There's now even more incentive to get into shape. A new study suggests that being unfit can be nearly as deadly as smoking.
What researchers found was being physically unfit, like smoking, takes a huge toll on the body's lungs.
MOSES HEPPNER - CLINICAL EXERCISE PHYSIOLOGIST: "The body's ability to retain that oxygen, the body's ability to circulate that oxygen and to get that oxygen throughout the body to muscles, so we can move around."
As we know, being active can improve a person's overall health, but it also help the body to handle trauma better.
so when it comes to exercise, there are general recommendations but there isn't a one-size-fits all.
MOSES HEPPNER - CLINICAL EXERCISE PHYSIOLOGIST: "Exercise has really got to be prescribed to where that individual's at. We have got to find where the limitation is with that activity whether it is endurance, whether it is strength, whether it is balance."
for anyone getting back into physical activity, heppner urges talking to your doctor first and then meeting with a trained, certified individual who can help along the way.
but when it comes to smoking... the american heart association found that millions of children in the U-S are being exposed to secondhand smoke... mainly because their parents are smokers.
researchers found that 41 percent of children ages 3 to 11 had a nicotine metabolite in their blood.
and this is concerning because smoke exposure in children can lead to damaged arteries as well as certain cardiovascular risk factors such as obesity, high cholesterol, and insulin resistance.
children whose parents smoke are also more likely to become smokers themselves.
So, experts encourage parents to quit smoking in order to enhance their health as well as the health of their children.
