Of course reducing toxic exposures is an important way to reduce risks from unhealthy chemicals, but a growing body of research suggests paying attention to positive habits – such as good food, healthy sleep and active play can often reduce or even eliminate harm when exposed.
An update on this emerging field of research appeared in October 2011 in the NIH journal Environmental Health Perspectives, focusing on the physical effects of stress and relaxation.
Psychological stress can change how chemicals affect the body. Stress has been demonstrated to change the effects of lead exposure and of exposure to air pollution in children. But much remains to be learned about other chemicals and other types of exposures. And about how this all works.
We know that some stress is good for children; a little adrenaline or cortisol can fuel kids to reach new heights of achievement. And we know that when stress becomes too prolonged, too severe or too frequent the immune system can be altered in a way that increases the impact of chemical pollution.
Sadly, sometimes the most stressful environments are also the most polluted.
In January 2011, Science to Achieve Results (STAR) research grants totaling $7 million were awarded by the EPA to work on new approaches to understanding how stress changes what happens when kids are exposed – and what we can do about it.
I’m excited about this, and expect it to uncover valuable new knowledge. But in the meantime, common sense makes sense.

And do what it takes to minimize un-useful stress. Have fun together!
