The National Association Against Sitting (NAAS) is a public-health education nonprofit dedicated to reducing prolonged sitting and sedentary behavior. The organization approaches sedentary behavior as a public-health and environmental issue shaped by modern work, education, and daily life.
The mission of the National Association Against Sitting is to reduce prolonged sitting and sedentary behavior through public-health education, community programs, awareness initiatives, and evidence informed outreach.
The organization works to improve understanding of sedentary behavior and its health impacts by providing accessible educational resources, supporting community based initiatives, and promoting practical approaches that help individuals and organizations sit less and incorporate healthier movement patterns into daily life.
As daily routines have become increasingly seated at work, during transportation, and in front of screens —— prolonged sitting has emerged as a widespread but often overlooked public-health concern. Despite growing research, sedentary behavior is rarely discussed clearly or consistently outside of fitness or individual responsibility frameworks.
NAAS exists to address this gap through education, research translation, and evidence informed guidance focused on everyday environments.
Our purpose is to help individuals and organizations better understand how sedentary patterns develop, why they matter from a public-health perspective, and what practical, responsible strategies can reduce prolonged sitting over time.
We focus on awareness, structure, and systems —— not blame, trends, or quick fixes.
We approach sedentary behavior as a public-health and design issue, not a personal failure or fitness trend.
Prolonged sitting is shaped by workplaces, infrastructure, technology, and social norms. Addressing it requires thoughtful education and environmental awareness rather than mandates, fear based messaging, or one-size-fits-all solutions.
Our work emphasizes clarity, neutrality, and long-term adoption.
National Association Against Sitting (NAAS) provides education and guidance to support healthier everyday environments through:
• Clear, accessible information about sedentary behavior and movement health
• Translation of research into practical, evidence informed guidance
• Voluntary standards and best practices for organizations and institutions
