Using a phone or watching TV in the dark before bed makes pre-teen children far less likely to get a good night’s sleep, research has found.

Those who used a phone or watched television in a room with a light on were 31% more likely to get less sleep than those who didn’t use a screen. The likelihood increased to 147% if the same activity took place in the dark.

The study, published in Environment International, collected data from more than 6600 11- and 12-year-olds.

Lead author Dr Michael Mireku, of the University of Lincoln, said: ‘Our findings are significant not only for parents but for teachers, health professionals and adolescents themselves.’
