Join the Head to Toe Challenge and help raise awareness worldwide
Join thousands worldwide in the World Thrombosis Day #HeadtoToe challenge and help raise awareness about blood clots and how they can affect the entire body. Create a short video of yourself doing the classic children’s song “Head, shoulders, knees and toes” and share it on social media and sign the WTD Pledge to prevent thrombosis and protect your health.
Blood clots are deeply connected to major chronic conditions, such as heart disease, stroke, cancer, diabetes and obesity and the #HeadtoToe challenge uses the familiar movements of the beloved children’s song to demonstrate how thrombosis affects your entire body from head to toe. When you touch each body part—your head, shoulders, knees and toes—you’re showing others how blood clot prevention protects your whole body and helps prevent deep vein thrombosis (DVT) and pulmonary embolism.

Why this matters:
Blood clots are more than just a circulatory issue. They are deeply connected to major chronic conditions such as heart disease, cancer, diabetes and obesity.
The World Thrombosis Day theme of From Head to Toe, Take Control: Prevent Thrombosis, Protect Your Health highlights these critical connections, empowering individuals to take action in preventing thrombosis and improving their overall health.
