Social media is a major part of modern life. Most of us can't imagine not using it, and it's unrealistic to assume that's even possible.

Platforms like Instagram, Twitter and Facebook haven't been around long, but they have already made far-reaching impacts on our health and wellbeing.

By the end, you'll be armed with knowledge and tactics, so you can take back control and make social media work for you.
