Can water left in a hot car still be drunk?

[OPaige]

Unopened water left in a hot car can still be drunk, but opened water should not be consumed. The reasons are as follows: 1. Most bottled water on the market has a PE1 label. This material generally begins to change at around 80 degrees Celsius, and decomposition requires temperatures as high as 120 degrees Celsius. Clearly, even when left in a car, where temperatures can get very high, they are unlikely to reach this level. Therefore, as long as the bottled water is produced by a reputable manufacturer, there is no need to worry about it posing any health risks; 2. If the water has been opened, it is not recommended to drink it. This is because when drinking bottled water, various bacteria can enter the bottle. In the high temperatures inside a car, these bacteria can multiply rapidly in the water.
