The panic of forgetting your phone at home is a distinctly “this century” problem. It’s uncomfy even if you weren’t really planning on using it. It feels like the moment you remember that the skirt you ransacked your closet for to complete a killer outfit is the one you already gave away.
So yeah, many of us are a little addicted to our smartphones—specifically, the digital media we consume on them. How bad is this for our brains, though?
“Digital media is not all or none. It is here to improve and enhance our lives if we make the effort to be mindful about how we are using it,” says sleep neurologist and Ozlo Sleep Medical Advisory board member, Meredith Broderick, MD.
Below, she explains how digital media affects the brain, and shares tips for using your screen time more mindfully.
How does digital media affect the brain?
“Since the turn of the millennium, behavioral (as opposed to substance) addictions have soared,” writes The Guardian. “Every spare second is an opportunity to be stimulated, whether by entering the TikTok vortex, scrolling Instagram, swiping through Tinder, or binging on porn, online gambling, and e-shopping.” This is partly due to dopamine.
As we previously wrote, “In terms of our reward pathways, when we do something that’s perceived as pleasurable, dopamine says, ‘Hey, we should do that again.’ It tells your brain to repeat a behavior that brings pleasure, rather than directly causing the pleasure.” The dopamine bursts we get from social media can actually make it addictive.
Here are a few more ways that consuming digital media affects our brains:
-
Attention issues:
“Consuming digital media that consists of scrolling through content, requiring a lot of multi-tasking, and attentional shifts, has an association with ADHD symptoms,” Dr. Meredith says. “A meta-analysis showed a correlation between digital media use and attention problems.”
-
Sleep problems:
“Computers and phones emit blue light that suppresses melatonin secretion and may disrupt our circadian rhythms, which reduces sleep duration and sleep quality,” she says.
Plus, scrolling through an app like TikTok can actually be addictive, which can play a role in “revenge bedtime procrastination.”
-
Social isolation:
“One of the main drawbacks of using social media platforms is linked to social isolation, which may impede social connection,” Dr. Meredith says. “Studies have also shown that time away from screens improves emotional and social intelligence.”
-
Stronger brain circuits:
Yes, this one’s a positive. “Some research has shown that searching online is a form of mental exercise that may strengthen brain circuits,” she says.
“Remember that the effect of spending time on a screen isn’t just about the time spent on the screen. It’s also about the time not spent doing other things, like interacting and connecting with others, reading, physical activity, and experiencing nature,” she adds.
Are there any benefits of digital media?
It’s not all bad!
“Digital media provides opportunities to access resources like telehealth services,” Dr. Meredith says. “It can also be used to strengthen cognitive skills with training and neural exercise programs.” She also says digital media can be educational “when it is directed and guided by adults/parents.”
Additionally, “digital media apps like the one created by Ozlo Sleep can deliver health solutions to people living with problems like sleep disturbances and tinnitus,” she says.
