Can onions cause headaches?
I have noticed that if someone cooks onions, I get a headache. Sometimes just diced onion causes headaches, but cooking especially. Even if I am far off from the kitchen, I still get nasty headaches. Also fatigue and possibly irritability as well.
I never eat onions because I
don’t like hate them. But recently even the smell is too much. I have a very acute sense of taste and olfaction.
If I was sleeping I’ll wake up to the smell and already have a headache. If awake, I’ll know almost immediately that someone is cooking onions in the house, first with a headache then the smell.
Is this an allergic reaction or something else? Have you ever heard of smell alone causing a headache?
