Odors and Scents Can Trigger Headaches

PERFUMES AND OTHER CHEMICALS AS A CAUSE OF HEADACHES “OSMOPHOBIA”

WHEN SMELLS HURT

Is the person sitting next to you causing your headaches? Perhaps it is their cologne or perfume. Odor-triggered headaches are fairly common. Other common triggers include cigarette smoke, fumes from cleaning products, cars, candles, incense, air fresheners (sadly, sometimes the things that can help make people feel better), and, occasionally, the smell of certain foods, like fried fish, garlic, and even onions, can cause headaches.

Once in a while, the smell that is causing the headaches is imagined. These types of olfactory “hallucinations”  are often associated with migraine auras (see migraines below) and are caused by anxiety. It can be accompanied by allodynia (oversensitivity to physical stimulation/touch).

Headaches due to chemicals typically occur after 15 minutes (or longer) of exposure. Once the stimulus is removed, the headache usually goes away within minutes to hours.

Osmophobia often appears when the sinus becomes irritated or when chemicals induce vasodilation within the brain. Again, vasodilation causes pressure on the adjacent nerves, causing a headache.
