Future health risks when sitting in front of the screen

In the first study in the world, researchers at the University of Sydney, Australia, discovered that 6-year-old children, most of the time in the day, the children just watched television, were right away. At this age, the arteries in the retina of these children will be narrowed, increasing the chances of heart disease, high blood pressure and diabetes in later life.

Children watch TV for too long during the day, then the arteries in the retina of these children will be narrowed

The results of this study were published in Arteriosclerosis, Thrombosis and Vascular Biology: The Journal of the American Heart Association, published this week, showing health risks increased proportionately: every hour in the day that your child sits in front of a television screen, it corresponds to a 10 mm increase in systolic blood pressure, the researchers said.

Researchers surveyed about 1,500 children, aged between 6 and 7, in 34 elementary schools in Sydney, Australia. Children who regularly participate in outdoor physical activity have a greater average width of the retinal artery (artery behind the eyes) than those of children with outdoor activity levels. the shortest.

" We found that in children with high levels of physical activity, there will be more tiny blood vessels than children with the lowest levels of physical activity ," according to the doctor. Gopinath Bamini, the lead author and leading researcher, works at the Center for Visual Research, University of Sydney, Australia.

"This shows that elements of unhealthy lifestyles can soon affect blood microcirculation in the early stages of life and increase the risk of heart disease and hypertension in later life."

Physical activity enhances blood circulation and has a positive impact on the lining in the blood vessels. The diameter of tiny blood vessels in the retina of childhood, is a sign of the risk of cardiovascular disease and high blood pressure in adults, but this is the first study to show a less active lifestyle. Animations in childhood are related to the narrowing of blood vessels in the retina.

On average, children spend 1.9 hours (nearly 2 hours) each day in front of the screen and 36 minutes a day in the physical activity organization. In order to be truly healthy, children only need to spend more than an hour or more for physical activity, a lot of movement that helps children have a significantly larger diameter of the artery in the retina. than those who only have physical activity for less than 30 minutes / day.

"Having too much time in front of the screen leads to less physical activity, adding that unhealthy eating habits will lead to obesity," Dr. Gopinath said. " Replace 1 hour of the day that your child sits in front of the television screen with outdoor fitness activities, which can bring practical effects in improving the health status of the child, due to the influence of the way. In the present, it also means increasing the number of small blood vessels in the retina of children. "

"Free games should be encouraged and schools should have at least 2 hours a week to allow children to participate in outdoor physical activities. Parents need to ask them to get out of bed and run. Dynamic, instead of letting babies sleep , "Dr. Gopinath said. " Parents can also set an example for their children, by participating in outdoor physical training activities with their children."
