A quick stop at the bakery, a fast dash into the pharmacy, groceries still in the trunk: In summer, a car quickly becomes a heat trap. What feels harmless in everyday life can become dangerous for children and animals and also unnecessarily compromise food.

The most important rule is simple: When the car is parked, no one waits inside. Children, pets, and perishable groceries come along or are taken home immediately.

Why the car is not a waiting room

In a parked car, heat builds up rapidly. A shady spot, slightly opened windows, or a sunshade on the windshield are not reliable protection. Furthermore: Children cannot regulate heat as well as adults, animals cannot simply get out, and refrigerated goods quickly lose their safety in a heated car.

Especially on days with high temperatures, a little plan before the trip is worthwhile: first run errands without refrigerated goods, then buy groceries, and finally head straight home.

Children: everyone out once, everyone out

Even if a child is sleeping or the trip seems short: Children should not be left alone in the car in summer. This also applies in the morning when it doesn't feel extremely hot outside yet. Inside the vehicle, it's not just the outside temperature that counts, but also solar radiation, how long the car has been standing, and air circulation.

  • Do not make short exceptions: Bakery, ATM, gas station, or pickup station often take longer than expected.
  • Consciously check the back seat: Look back once before locking up, even if everyday life is hectic.
  • Keep children's items visible: Keep the diaper bag, water bottle, or kindergarten backpack within reach in the front so the back seat doesn't slip out of sight.
  • Clearly coordinate carpools: Who is taking which child, who gets out where, who checks at the end?

Pets: A quick errand is too long

For dogs and other pets, a parked car in the heat is not a safe place to stay. Water in a bowl or a crack in the window does not reliably solve the problem. If animals are traveling with you, it should be clear beforehand that they are allowed to come along at the destination or that someone stays with them without leaving the car in the sun.

For errands, it is usually better to leave pets at home in a cool room. This saves stress and prevents a short stop from becoming an emergency.

Food: Buy refrigerated goods last

Groceries don't like a hot car either. Raw meat, fish, dairy products, whipped cream, ready-made salads, desserts, frozen goods, and dishes containing egg are particularly sensitive. Anyone shopping in summer should keep the cold chain interruption as short as possible.

  • Take a cooler or insulated bag with you: Insert ice packs at home and don't buy them at the store.
  • Sort your route: Run errands at the drugstore, post office, and other places before buying groceries.
  • Put refrigerated goods in the cart last: Pick up frozen products and fresh items at the very end.
  • Drive straight home: No second round through town if perishable goods are in the trunk.
  • Put away immediately at home: Fridge and freezer first, dry supplies afterwards.

What should not be left in the car in summer

Besides children, animals, and food, there are a few things that are better not left in the car permanently in the heat:

  • Medication: Many preparations should not be stored in warm conditions. When in doubt, check the package insert or ask at the pharmacy.
  • Sunscreen and cosmetics: Heat can affect consistency and shelf life. Better to take them with you in your bag.
  • Water bottles: Water for on the go is good, but don't leave bottles in the blazing sun for days.
  • Batteries and spray cans: Observe manufacturer instructions and do not store unnecessarily in a hot interior.

The exit check before locking up

A short routine helps ensure nothing is overlooked:

  1. Engine off, take handbag or mobile phone.
  2. Check the back seat.
  3. Check the footwell.
  4. Open the trunk, take refrigerated goods and bags with you.
  5. Lock the car and only then walk away.

This sounds trivial, but that is exactly why it is effective: Routine protects against mistakes when it is hot, busy, and hectic.

If you see a child or animal in a hot car

Stay nearby, speak to other people, and try to locate the vehicle owner quickly. If a child or animal is visibly in distress or help is not arriving quickly, call emergency services immediately. It is important not to argue for long, but to describe the situation clearly: location, vehicle, license plate, who is in the car, and what their condition appears to be.
