Excessive screen time linked to stroke risk, new research shows. People who spend too much time on a computer, watching TV, and other sedentary activities have a higher stroke risk than people who are more physically active, the latest research states.
The latest research findings appear in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
American Heart Association statistics reports that American adults spend an average of 10.5 hours daily connected to media such as smartphones, computers, or television watching. Data also shows that rates of stroke-related deaths declined in 2010 among adults 65 years and older.
In the new study, the researchers reviewed health and lifestyle information for 143,000 adults without prior stroke, heart disease, or cancer who participated in the Canadian Community Health Survey. Researchers tracked the participants for an average of 9.4 years.
The overall study found that those who reported eight or more hours of sedentary time and low physical activity was 7 times more at risk of stroke compared to those reporting less than four hours of sedentary time per day and higher levels of physical activity.
"Adults 60 years and younger should be aware that very high sedentary time with little time spent on physical activity can have adverse effects on health, including increased risk of stroke," study author Raed A. Joundi, M.D., D.Phil said.
Joundi also said that physical activity reduces the actual time spent sedentary, and it also declines the negative impact of excess sedentary time.
