Social Media and Mental Health

By: Dr. Tariq Jagnarine

Over the years, both as a clinician and as someone working in global and public health leadership, I have become increasingly concerned about something often overlooked in modern healthcare conversations.

Many people are mentally exhausted.

Not only from work, family responsibilities, or financial pressures, but from the constant emotional and psychological stimulation that comes with modern digital life and social media.

As healthcare professionals, we traditionally focus heavily on physical diseases such as hypertension, diabetes, heart disease, infections, and cancer. But increasingly, I believe we are now witnessing another major public health challenge quietly unfolding in front of us: chronic mental overload.

And for many people, social media plays a larger role than they realize.

Research increasingly demonstrates associations between excessive social media use and poorer mental health outcomes, particularly anxiety, depression, sleep disturbances, low self-esteem, and emotional burnout among adolescents and young adults (Keles, McCrae & Grealish, 2020; APA, 2023).

What I Am Seeing More Frequently

In clinical practice and public health work, I increasingly encounter people struggling with:

• Anxiety 

• Burnout 

• Sleep deprivation 

• Poor concentration 

• Emotional fatigue 

• Low self-esteem 

• Chronic stress 

• Feelings of inadequacy 

• Loneliness despite constant online interaction 

What is striking is that many individuals do not immediately recognize how much their digital habits may be contributing to these feelings. We now live in a world where the brain rarely gets an opportunity to fully rest. From the moment many people wake up, they are exposed to:

• Notifications 

• News 

• Arguments 

• Viral content 

• Distressing world events 

• Financial comparisons 

• Beauty standards 

• Career pressures 

• Online opinions 

• Constant stimulation 

The mind remains “on” almost continuously.

Studies suggest that prolonged exposure to digital stimulation may contribute to heightened stress responses, impaired concentration, reduced productivity, and emotional fatigue (Twenge & Campbell, 2018).

The Culture of Comparison

One of the most concerning patterns I observe is the emotional effect of constant comparison.

Social media often creates the illusion that everyone else is:

• More successful 

• Happier 

• Wealthier 

• More attractive 

• More fulfilled 

Yet as clinicians, we know reality is often far more complicated. Behind many polished online images are individuals silently dealing with:

• Depression 

• Anxiety 

• Family problems 

• Financial struggles 

• Burnout 

• Relationship challenges 

• Emotional isolation 

One thing I have reflected on personally is how dangerous it becomes when people begin to measure their self-worth byonline validation.

Likes, comments, followers, and views can never truly define a person’s value.

Research on social comparison theory has shown that repeated exposure to idealized online content may negatively affect self-esteem, body image, and emotional well-being, particularly among younger populations (Vogel et al., 2014).

The Psychological Impact on Young People

As a global health professional, I am especially concerned about the effect social media is having on adolescents and young adults. This generation is growing up in an environment where:

• Validation is increasingly external 

• Appearance is constantly scrutinized 

• Comparison never stops 

• Online criticism can become relentless 

• Unrealistic beauty and lifestyle standards dominate 

Many young people now feel pressure not only to succeed in real life, but to appear successful online at all times.

This creates enormous emotional pressure during already vulnerable stages of psychological development.

Globally, studies increasingly show associations between excessive social media use and:

• Depression 

• Anxiety disorders 

• Self-esteem issues 

• Eating disorders 

• Sleep disturbances 

• Social withdrawal 

And these concerns are not limited to high-income countries. We are seeing similar patterns emerging across the Caribbean and developing regions as digital access expands.

The World Health Organization has also highlighted growing global concerns surrounding adolescent mental health, screen exposure, cyberbullying, and digital wellbeing (WHO, 2022).

The Brain Was Never Designed for Constant Stimulation

From a neuroscience and behavioral perspective, modern social media platforms are designed to maintain engagement.Every notification, like, comment, and video recommendation triggers dopamine release within the brain’s reward system.Over time, many people unconsciously develop compulsive behaviors such as:

• Constant scrolling 

• Repeatedly checking phones 

• Difficulty disconnecting 

• Feeling anxious when offline 

• Difficulty focusing on real-world tasks 

I think many people underestimate how psychologically draining this can become over months and years.

We often recharge our devices daily, yet neglect our own mental recovery.

Emerging neuroscience research suggests that compulsive digital engagement activates reward pathways similar to other behavioral addictions, contributing to dependency patterns and reduced attention control (Montag & Walla, 2016).

Social Media Is Not Entirely Negative

At the same time, I do not believe social media itself is inherently harmful. In fact, many of the public health messages I share today reach thousands of people precisely because of these platforms. Social media has helped:

• Spread health awareness 

• Improve access to information 

• Build communities 

• Support advocacy 

• Connect families and friends globally 

• Amplify important public health issues 

The issue is not social media alone.

The issue is balance, boundaries, intentional use, and protecting mental well-being in an environment designed to constantly demand our attention.

During public health emergencies such as COVID-19, digital platforms also played important roles in health communication, education, and community mobilization (Cinelli et al., 2020).

Personal Reflection

Personally, one of the biggest lessons I have learned is the importance of protecting quiet moments. Some of the healthiest things we can do for our minds are often the simplest:

• Spending uninterrupted time with loved ones 

• Walking outdoors 

• Exercising 

• Sleeping properly 

• Having meaningful conversations 

• Disconnecting from screens 

• Reflecting quietly 

• Being present in the moment 

As clinicians, we often advise patients to monitor blood pressure, cholesterol, blood sugar, and physical health. But I believe we also need to start asking ourselves:

• When last did I truly rest mentally? 

• When last did I disconnect from constant stimulation? 

• When last did I spend time fully present with myself or my family? 

Mental health is not only about the absence of illness. It is also about emotional balance, rest, peace, and meaningful human connection.

Healthy Social Media Habits

Simple steps can protect mental wellbeing:

• Limit screen time

• Avoid scrolling before bed

• Take regular social media breaksHealth,

• Unfollow toxic accounts

• Prioritize real-life relationships

• Spend more time outdoors

• Exercise regularly

• Protect personal privacy online

• Avoid comparing yourself to others

Social media is one of the most powerful tools of our generation. It can educate, inspire, connect, and empower. But without boundaries, it can also quietly contribute to emotional exhaustion, anxiety, insecurity, and disconnection from real life.

Your worth is not determined by online validation.

Protect your peace.

Protect your mind.

Take breaks when needed.

And remember that sometimes the healthiest thing you can do is step away from the screen and reconnect with yourself, your family, and the real world around you.
