Drinking bottled water left in your car may not be as safe as you think. Here are 7 reasons why.

Heat can cause plastic bottles to leach harmful chemicals like BPA into your water.

Warm temperatures create ideal conditions for bacteria, especially in opened plastic bottles.

Heat exposure alters water’s taste, making it unappealing and hard to drink.

If stored for a long time, certain bacteria or algae may grow, especially in non-purified water.

If the water is contaminated or tastes bad, you might drink less and risk dehydration.

Studies indicate that heated plastic may leach carcinogens, increasing cancer risk.

Reusing bottles in heat weakens plastic, making it prone to releasing harmful substances.
