Are dirty chemicals making kids more hyper?
Effects of single and multiple endocrine-disrupting chemical exposures on hyperactivity trajectories among preschoolers: A cohort study.

Surprising Findings
The effect of chemical mixtures was stronger than individual chemicals, and only became significant when all were above the 55th percentile.
It suggests a threshold effect—low levels of many chemicals together may suddenly become risky once they cross a certain level, which challenges current safety models.
Practical Takeaways
Reduce children’s exposure to multiple endocrine-disrupting chemicals by choosing fragrance-free, plastic-free, and organic products when possible.

Kids exposed to several hormone-disrupting chemicals at once are more likely to show high levels of hyperactivity as they grow, with the risk more than doubling compared to lower exposures.
Some chemicals we're exposed to might be linked to hyperactivity in young kids — some could make it more likely, others less, and it depends on the specific chemical.
When little kids are exposed to higher levels of certain chemicals found in everyday products — especially when many of them are high at once — they’re more likely to show increasing hyperactivity as they grow.
Girls might be more affected by certain chemicals early in life when it comes to developing hyperactivity, compared to boys.
Kids who are exposed to certain chemicals in the environment might become more hyperactive.
