Three easy ways to get involved in World Autism Awareness Day

World Autism Awareness Day on April 2 is a time to shine a bright light on autism as a growing global public health priority. To commemorate this, Autism Speaks started the Light It Up Blue (#LIUB) autism awareness campaign. 

Here’s how you can get involved in #LIUB:

Pledge to Wear Blue on April 2

Join the thousands of people across the world who wear blue in honor of the millions of individuals and families affected by autism. Take the pledge today!

Get a blue bow tie like Bill Nye the Science Guy and look dapper while spreading autism awareness.

And if you want that #LIUB sign Bill Nye is holding, get yours here!

Don’t have your own blue gear? Stores have lots of autism awareness shirts and more!
