Why You Should Never Drink Water from a Warm Plastic Bottle

Staying hydrated is essential for everyone, regardless of whether you're an athlete or someone who leads a more sedentary lifestyle. The general guideline is to drink roughly half your body weight in ounces every day. If you're already meeting that target, you might assume you're set. However, there's more to consider—like the container you're using to drink your water. While a disposable plastic bottle may seem convenient, it's not only bad for the planet but also for your health and your wallet. But here’s something even worse: drinking water from a warm plastic bottle.

Today, Office H2O wants to shed light on why you should steer clear of drinking from a warm plastic bottle. Although consuming water from a single warm plastic bottle might not immediately harm you, experts are warning that regularly doing so could lead to bigger issues down the line. So why should you avoid drinking from a warm plastic bottle? Let’s dive into the details.

The Risks of Sipping from a Warm Plastic Bottle

A recent piece from National Geographic highlights the dangers of reaching for a warm plastic bottle to quench your thirst, particularly during the summer. Rolf Halden, director of the Center for Environmental Health Engineering at Arizona State University’s Biodesign Institute, cautions against this habit, stating, “The higher the temperature, the more the chemicals in plastic can seep into food or drinking water.”

Plastic water bottles are typically made from polyethylene terephthalate (PET). When these bottles are exposed to heat, they release chemicals like bisphenol A (BPA) and antimony. Studies suggest that BPA can lead to adverse health effects, especially in children. Furthermore, antimony is classified as a carcinogen by the International Agency for Research on Cancer, which is part of the World Health Organization.

In a study led by University of Florida soil and water science professor Lena Ma, researchers examined the chemical changes in 16 different water brands after keeping them at 158 degrees Fahrenheit for four weeks. Their findings revealed a concerning “worst-case scenario” for human consumption. Over the four-week period, antimony and BPA levels rose significantly. Based on these results, Ma advises against leaving bottled water in a hot garage or car during scorching summer days.

The Impact of BPA and Antimony on Human Health

Both BPA and antimony have been associated with various health problems. BPA, for instance, has been linked to reproductive, immune, and nervous system issues. It has also been tied to an increased risk of Alzheimer’s, metabolic disorders, childhood asthma, heart disease, and type 2 diabetes. Research indicates that BPA can even negatively influence children's behavior.

What about antimony? According to the Environmental Protection Agency (EPA), people are exposed to low levels of antimony naturally. Short-term inhalation exposure can irritate the eyes and skin, while long-term exposure has been connected to respiratory, cardiovascular, and reproductive problems. Although antimony isn't classified as a carcinogen by the EPA, studies have shown that it can promote lung tumor growth in rats when inhaled.

How Often Is Too Often?

Now, how concerned should you be about drinking from a warm plastic bottle? It largely depends on how frequently you do it. Overall, the trace amounts of chemicals consumed from a single warm bottle aren't likely to result in severe health issues. However, experts emphasize that regular exposure increases the risks.

Halden explains, “Drinking from one PET bottle probably won’t harm you. But if you’re consuming from 20 bottles a day, the safety concerns change dramatically.”

The cumulative effect of being surrounded by plastics or microplastics in our water poses the greatest threat to our health. For this reason, Halden and many others recommend switching to a metal water bottle instead of using disposable or reusable plastic ones, especially in warmer conditions. Additionally, while not part of her initial study, Ma encourages using tap water, which is regulated by the EPA, over bottled water.

Say Goodbye to Plastic Bottles with Office H2O!

The research outlined in this article underscores the importance of avoiding warm plastic bottles whenever possible. Moreover, given the environmental and financial toll of plastic bottles, it’s clear that minimizing their use altogether is the best course of action. Luckily, Office H2O offers a simple solution: a bottleless water system. These systems utilize advanced filtration and purification technologies to provide clean, safe drinking water without the need for single-use plastic bottles.
