Food smell sensitivity

Last night was awful, as I was overwhelmed by the tangy and pungent aroma of the dish my brother was cooking. I usually go to bed around 9 p.m., since I’m older, have a heart condition, and need to rest in a peaceful environment. Unfortunately, he finishes work at 7 p.m., gets home around 7:15, and sometimes starts cooking one of his specialty meals around 7:30 or even closer to 8, from a ready-to-cook box delivered earlier in the day. The problem is that for some reason, the very strong smell seemed to linger all night and even into today, which drove me up the wall because I simply cannot relax when I sense something like this. For regular meals it’s usually fine, as the smell dies down within a reasonable time after cooking. I even opened my bedroom windows as wide as possible, which helped, but I could still smell it enough to cause significant stress, and it worried me because I have heart failure and don’t need undue stress. I even used a face mask from a box I originally purchased during the COVID crisis, which helped somewhat, but I still felt stressed because it seemed I was being forced to do something unnatural.

Anyway, I was restless most of the night and decided to have a serious talk with my brother. He was very understanding and promised he would avoid cooking at that hour again, at least not one of those exotic meals. He suggested that in the future he could cook much earlier when I’m up, which seems reasonable, but it depends on how long the smell lingers, as I don’t want to go to bed with a pungent aroma in the air. I think the main issue was the change in routine that unsettled me. Normally, he comes home from work, has a quick meal, and goes to bed early to wake up at 6 a.m., and I’m used to that. This time, though, it was an unexpected event, and the particular dish was overwhelming for me. It might have been more tolerable if I’d been up and about, but lying in bed made it worse because you want to relax and rest but feel like you’re not being allowed to. I also want to clarify that I’ve never been diagnosed as autistic, so maybe it’s not autism that caused this but some other kind of issue—I really can’t be sure. The ironic thing is that my brother says he has a poor sense of smell so can't really appreciate my difficulties.

Anyway, it's good to get it off my chest.


  • Interesting. But not all smells are like this. Other smells I hate are- dogs, generally animals. Horses, mice, cows etc. I can't breathe, I feel nauseous, often also get headache. Others wonder why I overreact.

    When it comes ti food, I remember going through hel when I worked in McDonald's. Especially the frying devices and oil. 

  • Yes, I read somewhere that in the autistic brain, smells are uncensored and go directly to the limbic region, so it’s no wonder you have to lock yourself behind doors, Alien0n3arth. The trouble is, your husband simply can’t understand what it’s like for you.

  • When my husband cooks or fries beef I lock myself behind few doors and still struggle to breathe. He has more of such smelly dishes. I can't be in the kitchen when he cooks. And I can't cook for him.

  • Hi Lotus,

    I've ordered one from Amazon - WINIX 5500-2 Air Purifier. It's pricey at £160 but it it does the job then that's ok.

  • I understand how you feel. We live in an apartment block and sometimes get the smell of frying onions or garlic coming in through either our window or the gaps around our front door, and that is also unpredictable and causes us to feel stressed. I have bought a neutradol gel air freshener to try when it happens again.

    Thank you  for the suggestion of an air purifier. I have seen a Spear & Jackson one on both the Argos and Amazon websites for around £40. So if we keep getting smells coming in and the neutradol doesn't work I might try that.

  • Thanks a lot, Bunny. I will look into that.

  • I'm sorry you had such a bad night. Hopefully, your brother's cooking won't bother you in the same way again, given his kind understanding and promise. But perhaps an air purifier is something that you could consider in future, if need be, whether due to his cooking or any other sources of strong smells.

    According to Which?, an air purifier with both a HEPA filter and a carbon filter (also known as a charcoal or activated carbon filter) can remove cooking smells.
