In the silent hours of the night, as the glow of a smartphone screen casts shadows across a bedroom in Lagos, a different kind of loneliness begins to bloom. It’s not the loneliness of being physically alone—but that creeping, invisible ache that comes from scrolling endlessly through filtered lives, curated smiles, and achievements that seem just out of reach.

Recent research has revealed something staggering: Gen Z is the first generation in human history to be exposed to, process, and emotionally engage with this much information this fast. From world news to TikTok trends, from climate anxiety to celebrity gossip, their minds are in a constant state of stimulation. The average Gen Z, and indeed many millennials, consume hours of content every day—much of it visual, curated, and emotionally charged. And it’s beginning to take a toll.

This is the new normal. And across Nigeria, it is quietly eroding the mental health of millions.

Nigeria ranks among the top countries in Africa in terms of smartphone and internet usage, especially among the youth. With nearly 100 million internet users—most of them active on social media—this widespread connectivity is both a strength and a growing concern.

A 2022 UNICEF report revealed that nearly 1 in 6 Nigerian adolescents showed signs of a mental health condition, with social media frequently mentioned as a contributing stressor. In Nigeria, where economic hardship, social expectations, and cultural stigma already make mental wellness a delicate subject, social media has added a complex, often invisible layer to the burden. The very platforms that promise community and creativity are becoming conduits for isolation, comparison, and despair.

Mental health professionals, educators, and even parents are noticing a shift: attention spans are shrinking, self-worth is now measured in likes, and digital exhaustion is becoming a silent epidemic. Yet, the warning signs—like the phone screens—often go unnoticed in the noise.

As the country embraces digital transformation, a critical question remains: at what cost to the minds of its youth?

Stigma, Silence, and a System Under Pressure

One of the greatest challenges facing Nigeria’s mental health crisis is not technology—it’s silence. Mental illness still carries a heavy stigma, often dismissed as weakness, spiritual attack, or attention-seeking. Many suffer in silence, afraid to speak out.

Despite the growing need, Nigeria has less than 300 practicing psychiatrists for a population of over 200 million. Therapy is often unaffordable. Mental health services are concentrated in urban areas, leaving rural communities with little to no support. And while social media contributes to the problem, it rarely provides solutions—unless actively redirected to do so.

Mental Illnesses Linked to Social Media

1. Depression
   
   

   • Numerous studies have found a strong correlation between prolonged social media use and depression. Social comparison, cyberbullying, and the fear of missing out (FOMO) often lead users to feel inadequate or left out.
     
     

   • Instagram and Snapchat, where people tend to post idealized versions of their lives, are particularly associated with depressive symptoms among youth.

According to the World Health Organization (WHO), over 7 million Nigerians suffer from depression, making it the most common mental illness in the country.

2. Anxiety Disorders
   
   

   • Constant notifications, the pressure to respond quickly, and fear of missing out can heighten anxiety levels. People may become anxious when they are not connected or feel they are being ignored online.
     
     

   • Social media anxiety disorder is becoming increasingly recognized—a subtype of social anxiety related specifically to digital interaction.

• An estimated 4 million Nigerians experience anxiety disorders.
  
  

3. Sleep Disorders
   
   

   • The “doom-scrolling” habit, especially at night, affects sleep patterns. The blue light emitted by screens interferes with melatonin production, delaying sleep onset and reducing sleep quality.
     
     

   • Poor sleep is directly linked to increased risk for depression and anxiety.
     
     

4. Body Dysmorphic Disorder (BDD) and Eating Disorders
   
   

   • Exposure to heavily filtered or edited images often leads to unrealistic beauty standards. Many young Nigerians report dissatisfaction with their appearance due to comparing themselves with influencers and celebrities.
     
     

   • This can lead to body dysmorphia or eating disorders such as anorexia or bulimia.
     
     

5. Addiction and Attention Disorders
   
   

   • Social media is designed to be addictive. The dopamine rush from likes, comments, and shares keeps users hooked. This compulsive use can interfere with daily responsibilities, causing distress and functional impairment.
     
     

   • Excessive social media use has also been linked to reduced attention span and difficulty concentrating, especially among students.
     
     

6. Cyberbullying and PTSD
   
   

   • Victims of online harassment or revenge porn may experience trauma symptoms similar to post-traumatic stress disorder (PTSD). In extreme cases, this has led to suicide among Nigerian teens and young adults.

• Nigeria has one of the highest suicide rates in Africa, with social isolation and cyberbullying cited among contributing factors.

Nigeria’s youth are facing a silent mental health crisis, intensified by the constant pressure and comparison fueled by social media. Behind every curated post lies a growing burden—depression, anxiety, and isolation. With limited access to mental health care and deep-rooted stigma, many suffer in silence. To protect the minds shaping Nigeria’s future, we must break that silence, spark honest conversations, and create systems that support digital wellness alongside digital growth.
