Some people are very sensitive when it comes to things such as perfumes, diesel, petrol, smoke and so on. These can be very dangerous smells to the ones that are allergic to them and some even have multiple chemical sensitives. You can also have mild to chronic sensitivities.

There are a lot of signs with chemical sensitivities and so many of them won't be listed here but here are some:

Doctors often give medications to patients that suffer with chemical sensitivities. These medications they give are a lot of times year round or during certain seasons.
