Importance of Staying Hydrated
Everyone knows that it is essential to provide moisture – water delivers nutrients to cells, regulates body temperature, lubricates joints, and deprives waste. You can’t live without it. By wearing a reusable water bottle, a consistent fluid supply is ensured throughout the day. However, concerns about the environmental and health effects of these containers have been expressed.
The Surprising Truth About Glass Bottles
An astonishing new study showed that some glass bottles release significantly more microplastics than plastic bottles, especially when the glass bottles have lacquered logos or metal caps. This is a surprising finding for everyone who has opted for glass, assuming it is the cleanest option.
Types of Water Bottles and Their Risks
There are several types of water bottles available, each with its own set of risks. The following sections outline the pros and cons of each type.
Plastic Bottles
Plastic bottles deserve their bad reputation, as studies have found that they can leach chemicals and microplastics into the water they contain. Microplastics can damage reproductive, digestive, and respiratory health. Most disposable plastic water bottles consist of PET (polyethylene terephthalate), which can exhaust toxic heavy metals like antimony, especially if exposed to high temperatures or squeezed.
Glass Bottles
If you use glass, you should choose simple, unpainted bottles with plastic caps (not metal) and avoid etched logos or decorative coatings. Store the glass bottle upright to reduce contact between the liquid and the cap. A study published last month found that decorative colors on the caps, particularly the inner feed, can flake off due to friction and abrasion, contaminating the liquid.
Aluminum Bottles and Cans
There are also problems with aluminum bottles and cans, as they are almost always lined with BPA-based resins that can deteriorate over time or with acid. These containers should not be reused, stored in heat, or filled with acidic drinks like lemon water or sparkling drinks.
Carton Water
Carton water, such as boxed water or Just Water, is typically lined with BPA-free plastic and foil. While they are marketed as environmentally friendly, they are not free from microplastic exposure and should not be reused or heated.
Stainless Steel Bottles
Stainless steel is the best option if done correctly. Stainless steel is generally regarded as non-toxic and resistant to bacterial growth, but many popular stainless steel cups have BPA-free plastic lids or straws that can exhaust microplastics if exposed to hot water, acidic liquids, or high temperatures in the dishwasher.
Reducing Microplastic Exposure
An easy way to reduce microplastic exposure is to use a reverse osmosis filter on your water before filling your bottle. For acidic liquids like lemon water or drinks with apple cider vinegar, the safest options are not made of stainless steel and simple borosilicate glass. If a lid or straw is needed, silicone is generally the best bet.
Caring for Your Water Bottle
All efforts to select the right water bottle will be wasted if it is not properly maintained. To keep your water bottle clean and safe, follow these tips:
- Wash your water bottle daily, removing the bottle and cleaning each part separately, especially the lid and straw.
- Use soap and water that is less than 120 degrees Fahrenheit to clean the bottle.
- Replace reusable plastic bottles every three to six months or earlier if you notice any signs of degradation.
- Glass and stainless steel bottles can last much longer with good care, but check plastic lids and straws and replace them regularly, especially if they are worn out or damaged.
