Using mobile phones or watching TV in a dark bedroom just ahead of bedtime can sabotage your sleep more than when used in a well lit room or not using them at all, researchers say.

“While previous research has shown a link between screen use and the quality and length of young people’s sleep, ours is the first study to show how room lighting can further influence this,” said lead author Michael Mireku from the University of Lincoln in the UK.

Insufficient sleep is associated with impaired immune responses, depression, anxiety and obesity in children and adolescents.

The study, published in the journal Environment International, found that night-time use of phones, tablets and laptops is consistently associated with poor sleep quality, insufficient sleep, and poor perceived quality of life.

For the study, the research team collected data from 6,616 adolescents aged between 11 and 12 and more than 70 per cent reported using at least one screen-based device within one hour of their bedtime.

They were asked to self-report a range of factors including their device use in both lit and darkened rooms, their weekday and weekend bedtimes, how difficult they found it to go to sleep and their wake up times.

The results showed that those who used a phone or watched television in a room with a light on were 31 per cent more likely to get less sleep than those who didn’t use a screen.

The likelihood increased to 147 per cent if the same activity took place in the dark.

It has been reported that globally, 90 per cent of adolescents are not sleeping the recommended nine to 11 hours per night, which has coincided with an increase in the use of screen-based media devices.

Previous studies have shown that sufficient sleep duration and quality are vital in childhood to maintain physical and mental development. (IANS)

The global market for refurbished smartphones slowed to one per cent year-over-year (YoY) growth in 2018, reaching close to 140 million units, Counterpoint Research said on Thursday.

According to Counterpoint’s “Refurbished Smartphone Tracker”, the secondary industry slowed due to the 11 per cent drop in new smartphone sales in key supply countries like China and the US. The drop in new device sales led to a decline in devices flowing into the secondary market.

Samsung and Apple continued to dominate the refurbished market with 70 per cent share while Huawei is growing in popularity, especially in South East Asia.

“The US and China markets saw lower upgrade cycles in 2018, which affected the flow of devices into the secondary market. In addition, China and US trade tensions held up devices in customs much longer than normal. This was especially true during the first half of the year,” Tom Kang, Research Director at Counterpoint Research, said in a statement.
