6 Ways electronic screen time makes kids angry, depressed and unmotivated
The child or teen who is “revved up” and prone to rages or—alternatively—who is depressed and apathetic has become disturbingly commonplace. Chronically irritable children are often in a state of abnormally high arousal, and may seem “wired and tired.” That is, they’re agitated but exhausted. Because chronically high arousal levels impact memory and the ability to relate, these kids are also likely to be struggling academically and socially.
At some point a child with these symptoms is likely to be given a mental health diagnosis, such as major depression, bipolar disorder, or ADHD, and offered corresponding treatments, including therapy and medication. But often, particularly in today’s world, these treatments don’t work very well, and the downward spiral continues. What’s happening?
The problem is that both parents and clinicians are “barking up the wrong tree.” That is, they’re trying to treat what looks like a textbook case of “X” mental disorder, but failing to rule out and address the most common environmental cause of such symptoms: everyday use of electronics. Time and again, I’ve realized that regardless of whether there exists any “true” underlying diagnoses, successfully treating a child with mood dysregulation in this day and age requires methodically eliminating all electronics use for several weeks –an “electronic fast”– to allow the nervous system to “reset.”
If done correctly, this intervention can produce deeper sleep, a brighter and more even mood, better focus and organization, and an increase in physical activity. The ability to tolerate stress improves, so meltdowns diminish in both frequency and severity. The child begins to enjoy the things they used to, is more drawn to nature, and imaginary or creative play returns. In teens and young adults, an increase in self-directed behavior is observed – the exact opposite of apathy and hopelessness.
It’s a beautiful thing.
At the same time, the electronic fast reduces or eliminates the need for medication while rendering other treatments more effective. Improved sleep, more exercise, and more face-to-face contact with others compound the benefits…an upward spiral! After the fast, once the brain is reset, the parent can carefully determine how much if any electronics use the child can tolerate without symptoms returning.
Restricting electronics may not solve everything, but it’s often the missing link in treatment when kids are stuck.
But why is the electronic fast intervention so effective? Because it reverses much of the physiological dysfunction produced by daily screen-time.
Children’s brains are much more sensitive to electronics use than most of us realize. In fact, contrary to popular belief, it doesn’t take much electronic stimulation at all to throw a sensitive and still-developing brain off track. Also, many parents mistakenly believe that interactive screen-time—such as internet or social media use, texting, emailing, and gaming –isn’t harmful, especially when compared to passive screen-time like TV. But in fact, interactive screen-time is more likely to cause sleep, mood, and cognitive issues, because it’s more likely to cause hyperarousal and compulsive use.
Here’s a look at six physiological mechanisms that explain electronics’ tendency to produce mood disturbance:
1. Screen-time disrupts sleep and desynchronizes the body clock. Because light from screen devices mimics daytime, it suppresses melatonin, a sleep signal released by darkness. Just minutes of screen stimulation can delay melatonin release by several hours and desynchronize the body clock. Once the body clock is disrupted, all sorts of other unhealthy reactions occur, such as hormone imbalance and brain inflammation. Plus, high arousal doesn’t permit deep sleep, and deep sleep is how we heal.
2. Screen-time desensitizes the brain’s reward system. Many children are “hooked” on electronics, and in fact gaming releases so much dopamine — the “feel-good” chemical — that on a brain scan it looks the same as cocaine use! When reward pathways are overused, they become less sensitive, and more and more stimulation is needed to experience pleasure. Meanwhile dopamine is also critical for focus and motivation. Needless to say, even small changes in dopamine sensitivity can wreak havoc on how well a child feels and functions.
3. Screen-time produces “light-at-night.” Light-at-night from electronics has been linked to depression and even suicide risk in numerous studies. In fact, animal studies show that exposure to screen-based light before or during sleep causes depression even when the animal isn’t looking at the screen. Sometimes parents feel scared to restrict electronics use in a child’s bedroom because they worry the child will go enter a state of total despair — but in fact removing light-at-night is protective.
4. Screen-time induces stress reactions. Both acute stress (fight-or-flight) and chronic stress produce changes in brain chemistry and hormones that can increase irritability. Indeed, cortisol, the chronic stress hormone, seems to be both a cause and effect of depression – creating a vicious cycle. Additionally, both hyperarousal and addiction pathways suppress the brain’s frontal lobe, the area where mood regulation actually takes place.
5. Screen-time overloads the sensory system, fractures attention, and depletes mental reserves. Experts say that what’s often behind explosive and aggressive behavior is poor focus. When attention suffers, so does the ability to process one’s internal and external environment, so little demands become big ones. By depleting mental energy with high visual and cognitive input, screen-time contributes to low reserves. One way to temporarily “boost” depleted reserves is to become angry, so meltdowns become a coping mechanism.
6. Screen-time reduces physical activity levels and exposure to “green-time.” Research shows these factors restore attention, lower stress, and reduce aggression. Thus, time spent with electronics reduces exposure to natural mood enhancers.
In today’s world, it may seem crazy to restrict electronics so drastically. But when kids are struggling, we’re not doing them any favors by leaving electronics in place and hoping they can wind down by using electronics in “moderation.” It just doesn’t work. In contrast, by allowing the nervous system to return to a more natural state with a strict fast, we can take the first step in helping a child become calmer, stronger, and happier.
