Gas stoves creates high amounts of indoor pollution. The amount of pollution gas stoves creates inside are often illegal outside, the US doesn't have indoor pollution standards.
Children living in homes with gas stoves are 40% more likely to develop asthma for example, according to some studies. Other studies have it closer to 10%.
Anyway, it's clear that indoor gas combustion isn't advisable from a health perspective. Not to mention the climate, burning methane for energy should be phased out, full stop.
Those claims have been debunked as being misinterpreted. If you ran a gas stove for 24 hours then yes the amount of NO2 would be illegal outside. But this doesn't consider time-adjusted emissions but rather peak emissions. So you'd have to combine all of that into a single continuous blast, which isn't the case.
As for asthma, current U.S. federal agency involvement on the subject does not identify a connection between cooking with natural gas stoves and the risk of asthma development or direct association with asthma attacks.
Please link some science papers debunking it, something real that isn't just YesToGas lobby talking points. Don't forget US Federal agency recommendations aren't always trustable, especially with lobbying and lots of money involved.
