Your Health

About Us

In January 2022, Because Health merged with the non-profit, the Center for Environmental Health. CEH is a 25-year-old non-profit based in Oakland, CA, leading the nationwide effort to protect people from toxic chemicals. Like us, they believe that our air, water, food, and consumer products should be free of harmful and untested chemicals.

From 2018-2022, Because Health was a non-profit environmental health site that was a part of the Collaborative on Health and the Environment and founded by Karen Wang, PhD| MSc. Because Health brings you everything you need to know about how the places we live, work, and play impact our health. Through a combination of science-based tips, guides, and expert advice, it’s our mission to show people simple ways to create a healthier future for themselves and their communities.

This is a site for people who care about their wellness and health, and recognize that pollution of our air, water, and soil, toxic chemicals in our products, and other environmental risks like climate change, are just as important as working out and eating right. We do the research, read the reports, interview the experts, find the safe products, and make it interesting so that you can live your best life. We are a place for real people, who don’t have time to DIY everything, but want to make informed choices and advocate for the things they care about, because health.


To improve individual and collective health by sharing knowledge, providing resources, and building a young community around a shared concern for how environmental risks can impact health.


A world where all people live free from environmental risks that harm human health


We embrace what’s practical, celebrate everyone’s imperfections, accept trade-offs, and always strive to be relatable. Everything we do is positive, actionable, science-based, bite-sized, and approachable.



Karen Wang, PhD| MSc

Karen knows how confusing environmental health can be. She’s a mom, and when she was pregnant and trying to find out what “natural” and “healthy” really mean, it was easy to get overwhelmed. That’s why she started Because Health. She wanted a source that is based on science and not the latest fads, and that makes the connection between wellness and the environment.

Karen is the editor-in-chief for Because Health content and was the former Director of the Collaborative on Health and the Environment. She also consults on healthy and sustainable building and construction through Inhabit Well. Karen completed her PhD in Strategic Management, a quantitative social science discipline grounded in applied economics and social psychology, at the Foster School of Business at the University of Washington. Karen also holds a MSc in Earth Systems and a BA in Economics from Stanford University.
