There are many ways and advice that can help people to stay healthy like drinking water, taking vitamins, more exercise etc.

A new study that was published in the International Journal of Behavioral Nutrition and Physical Activity simplifies the key to live longer. It only proposes to swap every 1 hour of sitting every day by means of walking. Death by 12 -14% may decrease according to the study.

In the midst of experiment, the researchers included over 200,000 adults who were middle aged or older.

Based on Centers for Disease Control and Prevention (CDC), 150 minutes of quick walking every week is needed by adults.

Prof. Emmanuel Stamatakis, head study author, comments that preceding studies "established the benefits of adequate physical activity or sleep and the risks of too much sitting, but this is the first to look at what happens when we replace one activity with an equal amount of another."

The team discovered that replacing an hour of sitting each day through standing simply results in 5% decrease in danger of early death. And with those do not have an enough sleep, replacing an hour of sitting with sleeping each day will result to 6% decrease in danger of early death.

Fascinatingly, 13-17% of increase in danger of early death will be acquired when an hour of walking or exercising everyday will be replaced with just sitting or other inactive behaviors.

Prof. Stamatakis noted that "The results show that inactivity is an even bigger health challenge than we initially thought."

"With the average person sitting watching 2-3 hours of TV a day, there is definitely scope for people to get off the couch and be more active. But it's also time for governments to realize that physical activity cannot be treated as the sole responsibility of individuals because we live in a physical activity-hostile world. Finger-pointing at people because they do not do the right thing has not solved any health problem to date, and it is not going to solve the problem of inactivity either," he also added.
