Strong odors can be toxic for those who have migraines. This is because they might be more sensitive to smells around them. Due to the activation of certain pain and scent receptors, inhaling strong fumes can create a heightened sensation in their brain. This can lead to severe headaches and dizziness. So, staying cautious of such smells can be helpful for those prone to migraines. Here are five substances with strong odors that can trigger migraines.

Scented products

Those who constantly have migraines might be allergic to scented products. These products have distinct and strong odors that can trigger migraines. Their scents can swell up blood vessels, which leads to stimulation of the brain’s nervous system. This can cause intense headaches. Also, note that scented products are not limited to perfumes in alluring glass bottles. Fragrant candles, soaps, detergents, flower bouquets, and air fresheners can cause headaches and dizziness too.

Smoke from cigarettes

Sensitivity to cigarette smoke can trigger migraines. Cigarettes have nicotine that contracts the blood vessels and decreases the blood flow to the brain. This pulls down the overall brain activity that can trigger painful migraines. The back of the head and face can begin to hurt too. This is because the blood reaching the covering of the brain, also known as meninges, decreases. Avoiding restaurants and other public places that permit smoking can reduce the chances of a migraine headache.

Oil-based paint

Most oil-based paint products have volatile organic compounds, also known as VOCs. These are solvents that are released into the air once the paint is applied to a surface. When odor from the paint is inhaled, VOCs can cause symptoms like dizziness and headaches. Luckily, this migraine trigger can be avoided by opting for paints that have a lower amount of VOC. Many companies also make water-based and odor-free paints, which are better alternatives to oil-based paints.

Gasoline

Gasoline is refined petroleum that has a colorless, light brown, or pink hue. The vapor released by gasoline is strong, and if inhaled, can cause blood vessels to dilate. This can slowly lead to a throbbing migraine, leaving the head feeling heavy. Typically, gasoline contains around 150 chemicals, which is why it is toxic for migraine patients. Using nose plugs can help if you work at or come across places like petrol stations that usually have gasoline pumps.

Car exhaust leak

A car exhaust leak emits a smell that is strong. Inhaling the harmful gases emitted by the leak can have a huge impact on migraine patients. These leaks can build up high amounts of carbon monoxide (CO gas) over time. If CO gas fumes enter the body, it can lead to various symptoms like headaches, nausea, shortness of breath, and dizziness. Always be cautious while checking the car exhaust. Make sure you are equipped with a protective gear to reduce the chances of a migraine attack.
