Heat stroke is not a myth, so avoid getting into an overheated car, especially if you don’t have air conditioning.
You can quickly lower the temperature in a car parked in the sun by up to 10 degrees with a simple trick. Lower the passenger side window and close the door, and then close and open the driver's door with quick movements several times.
To make driving more comfortable, be sure to cover the leather seats with some cotton material, and protect the steering wheel. If you do not cover the steering wheel, at least turn it to the side when parking. So when you start the car and return it to the starting position, the part where your palms are will be cold.
Cars heat up quickly in high heat even if they are parked in the shade, and in just 10 minutes the internal temperature can rise by as much as 20 degrees. Not even a slightly lowered window helps keep the car from overheating, so never leave children and pets in the car, even for a few minutes.
In high heat, the temperature in the car can rise to 50 degrees in just a few minutes, and children are especially sensitive because their body temperature rises three to five times faster than in adults due to still underdeveloped body thermoregulation.
Be careful with leaving groceries in the car as well. Rather, take them home in the fridge before stopping for a drink in a local bar as high temperatures are conducive to the growth of bacteria. Minced meat and ready-cooked food are especially sensitive.
Fresh milk must also be in your refrigerator within an hour, as well as cured meat products. If you already have to leave groceries in the car, be sure to park in the shade and leave them on the back seat, never in the trunk. If you plan to stay outside for a long time after shopping, bring a portable refrigerator for the most sensitive foods.
