Screen Time and Sleep: What the Research Actually Shows

A staggering 70% of Americans report using electronic devices before bedtime, a habit that can significantly disrupt sleep patterns, according to research from the National Sleep Foundation.

This issue matters now more than ever, as Nashville's thriving wellness scene continues to grow, with new yoga studios and gyms popping up along Church Street and in the Gulch. However, despite the city's emphasis on healthy living, many residents may be unwittingly sabotaging their sleep habits with screen time before bed. The Vanderbilt University Medical Center and the Nashville Public Library have both launched initiatives to promote healthy sleep habits, but more needs to be done to address the specific issue of screen time.

In Nashville, organisations like the YMCA of Middle Tennessee and the Nashville Wellness Center are working to educate residents about the importance of sleep health. The YMCA, with locations on Broadway and in the Belle Meade neighborhood, offers fitness classes and workshops that emphasize the importance of a consistent sleep schedule. Meanwhile, the Nashville Wellness Center on 21st Avenue South provides holistic health services, including sleep coaching and meditation classes, with prices starting at $60 per session.

The Data on Screen Time and Sleep

Studies have 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 were more likely to experience sleep disruptions, with 57% reporting that they woke up during the night. Furthermore, a survey conducted by the Pew Research Center found that 77% of adults aged 18-29 use their phones before bed, compared to 46% of adults aged 50-64.

As of 2022, the average cost of a sleep consultation in Nashville was around $100, although prices can vary depending on the provider and location. The Nashville Health Department has reported that sleep deprivation costs the city an estimated $1.4 million per year in lost productivity. To mitigate this issue, residents can take practical steps, such as using blue light filtering glasses or apps, setting a consistent sleep schedule, and creating a relaxing bedtime routine. By prioritizing sleep health and being mindful of screen time, Nashville residents can improve their overall wellness and quality of life.
