something that helped my indian friends and as a person that had an indian roommate -

keep your clothes away from wherever you’re making food so the smell doesn’t get on your clothes. this also includes jackets, backpacks, anything that will carry smells. close your door while making food too if it’s close enough for the smell to travel there, even open windows if you can. the smell of food will also get in your hair, do with that information as you will lol

also when you eat spicy foods you’ll sweat out the spices so the only way to cut back the natural odor from that is to cut back on those foods. or you can just try to drink as much water as you can to flush it out of your system but it’s better to solve the problem at its source.

my roommate also showered like 2-3 times a day and never smelled bad but i know that’s a lot to ask of someone in CS lmao
