We all know the importance of staying hydrated, especially during Texas's hot summer months. Usually, we put a water bottle in our car and assume that we will pick it up when we get out of the car. But what happens when we accidentally leave them in a hot car? Is it safe to take a sip from a bottle that's been sitting in the sun for hours? Let's fill up our bottles and take a closer look at the dilemma of the water bottle left in the car.

What are plastic water bottles made from?

Most plastic water bottles are made from a type of plastic called polyethylene terephthalate, or PET for short. This material is popular for its durability and transparency, and flexibility. Compared to other plastics, it has a relatively low melting point. This quality allows it to be reshaped multiple times without undergoing a chemical change. This leads us to why it's an issue to leave in a hot car.

What happens as temperatures rise?

As the heat intensifies, the plastic's chemical bonds start to break down, which can lead to harmful chemicals seeping into the water. In a 2014 study, researchers exposed plastic water bottles to high temperatures for four weeks and found that dangerous chemicals like antimony and bisphenol A (BPA) had leached into the water. So, it's worth paying attention to the type of bottle you're using and being cautious during hot weather to ensure that the water you're drinking is clean and safe.

We often overlook the possibility of bacteria as a hazard. The water in our bottles is pure and sanitary when it leaves the bottling plant. However, when we open and drink from it, it can become contaminated with bacteria. This is why leaving a water bottle in a hot car can be problematic, as the heat can promote bacteria growth.

Speaking of temperatures rising.

Water bottles can also be a fire hazard. Thats right! According to fire safety experts, plastic water bottles left in direct sunlight or near heat sources have been known to act as magnifying glass, focusing the sun's rays and creating a fire hazard. While rare, this is a risk that can easily be mitigated by simply keeping your water bottles out of direct sunlight and away from heat sources.

But is it safe to drink from a water bottle that has been sitting in a hot car?

If you must drink from a water bottle left in a hot car all day, it probably won't make you seriously ill, unless someone else has already drunk from it. In that case, bacteria could be growing in it, and it becomes a different matter.

Just a note: it's not the water itself that expires, rather it's the container it's stored in that can become problematic. When traveling, there are other options available besides plastic water bottles to help you stay hydrated. Reusable canteens and insulated tumblers are great options that keep your water cool and prevent the risk of these hazards.

It's clear to see that when it comes to storing water in warm environments, caution should be taken. With a few simple tips and tricks, you can help ensure that the water you drink is safe and clean. Now - stay hydrated!
