Is it safe to drink water left in the car?
2 Answers
Yes, it is safe. The plastic bottles used for water are relatively stable. Under normal circumstances and at typical temperatures, substances in plastic bottles are unlikely to decompose. Therefore, bottled water within its expiration date can still be safely consumed even if it has been exposed to high temperatures in a car. Additional information: The claim that heated plastic water bottles release toxic substances is not entirely accurate, as car temperatures rarely exceed 100 degrees Celsius, so there's no need for excessive concern. However, it's advisable to minimize consumption of water that has been exposed to prolonged sunlight. Especially for opened bottled water, it's best to consume it within 24 hours. If it has been more than 24 hours, there's a higher risk of bacterial contamination, which could affect your health.
During scorching summer days, I've often grabbed a plastic water bottle from my car and taken a sweltering sip without a second thought – done it multiple times. Later, after researching, I realized the risks: plastic bottles, especially common PET mineral water bottles, readily release harmful substances in high heat. When parked under blazing sun, a car's windshield can turn into an oven, pushing temperatures above 70°C. Left for just 2-3 hours in such conditions, plasticizers and antimony from the bottle can leach into the water. The most practical solution? Switch to a stainless steel flask or glass bottle for worry-free car storage. If desperately thirsty, avoid bottles that feel hot to the touch – popping into a convenience store for a fresh one is far safer.
