How to protect your family with a healthy car? Do the experts of China automobile health index have any suggestions?

When it is cold, friends in the north rely on heating, while friends in the south basically rely on shaking. However, as soon as you get on the bus, people in the north and south are the same: once you close the window and turn on the air conditioner, it is warm all the way. In order to keep warm, many people seldom open the window for ventilation when driving. For children and the elderly whose immunity is far lower than that of adults, this is not a good practice for the health of passengers.

China automobile health index experts said: A closed environment without air convection will become a hotbed of bacteria and viruses, and there are many microorganisms closely related to infectious pathogenic microorganisms in the car, including Legionella, Mycobacterium tuberculosis, atypical pneumonia virus, avian influenza virus, mycoplasma and chlamydia.

In the face of the flu, how should we use cars healthily to protect ourselves and our families?

First, the old steps: ventilation while driving.

Some netizens said that since the flu is raging, doesn't ventilation let the virus enter the car? This reminds Bian Xiao of similar remarks made during the epidemic earlier this year. The netizen asked the medical expert: If the window is ventilated at home, will the virus outside come in? Medical experts gave the answer with a vivid metaphor: the virus is like a bottle of ink, and our whole living environment is like the sea. No matter how black the ink is, pouring it into the sea will not change the color of the sea.

In the same way, ventilation is actually to exchange the dirty air generated in a relatively closed home with the outside air, and release the virus in the home to the outside world, and the outside virus will be diluted in the air, reducing the threat to people. Compared with home, the space inside the car is smaller, and viruses multiply rapidly in a warm environment. The virus concentration inside the car is definitely much higher than that outside (even if there is no virus, there are naturally emitted volatile organic compounds (VOC) and carbon dioxide continuously exhaled by passengers inside the car. ), so ventilation is more "cost-effective".

The second is to keep the car clean and avoid excessive cleaning.

Everyone is too lazy to move when it is cold, but the cleaning frequency in the car should not be reduced. In addition to the flu, autumn and winter are also the high season of smog and sand blowing, and the load of on-board air conditioners and filters increases instead of decreasing. To keep the car "mask" clean, it is necessary to regularly check and replace the air filter and clean the air conditioning pipeline (in general, the air filter replacement cycle is 10000 km). Some drivers will use car air purifier, so it is best to remove the filter screens of these small air purifiers every other month for thorough cleaning to avoid bacterial growth.

After using the car every day, you can clean and disinfect the parts that you often contact in the car, such as door handles, seats, center console, etc. To prevent the virus from staying inside. However, there is no need to spray disinfectant repeatedly in the car. This excessive disinfection behavior not only makes the accessories in the car easy to corrode, but also may cause greater health risks if the occupants in the car inhale or come into contact with disinfectant.

Then we should develop good car habits with our families.

For example, if you try not to eat or drink in the car, it is not only easy to eat bacteria, but also the residue left in the car and spilled drinks will breed more bacteria. Try to avoid taking other people's vehicles for yourself and your family; Teach children to wash their hands in time after taking public transport, and you can also prepare some hand, foot and mouth cleaning products in the bags of children and the elderly. If there are passengers with a cold or illness in the car, everyone in the car should wear a mask. The practical significance of mask to prevent infection need not be repeated, which can protect both yourself and your family.
