Imagine this: It’s 11 PM. You’re in bed, scrolling through your phone, catching up on emails, social media updates, and the day’s news. Before you know it, an hour has passed, and sleep seems more elusive than ever. This scenario is all too familiar for many of us, especially young professional women striving to balance a demanding career with personal wellness.

In this article, we’ll explore the often-overlooked connection between screen time and sleep quality, offering insights and practical tips for enhancing your digital well-being.

Does Screen Time Affect Sleep in Adults? Understanding Blue Light’s Role

At the heart of our sleep-wake cycle is melatonin, a hormone produced by the pineal gland in the brain. Melatonin doesn’t just help us fall asleep; it’s crucial in regulating our circadian rhythm, the internal clock that dictates our sleep-wake cycle over a 24-hour period. As daylight fades, our melatonin levels naturally rise, peaking in the evening and signaling to our body that it’s time to rest.

However, the pervasive glow of screens from our phones, tablets, and computers emits a significant amount of blue light, which poses a problem for our natural sleep patterns.

Blue light is especially effective at inhibiting melatonin, tricking our brain into thinking it’s still daylight. This disruption leads to a delay in our sleep onset – the time it takes to fall asleep – and can result in shorter sleep duration and less restful sleep.

This effect isn’t just theoretical. Studies have shown that people who use their digital devices before bedtime tend to have poorer sleep quality. They often report taking longer to fall asleep and feeling more tired in the morning.

The correlation between blue light exposure and disrupted melatonin production is a key factor in this phenomenon.

To counteract this, it’s advisable to reduce exposure to blue light in the hours leading up to bedtime.

Using blue light filters on your devices can help, as can engaging in a ‘technology curfew’ – a designated time when you switch off all screens. This allows your body to naturally ramp up melatonin production, preparing you for a restful night’s sleep.

Psychological Effects of Pre-Bedtime Screen Use

But it’s not just the physical effects of blue light we need to be wary of. The content we consume can also play a significant role in how well we sleep.

The last hour before sleep should be a time of unwinding and soothing the mind, yet often, it becomes a battleground against stimulating content.

Engaging with work emails or stimulating social media content can keep our minds active and anxious, hindering our ability to relax and drift off to sleep.

Let’s take Sarah, a 32-year-old marketing executive. She found that her habit of checking work emails before bed was leaving her restless. Once she replaced this with a calming routine of reading and soft music, her sleep improved dramatically. She experienced a remarkable improvement in her ability to relax and drift off to sleep more easily.

By being mindful of not only when but what we engage with digitally before bedtime, we can foster a more restful mind and a mental environment that supports sleep.

It’s about retraining our brains to associate the time before bed with relaxation and peace, rather than the never-ending digital buzz of our day-to-day lives.


Creating a Healthy Digital-Sleep Balance

The key to better sleep in our digital age is finding balance.

Digital minimalism, the art of using technology more intentionally and mindfully, is crucial. It’s about acknowledging that while technology is an essential part of our lives, it doesn’t need to dominate our lives.

For instance, I’ve adopted a simple yet effective change in my nightly routine. Instead of keeping my phone by my bedside, I use a traditional alarm clock and leave my phone to charge in the living room overnight.

This practice, which I’ve maintained for several years now, wasn’t easy at first. However, the benefits became quickly apparent.

I started falling asleep faster, experienced less morning tiredness, and found it easier to get out of bed. This small shift has had a profound impact on my sleep quality and overall well-being.

I can really recommend others to do the same.

Not bringing your phone into the bedroom can help resist the temptation for a ‘last-minute scroll’ (aka hour) before bed and also when waking up.

Additionally, consider using apps that track and limit screen time, aiding in becoming more conscious of your digital habits.



The answer to the question “Does screen time affect sleep in adults?” is a clear “yes”.

There is a link between screen time and sleep quality. By understanding the effects of blue light and being mindful of the digital content we engage with before bedtime, we can take proactive steps towards better sleep.

Experiment with reducing screen time before bed and observe the difference it makes.

Remember, in the quest for a balanced life, how we use our digital devices is as important as how we manage our time offline.
