According to research conducted by Yale and Oxford, working out is more important for your happiness than the money you have in your bank account.

The study has proven that people who exercise regularly tend to feel bad for 35 days a year where as people who do not exercise feel bad for 53 days. The study has also indicated that certain sports which involve socializing, such as going to the gym, have a greater impact on your mental health than other sports.

The researchers found that physically active people feel just as good as those who don't do sports but who earn about $25,000 more a year. This means if you don’t exercise you would have to earn more money to get you to the same happiness level with the people who exercise.

Note that it doesn’t mean that the more your exercise, the happier you are. Exercising too much can have a negative impact on your happiness.

"The relationship between sport duration and mental load is U-shaped," said study author Adam Chekroud of Yale University in an interview with Die Welt. According to the study, exercising 3 to 5 times a week, for 30 to 60 minutes is ideal. If you exercise for more than 3 hours a day, your happiness level will be lower than those who do not exercise.

This study was published by The Lancet.
