Academics said the impact of sitting for periods of six hours could be setting the stage for heart attacks and strokes
Parents should limit the amount of time children spend on social media and video games, researchers have said, after a new study found inactive teenagers are more likely to have signs of heart damage when they are young adults. Academics said that this heart damage could be setting the stage for heart attacks and strokes in later life.
This assessment was repeated when they were 15 and again when they were 24. Researchers also performed ultrasound scans on the hearts of older teenagers and young adults. The researchers found that each one-minute increase in sedentary time from 11 to 24 years old was associated with a 0.004g/m2.7 increase in left ventricular mass between 17 and 24 years old. “All those hours of screen time in young people add up to a heavier heart, which we know from studies in adults raises the likelihood of heart attack and stroke,” said study author Dr Andrew Agbaje of the University of Eastern Finland.

Researchers identify mathematical rule behind the distribution of neurons in our brainsHuman Brain Project (HBP) researchers from Forschungszentrum Jülich and the University of Cologne (Germany) have uncovered how neuron densities are distributed across and within cortical areas in the mammalian brain. They have unveiled a fundamental organizational principle of cortical cytoarchitecture: the ubiquitous lognormal distribution of neuron densities.
