Bad Influence

How the Internet Hijacked Our Health

'Your definitive guide to separating medical facts from online fiction.' Adam Kay, author of This is Going to Hurt

'This superb book is an essential guide to the wild world of internet health.' Chris van Tulleken, author of Ultra-Processed People

Need to focus? Want to lose weight? Build muscle? Get pregnant? Advice is just a click away.
