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?
The fascinating and tragic story of Mary Ann Bevan
The story of Mary Ann Bevan, who was considered ‘The ugliest woman in the world,’ starts in the 19th century, a dark period of the American culture when ‘freak shows,’ traveling circuses showing people with certain deformities and disabilities, were at the peak of their popularity.
Today, it is highly unacceptable to treat people with disabilities with disrespect, but back in the day, no one believed it was morally wrong to dub them freaks.
Mary Ann Bevan was born on December 20, 1874, in Plaistow, East London, United Kingdom. She grew up to become a nurse and was respected by the society. On top of that, she was a very attractive woman who was offered many possibilities.
In 1902, Mary met the love of her life, a man named Thomas Bevan. The two married and welcomed four children together, but their happiness didn’t last long. After 14 years, Thomas passed away, leaving Mary heartbroken.
Her life became difficult as she was left to take care and provide for her children all by herself.
Unfortunately, around the time she turned 32, Mary started experiencing strange symptoms. Her face started changing gradually and she didn’t know what was happening or what caused that change which impacted her both psychologically and financially. Mary’s bones grew big, and her face became deformed. As a result, she lost her job and was unable to provide for her children any longer.
Back in the day, no one could diagnose her, but this poor woman suffered from acromegaly, a hormonal disorder that develops when the pituitary gland produces too much growth hormone during adulthood, when a change in height doesn’t occur. Instead, the increase in bone size is limited to the bones of the hands, feet and face.
Today, a lot more is knows about this condition and there are ways to keep it under control, which wasn’t the case during the time Mary lived.
Crushed, heartbroken, and poor, this woman saw an ad one day which read, “Wanted: Ugliest woman. Nothing repulsive, maimed or disfigured. Good pay guaranteed, and long engagement for successful applicant. Send recent photograph.”
No matter how awful she felt about this ‘job,’ she saw no way out of her situation. She simply needed to do anything in order to feed her children. Above all, she was a mother.
Mary answered the ad and she was soon contacted by the circus’ agent, a man named Claude Bartram, who later shared Mary’s story.
“She was not repulsive at all. She had the kind of face one usually finds in a giant, a powerful, masculine jaw, prominent cheek-bones, nose and forehead, but she was unblemished, healthy and strong. She told me she did not like the idea of placing herself on exhibition, she was shy and did not want to be separated from her children,” Bartram said, according to Daily Star.
“I told her she would earn £10 per week for a year, travelling expenses and all the money from the sale of picture postcards of herself, so she could provide for the education of her children.”

In no time, magazines were filled with Mary Ann’s photos and everyone recognized her as ‘the ugliest woman on Earth.’
Her popularity brought her to the Dreamland Circus in Coney Island, New York, one of the most famous circuses there were. Mary Ann became an attraction, but then a doctor named Harvey Cushing, a leading neurosurgeon, spotted her and knew there was more behind ger huge face that he wanted to explore thoroughly.
“This unfortunate woman who sits in the sideshow of Ringling Brothers ‘between Fat Lady and Armless Wonder’ and ‘affects white lace hats, woollen mittens and high laced shoes’ has a story which is far from mirth-provoking.
“She, previously a vigorous and good-looking young woman, has become the victim of a disease known as acromegaly,” he wrote in a letter to Time magazine.
Mary Ann spent her life working at the circus and she was reported to have earned a small fortune which enabled her to send her children back to England where they attended boarding schools.
She endured a lot, but she did it all for her children.
Mary Ann died at the age of 59 of natural causes. Her final wish was to be buried in her homeland, England, and her children fulfilled her wish. She is resting at the Ladywell and Brockley Cemetery in South London.
This woman’s sad, yet fascinating life story speaks of the mother’s love for her children more than anything else.
