Objective: We conducted a questionnaire survey to clarify the relationship between osmophobia in people with migraine and headache caused by the smoke and odor of heated tobacco products.
Methods: A questionnaire survey was conducted on the internet. The subjects were people with headache aged from 20s to 40s, and they were not limited to heated tobacco users.
Results: The number of valid responses was 627, which included 163 with migraine. In the migraine group, 77 had concomitant osmophobia and 86 did not. More migraine people with osmophobia had photophobia, phonophobia, and allodynia compared to patients with migraine without osmophobia. People with osmophobia had more discomfort, cough, sputum, nausea, odor sensitivities and headache than those without it by exposure to odor or smoke of heated tobacco products.
Conclusions: It has been found that migraine people with osmophobia are more likely to have headaches due to the smoke and odor of heated tobacco products. It is considered necessary to improve the quality of life of headache people by improving the smoking cessation environment.
