America’s  No.1 health problem? A report published by the American Institute of Stress claims the biggest threat to health today is neither cancer nor AIDS. The report says: “It has been estimated that75-90 percent of all visits to primary care physicians are for stress related problems”

It is no exaggeration to say that people today are being attacked by stress. According to the National Consumers League, “ Work is the top source of stress for adults who have problems and stress in their lives (39%),followed by family (30%).Other sources include health (10%), concern about the economy (9%)and concern about international conflict and terrorism (4%).”

However , stress is hardly unique to the United States .A British survey in 2013 estimated that “over half a million individuals in Britain believed in 2012 that they were experiencing work –related stress at a level that was making them ill .” As a result of “work –related stress, depression or anxiety ,”there are “an estimated thirteen and a half million reported lost working days per year in Britain .”\

The picture is no less bleak (荒凉的) in mainland Europe .According to the European Agency for Safety and Health at Work , “work-related stress has been shown to affect millions of European Workers across all types of employment sectors .” One survey revealed that there are “about 41 million workers affected by work-related stress each year.”

What about Asia ? A report issued by a conference held in Tokyo concluded: “ Job stress is a  common concern among many countries in the world , both developing and industrialized countries .” The report observed that “several countries in East Asia , including China and Korea, have rapidly industrialized and economically grown .These countries now have a lot of concerns on job stress and its harmful effects on workers’ health.”
