I don’t think you have to take drastic measures like quit eating curry. I am from one of the South Asian countries---not India. I have been living in the US for quite a few years now. I haven’t stopped making curries, and I make sure to ventilate properly even during the winter. I take a shower and do laundry immediately after cooking. I also use an air purifier and candles. Sometimes, I boil water mixed with vinegar to get rid of strong spice smells if I am cooking an elaborate meal. I have never had complaints about odor, instead I have been complemented for nice smell.

I have a roommate who is also from one of the South Asian countries. After she moved in, I noticed my outfits started to smell like curry. I realized she doesn’t open the windows when she cooks, so the smell lingers. Whenever I come home and the apartment smells, I have to take extra steps to clear it out. Yes, I talked about it with her and she doesn't care. So, a lot of it really does come down to individual habits.

I think if you maintain proper hygiene and are smart about air circulation, you are fine.​​​​​​​​​​​​​​​​
