Vacations are a chance to take a break from work,see the world and enjoy time with family. But do they make you happier Researchers from the Netherlands set out to measure the effect that vacations have on overall happiness and how long it lasts. They studied happiness levels among 1,530 Dutch adults, 974 of whom took a vacation during the 32-week study period. The study,published in the journal Applied Research in Quality of Life, showed that the largest boost in happiness comes from the simple act of planning a vacation. In the study, the effect of vacation anticipation boosted happiness for eight weeks. After the vacation, happiness quickly dropped back to baseline levels for most people. How much stress or relaxation a traveler experienced on the trip appeared to influence post-vacation happiness. There was no post-trip happiness benefit for travelers who said the vacation was "neutral" or "stressful". Surprisingly,even those travelers who described the trip as "relaxing" showed no additional jump in happiness after the trip. "They were no happier than people who had not been on holiday," said the lead author,Jeroen Nawijn, tourism research lecturer at Breda University of Applied Sciences in the Netherlands. The only vacationers who experienced an increase in happiness after the trip were those who reported feeling "very relaxed" on their vacation. Among those people, the vacation happiness effect lasted for just two weeks after the trip before returning to baseline levels. "Vacations do make people happy," Mr. Nawijn said. "But we found people who are anticipating holiday trios show signs of increased happiness, and afterward there is hardly an effect." One reason vacations don’t boost happiness after the trip may have to do with the stress of returning to work. And for some travelers, the holiday itself was stressful. "In comments from people, the thing they mentioned most referred tc disagreements with a travel partner or being ill," Mr. Nawijn said. The research controlled for differences among the vacationers and those who hadn’t taken a trip, including income level,stress and education. However, Mr. Nawijn noted that questions remain about whether the time of year, type of tril: and other factors may influence post-vacation happiness. According to Mr. Nawijn,one finding of the study is that______.
Many people view retirement as a time to stop working. But new research shows that people who take on full- or part-time jobs after retirement have better health. The finding is based on data collected from 12,189 men and women over a 6-year period. The participant.,;, who were from ages 51 to 61 at the start of the study, answered questions about their employment history, experiences after retirement and their physical and mental health. Researchers from the University of Maryland found that men and women who kept working after retirement had fewer major diseases or disabilities than those who quit work, according to the study. Retirees benefited whether the work was a full- or part-time job, self-employment or temporary. While working after retirement is good for you, the data also suggest that retirees shouldn’t take on just any job. Among those who kept working, the retirees who found work related to their previous careers had the best mental health. The study authors speculated (猜测) that working outside a person’s main area of expertness might lead to more stress. Other studies have also supported the idea that working after retirement is good for you. A long-term study of 1,000 men and women born in 1920 suggested that working after retirement was associated with living longer. The participants joined the study at age 70 and were tracked for 14 years by researchers from the Hadassah Hospital Mount Scopus in Jerusalem. After controlling for individuals’ health at the beginning of the study, the researchers found that whether a person was still alive after 12 years was strongly associated with whether they had been actively working or were fully retired. Among the 1,000 people studied, those who continued to work at age 70 and beyond were 2.5 times as likely to be alive at age 82 as those who had retired and were not working at the beginning of the study. Another study showed that losing a job at an older age can be destructive to health. Yale researchers followed 4,220 workers, ages 51 to 61, for 6 years. During the study period,457 workers lost their jobs. Being laid off close to retirement increased the risk for stroke by three times, according to the study published in the American Journal of Industrial Medicine.
