BPA-free plastics may still behave similarly under stress. Signs of wear like scratches, cloudiness, or warping may indicate that it is time to replace your bottle.
For those seeking a safer and more durable solution, stainless steel and borosilicate glass bottles are increasingly popular. These materials are non-reactive, free from harmful chemicals, and retain water quality even under heat or repeated use. They are also easier to clean thoroughly, making them a more hygienic option for everyday hydration.

Ultimately, while occasional use of plastic bottles is unlikely to cause harm, switching to more stable materials offers peace of mind and long-term value.
Key Details:
Plastic bottles may leach chemicals when exposed to heat or wear
BPA-free does not always mean chemical-free under stress
Look for signs of wear: scratches, discolouration, or odour
Safer alternatives: stainless steel or borosilicate glass
These options are non-toxic, heat-resistant, and reusable
