Workers who commute by car, bus or train to the office are more likely to suffer from stress and exhaustion, according to a study. Scientists studied 12,000 employees aged between 18 and 65.They found that those who traveled to work by car or public transport reported higher levels of stress and tiredness compared to active commuters who traveled by foot or bicycle. The negative health of public transport users increased with journey time.       It is now expected that the study, from Lund University in Sweden, will encourage further   investigation into the health effects of commuting and the best forms of transportation.       Researcher Erik Hansson said:"Generally car and public transport users suffered more   everyday stress, poorer sleep quality, exhaustion and felt that they struggled with their health   compared to the active commuters."       According to the Office for National Statistics, the average Briton commutes 54 minutes   every day.       But now the scientists claim that the advantages of daily travel, such as higher pay or   housing conditions, need to be weighed against the negative health effects. Income, family background and environmental factors are other things that need to be considered.     It may also have a cost effect on industry. According to a Absence and Workplace Health   Survey, the U.K. economy lost 190 million working days to absence last year, with each employee taking an average of 6.5 days off sick, costing employers US$27 billion.     Hansson added that findings would help to reconsider the balance between economic needs, health, and the costs of working days lost. However, researchers stress that the findings, published in the journal BMC Public Health, do not prove that commuting causes ill health and   further research is needed. The supporters of daily travel will insist that it brings  _  .
