Instead of working overtime in hopes of getting a pay rise, maybe you should go to the gym, as itcould make you just as happy as that extra money.
An interesting new study shows people who are physically active have a greater sense of well-being(幸福) than those who are inactive, and that active people feel as good as inactive people who earn$25,000 more per year.
Researchers from Oxford and Yale Universities used data collected from
1.2 million Americans. They were asked, "How many times have you felt mentally unwell in the past 30 days, for example because of stress, depression, or emotional problems? " They were also asked about their exercise habits, choosing from 75 different physical activities, including mowing the lawn, doing housework ，running, weightlifting, and cycling.
The researchers found that people who exercised often felt bad for an average of 35 days per year while inactive people felt bad for an additional 18 days. All exercise types had a good influence. Social physical activities, for example team sports, were considered to have a better influence although cycling ranked highly.
However, it is possible to get too much exercise. According to a study, the mental health of those who exercised for more than three hours a day suffered more than that of those who weren't physically active.
The proper amount seems to be three to five times per week, lasting 30 to 60 minutes each.
