Gas ovens work by mixing natural gas and air to produce heat. When the thermostat is set, a fuse lights the gas as it seeps through a burner snaking inside the oven. The burner has multiple holes in it for the lighted gas to escape from, allowing the heat to spread throughout the oven's interior. Modern gas ovens have electric pilot ignitions that create a small, continuous flame that increases in temperature and height by twisting a corresponding knob to the area in use4. The temperature of the oven stays consistent throughout the entire cooking period.
Gas ovens are not necessarily going to cause asthma. You can mitigate the amount of air pollution that they produce but having a gas oven doesn't necessarily mean a child will develop asthma or that they will even be the cause. Florida has a very small amount of gas stoves and yet have a median share of asthmatic children. There's too many other factors that can effect the data link to say for sure that gas ovens are a leading cause.
I'd say compulsively spritzing Febreze would have more to do with asthma than gas ovens, but I know a bunch of Karen's that still go through a costco pack of the stinky fucking things a month, all over the furniture their kids eat, play and sleep on.
Yeah, which is why you shouldn't use strong household cleaners around kids, and should only use it with proper ventilation and a respiratory device if warranted. And smoking is bad, don't do it around your kids.
