Life can be a whirlwind, and it’s all too easy to let your car become a temporary storage unit. But while it may seem convenient to leave certain items in your vehicle, doing so can put your belongings, and even your safety, at risk. Here’s a closer look at why some items should never be left inside your car, and the consequences of doing so.

1. **Electronics**: Keeping your electronics in the car might seem practical, but it opens the door to theft. The temperature extremes that often occur inside vehicles can also harm your devices. Electronics are not only expensive but often contain important personal information, making them a prime target for thieves. Protect your gadgets by taking them with you whenever you leave your vehicle.

2. **Water Bottles**: On a hot day, you might think a water bottle is safe in your car. However, high temperatures can cause harmful chemicals like bisphenol A (BPA) to leach into the water. BPA exposure has been linked to various health issues, including diabetes and cardiovascular disease. It’s always best to drink fresh water from a newly purchased bottle.

3. **Medication**: Just like electronics, medications are sensitive to temperature fluctuations. Most medicines should be kept at a stable temperature between 59 and 77 degrees Fahrenheit. When left in a hot or freezing car, medications can lose their effectiveness, putting your health at risk. Always store medications in a cool, dry place to maintain their potency.

4. **Purse or Wallet**: Leaving your purse or wallet in the car, even if hidden, can attract thieves. A thief can gain access to not only your cash and credit cards but also personal information like your driver’s license. It’s wise to take your purse with you, reducing the risk of theft and identity fraud.

5. **Important Documents**: Sensitive documents such as tax forms, financial statements, or your passport should never be left in your car. If a thief gets their hands on these papers, they could commit fraud or identity theft. Always keep vital documents safe and secure, preferably in your possession.

6. **Wine**: For wine enthusiasts, it’s crucial to store wine at the right temperature and humidity. Leaving a bottle of wine in a hot car can ruin its flavor and quality. Moreover, high temperatures can expand the air inside the bottle, pushing the cork out and potentially contaminating the wine. If you’re transporting wine, aim to keep it in a temperature-controlled environment.

7. **Canned Beverages**: Extreme cold and heat can cause canned beverages to explode. Imagine the sticky aftermath of cleaning up a soda explosion in your car—it’s a mess you won’t want to deal with. To avoid this disaster, always keep your canned drinks out of your car until you’re ready to enjoy them.

8. **Pets**: This one is a no-brainer, but it bears repeating: never leave your pet alone in a parked car. Temperatures can skyrocket, often exceeding 115 degrees Fahrenheit on hot days. This can lead to severe health complications or even death for your beloved furry friend. Always bring your pets with you or ensure they are safely at home.

9. **Groceries**: Leaving groceries, especially perishables like dairy and meat, in a hot car is a recipe for disaster. The USDA advises that refrigerated foods shouldn’t be left out for more than two hours—one hour if the temperature exceeds 90 degrees Fahrenheit. Leaving food in a hot car invites harmful bacteria to thrive, which can lead to foodborne illnesses. Always prioritize food safety by taking your groceries straight home after shopping.

10. **Aerosol Cans**: Leaving aerosol cans in your car can be dangerous. Pressurized cans can explode at temperatures above 120 degrees Fahrenheit, and it’s easy for cars to reach such temperatures during the summer. The explosion not only risks damage to your vehicle but could also cause injuries. Keep aerosol products in a safe location, away from excessive heat.

11. **Lighters**: Similar to aerosol cans, lighters can also cause potential hazards when left in hot cars. They can leak or explode under high temperatures, possibly igniting a fire. Always store lighters in a safe and cool location.

12. **Plants**: While plants can brighten up your car, leaving them inside for too long can lead to dehydration and stress due to fluctuating temperatures. In extreme heat or cold, even hardy plants can suffer or die. If you adore having plants, ensure they’re cared for properly outside of your vehicle.

13. **Art Supplies**: Parents know the struggle of melted crayons. Art supplies are sensitive to heat, which can cause them to melt and create a colorful mess. Avoid leaving art supplies in your car to keep your vehicle tidy and your supplies intact.

14. **Cosmetics**: Your makeup deserves better than a hot car. Leaving cosmetics, like lipstick or mascara, in a heated vehicle can result in melting or freezing, rendering them unusable. To keep your makeup in perfect condition, take it with you whenever you leave the car.

15. **Cash**: Even a small amount of cash left visible in your car can attract thieves. Don’t tempt fate! Always take your money and valuables with you to ensure they remain safe and secure.

16. **Musical Instruments**: If you’re a musician, you know how essential it is to keep your instruments in prime condition. Leaving wooden instruments like guitars or violins in your car can lead to irreversible damage. Extreme temperature changes and humidity levels can cause the wood to warp, crack, or split, ruining the sound quality and playability of your beloved instruments. Always bring them inside when not in use to ensure their longevity.

17. **Glasses**: Did you know that the frames of your glasses and sunglasses can be affected by the temperatures inside your car? Heat can warp plastic frames, while freezing temperatures can make them brittle, increasing the risk of breakage. To keep your eyewear safe and in good condition, it’s best to take them with you whenever you leave the car.

18. **Sunscreen**: Having sunscreen handy is important, especially during sunny days. However, keeping it in a hot car can reduce its effectiveness. The heat can break down the protective chemicals, making it less reliable when you really need it. Instead, carry it with you to ensure you have effective sun protection whenever you head outdoors.

19. **Batteries**: Batteries are sensitive to temperature fluctuations, and leaving them in your car can lead to leakage or reduced energy capacity. High heat can cause sealed batteries to leak, while low temperatures can diminish their performance. For optimal battery life and safety, store them in climate-controlled environments.
