hey shelter,

its all coz of our food habit, as we use lot of spices

so use in moderate amount,

and make sure that u dont go out with the same clothes u use while cooking,

and while cooking make sure that u clsoe the door of u r bedroom and closet, where u put your clothes,

and when u do your laundry, use fabric softener with fragrance,

thats all  i can think of, hope u will get more suggestions
