Sheffield Research Reveals How Screen Time Disrupts Sleep Quality

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 Sheffield adults reporting that they use electronic devices at least an hour before bedtime.

This matters now because sleep deprivation can have serious consequences for our physical and mental health, including increased risk of obesity, diabetes, and cardiovascular disease. In Sheffield, where an active wellness culture is thriving, it's essential to consider the role of screen time in our sleep habits. The city's many parks and green spaces, such as Endcliffe Park and Millhouses Park, offer ample opportunities for outdoor activities and exercise, but a good night's sleep is also crucial for overall wellbeing.

In Sheffield, organisations such as the Sheffield Wellness Centre on Glossop Road and the NHS-funded Sheffield Healthy Weight programme are working to promote healthy lifestyle choices, including sleep hygiene. Local businesses, like the cafes on Division Street and the gyms on Ecclesall Road, are also starting to take notice of the importance of sleep health, with some offering sleep-focused workshops and classes. The University of Sheffield's Department of Psychology is also conducting research into the effects of screen time on sleep, with a recent study finding that students who used screens for more than two hours before bed were more likely to experience sleep disturbances.

What the data shows

According to a survey conducted by the Sheffield City Council, 60% of residents report using their phones or tablets in the hour leading up to bedtime, with 40% saying they check their work emails or take work calls during this time. The same survey found that 25% of respondents get less than 7 hours of sleep per night, with 15% reporting that they wake up feeling tired or unrefreshed. A study published in the journal Sleep Health found that adults who used screens for more than 30 minutes before bed were 25% more likely to experience sleep disruptions, with the average cost of sleep disorders to the NHS estimated to be around £1.4 billion per year.

As the city continues to promote its active wellness culture, it's essential that residents are aware of the potential impact of screen time on their sleep health. By making small changes to their evening routines, such as reading a book or taking a warm bath instead of scrolling through their phones, Sheffield residents can improve the quality of their sleep and wake up feeling refreshed and revitalised. The Sheffield Wellness Centre is offering a series of sleep-focused workshops, starting from £10 per session, and the NHS is providing free sleep hygiene guidance on its website, making it easier for residents to take control of their sleep health.
