Tear gas works by binding to receptors in the eyes, nose, and throat. These receptors are called TRPA1 receptors. TRPA1 receptors are activated by a variety of irritants, including tear gas, wasabi, and cinnamon. When TRPA1 receptors are activated, they send a signal to the brain that causes the eyes to water, the nose to run, and the throat to constrict.
Tear gas can also cause other symptoms, such as coughing, sneezing, and difficulty breathing. In some cases, tear gas can even be fatal.
How to protect yourself from tear gas
There are a few things you can do to protect yourself from tear gas. These include:
* Wear a gas mask. A gas mask will prevent tear gas from coming into contact with your eyes, nose, and throat.
* Cover your eyes, nose, and mouth. If you don't have a gas mask, you can try to protect yourself by covering your eyes, nose, and mouth with a cloth or your hands.
* Flush your eyes with water. If you are exposed to tear gas, flush your eyes with water as soon as possible. This will help to remove the tear gas and reduce irritation.
* Seek medical attention. If you experience severe symptoms after being exposed to tear gas, seek medical attention immediately.
Tear gas is a dangerous chemical that can cause serious health problems. If you are ever exposed to tear gas, it is important to take steps to protect yourself.
