In a world dominated by technology, where the notion of “disconnecting” often seems irresponsible to our modern way of life, sleep, one of the fundamental pillars of health, is under threat. Amid the hustle and bustle of daily life, many of us stay connected to our devices at night, whether to watch a series, browse social media, or simply check work emails. However, this nighttime interaction with technology is having a deeper impact on our sleep than we may realize.

A study published in the Journal of Applied Physiology in 2015 revealed that exposure to blue light emitted by electronic devices, such as smartphones and laptops, before bed can reduce the production of melatonin, the sleep-inducing hormone, by up to 22%. This impact on melatonin not only makes it harder to fall asleep but also affects the quality of sleep.

Delving deeper, we can identify the following challenges

Disruption of the Biological Clock

Constant exposure to blue light can trigger an imbalance in our circadian rhythm, leading to irregular sleep patterns and, in many cases, insomnia.

Reduced Sleep Quality

Even if we manage to fall asleep after prolonged device use, the quality of sleep can be compromised, leading to fragmented and less restorative sleep.

Impact on Mental Health

The lack of quality sleep is directly linked to issues such as depression, anxiety, and stress. According to the book “Why We Sleep” by Matthew Walker, a single night of insufficient sleep can amplify feelings of sadness or anxiety by up to 30%.

So, how can we reconcile our dependence on devices with the vital need for quality sleep?

Establish a Disconnect Routine

Develop the habit of “turning off” all devices at least an hour before bed. This helps signal to the body that it is time to relax and prepare for sleep.

Ideal Sleeping Environment

Keep your bedroom dark and cool. Consider using blackout curtains and avoid devices with bright LED lights in the room.

Night Modes

If you need to use a device at night, use night modes or apps that reduce blue light emission.

Prioritize Sleep

Remember that sleep is not a luxury but a fundamental necessity. Establish a regular sleep routine and stick to it, regardless of digital demands.

Always remember not to get lost in using your phone for hours and practice good sleep hygiene, so you have vitality and energy throughout the day.
