How do I know if social media is harming my teenager's mental health rather than just being a normal part of life?

Watch for patterns rather than one bad day: disrupted sleep, anxiety or low mood after scrolling, withdrawal from offline activities, or distress when they can't check their phone. Encourage them to notice how different apps make them feel. If their wellbeing is clearly suffering, talk to your GP. Childline (0800 1111) and the NHS also offer support for young people's mental health.

Is it reasonable to ask my 15 year old to take breaks from social media?

Yes, and it works best framed as a shared habit rather than a punishment. Phone-free mealtimes, no screens in the hour before bed, and device-free family time benefit everyone, and modelling it yourself carries far more weight than rules alone. Help them set their own boundaries too, like turning off notifications, so they build self-regulation that lasts beyond your supervision.

Healthy Social Media Habits for 14–16 Year Olds

Practical guidance on developing a balanced, healthy relationship with social media during the mid-teenage years.

Social media is deeply embedded in teenage life, and asking a 14–16 year old to avoid it entirely is rarely realistic. Instead, this page focuses on building healthy habits — understanding how algorithms work, managing screen time, recognising the impact on mental health, and curating a positive online experience.

Understanding How Algorithms Work

Help your teenager understand that social media feeds are not random — algorithms are designed to maximise engagement by showing content that triggers strong emotional reactions. This means negative or sensational content is often promoted above neutral or positive content. Knowing this can help teenagers view their feeds more critically.

Managing the Mental Health Impact

Research links heavy social media use to increased anxiety, depression, and poor body image in teenagers. Encourage your teen to notice how they feel after using different platforms and to unfollow accounts that make them feel worse. Suggest regular social media breaks and support them in finding offline activities that boost their wellbeing.

Building a Positive Feed

Encourage your teenager to actively curate their social media experience by following accounts that inspire, educate, or entertain them in a positive way. Show them how to use platform tools to mark content as 'not interested' and block or mute accounts that post harmful material. A consciously curated feed is a healthier feed.
