Why do bad smells or burnt smells (garbage, burnt popcorn, vomit) cause headaches?
Hi, Great question. In fact any strong odor GOOD or BAD can ‘trigger’ a headache, if you are one of those lucky people who are sensitive to this kind of environmental stimulus. In an article, by AOL Health, strong aromas are one of the top 10 triggers for headaches. See the other typical causes in the article here: http://www.aolhealth.com/condition-center/headaches-migraines/causes-surprising So, for those people who may suffer from frequent (or also migraine type headaches, which are different than typical headaches) – it’s really valuable to identify any specific odors that might be your own individual culprits. For me – I cannot go into one of those ‘Yankee’ Candle shops – very nice place – but way too pungent.
