In collaboration with One-Beat Medical, the Greater Miami-Fort Lauderdale Chapter of the American Heart Association is scheduling visits to local businesses, churches and schools for onsite CPR training.

Staff at Local 10 took part in sessions this week.

“And really, hands only CPR is two steps -- you’re going to call 911, then you’re going to push fast and hard in the center of the chest, so it’s really easy, you’re going to go to https://www.heart.org/ and you’re going to see an instructional video. It’s really, really simple,” said Marisol Garcia, Executive Director of the Greater Miami-Fort Lauderdale chapter of the AHA.

According to the American Heart Association, three out of four cardiac arrests happen outside of the hospital, which means knowing hands only CPR will likely save the life of someone you love.

Also in today’s health news, there’s more data this week about the impact of sleep duration and heart health.

Researchers found those who slept less than five hours or more than nine hours were at greater risk of having a heart attack.

They say the central issue is that people with sleep problems tend to have elevated blood pressure at night.

About 10 to 15 percent of Americans suffer from insomnia.

And researchers have found a nationwide association between Parkinson’s disease and air pollution.

The relative risk for Parkinson’s increased by 25 percent in areas of the country with high levels of fine particulate matter, a measure of pollution.

A study limitation is that fine particulate matter contains a variety of airborne pollutants, some of which may be more toxic than others.

Studies have also linked pollution to other health risks, including dementia and heart disease.
