In the past, Koreean highways and city intersections were incredibly confusing. When approaching a largejuction (a place where multiple roads meet) , drivers had to quickly read multiple overhead signs. This confusion caused drivers to change lanes at the last minute, leading to severe traffic accidents. In March 2011, a tragic and fatal traffic accident occurred at the Ansan Juction on the West Coast Expressway. A paassenger car and a cargo truck crashed simply because they were confused about which lane to take. In fact, this area always used to be a frequent car accident spot, with 20~30 traffic accidents occuring every year. So Mr. Yoon Seok-deok, an employess of the Korea Expressway Corporation wanted to do something about this problem. One day, he went home and watched his children drawing pictures on the floor with colorful paint and crayons. Watching them , a brilliant idea flashed in his mind: what if we colar the roads just like my children's drawings,...
The reason why you should drink a lot of water when you catch a cold.
When you have a cold, you may have heard of the idea of drinking a lot of water. It is to prevent dehydration. When people are sick, they read their desire to eat or drink, which leads to dehydration.
Also, when you get a fever, you lose moisture in your body. Even if the body temperature is about one degree higher than normal, the water in the body does not evaporate rapidly, but body heat accelerates metabolism, exhaling more carbon dioxide and requiring more oxygen. Therefore, your breathing speeds up and every time you exhale, moisture is carried away.It spouts water like a whale with hot air. David takes a similar example of the accumulation of saliva inside a brass instrument.
The body tries to fight against heat because it is dangerous in many ways when the fever rises. The main way is to release moisture through the skin. Although this moisture is invisible, it can sometimes appear as sweat. When the heat reaches a life-threatening point, the human body becomes drenched.
Drinking a lot of water is the best way to make up for lost moisture due to sweat, breathing, and evaporation. From a medical point of view, it is particularly important to prevent dehydration.
Frank Davidov, the National Council of Medical Professors in Philadelphia explained why we should be good children who obey doctors and why a cold causes dehydration.
Dehydration is undesirable in any situation. Especially when you have symptoms of infection such as a cold, it can have very dangerous consequences.Dehydration causes constipation.If you don't have enough rest or food intake, constipation worsens, which cane be a complex effect when you catch a cold.
Most importantly, it thickens the mucus secreted from the nasal cavity and bronchial tubes. The thick mucus blocks the nasal passages and bronchial tubes. As a result of this, not only do you feel uncomfortable,but also the level of infection is further worsened, causing lung cells to die, furthermore, infectious bacteria may enter the lungs to develop pneumonia.
* Cold symptoms appear 24 hours after one of the 100 kinds of viruses invades through the air passage from the nose to the throat. The most common virus is a nasal virus, which is much smaller than bacteria, but has the power to withstand temperatures as low as -93 degrees Celsius and 100,000 times the force of Earth's gravity.
