Too much screen time linked to cancer and heart disease

A new study says too much screen time can lead to cancer and heart disease.

Researchers at the University of Glasgow analysed the amount of time 390,089 people spent looking at TV and computer screens during leisure time.

Professor Jason Gill one of the lead authors of the study, said:

Our study shows that the risks associated with sedentary behaviour may not be the same for everyone, with the association between leisure time screen use and adverse health outcomes being strongest in those with low levels of physical activity, fitness or strength.
This has potential implications for public health guidance as, if the findings are causal, these data suggest that specifically targeting those with low fitness and strength to reduce their sedentary behaviour may be an effective approach.
