Spending too much time in front of the TV has been linked with high blood pressure. What makes this finding more startling is that the link has been found in children. 111 three to eight year olds had their activity levels tracked for one week. During this time they wore an accelerometer which measured how active they were and their parents logged how their children spent their time. On average, children were sedentary for five hours a day and the average child was in front of the screen for 90 minutes a day. However, those children who logged the most hours watching TV or playing computer games recorded higher blood pressure levels, compared to those who just watched TV for 30 minutes. Body weight was not an issue. In other words, the health risk was present whether the child was overweight or not. The study was carried out by Eisenmann and colleagues and was published in the Archives of Pediatrics and Adolescent Medicine.
