Did you know that some smells cause headache?
Its true, the intoxicating or stupefying fragrances of some perfumes and room fresheners are some of the odors, that if you inhale them long enough, you will find that these smells cause headache. This need not be something that you have used on your own body. It can be a perfume that your neighbour has used. So if you sit next to person and feel that your head is getting woozy, try to move to a safe distance away. Maybe 5 or 10 feet away if necessary!
