In the modern society, the development of transportation has made it easier for many people to travel, and affordable buses have become the priority choice of many people, especially some elderly friends must pay attention to avoid peaks when riding the bus. Long-term use of air-conditioned cars, etc., should always pay attention to their health.

　　 Scenario 1. An old man In a hurry, the bus was very crowded during peak hours. Suddenly, a sudden brake stopped. The elbow of the person next to him protruded on his rib. He suddenly felt unusual pain. He went to the hospital to take a film and found that it was a broken rib.

　　Explaining doubt: Due to the severe winter, many elderly people’s outdoor activities have decreased, and the time they lie or sit at home is relatively extended. Due to reduced exercise, there are not many opportunities for sun exposure, resulting in increased bone calcium loss and further increased osteoporosis, which is prone to fractures. Generally speaking, the ribs are more likely to be crushed.

　　Recommendation: It is best to stagger travel during peak hours and avoid getting in a crowded car.

　　 Scenario 2. Some elderly people make air-conditioned buses for a long time, the air is not circulating, they are dizzy and dizzy, and they get off and fall down, resulting in fractures.

　　Explaining doubt: Winter is a high incidence of cardiovascular and cerebrovascular diseases. Sometimes even transient cerebral ischemia can cause the patient to fall and produce fractures. If the patient''s consciousness is unclear after falling, the doctor should pay more attention to the diagnosis of cerebrovascular diseases, fearing that the consciousness is confused, and some people will be ignored. When I meet an elderly patient with a fracture, I always ask him first: Did you accidentally fall, or did you fall after dizziness? Generally speaking, the elderly without cerebrovascular problems can clearly explain the cause of the fall. For the unexplained elderly, it is necessary to pay attention to the head condition that caused the fall while treating the fracture.

　　Recommendation: Old people with cerebrovascular disease should not take the bus for a long time. Once you fall, if you are not conscious, you must pay attention to the possibility of complicated cerebrovascular disease. You must not only focus on fractures and ignore more serious cerebrovascular diseases. Therefore, the elderly should not ride on overcrowded buses.
