Scientists believe kids who lead a sedentary lifestyle are more likely to have an elevated blood pressure, regardless of whether they are obese or not.

Researchers from Iowa State University and the Spanish National Research Council in Madrid examined the link between sedentary behavior – such as watching TV, playing video games, painting or sitting – and elevated blood pressure in 111 children aged 3 to 8.

“TV viewing and screen time [defined as the total amount of time spent using a TV, video, computer or video game] were positively associated with both systolic blood pressure and diastolic blood pressure after adjusting for potential confounders,” the authors wrote in the Archives of Pediatrics & Adolescent Medicine.

This study adds to the growing body of evidence which suggests that although there are genetic factors contributing to an elevated blood pressure, lifestyle choices such as physical activity or diet seem to be relevant contributors as well in children and adults alike.

Among natural remedies for circulation problems are nutritional supplements containing folic acid. According to About.com, an informational website, it may help lower high blood pressure in some people, possibly by reducing elevated homocysteine levels.
