Social media can have both positive and negative effects on mental health. On one hand, it provides platforms for connection, support, and sharing experiences, which can enhance well-being. On the other hand, excessive use can lead to feelings of anxiety, depression, and low self-esteem, often due to comparison with others and cyberbullying. It's important to set boundaries around social media use, such as limiting time spent online and curating your feed to include positive influences. If you find that social media negatively affects your mood, consider taking breaks or seeking support from friends or a mental health professional. The NHS has resources to help manage this balance.
