A migraine is often characterized by throbbing pain on one or both sides of the head, with an intensity that increases as time goes on. Migraines affect both men and women, and tend to be experienced more in middle age. Various triggers cause migraines, including certain lights, sounds, and even smells. In fact, it’s estimated that odors cause nearly fifty percent of migraines.

Here are some common odors and scents that can trigger migraines:

1. Air fresheners

Air fresheners have been linked to migraines for many individuals, as they contain strongly scented chemicals. These can irritate the sinuses, resulting in swelling that can trigger a migraine. It is vital to read the manufacturers guideline before using air fresheners to check for ingredients that may cause a migraine.

2. Cigarette smoke

Cigarette smoke is a proven cause of migraines. As smoke enters the body, it causes blood vessels to constrict. The narrowed blood vessels restrict blood flow to the brain, leading to migraines. As we know, cigarettes also contain a harmful substance known as nicotine, another contributing factor to migraine episodes.

3. Perfume and cologne

Everyone likes to smell good, and many of us use perfume or cologne to achieve this. However, the strong scent of these products can sometimes trigger migraines. Exposure to strong perfumes can cause inflammation of the sinuses, another cause of migraines. One way to handle this issue is to avoid wearing fragrance, or stepping out to get fresh air if someone near you is wearing perfume.

4. Cleaning chemicals

Cleaning chemicals are sometimes used too much in our homes. Especially when cleaning inside, the chemicals in these products can trigger migraines. If you notice a certain cleaner is causing migraines, try switching to a more natural alternative, and always keep windows open and fans on while cleaning. If your symptoms persist after coming into contact with certain cleaning products, seek medical attention.

5. Food odors

Strongly smelling food can also cause migraines. If you have an aversion to a certain food, smelling it could cause a negative reaction. Restaurants with strong food odours can also be a trigger. If you notice a certain smell or situation that causes migraines, try to reduce your exposure to it.

The different smells listed in this article have all been linked to migraines, but you may find that certain ones are more or less likely to be a trigger for you. Keep track of what causes your migraines and seek medical attention if your migraines become frequent or unmanageable.
