How Does Social Media Affect Mental Health?

Introduction

Social media has become an integral part of daily life for many, with over 20.8 million Australians active on various platforms. While social media offers avenues for connection and information, there is a growing concern about its impact on mental health.

Recent data shows that more than four in ten Australian teens now experience mental health distress, with many experts linking this rise to increased social media use. This article explores the complex relationship between social media and mental health and what you can do to recognise the signs, protect your wellbeing and take control of how you engage with social platforms.

How social media affects mental health

Social media platforms are designed to keep users engaged for longer periods, often through algorithm-curated content and constant notifications. While this encourages ongoing interaction, research has shown that excessive use can lead to higher levels of loneliness and reduced overall life satisfaction.

This impact appears to be even more pronounced among young people. The Headspace National Youth Mental Health Survey found that more than half of young people (57%) believe their mental health is getting worse, with 42% identifying social media as the main reason for the decline. This growing concern raises an important question: how does social media affect teenagers’ mental health?

Studies suggest that social media use among adolescents can contribute to issues such as body image dissatisfaction, cyberbullying and frequent mood swings. High usage has also been linked to disrupted sleep, increased anxiety and symptoms of depression — all of which can affect concentration, emotional regulation and everyday life.

Social media is not all bad

Despite the risks, the effects of social media on mental health aren’t all bad. It can vary depending on how, why and how often you use it.

• Connection and community — Platforms like Instagram, Facebook and TikTok can help people feel more connected, especially during times of isolation or difficulty.

• Access to mental health resources — Many professionals and organisations share practical tips, self-care strategies and mental health education through social media.

• Quick support — It’s an easy way to discover tools, advice and coping techniques that can be applied in everyday life.

• Seeking help online — According to ReachOut, many young Australians are turning to social media to look for mental health support, showing that these platforms have become a go-to place for those in need of guidance or reassurance.

So while the negative impact of social media is real, it’s equally important to recognise its potential for good.

Tips on healthy social media habits

Understanding the impact of social media on mental health is only half the story. The other half is learning how to manage it.

Small, consistent changes in how you use social media can make a real difference. Here are a few simple ways to start:

• Mute or unfollow accounts that affect your mood — If a page makes you feel anxious, insecure or frustrated, it’s okay to step away. Your feed should support your wellbeing.

• Set screen time limits — Use your phone’s built-in tools to cap how long you spend on certain apps each day. Even 30 minutes less can improve focus and reduce stress.

• Create screen-free zones — Avoid social media during meals or before bed. Reducing screen time at night can improve sleep and help you wind down properly.

• Follow content that lifts you up — Make your feed a more positive space by following creators who focus on mental health, creativity or humour.
