A video circulating on social media warns of the risks of leaving objects inside the car at high temperatures. The publication lists items such as lighters, perfumes, glasses and aerosols as potential causes of fires or explosions. However, although some risks are real, some of the information requires contextualization.
Inside closed vehicles exposed to the sun, the temperature can easily exceed 60°C and, in some cases, reach close to 70°C. This environment favors the expansion of gases and the degradation of materials, which can pose a danger, especially with flammable items.
Among the objects mentioned, the lighter is, in fact, one of the most dangerous. Because it contains gas under pressure, it can rupture or even explode in extreme heat conditions. Aerosols, such as deodorants and sprays, also pose a similar risk, as they accumulate internal pressure and are highly flammable.
In the case of perfumes, the risk exists, but it is smaller. Because it contains alcohol, the liquid is flammable, but it is unlikely to spontaneously combust without an ignition source. Still, heat can damage the bottle and change the composition of the product.

Glasses, often cited as capable of causing fires due to the magnifying glass effect, rarely cause fires in practice. For this to happen, a very specific alignment with sunlight and highly flammable material would be required, which makes the risk considered low by experts.
The water bottle can, in specific situations, act as a lens and concentrate light, but this is also a rare event. The biggest danger, according to traffic experts, is when the object moves and interferes with driving, potentially blocking the pedals during braking.
Despite some exaggerations, the general warning is valid. Avoiding leaving objects inside the car, especially on hot days, is a simple measure that reduces risks and preserves both the safety and durability of the items.
Authorities recommend that drivers keep the vehicle ventilated whenever possible and not store flammable products inside the car.
