Screen time and sleep: what the research actually shows

A staggering 70% of adults in Edinburgh report using electronic devices before bedtime, according to a recent survey by the University of Edinburgh. This habit is having a significant impact on sleep quality, with many residents struggling to get the recommended 7-9 hours of sleep per night.

The issue of screen time and sleep is particularly relevant in Edinburgh, where a thriving tech industry and vibrant cultural scene can make it difficult for residents to disconnect from their devices. With many cafes and coworking spaces, such as those found on George Street and the Royal Mile, offering free Wi-Fi and encouraging customers to stay connected, it can be hard to resist the temptation to scroll through social media or check work emails before bed.

In Edinburgh, organisations such as the Edinburgh Leisure programme and the NHS Lothian's Sleep Clinic are working to promote healthy sleep habits and provide support for residents struggling with sleep disorders. The City of Edinburgh Council has also launched initiatives to improve street lighting and reduce noise pollution in areas such as the Old Town and Leith, which can help create a more sleep-friendly environment. Additionally, local businesses like the Balmoral Hotel and the Sheraton Grand Hotel & Spa are offering sleep-focused packages and amenities, such as blackout curtains and white noise machines, to help guests get a good night's sleep.

The science behind screen time and sleep

Research has shown that exposure to screens and the blue light they emit can suppress the production of melatonin, the hormone that regulates sleep. A study published in the journal Sleep Health found that adults who used electronic devices before bedtime took longer to fall asleep and had poorer sleep quality than those who did not. In fact, the study found that using a smartphone or tablet before bed can lead to a 30-minute delay in falling asleep, and can also reduce sleep duration by up to 1 hour. With the average cost of a sleep consultation in Edinburgh ranging from £50 to £200, and the cost of sleep-related problems to the NHS estimated to be around £1.5 billion per year, it's clear that addressing the issue of screen time and sleep is a priority.

So what can Edinburgh residents do to improve their sleep health? The NHS recommends establishing a consistent bedtime routine, avoiding screens for at least an hour before bedtime, and creating a sleep-friendly environment. This can include making simple changes such as using dim red lights instead of bright white lights, keeping the bedroom cool and quiet, and investing in a good mattress. With the help of local organisations and businesses, Edinburgh residents can take steps to prioritise their sleep health and wake up feeling rested and refreshed. By making a few small changes to their evening routine, residents can improve the quality of their sleep and wake up feeling more alert and focused, ready to take on the day in this vibrant and bustling city.
