Travel disorder, a mental disease induced by the noise of tires during long journeys in crowded transports, is a new threat to the health of citizens, the Oriental Morning Post reported today.
As the spring festival draws near, the passenger occupancy rate on most trains to the center of China has increased from 50 percent to over 75 percent.  The public security section of local railway station has indicated that since this January twelve mental patients have been detected on trains heading for Kunming, Chengdu and Beijing.
Professor Li Chunbo, vice director with the psychiatry instruction and research center of Tongji University, explained that exhaustion might lead to mental health problems.  The disease is characterized by slow reactions, fuzzy vision, hallucinations, and even suicide or aggression.
