Things You Should NEVER Leave in Your Car in Summer

As summer temperatures soar across Pakistan, car owners face a unique set of challenges when it comes to protecting their vehicles—and everything inside them. The inside of a parked car can reach dangerous temperatures in minutes, turning everyday items into potential hazards. Whether heading to work, the beach, or running errands, knowing the Things You Should NEVER Leave in Your Car Summer can save you from expensive damage, health risks, and safety concerns.

In this article, we’ll discuss certain items that should never be left behind, what kinds of damage extra heat can cause, and how to take simple steps to keep your car—and its contents—safe.

The Science Behind Car Heat Buildup

Before diving into the specific items, it helps to understand how hot your car can get. In summer, even on a seemingly mild 30°C day, the interior of a closed car can climb to over 50°C within 20 minutes: dark interiors, metal surfaces, and direct sunlight speed up the heat trap.

Now imagine the impact heat level can have on delicate, pressurized, or electronic items.

1. Electronics (Phones, Tablets, Laptops)

Gadgets are sensitive to heat—and cars in summer can become heat chambers. Leaving your smartphone, tablet, or laptop inside a hot car can:

• Damage to internal batteries and circuits
• Cause screen warping or cracks
• Lead to data loss due to overheating

Always take your devices with you or store them in a shaded, ventilated spot if necessary.

2. Aerosol Cans (Deodorant, Air Fresheners, Paint)

Aerosol cans can explode in high heat. These containers are pressurized, and excessive warmth can cause them to rupture—posing a fire risk and damaging your vehicle’s interior. Never leave such products in the glove compartment or dashboard area.

3. Plastic Bottles and Food Containers

You might think a half-empty water bottle is harmless, but it’s a ticking time bomb. When exposed to direct sunlight, plastic can release harmful chemicals like BPA into the water. Additionally:

• Food left in the car spoils quickly
• Melted packaging can ruin seats and upholstery
• Bad smells can linger for weeks

Instead, carry reusable stainless steel bottles and avoid leaving any snacks behind.

4. Medication

Many medications have specific storage temperature guidelines. Heat can reduce their effectiveness or even render them dangerous. This includes:

• Insulin
• Antibiotics
• Inhalers
• Painkillers

Store medicines in a cool, dry place and never leave them in the car during the day.

5. Batteries and Power Banks

Lithium-ion batteries (used in power banks and other electronics) can swell, leak, or even explode in extreme heat. Is that spare battery or portable charger in your glove box? It’s better off with you.

6. Makeup and Cosmetics

Under heat, makeup melts, clumps, and separates, making it unusable. Lipsticks, foundations, and creams can also leak, causing messy spills on seats and carpets. Keep your cosmetic bag out of the heat for your wallet and your car’s cleanliness.

7. Sunglasses and Glass Items

Oddly enough, some people leave their sunglasses on the dashboard. Not only can the plastic frames warp, but if they’re made of glass, they might crack or even magnify sunlight and damage dashboard surfaces. Store them in your console or glove box if shaded.

8. Pets and Children – NEVER Leave Them Behind

This one goes without saying, but it’s the most important. Pets and children are at extreme risk in a hot car. Even a few minutes can lead to heat stroke or death. If you need to leave the vehicle, take them with you.

9. Credit Cards and ID Cards

Heat can warp cards or demagnetize the strip, leaving you with unusable payment methods when needed. If you’re stepping out, take your wallet and essentials with you.

Smart Tips to Keep Your Car Cool

While it’s best to avoid leaving sensitive items in the car during summer, sometimes it’s unavoidable. Here are a few car care accessories that can help reduce heat buildup and protect your vehicle’s interior:

1. Use Car Tints

Installing car tints can significantly block out UV rays, reduce glare, and keep your car cooler—even when parked in the sun.

2. Invest in Sun Shades

Car sun shades for the windshield and rear windows reflect sunlight and can lower the cabin temperature by several degrees.

3. Window Vent Visors

Allow safe air circulation without exposing the interior to rain or dust.

4. Park in the Shade or Use a Car Cover

Choose shaded areas or use a breathable car cover to limit heat exposure whenever possible.

5. Crack the Windows (When Safe)

Leaving windows slightly open (if secure) allows hot air to escape and reduces the internal temperature.

Build a Car-Safe Routine

Here’s how you can prevent damage and enhance summer safety:

• Do a quick car sweep before locking up—remove electronics, food, and personal items
• Store essential car items in insulated bags or under seats where it’s cooler
• Use dashboard organizers or storage compartments to shield heat-sensitive items
