Replacing gas stove can help asthmatics as much as some drugs, US experts find (www.theguardian.com)

A US study has found a 70% drop in hospital admissions and days off from work or school when people with poorly controlled asthma had their gas stove and hob replaced with electric.

Ohio’s publicly owned MetroHealth began the study in December 2024 but funding was terminated early by the incoming Trump administration. It had been designed to investigate if replacing gas cooking improved asthma for 1,200 people living near Cleveland, Ohio.

Prof Ash Sehgal of Case Western Reserve University, the project’s leader, said: “We had completed the project at fewer than 100 households. As a result, over 1,100 households were unable to benefit. We also had to lay off about 20 project staff.”

The team finished the stove replacements that were under way and closed the project, but to the researchers’ surprise, the benefits could be clearly detected even in the scaled-down study of 72 homes.

Sehgal said: “We were surprised when we analysed the results and found a very large effect size. The improvements in asthma symptoms following stove change were similar to – or even greater than – those reported in clinical trials of commonly used asthma medications.”

Air pollution was measured in 44 of the homes. On average, nitrogen dioxide dropped 70%.

piss poor science.

No control group.

No accounting for ventilation use.

Independent research (including a 2024 study in Nature and data from Consumer Reports) has shown that while many people do under-utilize hoods, properly functioning, outside-venting range hoods can reduce nitrogen dioxide (NO2) levels by 50–70%—comparable to the reduction achieved by swapping stoves.

And would it hurt to open a freaking window and get some cross ventilation in the kitchen???
