Trapped in Your Feed: How Algorithms May Be Making Teen Mental Health Worse

Have you ever opened TikTok planning to watch one video, only to look up an hour later, wondering where the time went? It could be because of “the algorithm.”

Social media platforms are designed to keep people engaged with their site, and a big part of that comes down to algorithms. Algorithms are invisible systems that decide what videos, posts, and accounts appear in your feed each and every day. While they can help you discover new content to enjoy, they could also influence your habits and emotions more than you realize.

In this blog, we explore how algorithms shape your feed, the link between teen mental health and algorithms, and how you can take back control of your online experience.

What Are Algorithms and How Do They Shape Your Feed?

A social media “algorithm” determines what content appears in your feed. These algorithms are used by platforms like TikTok, Instagram, and YouTube to predict which posts and videos will keep you interested and scrolling on their app. But how do they work?

Every time you watch a video, like a post, leave a comment, hit the “share” button, or search for something on social media, the platform learns a little more about your personal preferences.^[1] Social media recommendation systems for teens then use this information to show you similar content in the future.

For instance, if you tend to watch videos about cute cats, video games, or tips on managing stress, you’re likely to see more content on these topics showing up in your feed. This is because the algorithm assumes that if you’ve watched or engaged with something once, you’ll probably want to see similar content again.

This can be helpful in some ways, such as by connecting you with new interests or supportive communities you may never have known about before.

However, algorithms are designed to maximise engagement rather than support your well-being. So, the platform’s aims are to keep you watching their content and coming back for more. As a result, it will feed you more of the things you watch the most.

Over time, this can create a highly personalized online world that doesn’t always reflect reality. In some ways, it may feel like living in a restricted and intense bubble where very little variety exists.

Understanding how algorithms can shape what teens see online helps explain why they are increasingly linked to mental health. Next, we take a closer look at how algorithm-driven content may affect adolescent well-being.

How Algorithms Affect Mental Health

Teen mental health and algorithms are closely linked because algorithms directly influence what young people see, think about, and engage with online. Some of the most common concerns about technology and teenage mental health involve:

• Repeated content exposure.
• Emotional manipulation.
• Social comparison.

Repeated Exposure

When adolescents watch videos on a certain topic, social media algorithms quickly show them more of the same. This creates an online environment where they see the same messages over and over.

For example, take mental health content. A teen looking up anxiety symptoms on social media might find great, reliable posts that encourage them to seek professional support.

Alternatively, with just a few clicks, a teen’s feed could unintentionally become filled with posts about panic attacks, triggering “algorithm driven anxiety.” And over time, they might start over-focusing on their own feelings or misinterpreting everyday stress as a medical condition.

But teens aren’t doing this on purpose – often, they’re just trying to understand difficult emotions. The real problem is that these highly personal feeds and recommendations make it easier to blur the line between learning about a mental health condition and overly identifying with it.

Social Media Emotional Manipulation

Emotional manipulation is also linked with teen mental health and algorithms. This is because content that triggers strong emotional reactions often performs well online. It grabs people’s attention and encourages them to engage with the content by liking, sharing, or leaving a comment.^[1]

As a result, social media algorithms may end up promoting content that is:

• Dramatic.
• Upsetting.
• Emotionally intense.

Although this content may keep adolescents tuned in, it can also leave them feeling overwhelmed or emotionally drained.^[2][3]

Personalized content and teen anxiety can then become closely linked. And the more they engage with these posts and videos, the more likely the algorithm is to show them even more.

Social Comparison

Social media feeds are frequently filled with carefully edited images and seemingly “perfect” lifestyles. Yet being constantly exposed to these posts might leave teens feeling like everyone else is happier, more successful, or more attractive than they are.

Research suggests this type of social comparison may contribute to:^[4][5]

• Lower self-esteem.
• Body image concerns.
• Emotional distress.

When these factors are put together, they show the growing digital influence on teen mental health and why experts are paying extra attention to how algorithms shape their online experiences.

Doomscrolling, Overstimulation, and Social Media Addiction

The link between teen mental health and algorithms goes beyond what teens see online and how they feel while there – they also influence how long adolescents keep watching. On top of this, features like autoplay and push notifications make it easy to keep scrolling for longer than intended, potentially leading to doomscrolling, overstimulation, and even addiction.

Teen Doomscrolling and Mental Health

“Doomscrolling” refers to repeatedly scrolling through negative, upsetting, or emotionally intense content for long periods of time.^[6]

It’s not something that people set out to do, but a teen might watch one stressful video and quickly find themselves pulled down a rabbit hole and watching dozens more. Over time, this can contribute to:^[7]

• Stress.
• Overwhelm.
• Irritability.
• Emotional exhaustion.

Overstimulation

Teen screen time and mental health are also connected. This is because many teenagers use social media late into the evening, often right before bed. However, notifications and endless content may make it harder to switch off mentally, leading to poorer sleep, which can then affect the next day’s:

• Mood.
• Concentration.
• Energy levels.

Social Media Addiction in Adolescents

While not every teen develops unhealthy online habits, some may find it difficult to cut back on social media, even if it’s affecting them negatively. For example, some adolescents may feel the need to constantly check notifications or feel uncomfortable when they don’t have their devices close to hand.

Researchers have also raised concerns about social media addiction. In particular, studies have found that TikTok may have a higher addictive potential than other social media platforms due to its algorithm, which could lead to problematic online behaviors.^[3]

Knowing how to ensure your digital use remains healthy is an important part of staying safe online.

How to “Hack” the Algorithm and Protect Your Mental Health

The good news is that algorithms are not completely in control of what you see online. Making even small changes in your online habits can influence what shows up in your feed and help create a healthier digital experience for you.

Here are some suggestions for how you can take back control of your feed:

• Curate your feed: Unfollow, mute, or block accounts that leave you feeling anxious or low, and replace them with creators whose content feels supportive or uplifting.

• Use the “Not Interested” feature: Many platforms allow you to tell the algorithm when you don’t want to see certain content. Using these tools can make a difference to what you see in your feed over time.

• Take regular breaks: Time away from social media can help reduce overstimulation.

• Set screen-time boundaries: You might choose to set phone-free times during the day, especially before bedtime, to reduce overstimulation.

• Check in with yourself: Notice how different types of content affect your mood after scrolling.

• Fact-check mental health content: If you’re concerned about your mental health, only use trusted sources for advice and speak with a qualified professional rather than relying solely on social media for support.

• Make time for real-world connections: Remember to spend time with trusted friends, family, and supportive adults offline.

In a nutshell, healthy social media use is about learning how to use these platforms in ways that support your well-being.
