Social Media and Mental Health
Comparison, FOMO, and Sleep

Social media can shape mood, sleep, attention, friendships, and self-image, especially during the teen years when the brain is still developing social and emotional skills. Researchers such as Jean Twenge and Jonathan Haidt have argued that rising smartphone and social media use may be connected to increases in teen anxiety and depression. Other scientists emphasize that the evidence is mixed and that not every teen is affected in the same way. Understanding both risks and benefits helps students make healthier choices instead of treating all screen time as either good or bad.
Heavy use can increase exposure to comparison, fear of missing out, cyberbullying, endless scrolling, and sleep disruption. At the same time, social media can provide community, creative expression, identity exploration, and support for people who feel isolated offline. A key scientific challenge is separating correlation from causation, because teens who are already stressed may use social media more, while heavy use may also worsen stress for some users. Healthy use depends on timing, content, purpose, sleep protection, and whether online activity strengthens or replaces real relationships.
Key Facts
- Correlation means two variables change together, but it does not prove that one causes the other.
- Risk is often higher when social media use is passive, late at night, conflict-filled, or based on appearance comparison.
- Displacement effect: Time online can reduce time for sleep, exercise, homework, and face-to-face relationships.
- Sleep balance formula: Healthy day = enough sleep + schoolwork + movement + real social connection + screen limits.
- Mood tracking formula: Mood change = mood after use - mood before use.
- A healthier goal is intentional use, where purpose, time limit, and emotional effect are checked before and after going online.
Vocabulary
- FOMO
- FOMO, or fear of missing out, is the anxious feeling that others are having rewarding experiences without you.
- Doomscrolling
- Doomscrolling is the habit of repeatedly consuming negative online content even when it worsens mood or stress.
- Social comparison
- Social comparison is judging yourself by comparing your life, body, success, or popularity with other people.
- Correlation
- Correlation is a statistical relationship in which two variables tend to change together without proving cause and effect.
- Cyberbullying
- Cyberbullying is repeated harmful behavior through digital tools, such as harassment, humiliation, threats, or exclusion online.
Common Mistakes to Avoid
- Assuming social media is always harmful, because the effects depend on the person, content, timing, and purpose of use.
- Treating correlation as proof of causation, because a study showing heavy users have more anxiety does not by itself prove social media caused the anxiety.
- Counting all screen time the same way, because video chatting with a supportive friend is different from late-night comparison scrolling.
- Trying to improve mental health only by deleting apps, because sleep, exercise, offline support, therapy, and family routines may also be needed.
Practice Questions
- 1 A student rates their mood as 7 out of 10 before using social media and 4 out of 10 after 45 minutes of scrolling. Using mood change = mood after use - mood before use, what is the mood change, and what might this suggest?
- 2 A teen spends 3.5 hours per day on social media. They set a goal to reduce this by 40 percent. How many hours per day would they use social media after the reduction?
- 3 Two students both spend 2 hours per day on social media. One uses it to message close friends and join a supportive art community, while the other uses it mostly for appearance comparison and doomscrolling before bed. Explain why their mental health outcomes might differ.
