Psychologists confirm the value of vacations for the mind.“The impact that taking a vacation has on one’s mental health is great，” said Francine Lederer，a clinical psychologist in Los Angeles who specializes in stress and relationship management.“Most people have better life perspective and are more motivated to achieve their goals after a vacation，even if it is a 24­hour time­out.” The trips could be good for their health，good for their family and good for their businesses.

　　The online travel agency Expedia conducted a survey about vacation time in 2010，and according to their data the average American earned 18 vacation days—but only used 14 of them.France topped the list，with the average worker earning 37 vacation days and using all but two of them.Americans’ responses may not be surprising in a culture where long hours on the job often are valued，but that’s not always good for the individual，the family or the employer.

　　Psychologists have also found that people who don’t take enough time to relax may find it harder to relax in the future.“Without time and opportunity to do this，the nerve connections that produce feelings of calm and peacefulness become weaker，making it actually more difficult to shift into less­stressed states，” Mulhern said.
