Social Media Use and Effects on Adolescents

The typical teenager spends 4.8 hours on social media a day.¹ That can add up to nearly 2 full days spent scrolling each week. This prolonged exposure can lead to “curiosity traps” such as infinite scrolling, where users become absorbed in content and lose track of time.² 

With so much time spent on these platforms, social media has become deeply embedded in adolescent lifestyles. It has become a central part of daily life and is no longer just a form of entertainment. Social media can shape behaviors, habits, and overall well-being, especially for adolescents who are still in crucial stages of emotional, social, and cognitive development. 

Trends in Social Media Use³ 

How Social Media Platforms Work

Why has social media use grown so rapidly? This can be explained by the design of the platforms, which is not as random as many people believe. They are carefully designed to capture attention and maximize engagement, pulling adolescents into a cycle of constant engagement and endless doom scrolling. 

Social media platforms rely on complex algorithms powered by artificial intelligence to push out personalized content based on individual preferences. For example, the lure behind TikTok, which is especially popular among 13-18 year olds, can be explained by the use and reward theory.⁴ This theory suggests that it is human nature to seek out content that appeals to an individual's likes, preferences, and interests. All users engage with media to satisfy needs of either entertainment, social connection, or curiosity. The search engines are crafted in a way to keep filtering and adapting to those needs by analyzing user behavior. The AI system tracks and compiles data of what you watch, what you like, and what you search for to deliver tailored content that is highly engaging.

This process contributes to the creation of a “filter bubble”, where viewers are only exposed to a fraction of that content on the platform to reinforce existing preferences. As you engage more and more, the stream of personalized content stimulates the brain’s dopaminergic reward system and encourages prolonged use, keeping viewers engaged for longer periods of time. An echo chamber is created as a result of increased engagement where those same ideas are replicated from similar viewpoints. Consequently, viral content is only shared among people with similar preferences, therefore reinforcing and feeding into those same beliefs and opinions.⁴ 

How does social media impact daily life? 

Social media has several benefits and has transformed the way people interact through improved communication, self-expression, and access to information. Social media services can bring people together with this ease of communication, whether that's verbally, visually, or through interactive media.² It can foster a sense of connection and belonging, especially among teens that struggle socially in offline environments. 

However, while these platforms offer many advantages, there are several negative lifestyle changes as a result of excessive social media use. 

• Mental Health 

  • Social media platforms often create an environment that encourages comparison and can negatively impact body image. Many content creators post highly curated images with filters and editing that alter physical appearance. This sets unrealistic standards for consumers of media, especially adolescents with low self-esteem who are unaware of these digital alterations.² Many try to resemble filtered images due to pressure to meet these expectations and give in to phenomena such as “snapchat dysmorphia" which distort users’ perceptions of beauty.⁵ 

  • Depression is a major result of social media use and is associated with higher levels of screen time. Those who engage in problematic or excessive social media use are more likely to experience feelings of sadness or distress. The replacement of in-person interactions with digital communication can worsen mood and increase vulnerability to depression.³ 

• Sleep 

  • With excessive exposure to screens throughout the day from addictive social media behaviors, it is highly likely to experience disruptions in sleep pattern. Shorter bedtimes and therefore a shorter total sleep duration can change sleep habits over time and lead to more fatigue during the day.²

  • The blue light that is emitted by the devices used to consume media can inhibit the secretion of melatonin. Melatonin is the hormone responsible for sleep, meaning less melatonin can create a long term impact on the ability to fall asleep.⁴ 

• Social Behavior 

  • As adolescents spend more and more time glued to devices, face-to-face interactions become substituted by digital communication and limit the  development of essential social skills. This can lead to social isolation and impact peer relationships, family bonds, and communication abilities.² 

  • When consumed by the world of digital media, the ability to remain anonymous often gives a sense of comfort and may be misused. This creates the opportunity to engage in harmful behavior and often leads to cyberbullying. Cyberbullying negatively affects how adolescents interact in real life situations, leading to strained relationships and reduced empathy.³ 

• Physical effects 

  • Social media exposure can also influence eating habits as most adolescents are highly impressionable and vulnerable to unhealthy food advertisements and idealized diet trends. This can contribute to eating disorders including anorexia as a result of constant exposure to diet culture and unrealistic body standards. Social media exposes users to unhealthy trends such as detoxes, calorie restriction, and extreme eating behaviors. Adolescents are especially susceptible to these influences, increasing the risk for potential long-term health problems due to poor eating habits.⁵ 

  • Increased screen time and social media use is a direct contributor to sedentary behavior as well as decreased physical activity. This results in more time spent sitting and engaging with screens for prolonged periods, taking time away from outdoor activities and physical exercise.⁴

Strategies for healthy and safe social media use 

Although social media can be an entertaining and useful tool, it is important to be more mindful of the way you engage with it to protect your well-being and prevent health consequences. Here are some easy steps to establish healthier habits with social media use:

1. Switch to active use instead of passive use 

Passively scrolling without interacting can be more harmful than active engagement as it increases screen-time without purposeful interaction. Social media can be beneficial when used for self-expression or communication rather than mindless consumption.⁵

2. Follow healthy limits 

When used in moderation, social media can be a helpful tool for connection and entertainment without negatively impacting your well-being. Limiting use to 3 hours per week can significantly improve mental health and increase prosocial behavior.⁶ 

3. Set boundaries

Keep devices away from bedrooms during the night and avoid using them at least an hour before bedtime to reduce sleep disruption and support healthier sleep patterns. 

Algorithms of many social media platforms are not always effective in filtering out harmful or inappropriate content for young users. It is important to be aware of these limitations or potential risks when engaging with social media. To stay protected from harmful content while still benefiting from these platforms, here are some strategies to help keep your child safe online: 

• Avoid disclosing sensitive or personal information in posts and comments. This includes details about location, identity, health, sexuality, and racial or ethnic origins. This information can be shared without consent or misused, which many users may not be aware of. 

• Setting age restrictions can prevent early exposure to social media while adolescents are still developing and are more prone to online influence. Most platforms recommend waiting until at least 13 years of age before use. 

• Utilize built-in tools that many social media platforms offer such as Family Pairing on TikTok or applications like Google Family Link. These external tools include features to monitor activity, set time limits, and manage app usage, helping supervise activity and creating a safer online environment.⁴
