Swapping just one hour of
sitting with some physical activity such as walking each day, decreases your
chance of an early death by 12 to 14 percent, said a new study that involved
over 200,000 volunteers.
The study found that swapping
even one hour of daily sitting with standing is linked to a five percent
reduction in the risk of premature death.
“Previous research
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,” said lead author
Emmanuel Stamatakis from University of Sydney.
“With the average person
sitting watching two to three hours of TV a day, there is definitely scope for
people to get off the couch and be more active,” Stamatakis added.
The researchers also found
that replacing one hour of sitting with sleeping each day – in those who are
not getting enough sleep – was linked to a six percent decrease in risk of
premature death.
However, risk of an early
death was increased by between 13 and 17 percent when one hour of daily walking
or exercise was substituted with equal amounts of sitting or any other
sedentary activity.
“The important thing for
people to remember is the more you move the better, even if this movement is
incidental or at a light intensity,” Stamatakis said.
“It doesn’t have to be formal exercise in a gym, it can be as simple as
kicking a ball with your kids in the backyard, going for a walk in the
neighbourhood instead of watching another hour of TV, or walking your dog for
an extra half an hour a day,” the researcher explained.
