There are a variety of chemicals that can give you headaches. Some of the most common include:
-Tobacco smoke
-Exhaust fumes
-Paint fumes
-Cleaning products
-Perfumes/colognes
-Hairspray
When these chemicals are inhaled, they can irritate the membranes lining the nose and throat. This irritation can lead to inflammation, which in turn can cause headaches. In some cases, the headache may be accompanied by nausea, dizziness, or lightheadedness.
