While initial exercise cut death rates by 14 percent, additional 15 minutes of activity further reduced the rate by four percent.
This trend continued until a person raised exercising to 100 minutes daily, after which no further benefit was derived, daily reports.
"Individuals who did a daily average of 15 minutes of moderate-intensity exercise had significant health benefits compared to individuals who were inactive," said research leader Chi-Pang Wen from the National Health Research Institutes (NHRI) in Taiwan.
Exercise seemed to protect against cancer. People termed 'inactive' had an 11 percent higher risk of dying of cancer than those in the 'low-volume' activity group.
Cancer deaths fell by one percent for each additional 15 minutes of daily exercise after the first 15 minutes. The study involved more than 400,000 people aged 20 and above, between 1996 and 2008 in a medical screening programme of the NHRI.
