Screen time and sleep: what the research actually shows

A recent study has found that exposure to screens and the blue light they emit can suppress melatonin production, leading to poorer sleep quality and duration, with 70% of adults in the UK reporting that they use electronic devices before bedtime.

This matters now because Edinburgh, with its thriving active wellness culture, is home to a population that values health and wellbeing. From the bustling streets of the Old Town to the leafy suburbs of Morningside, residents are always looking for ways to improve their lifestyle. With the city's numerous gyms, yoga studios, and healthy eating establishments, such as the popular cafe on Bruntsfield Place, it's clear that Edinburgh residents are invested in their wellbeing. However, despite this focus on health, many are still unaware of the negative impact that screen time can have on their sleep.

In Edinburgh, organisations such as the Edinburgh Leisure programme and the NHS Lothian's Health Improvement Team are working to promote healthy sleep habits. The City of Edinburgh Council has also launched initiatives to encourage residents to get outside and be active, such as the Innocent Railway Path and the Water of Leith Walkway, which can help to improve sleep quality. Additionally, local businesses like the Edinburgh Bicycle Co-op on Causewayside are promoting cycling as a way to reduce screen time and improve overall health.

The science behind screen time and sleep

Research has shown that the blue light emitted from screens can suppress melatonin production by up to 55%, making it harder to fall asleep and reducing sleep quality. 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 Edinburgh, a survey conducted by the University of Edinburgh found that 60% of students reported using their phones before bedtime, with 40% reporting that they had trouble sleeping as a result.

So what can Edinburgh residents do to reduce the impact of screen time on their sleep? The NHS recommends avoiding screens for at least an hour before bedtime, and using blue light filtering glasses or apps. Residents can also take advantage of the city's many outdoor spaces, such as Holyrood Park or the Meadows, to get some exercise and fresh air during the day. By making a few simple changes to their bedtime routine, Edinburgh residents can improve their sleep health and wake up feeling rested and refreshed. With the average adult in the UK spending around £500 per year on sleep-related products, such as mattresses and sleep aids, it's clear that getting a good night's sleep is a priority for many.
