Wearing blue today signifies that you are serious about men's health, and that you encourage the men in your life to take their health seriously. Men are likely to skip hospital appointments and take more chances with their health. The three leading causes of death for American men are cancer, heart disease, and accidental deaths. The Wear BLUE Campaign provides a chance for communities to raise awareness about the importance of men's health.

National Wear BLUE Day is observed on the Friday before Father's Day.

This national day was established by the Men's Health Network.
