Avoiding alcohol consumption in vehicles is a smart decision for safety reasons. It's preferable to stick with beverages in a stationary setting.
In the sweltering heat of summer, it's essential to be mindful of the items we leave in our cars, particularly drinks. A hot car can transform everyday objects into potential fire hazards and pose health risks, particularly when it comes to plastic bottled drinks.
The primary concern is the heat-induced chemical leaching from plastic containers. When plastic bottles, especially those made of certain plastics containing BPA (bisphenol A), phthalates, or antimony, are exposed to high temperatures, these chemicals can leach into the liquid inside. These substances are known hormone disruptors and have been linked to various health issues such as hormonal disorders, cancer, or diabetes in studies [1][2].
Heat causes chemicals like BPA or phthalates to migrate from the plastic into the drink, posing potential risks to cellular and hormonal health over time. A one-time exposure is unlikely to cause immediate harm, but habitual consumption of such contaminated drinks could be detrimental [1].
For carbonated drinks like sodas, heat increases internal pressure due to carbonation, which can cause cans to deform, spray, or in rare cases, even explode if the seal weakens. However, such explosions are uncommon [2].
To minimize these risks, it is advisable not to leave plastic bottled drinks in hot cars for extended periods. If you must, avoid making a habit of drinking from bottles that have been exposed to high heat, and prefer alternatives like insulated containers or glass bottles where feasible [1][2].
Moreover, it's advisable to only travel with necessary documents and get a cool-down at rest areas to avoid exposing sensitive items to high temperatures. Electronic devices like smartphones, power banks, or e-readers overheat and there is a risk of fire when exposed to high temperatures in a car. Sunlight bundled with water and plastic in a bottle can cause upholstery and carpet to glow, as documented by US fire departments. Medicines and cosmetics lose their effectiveness or release harmful vapors when exposed to direct sunlight [1][2].
In conclusion, the main health risk is the leaching of harmful chemicals from plastic into drinks when left in a hot car, with additional concerns about pressure build-up in carbonated beverages. By taking simple precautions, such as avoiding leaving plastic bottles in a hot car and choosing alternative containers, we can help ensure a safer and healthier summer driving experience.

Heat-induced chemical leaching from plastic containers, such as BPA (bisphenol A), phthalates, or antimony, can pose potential health risks when left in a hot car for extended periods. To promote a healthier lifestyle and sustainable living, it's wise to avoid leaving plastic bottled drinks in your vehicle and opt for insulated containers or glass bottles where feasible.
