How Does Chemistry Affect Our World?

To be exact, chemistry is everywhere. We are made of chemicals and everything we taste, smell, touch, see, and hear involves chemistry and chemicals. Tasting, smelling, touching, seeing and hearing all include complicated series of chemicals reactions and interactions in our body. And lots of change we eye in the world surrounding are created by chemical reactions.

If you still think that chemistry is at laboratories or beakers, you are wrong because it’s around us. And the better you know chemistry, the better you understand the world.

Importance of chemistry – What you should know

First of all, please understand that chemistry is the study of atoms, molecules, and combinations that make up the matter in the universe, consisting of the ways they combine, change, and interact to create new ones.

However, to some people, chemistry is believed as a complex and boring science since they have to apply logic and math in studying chemistry. So, do you think that fireworks or explosions are boring? Of course, not, right? When you understand the basics of how the matter works, you feel enthusiastic in the study of chemistry.

It’s time to look at some explanations below to know the importance of chemistry!


You’re using chemistry to decide which cleaner is good for yourself, dishes, clothes, home, etc. You apply chemistry when using disinfectants, bleaches and even mixing soap and water together.


Learning about chemistry helps you understand how food changes when you cook it, how to preserve food, how the food spoils, how your body consumes the food, how ingredients mix to make food and so on.


When you are aware of the basic chemistry, you will understand how drugs, vitamins, and supplements can help or damage your body. Besides, developing and testing new medical medicines and treatments is related to the study of the chemistry.

Environmental issues

Do you know that the chemistry is at the essence of environmental issues? What makes a chemical a pollutant and another chemical a nutrient? Is there any chance to clean up the environment? How can we produce the things we need without damaging the environment? And so on.

The truth is that you can be a chemist because you use chemicals every day and do chemical reactions without noticing much about them such as breathing, eating, or sitting somewhere to read this article. Even your body is made of chemicals as well.

In a word, every matter is made of chemicals and the importance of chemistry is the study of everything on Earth.

Continue taking a glance at chemistry in our daily life

Now, you easily recognize that chemistry is an essential part of your daily life as well as how it affects the world, right? You find it in the air you breathe, the food you eat, the objects you touch, your emotions, and so on. Let’s check now interesting examples that prove chemistry in everyday life.

View your body

We all know that the body is mostly water which is oxygen and hydrogen. Nearly 99% of the mass of your human body is made of 6 important elements including oxygen, hydrogen, calcium, carbon, phosphorus, and nitrogen. Only 0.85% is formed by five other elements such as sodium, magnesium, Sulphur, potassium, and chlorine. Of course, all these elements are necessary to your life.

Feel your emotions

In a day, you can experience different emotions like excitement, envy, jealousy, infatuation, etc. And they are a result of chemical messengers, mainly neurotransmitters. For instance, the feeling of being in love is due to an acceleration of dopamine and phenylethylamine. Or the pounding heart and sweaty palms of infatuation are caused by a high level of norepinephrine.

Your eyes tear when cutting onions

The onions are harmless. But when you cut an onion, your eyes might burst of tears. Why?

After slicing into an onion, amino acid sulfoxides create sulfenic acids. Then enzymes are free to combine with the sulfenic acids to form propanethialS-oxide. It’s a volatile sulfur compound that floats upwards towards your eyes. Next, it reacts with the water in your tears in order to create sulfuric acid. Since this acid burns and stimulates, your eyes need to release tears to remove the irritant.

How to stop crying?

Putting the onions in the refrigerator before cutting will slow reactions and alter the chemicals inside the onions. Or try using a stainless steel or cut them in water.

Clean with soaps

Soaps are made of potassium or sodium fatty acids salts. In a chemical reaction, particularlysaponification, these chemical elementsareknown to create from the hydrolysis of fats. Thanks to a capacity of working as an emulsifying agent, soap is able to scatter one liquid into another immiscible liquid. That means when oil/dirt doesn’t naturally combine with water, using soap can delay and then remove it effectively.

Apply sunscreen on the skin

Before going out in sun or lying on a beach, we often use sunscreen to prevent the ultraviolet rays from damaging your skin. So, how does it work and what an SPF rating means?

Sunscreen mixes inorganic and organic chemicals to filter the sunlight in such a way that less of it arrives at the deeper layer of the skin. Similar to a screen door, although some light might penetrate, not as much as it can reach the skin at all.

SPF means Sun Protection Factor. It’s a number that points out how long you can stay in the sun before getting a sunburn. Commonly, your skin has a natural SPF which is determined by the amount of melanin or how darkly pigmented your skin is.And using the sunscreen is an extra.

For instance, if you’re going to stay out in the sun about 15-20 minutes before burning, the sunscreen with SPF of 10 will be an ideal choice. It’s because it will resist the burn about 150 minutes.

Cook quicker in a pressure cooker

A pressure cooker is designed with an intricate lid that seals the pot totally. When boiling the water, the steam can find no way to escape. Therefore, it stays inside and begins to enhance the pressure. Under this pressure, the temperatures will increase much higher than normal conditions, making cooking faster.

Colorful vegetables

Do you know why fruits and vegetables are highly colored? It’s because they include a particular kind of chemical compound, called carotenoids. Also, these compounds have an area called chromophore, which takes in and gives off specific wavelengths of light, creating the color that you see.
