The EPA halted a study on gas stoves and asthma. But even partial results were striking.

Removing their gas stoves relieved study participants’ asthma so much that the results were clear even with only 85 of them.

A simple kitchen upgrade, swapping gas for electric, may do as much for asthma sufferers as the drugs they take every day, researchers have found. The change is not a cure, but an exposure-reduction strategy that may complement existing treatments.
