Sitting in a car regularly exposed to the sun can lead to cancer.

A study reported shocking figures that leaving your car in the sun at just 35 degrees Celsius for 40 minutes is enough to turn your car into a “bread oven” with a temperature of 70 degrees Celsius.

In particular, the longer your car is exposed to the sun, the faster its temperature will increase. This not only seriously affects your car but also affects the health of the people in the car.

Specifically, under the influence of weather conditions, many parts of the car can be degraded, easily becoming harmful to the health of the owner. When the temperature increases, some materials in the car's interior compartment such as rubber and vinyl will begin to evaporate, while the oil and solvent inside the material will vaporize.

They will form a film on the car windows and you can easily notice when the sun shines on them. The film and the smell that evaporates in the car will not cause immediate harm, but if exposed for a long time, people may have some respiratory problems and lead to cancer.

Also according to research by American scientists, when the temperature inside the car reaches 50 degrees Celsius, it will evaporate toxic substances and this phenomenon has the scientific name heatstroke or hyperthermia. Or more simply, this phenomenon is similar to the "greenhouse" effect that you often hear about in the media.

Besides, the unpredictable harm of having to sit at work or work in hot environments for men also affects reproductive health.

According to obstetrician and gynecologist Le Thi Minh Chau, men who bathe in water that is too hot, sit in a hot car seat, wear tight pants, sit for long hours at the office, smoke, drink alcohol, work in an environment exposed to many chemicals, drive long distances, etc. can affect their reproductive health and easily become infertile.

For children, sitting in a car exposed to the hot sun has caused many unfortunate consequences. In the US, from January to May 2018, 6 children died in cars. Every year, an average of 37 children die for this reason. The cause comes from the indifference and forgetfulness of adults.

Research from two American universities, Arizona State University and the University of California at San Diego School of Medicine, shows that the heat from cars parked in the sun can seriously affect human health, even causing death. The research by these two universities focuses on the harmful effects on children under 2 years old - the group most likely to be "forgotten" in cars.

In reality, many parents think that just leaving their children in the car, going to the supermarket to do some quick shopping and then going out right away will be fine. However, within 30 minutes to 1 hour, under the heat from above and the road surface, the car becomes a mini "greenhouse", causing heat shock to children or pets in the car. In the car, the child's body temperature rises to 40 degrees Celsius and cannot cool down, causing hyperthermia.
