Smartphones have become an inseparable part of modern life, revolutionizing communication, work, and entertainment. However, excessive smartphone use (ESU) has been linked to various negative consequences, including addiction-like behaviors, impaired mental health, and diminished attention spans. Recent studies suggest that smartphone-related cues can trigger neural responses similar to those seen in substance addiction, reinforcing compulsive usage patterns. Understanding the effects of smartphone restriction on cue-related neural activity can provide valuable insights into developing interventions for individuals struggling with ESU.
The Role of Cue Reactivity in Smartphone Use
Cue reactivity (CR) refers to the brain’s response to stimuli associated with a habitual or addictive behavior. In the case of smartphone use, cues may include notification sounds, phone screens lighting up, or simply seeing a smartphone in one’s environment. These cues can activate reward-related brain regions, reinforcing the compulsive urge to check the device.
Research has shown that individuals with excessive smartphone use exhibit heightened neural responses to smartphone-related cues, similar to those observed in substance addiction. This heightened sensitivity may contribute to difficulty in controlling smartphone usage, leading to a cycle of compulsive checking and craving.
Investigating Neural Activity Changes Through Smartphone Restriction
To better understand how short-term smartphone restriction influences brain activity, researchers conducted a study using functional MRI (fMRI) to measure changes in cue-related neural responses over 72 hours of smartphone abstinence. The study involved 25 young adults who were regular smartphone users.

Study Design and Methods
- Participants were instructed to refrain from using their smartphones for 72 hours.
- A cue-reactivity task was designed, where participants were exposed to images of smartphones (both active and inactive) as well as neutral objects.
- Functional MRI scans were conducted before and after the restriction period to analyze changes in brain activity.
- Psychometric assessments were used to measure craving, self-control, and emotional responses associated with smartphone use.
Key Findings: How the Brain Adapts to Smartphone Restriction
1. Reduced Activation in the Reward System
One of the most striking findings was a significant reduction in activity in the nucleus accumbens and anterior cingulate cortex after 72 hours of smartphone restriction. These brain regions are heavily involved in reward processing and habit formation.
- The nucleus accumbens is associated with motivation and reinforcement learning. High activation in this area suggests strong craving and compulsive behavior.
- The anterior cingulate cortex plays a role in decision-making and impulse control. Reduced activity here indicates that participants may have experienced less compulsion to check their smartphones.
These findings suggest that even a short break from smartphone use can lead to neuroplasticity, allowing the brain to become less reactive to smartphone-related cues.
2. Alterations in Dopamine and Serotonin-Linked Activity
Further analysis using neurotransmitter probability maps revealed that activity changes in the reward system were closely linked to dopamine and serotonin receptor probabilities.
- Dopamine is a key neurotransmitter in reward-seeking behavior and addiction.
- Serotonin is involved in mood regulation and impulse control.
The findings suggest that smartphone restriction may influence neurochemical processes that drive compulsive behaviors. This could explain why some people feel withdrawal-like symptoms, including restlessness and anxiety, when they suddenly stop using their phones.
3. Increased Engagement of the Parietal Cortex
Another notable result was the increased activity in the parietal cortex, a region associated with attentional control and sensory processing.
- This suggests that participants became more aware of their environment and less preoccupied with smartphone-related distractions.
- Heightened parietal cortex activity was correlated with reduced craving scores, indicating improved cognitive control over impulsive smartphone use.
This supports the idea that limiting smartphone use can enhance focus and attentional regulation, reducing dependency on digital devices.
4. Reduced Compulsive Checking Behavior
Behavioral assessments showed that participants experienced a significant decrease in the urge to check their smartphones over time. This aligns with the observed neural changes in reward sensitivity and impulse control.
Participants also reported improvements in:
- Sleep quality: Reduced exposure to blue light and nighttime scrolling led to better sleep patterns.
- Social interactions: Without constant phone distractions, participants engaged more with people around them.
- Mental well-being: Several individuals noted feeling less anxious and more present in their daily activities.
Implications for Smartphone Addiction and Digital Detox Strategies
The findings of this study have significant implications for individuals struggling with excessive smartphone use. While a complete break from smartphones may not be feasible for everyone, implementing digital detox strategies can help manage usage and mitigate negative effects.
1. Scheduled Smartphone Breaks
- Taking regular breaks from smartphone use, even for a few hours a day, can help reset neural responses to digital cues.
- Setting specific times for checking messages rather than responding to every notification can reduce compulsive checking.
2. Mindful Technology Use
- Practicing conscious smartphone use by turning off unnecessary notifications and using grayscale mode can help decrease reliance on digital stimuli.
- Engaging in non-digital hobbies, such as reading, exercise, or meditation, can strengthen attention control and reduce smartphone dependency.
3. Sleep Hygiene and Nighttime Restrictions
- Avoiding smartphone use one hour before bed can improve sleep quality by preventing blue light exposure.
- Using do not disturb or airplane mode at night can minimize the temptation to check notifications.
4. Awareness Campaigns and Education
- Schools, workplaces, and mental health professionals can promote awareness of the impact of excessive smartphone use on brain function.
- Implementing digital wellness programs can encourage balanced technology use.

Conclusion: How Smartphone Restriction Reshapes the Brain
The study provides compelling evidence that even a short period of smartphone restriction can lead to measurable changes in brain activity. The observed reductions in reward-related neural responses, coupled with increased attentional control, suggest that limiting smartphone use can promote cognitive flexibility, impulse control, and overall mental well-being.
As smartphone addiction continues to be a growing concern, understanding the neurological basis of cue-reactivity and digital dependency is crucial. These findings highlight the importance of incorporating healthy technology habits to ensure that smartphones remain tools for convenience rather than sources of compulsive behavior.
By making small adjustments in smartphone usage, individuals can foster better focus, improved mental clarity, and greater overall life satisfaction. So, why not start with a 72-hour break and see how your brain adapts?
DWTS fans blast Gene Simmons for ‘cringey’ comments: ‘worst guest judge’
Fans of Dancing with the Stars are expressing their shock over Gene Simmons using his position as a guest judge to “sexualize women.”
The 75-year-old KISS frontman, known for his larger-than-life stage presence and persona, joined the show to critique the contestants on Hair Metal Night as they danced to iconic rock anthems from the 1980s.
But audiences are now demanding the network “issue an apology” for “putting a creep on the show,” and for providing him a platform to voice his “cringe-worthy” and “sexist” comments.
On the Tuesday, October 9 episode of Dancing with the Stars, KISS rocker Gene Simmons raised quite a few eyebrows with his controversial guest appearance.
As part of the show’s Hair Metal Night, Simmons joined regular judges Carrie Ann Inaba, Derek Hough, and Bruno Tonioli to critique the celebrity dancers.
Despite the high energy of the nostalgia-filled performance set to hits like Cherry Pie and Rock You Like a Hurricane, Simmons’ sexually suggestive remarks overshadowed the night for many fans.
While his rock persona has long been associated with pushing boundaries, many felt his behavior wasn’t suited for the lighthearted nature of the competition series.
Throughout the episode, Simmons, 75, made several remarks that focused less on the dancing and more on the female dancer’s looks, which many viewers call “creepy.”
After former NFL wide receiver Danny Amendola and Witney Carson hit the dance floor, “The Demon” said he couldn’t figure out who was more “hot hot hot.”
“Danny, I’m telling you, you’re right next to somebody – one of the most beautiful women on the planet. She makes you look good. Buddy, you gotta hit the gym. You gotta get in there,” added Simmons.
And then, referring to Emma Slater who was dancing with actor Reginald VelJohnson dancer, he said: “You’ve got a beautiful woman right beside you, who can twist it and turn it, and knows how to move it and, you know, all that.”
The rock legend also had words for VelJohnson. “I wanna tell you, as a guy that’s been on the stage for half a century around the world, I’m kind of a big deal, Reggie,” Simmons said. “It’s all in the attitude and you’ve got something in that beautiful face, they love you!”
Perhaps one of his cringiest remarks was directed to actor-singer Chandler Kinney. Explaining that her moves “fogged up” his glasses, Simmons removed his dark shades and said, “You moved me, not just with your gyrations and so on, but your beautiful face and how you were into the emotion of it – top to bottom.”
He did however offer one relevant opinion to Kinney when he praised her talents, noting that she has a “big future” ahead of her.
Social media quickly filled with backlash, with many expressing their discomfort and frustration. Some viewers even went as far as to call him the “worst guest judge” in the show’s 33-season run.
“I usually like Gene Simmons and think he’s funny. But that was not the case as a guest judge. Very inappropriate and just not helpful,” writes one cyber fan on the DWTS Facebook site.
A second shares, “It was uncomfortable for us watching, can’t even imagine how the women felt. And he wasn’t scoring dances, he was just giving out random numbers.”
Gene was a bust! His comments and feedback were inappropriate along with the scores.”
A third critic adds, “His comments on all the girls was cringe!”
Another user calls Simmons “vulgar” and says he’s “the worst judge ever
Meanwhile, other online citizens are calling out ABC and Disney+, suggesting the network and streaming service apologize to fans of DWTS.
“Y’all owe the biggest apology to your fanbase (which is primarily women) & the dancers for putting that creep on your show and allowing for him to sexualize them on live TV,” one netizen writes on Facebook.
A second pens, “They need to apologize for having Gene Simmons. It was cringe-worthy. His comments were sexist, and he was just awful.”
“But they had a felon on the show this season,” adds another user, who’s referring to Anna Delvey (Sorokin), the convicted fraudster who sparked a lot of controversy with her appearance on September 17, the first episode of the DWTS season.
