Various odors and fragrances surround us, but not everyone is tolerant of them. Especially for people with migraine, different strong smells can act as a trigger because of smell sensitivity. Inhalation of these strong odors can lead to dizziness, headaches and other health issues. One can also look for ways to prevent a migraine attack due to such odors. Here are some odors that can be toxic to people with migraine: Car exhaust Car exhausts are among the leading cause of environmental pollution. The gas leak from car exhausts is therefore understandably harmful. The leak has a very strong odor and can be the reason for high CO or carbon monoxide gas buildup over time. These fumes often cause nausea, shortness of breath, headaches, and dizziness. Cleaning supplies Cleaning supplies often contain Volatile Organic Compounds or VOCs. These emit gases that may or may not have a strong smell. Exposure to these gases can cause headaches and respiratory issues. They are considered toxic and are often the reason for migraines. Additionally, VOCs can also turn out to be carcinogenic for some people. Therefore, it is essential to use VOC-free cleaning products. Oil-based paints Oil-based paints also contain VOCs. These solvents get released into the environment once the paint is applied on any surface.
