There is nothing else but economy that occupies the minds of Americans at present times of economic crisis（危机）. The statistics on unemployment，housing costs and consumer confidence keep coming and coming，leaving people not just scared to spend money but also very stressed and emotionally exhausted. This stress has an effect on everything，starting with our sleep，mood，physical health，relationships and eating habits.

“Time of economic stress leads to increase rates of depression(忧郁)，”says Dr. Christopher Palmer，director of continuing education at McLean Hospital in Belmont，Massachusetts. “It worsens illness in people who have been constantly depressed. But it also causes new cases of depression. Just the fear of losing one’s job can put people over the edge. ”

And，without any doubt，just depression alone can create a variety of bad health effects.

●Sleep

33 percent of Americans reported that they have lost sleep due to the economic crisis. 26 percent say they are sleeping less than 6 hours per night，which is considered to be at least one hour less than the most favorable 7 to 8 hours recommended by sleep experts.

●Mental health，stress and heart attack

80 percent of Americans reported that last year the economy is a huge source of stress; 49 percent said the situation makes them feel nervous or anxious; 48 percent reported that they feel very sad and have developed depression.

Nearly twice the risk of heart attack or death was found in patients with the highest levels of depression or anxiety. Among those individuals，a 10 percent higher rise of heart attack or death was found in those whose anxiety rose over time.

●Relationships

The chances of violent behavior are nearly 6 times higher for individuals who are left without a job. Workplace stress can lead to domestic violence.
