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.
Always more often children 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 struggle academically and socially.
At some point, a child with these symptoms may be given a mental health diagnosis such as major depression, bipolar disorder, or ADHD, and offered corresponding treatments, including therapy and medication.
What’s happening?
Both parents and clinicians may be “barking up the wrong tree.” That is, they’re trying to treat what looks like a textbook case of mental disorder, but failing to rule out and address the most common environmental cause of such symptoms—everyday use of electronics!
What to do?
Only successfully treating a the child with mood dysregulation today requires methodically eliminating all electronics use for several weeks—an “electronics 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.
Here’s a look at six physiological mechanisms that explain electronics’ the 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 gaming releases so much dopamine—the “feel-good” chemical—that on a brain scan it looks the same as cocaine use. But when reward pathways are overused, they become less sensitive and more and more stimulation is needed to experience a pleasure. Meanwhile, dopamine is also critical for focus and motivation, so needless to say, even small changes in dopamine sensitivity can wreak havoc on how well a the 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. 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 are reluctant to restrict electronics use in a child’s bedroom because they worry the child will enter a state of despair—but removing light-at-night is protective.
4. Screen time induces stress reactions.
Both acute stress (fight-or-flight) and chronic stress produces changes in brain chemistry and hormones that can increase irritability. Indeed, cortisol, the chronic stress hormone, seems to be both a cause and an 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 that time outdoors, especially interacting with nature, can restore attention, lower stress, and reduce aggression. Thus, time spent with electronics reduces exposure to natural mood enhancers.
