In addition to being used in a wide range of recipes, such as omelettes and soup, onions can also be chopped, sautéed, and fried.
Cooks generally concur that the effort put into the dish pays off, but they also point out that chopping and slicing these delicious bulbs frequently causes watery eyes and a runny nose.
You are crying your eyes out while cutting onions, yet you are not feeling anything. Being exposed to anything irritable triggers a reaction that causes these tears.
Why does the smell of onions make you want to cry?
Onions are essentially underground-growing bulbs. Voles and other animals that enjoy chewing on roots, tubers, and bulbs for sustenance live in the soil where onions are grown. A good source of protein is onions.
In order to prevent being eaten by predators as they grow, onions are said to have a defence mechanism built into them, according to Healthline. This is carried out in an effort to stop something similar from happening.
When an onion’s skin is pulled off, enzymes and sulfenic acid are released into the air. Propanethial S-oxide is a gas that can be dangerous when these two substances are combined.

Propanethial S-oxide is a lachrymatory substance, which means that when it comes into contact with the eye, it makes people cry. When propanethial S-oxide interacts with the aqueous layer that covers and protects the eyes, sulfuric acid is created as a result of this contact.
Your eyes, however, contain a defence system that tries to keep them from harm, much to how onions defend themselves. The nerves in each eye produce tears to wash away any lachrymatory compounds they uncover, according to a MedicalNewsToday article.
Some people experience the waterworks more frequently than others when cutting onions. If you are allergic or sensitive to onions or other alliums, your reaction could be more severe and your symptoms could be more noticeable.
Sulfur is a component of many chemicals found in onions, and it is this element that causes the chemical reaction that is the most powerful. These onions are available in a range of hues, such as red, white, and yellow.
