Four unsuitable driving in summer

1. Don't wear sunglasses that are too dark and too big and heavy
According to research, the dark colors of sunglasses can delay the time for the eyes to send the image to the brain. This visual delay also causes distortion of the speed perception, making drivers wearing sunglasses make wrong judgments, especially cars and motorcycles moving at 80 kilometers per hour. At this time, too deep sunglasses will extend the driver's reaction time to the situation by 100 milliseconds, resulting in an increase of 2.2 meters in the emergency braking distance.

Second, overeating cold drinks
The weather is hot in summer, the driver sweats more, and often feels upset and thirsty. Therefore, when some companies have opportunities for cold food and drink, they will overeat and eat, which is not good for the body. Because when the driver is driving, most of the blood will flow into the muscles that are tense and active to supply enough nutrients and carry away the waste, which temporarily reduces the gastrointestinal blood supply. At this time, if a large amount of cold drinks such as ice cream is consumed, it will cause the gastrointestinal tract blood vessels to contract suddenly, reduce blood flow, often cause physiological dysfunction, affect the body's digestion of food, and may also cause stomach pain, diarrhea and other digestive tracts disease.

3. The air conditioner should not be used for a long time
Generally, vehicles equipped with air conditioners have better sealing performance. When the air conditioner is working, the replacement of the air in the car is 2 to 5 times more than normal, and some even 8 times. The vast majority of people will feel dizzy and tired when they stay in this environment for a few hours, and their memory will diminish. If the vehicle is not running and the air conditioner is used, the risk is greater. This is because when the air conditioner is working, the carbon monoxide gas emitted by the engine is sucked into the car. At the same time, the people in the car exhale a large amount of carbon dioxide. .

4. Gas lighter should not be used
Some drivers have the habit of smoking and often put the gas lighter used to light cigarettes on the hood, which is very dangerous. As is known to all, for single-use gas lighters, when the plastic container containing liquid gas is subjected to heavy blows or high temperatures above 40 degrees, the gas expands due to heat, and the plastic shell may explode due to the shock or heat. Although the explosion of the gas lighter is not powerful, an explosion occurs near some fuels and flammable materials in the car. Once a fire occurs, the consequences will be unimaginable.
