Fish odor

A seafood allergy is not uncommon. It is estimated that one in every 200 people is allergic to seafood.

This type of allergy is triggered when seafood is being cooked.  People with this kind of allergy react to the vapors and steam being produced from said cooking.

Fish and seafood release a certain kind of protein called amines during cooking. This causes allergies on the airways and lungs of certain individuals.

While avoiding the consumption of fish or seafood can be easy, accidental exposure to its odor may result in serious trouble.


A very rare form of physical urticaria is caused by vibrations.

For people, who suffer from this condition known as vibratory urticaria, coming into contact with something that vibrates can cause swelling, itching, headaches, and blurry vision.

Researchers said that this kind of an allergy can trigger the release of inflammatory substances into the body causing hives and rashes.

Simple acts such as clapping of the hands, running, traveling or the use of a drill can trigger this kind of an allergy.

Continuous vibrations that last for an hour or less can result in self-consciousness and discomfort.
