A new app that allows users to schedule when their home broadband Wi-Fi service is available has been launched by Vodafone.
The service enables customers to set timers for their Wi-Fi to switch itself off and to control which devices have connectivity at certain times.
It is hoped this will help young people in particular get a good night's sleep, rather than stay up all night using social networking sites.
According to research by Vodafone, more than 36.5 million under-25s are losing sleep because of excessive social media surfing during the night.
Young Britons were found to be spending an average of 74 minutes on social media before going to sleep, with many worrying that friends and relatives are having a better time than them.
Some 4.5 million under-25s admitted that they check social media after 2am, even if they have to be up in the morning..
David James, Head of Commercial Marketing, commented: "Whilst social media is a great tool to help us keep in touch and inspire us to make more of our time, it’s important to keep a healthy balance.
"With so much usage taking place after bedtime, we are hoping our new broadband service will help customers switch off more easily - putting them firmly back in the driving seat when it comes to managing their sleep.”
Vodafone believes excessive late-night use of social media is an example of the phenomenon that is often termed FOMO - Fear of Missing Out.
Indeed, figures showed that over a third of under-25s experience anxiety as they are worried about missing important posts while they are asleep.
"In our constantly connected world, it’s not uncommon for late night social surfers to suffer from FOMO due to an information overload," Mr James said. "With many not recognising the problem, the solution is harder to see."
