Researchers of a sedentary lifestyle study have good news for office workers who find themselves trapped behind a desk every day from 9 to 5. The negative health effects created by long hours of sitting down can be reduced by daily exercise.

The study looked at data from 16 previous studies, mainly involving people ages 45 and above from the United States, Australia, and Western Europe. They found during their follow-up period of two to 18 years that those who sat for eight hours a day with little exercise had a 9.9 percent chance of mortality, while those who sat for less than four hours per day with one hour of exercise had a 6.8 percent chance of mortality.

The study goes on to recommend that those who sit daily for an average of eight hours should try to exercise one hour per day, while those who sit 6 or less should aim for half an hour of exercise.
